  • Vocal Cord Dysfunction: Analysis of 27 Cases and Updated Review of Pathophysiology & Management Original Research

    George, Shibu; Suresh, Sandeep

    Resumo em Inglês:

    Abstract Introduction Vocal cord dysfunction is characterized by unintentional paradoxical vocal cordmovement resulting in abnormal inappropriate adduction, especially during inspiration; this predominantly manifests as unresponsive asthma or unexplained stridor. It is prudent to be well informed about the condition, since the primary presentation may mask other airway disorders. Objective This descriptive study was intended to analyze presentations of vocal cord dysfunction in a tertiary care referral hospital. The current understanding regarding the pathophysiology and management of the condition were also explored. Methods A total of 27 patients diagnosed with vocal cord dysfunction were analyzed based on demographic characteristics, presentations, associations and examination findings. The mechanism of causation, etiological factors implicated, diagnostic considerations and treatment options were evaluated by analysis of the current literature. Results There was a strong female predilection noted among the study population (n = 27), which had a mean age of 31. The most common presentations were stridor (44%) and refractory asthma (41%). Laryngopharyngeal reflux disease was the most common association in the majority (66%) of the patients, with a strong overlay of anxiety, demonstrable in 48% of the patients. Conclusion Being aware of the condition is key to avoid misdiagnosis in vocal cord dysfunction. Fiberoptic laryngoscopy is the diagnostic gold standard to demonstrate paradoxical vocal cord adduction during an attack. Amultidisciplinary approach should be adapted for the management, which should be specific and tailored for individual patients.

    Moretti, Claudia; Ribas, Angela; Guarinello, Ana Cristina; Rosa, Marine; Riesemberg, Renato; Vassoler, Trissia; Sypczuk, Giselle; Martins, Jackeline

    Resumo em Inglês:

    Abstract Introduction Cochlear implants are currently the most effective technological resource to facilitate access to the hearing world for deaf people. Their use, especially when implanted early in children, reduces the impact of deafness on hearing as well as on the development of spoken language. Objective To validate the first part of the Brazilian Scale of Hearing and Language Development (EDAL-1, in the Portuguese acronym) and to establish the normal curve in infants and children aged between 0 and 24 months old with normal hearing. Method This is an experimental study of a descriptive nature, conducted with 92 infants and children with normal hearing. Every infant/child was evaluated audiologically, and the EDAL-1 was applied to their parents. The responses were categorized by applying the EDAL-1 every 3 months for each child. Results The EDAL-1 was shown to be easily applied by the researcher and easily understood by the parents. It was possible to classify the sample every 3 months and describe the results. The average of the responses found in terms of scores for each age category shows an increasing scale following the evolution of the chronological age: 3 months-34.23 points; 6 months-54.68 points; 9 months-73 points; 12 months- 82.5 points; 15 months-87 points; 18 months-91 points; 21 months-92.5 points, and 24 months-95.83 points. Conclusion The normal curve for EDAL-1 was successfully established. The averages can be considered as the standard protocol for normality, serving as a reference for comparison with other populations.
  • Surgeon Oriented Preoperative Radiologic Evaluation in Cochlear Implantation - Our experience with a Proposed Checklist Original Research

    Mandour, Mahmoud; Tomoum, Mohammed; Zayat, Saad El; Hamad, Hisham; Amer, Mohamed

    Resumo em Inglês:

    Abstract Introduction Preoperative temporal bone imaging studies have been routinely performed prior to cochlear implantation. Radiologists need to report these examinations with special focus on the surgeon’s expectations. Objectives To provide a basic structured format, in the form of a checklist, for reporting preoperative computed tomography (CT) and to its clinical impact on operative findings. Methods The preoperative temporal bone CT scans of 47 patients were analyzed and reported according to the proposed checklist. Intraoperative assessment of mastoidectomy, posterior tympanotomy and round window access was done by the surgeon in a blinded fashion and were correlated with the radiological findings to assess its significance. Results The proposed radiological checklist was reliable in assessing operative difficulty during cochlear implantation. Contracted mastoid and lower tegmen position were associated with a greater difficulty of the cortical mastoidectomy. Presence of an air cell around the facial nerve (FN) was predictive of easier facial recess access exposure. Facial nerve location and posterior external auditory canal (EAC) wall inclination were predictive of difficult round window (RW) accessibility. Conclusion Certain parameters on the preoperative temporal bone CT scan may be useful in predicting potential difficulties encountered during the key steps involved in cochlear implant surgery.

    Ferreira, Dulce Azevedo; Bueno, Claudine Devicari; Costa, Sady Selaimen de; Sleifer, Pricila

    Resumo em Inglês:

    Abstract Introduction The Mismatch Negativity (MMN) auditory evoked potential evaluation is a promising procedure to assess objectively the ability of auditory discrimination. Objective To characterize the latency and amplitude values of MMN in children with normal auditory thresholds and without auditory complaints. Methods Children between 5 and 11 years old participated in the present study. All participants underwent acoustic immittance measurements and tonal and vocal audiometry. The MMN was recorded with the MASBE ATC Plus system (Contronic, Pelotas, RS, Brazil). The electrodes were fixed in Fz (active electrode), Fpz (ground electrode) and in M2 and M1 (references electrodes). The intensity used was 80 dBHL, the frequent stimulus was 1,000 Hz and the rare stimulus was 2,000 Hz. The stimuli were presented in both ears separately. Results For the female group, the mean latencies and amplitude of MMN were 177.3 ms and 5.01 μV in the right ear (RE) and 182.4ms and 5.39 μV in the left ear (LE). In the male group, themean latencies were 194.4 ms in the RE and 183.6ms in the LE, with an amplitude of 5.11 μV in the RE and 5.83 μV in the LE. There was no statistically significant difference between ears (p = 0.867 - latency and p = 0.178 - amplitude), age (p > 0.20) and the gender of the participants (p > 0.05). Conclusion Using the described protocol, the mean latency value of MMN was 184.0 ms for RE and 182.9 ms for LE, and the amplitude was 5.05 μV and 5.56 μV for the left and right ears, respective.

    Balsalobre, Leonardo; Pezato, Rogerio; Mangussi-Gomes, Joao; Gregorio, Luciano; Haddad, Fernanda Louise Martinho; Gregorio, Luiz Carlos; Fujita, Reginaldo

    Resumo em Inglês:

    Abstract Introduction It has been hypothesized that increasing the interstitial hydrostatic pressure within the sinonasal mucosa of patients with nasal polyposis (NP) might decrease the size of nasal polyps. Objective To evaluate the effects of positive airway pressure, delivered by a continuous positive airway pressure (CPAP) device, in patients with NP and in control subjects. Methods Twelve patients with NP and 27 healthy subjects were exposed to CPAP (20 cm H2O) for 2 hours. Visual analog scale (VAS), Nasal Obstruction Symptom Evaluation (NOSE) scale, acoustic rhinometry (AR), peak nasal inspiratory flow (PNIF) and nasal endoscopy (NE-Meltzer polyp grading system) were performed before and after the intervention, for all patients. Results The control group showed a significant worsening in nasal obstruction symptoms, as measured by VAS and NOSE (p < 0.01), and a significant decrease in nasal patency, as measured by the PNIF and AR (p < 0.01). For the NP group, VAS, NOSE, and AR did not differ significantly (p = 0.72, p = 0.73, and p = 0.17, respectively), but PNIF values worsened (p = 0.04) after exposure to CPAP. There was a statistically significant reduction in the nasal polyps’ size (p = 0.04). Conclusions Positive pressure worsened the nasal obstruction symptoms and decreased objective parameters of nasal patency in control subjects. In patients with NP, exposure to CPAP reduced the nasal polyps’ size, and the nasal patency, asmeasured by PNIF. However, it had no significant effects in AR and in nasal obstruction symptoms.

    Musa, Emmanuel; Kodiya, Aliyu Mohammed; Kirfi, Abdullahi Musa; Nwaorgu, Onyekwere George B.

    Resumo em Inglês:

    Abstract Introduction A common practice in the management of patients with chronic rhinosinusitis (CRS), the empirical use of antibiotics may contribute to treatment failure and to the development of antimicrobial resistance. Objective To determine the antibiotic sensitivity pattern of aerobic and anaerobic bacteria associated with CRS. Methods This was a prospective cross-sectional study in which endoscopically guided middlemeatal swabs (IBMSpss, version 16.0, Chicago, IL, USA) were aseptically taken from patients diagnosed with CRS after obtaining informed consent and ethical clearance. The samples were sent to the laboratory for qualitative and semiquantitative analysis via gram stain, aerobic, anaerobic cultures and antibacterial sensitivity tests. The collected data was analyzed using SPSS for Windows, version 16 (SPSS Inc, Chicago, IL, USA). Simple statistical parameters and paired sample t-test were used, as appropriate. Results There were 74 (56.92%) bacterial growths, out of which 55 (74.32%) were aerobic and 19 (25.68%) were anaerobic isolates, from a total of 130 patients. About 13 (17.5%- 18%) of these bacterial growths yielded a mixed growth of aerobic and anaerobic isolates. Themost common bacterial isolates were 26 (35.14%) Staphylococcus aureus, Haemophilus influenzae 9 (12.16%), Streptococcus viridians 8 (10.81%), and Streptococcus pneumoniae 5 (6.76%). Augmentin, ciprofloxacin, and Peflacine were found to bemost effective, followed by levofloxacin, Rocephin, erythromycin and Zinat in that order. Conclusion Augmentin, ciprofloxacin and Peflacine have a sensitivity of 100%, while most of the organisms show resistance to Ampiclox, amoxicillin, and Septrin.

    Reis, Flavia Mara Fernandes da Silva; Gonçalves, Claudia Giglio de Oliveira; Conto, Juliana De; Iantas, Milena; Lüders, Débora; Marques, Jair

    Resumo em Inglês:

    Abstract Introduction Hearing is the main sensory access in the first years of life. Therefore, early detection and intervention of hearing impairment must begin before the first year of age. Objective To analyze the results of the electrophysiological hearing assessment of children at risk for hearing loss as part of the newborn hearing screening (NHS). Methods This is a cross-sectional study held at a hearing health public service clinic located in Brazil, with 104 babies at risks factors for hearing loss referred by public hospitals. A questionnaire was applied to parents, and the auditory brainstem response (ABR) test was held, identifying those with alterations in the results. The outcome of the NHS was also analyzed regarding risk factor, gestational age and gender. Results Among the 104 subjects,most of them weremale (53.85%), and the main risk factor found was the admission to the neonatal intensive care unit (NICU) for a period longer than 5 days (50.93%). Eighty-five (81.73%) subjects were screened by NHS at the maternity and 40% of them failed the test. Through the ABR test, 6 (5.77%) infants evidenced sensorineural hearing loss, 4 of them being diagnosed at 4months, and 2 at 6 months of age; all of them failed the NHS and had family history and admission atNICU for over 5 days as themost prevalent hearing risks; in addition, familymembers ofall children perceived their hearing impairment. Conclusion Advances could be observed regarding the age of the diagnosis after the implementation of the NHS held at the analyzed public service clinic.

    Carnevale, Claudio; Arancibia-Tagle, Diego; Sarría-Echegaray, Pedro; Til-Pérez, Guillermo; Tomás-Barberán, Manuel

    Resumo em Inglês:

    Abstract Introduction Granulomatosis with Polyangiitis (GPA) is a small vessel vasculitis characterized by a necrositing granulomatous inflammation of the upper and lower respiratory tracts and focal/proliferative glomerulonephritis. In more than 70% of the cases, the presenting symptoms are head and neck manifestations that are often misdiagnosed as infectious or allergic in etiology. Objective The present study provides an analysis of head and neckmanifestations in a series of patients diagnosed with GPA. It also evaluates their medical and surgical treatment and provides a review of the relevant literature. Methods A retrospective analysis of 19 patients diagnosed with GPA at a public tertiary care hospital between 2006 and 2017 was performed. Results A total of 19 patients were included in the present study, and 16 of them presented head and neck manifestations. Sinonasal symptoms were the most common, affecting 56% of the patients, followed by laryngotracheal (31.25%) and ear (25%) symptoms. In 7 patients, sinonasal symptoms were the first manifestation of the disease (43.75%). Four patients underwent surgery at some stage of the disease. Conclusions Head and neck involvement is common in GPA and may stand for the first or the onlymanifestation of the disease. The otolaryngologists play a central role in the diagnosis and long-term treatment of these patients, and they have to keep this pathology in mind when treating patients with ENT symptoms that do not respond as expected to the treatment.
  • Intervening in the Acute Phase of Postradiation Carotid Blowout Syndrome Original Researches

    Jong, Marrigje A. de; Candanedo, Carlos; Gross, Menachem; Cohen, José E.

    Resumo em Inglês:

    Abstract Introduction Acute carotid blowout syndrome (aCBS) is a severe complication of head and neck cancer (HNC). It can be defined as a rupture of the extracranial carotid arteries, or one of their branches, that causes life-threatening hemorrhage, and which nowadays can be treated with urgent endovascular intervention. Objective We retrospectively evaluate the endovascular management of aCBS and its outcome in years of survival. Methods Retrospectively, we describe our experience with endovascular control of aCBS in patients treated for HNC. We review the characteristics, pathology, endovascular treatment and morbidity and assess the gain in life years. Results Nine individuals were included in this study. Four patients had been previously diagnosed with laryngeal squamous cell carcinoma (SCC), one with paranasal SCC, one with nasopharyngeal carcinoma and three with oral or maxillary adenocarcinoma. All subjects underwent radiotherapy and surgical excision to different extents. Twelve endovascular procedures were performed for injuries to the internal carotid artery (n = 3; 25%), external carotid artery (n = 1; 7%) or one of their branches (n = 8; 67%). Deconstructive methods were used in nine procedures, and three procedures were mainly reconstructive with deployment of covered stents. Total control of bleeding was achieved in all individuals with no intraprocedural complications. Conclusion Endovascular therapy is an effective alternative for the management of exsanguinating CBS. In our series, this palliative therapy increased the overall patient survival by an estimated 9 months.

    Tawab, Hazem M. Abdel; Tabook, Salim M. Sloma

    Resumo em Inglês:

    Abstract Introduction Pseudocyst of the pinna is a rare condition that occurs when fluid accumulates in the intercartilagenous space of the auricle. The main goal when treating this condition is to keep acceptable cosmetic results with no recurrence rate. Objective To demonstrate the superior impact of incision and drainage of auricular pseudocysts with the insertion of a catheter drain and daily irrigation as the treatment of this condition. Methods A total of 42 patients with auricular pseudocysts were enrolled in the present study in the period between May 2011 and May 2017. All of the patients were treated with incision and drainage with compression. The average follow-up time reached ~ 6 months in all of the cases. Results All of the patients had satisfactory cosmetic results with no recurrence and no complications. Conclusion Among the different methods of surgical treatment of pseudocyst of the pinna, incision and drainage with daily irrigation is a significantly efficientmethod both for the eradication of auricular pseudocysts and for good cosmetic results.

    Zahara, Devira; Dewi, Rima Diana; Aboet, Askaroellah; Putranto, Fikri Mirza; Lubis, Netty Delvrita; Ashar, Taufik

    Resumo em Inglês:

    Abstract Introduction The cochlear anatomy varies in each individual, and that has an impact on decisions regarding the insertion of electrodes. The measurement of the cochlear size is the routine examination required to choose the proper cochlear implant (CI) electrodes. Objective To acquire normative data on the size of the cochlea (length, width, height, scala timpani [ST] height, cochlear duct length [CDL]) of CI candidates in Medan, Indonesia. Methods This descriptive study was conducted based on high-resolution computed tomography (HRCT) temporal bone data and on HRCT temporal data manipulated to reconstruct three-dimensional (3D) multiplanar images with OsiriX MD DICOM Viewer version 9.5.1 (Pixmeo SARL, Bernex, Geneva, Switzerland) viewer of 18 patients (36 ears) who were CI candidates in Medan, Indonesia, in order to determine cochlear length (A), cochlear width, cochlear height, ST height and CDL, calculated through a simple mathematical function. Results The average cochlear length (A) was 8.75 mm (standard deviation [SD] = 0.31 mm); the average cochlear width was 6.53 mm (SD = 0.35 mm); the average cochlear height was 3.26 mm (SD = 0.24 mm) and the average ST height at the basal cochlea was 1.00 mm (SD = 0.1mm); and 0.71 mm (SD = 0.1 mm) at the half turn of cochlea. The average total CDL was 32.45 mm (SD = 1.31 mm; range: 30.01-34.83 mm). Conclusion The cochlear size varies in each individual; therefore, the temporal bone measurement of CI candidates using HRCT is essential: for the selection of suitable implant electrodes; to minimize cochlear damages at the insertion of the electrode arrays; and to maximize the hearing improvements.
  • Bilateral Simultaneous Endoscopic Dacryocystorhinostomy: Outcome and Impact on the Quality of Life of the Patients Original Researches

    Herzallah, Islam R.; Marglani, Osama A.; Alherabi, Ameen Z.; Faraj, Nuha S.; Bukhari, Deemah H.

    Resumo em Inglês:

    Abstract Introduction Bilateral simultaneous endoscopic dacryocystorhinostomy (endo-DCR) has received little attention in the literature, thus many surgeons continue to address bilateral nasolacrimal duct obstruction at two stages, rather than in the same setting. Objective To evaluate the feasibility and the outcome of simultaneous bilateral Endo- DCR and its impact on the quality of life of the patients. Methods We have conducted a retrospective analysis of patients who underwent bilateral simultaneous endo-DCR between March 2013 and February 2017 at our tertiary care institution. The reviewed data included clinical presentation; operative details; success rate; pre and postoperative evaluation of the symptoms of the patients, using the Nasolacrimal Duct Obstruction Symptom Score Questionnaire; satisfaction of the patients, and improvement in the quality of life, assessed by the Glasgow Benefit Inventory (GBI) questionnaire. Results Out of 128 cases in which endo-DCRs were performed, 13 were bilateral (26 sides). Postoperative success was documented in 24 of the 26 sides (92.3%), with a mean follow-up duration of 16.2 months. The two failed sides were reported in the same case. The preoperative symptom score ranged between 12 and 80 (mean ± standard deviation [SD]: 38.23 ± 15.7). The postoperative symptom score was significantly lower (mean ± SD: 5.4 ± 12.9). The success rates in unilateral and bilateral cases were comparable, with no statistically significant difference. A notable improvement in the quality of life of the patients was also reported, with a mean GBI score of 81.38 ± 12.37. Conclusion Our results support that a simultaneous bilateral endo-DCR is a safe procedure that offers a high success rate, spares the patient from the stress of a second surgery, provides the patient with a bilateral resolution of the symptoms, and confers an immediate improvement in the quality of life of the patients.
  • Identification of Factors Related to Cases of Benign Paroxysmal Positional Vertigo Refractory to Canalicular Repositioning Maneuvers and Evaluation of the Need for Magnetic Resonance Imaging in their Management: Retrospective Analysis of a Series of 176 Cases Original Researches

    Carnevale, Claudio; Pérez, Guillermo Til; Tagle, Diego Arancibia; Barberán, Manuel Tomás; Echegaray, Pedro Sarría

    Resumo em Inglês:

    Abstract Introduction Benign paroxysmal positional vertigo (BPPV) is the most common form of peripheral vertigo, and, in most cases, it presents a favorable prognosis. The treatment is based on a series of specific canalicular repositioningmaneuvers that offer an efficacy close to 100%. Despite this, there are cases that are refractory to treatment, with the persistence of the vertigo symptoms. Objectives The objective of the present paper is to analyze the factors associated with an increased risk of refractory BPPV and the importance of nuclear magnetic resonance in the study of these patients. Methods We retrospectively reviewed the cases of 176 patients diagnosed with BPPV in our center.We divided them into two groups: responders and non-responders to the treatment, and analyzed the possible risk factors associated with a higher risk of refractory vertigo. Fischer exact test was used. Results We found 11 cases refractory to treatment; all of them underwent magnetic resonance imaging (MRI) with gadoliniumaccording to our protocol. Of these, four had an otoneurologic background or pathology, and two other patients presented a multicanal involvement. The difference between the two groups was statistically significant (p < 0.05). Conclusion Otoneurologic background and multicanal involvement were associated with a higher risk of refractory BPPV. When dealing with a BPPV with persistent symptomatology/nystagmus or with early relapse after an initial improvement, other entities that enter into the differential diagnosis must always be considered. We consider it essential to perform an MRI with gadolinium to rule out cases of BPPV that have a central cause.
  • Acoustic Voice Modifications in Individuals with Parkinson Disease Submitted to Deep Brain Stimulation Original Researches

    Romann, Aline Juliane; Beber, Bárbara Costa; Cielo, Carla Aparecida; Rieder, Carlos Roberto de Mello

    Resumo em Inglês:

    Abstract Introduction Subthalamic nucleus deep brain stimulation (STN-DBS) improvesmotor function in individuals with Parkinson disease (PD). The evidence about the effects of STN-DBS on the voice is still inconclusive. Objective To verify the effect of STN-DBS on the voice of Brazilian individuals with PD. Methods Sixteen participants were evaluated on the Unified Parkinson Disease Rating Scale-Part III, and by the measurement of the acoustic modifications in on and off conditions of stimulation. Results The motor symptoms showed significant improvement with STN-DBS on. Regarding the acoustic measures of the voice, only the maximum fundamental frequency (fhi) showed a statistical difference between on- and off-conditions, with reduction in off-condition. Conclusion Changes in computerized acoustic measures are more valuable when interpreted in conjunction with changes in other measures. The single finding in fhi suggests that DBS-STN increases vocal instability. The interpretation of this result should be done carefully, since it may not be of great value if other measures that also indicate instability are not significantly different.
  • Facial Plastic Surgery Faculty Turnover: Survey of Academic Facial Plastic Surgeons and Department Chairs Original Researches

    Kowalczyk, David Michael; Jordan, J Randall

    Resumo em Inglês:

    Abstract Introduction The turnover and inability to consistently retain academic facial plastic surgeons is an issue that many academic departments of otolaryngology face. In addition to the financial costs of staff turnover and gaps in patient care, insufficient exposure of residents to key surgical procedures is a significant problem for residency programs. Objective To identify themost important reasons that lead faculty members to leave an academic facial plastic surgery (FPS) practice as well as features that may be associated with retention of FPS faculty. Methods Members of the American Academy of Facial Plastic and Reconstructive Surgery (AAFPRS) and the Association of Academic Departments of Otolaryngology (AADO) were administered an anonymous, online survey. For both groups, we evaluated demographic factors, reasons for choosing academic careers, contributors to faculty turnover, as well as strategies for retention. The frequency of the responses was analyzed. Results A total of 11.3% (135/1,200) of facial plastic surgery faculty responded to the faculty survey, with 59.1% (68/115) of current, academic surgeons participating, and a total of 16.7% (20/120) of department chairs responded to the chairs’ survey. If a faculty member had left/was to leave, more control over practice was the most common reason between the two respondent groups. Of the fivemost important ways to increase faculty retention, more control over practice was the number one reason. Conclusion Chairs and facial plastic surgery faculty should strive to agree upon the amount of control over the academic practice to lead to higher retention, better patient care, and continued resident education.
  • Menière's Disease and Disorders of the Carbohydrate Metabolism Involving the Inner Ear Original Researches

    Albernaz, Pedro L. Mangabeira

    Resumo em Inglês:

    Abstract Introduction Menière’s disease was described in 1861, but there are still uncertainties regarding its pathophysiology and treatment. Endolymphatic hydrops is recognized as a fundamental pathological characteristic of the disease, as a result of an inadequate absorption of the endolymph. A milder type of endolymphatic hydrops results from an altered chemical composition of the endolymph, due to disorders of the carbohydrate metabolism. Objective To describe the association of both types of hydrops in patients with Menière disease. Methods This was a retrospective study of 98 patients with Menière’s disease, 62 of whom also presented disorders of the carbohydrate metabolism, and 5 patients with delayed endolymphatic hydrops, 2 of whom also presented disorders of the carbohydrate metabolism. Results The follow-up of these patients showed that the correction of the metabolic disorders may help in the clinical treatment of Menière’s disease and of delayed endolymphatic hydrops, but this does not happen in the more severe types of the diseases. Conclusion Patients with Menière’s disease may present simultaneous disorders of the carbohydratemetabolism, affecting the inner ear. The correction of these disorders helps the clinical treatment but does not preclude the progression of the more severe cases of Menière disease.
  • The Effectiveness of the Cold Therapy (cryotherapy) in the Management of Inflammatory Parameters after Removal of Mandibular Third Molars: A Meta-Analysis Systematic Review

    Fernandes, Ighor Andrade; Armond, Anna Catharina Vieira; Falci, Saulo Gabriel Moreira

    Resumo em Inglês:

    Abstract Introduction Cold therapy (cryotherapy) is a common procedure recommended by dental surgeons after surgical removal of thirdmolars, which is an invasive intervention that often deals with an expressive inflammatory response. Objective To investigate whether cryotherapy interferes with clinical outcomes such as pain, edema, and trismus in the postoperative period of mandibular third molar surgeries. Data Synthesis An electronic search was conducted in the OVID, PubMed, VHL, Science Direct, Cochrane Library, and Web of Science databases, through March 2018. The eligibility criteria included clinical trials that evaluated the effect of cryotherapy in at least one of the following variables: pain, swelling, and trismus. Two independent reviewers assessed the studies. The methodological quality of each article was analyzed. The search strategy resulted in 1,088 articles. Following the selection process, 11 studies were included in the systematic review and 4 of them in the meta-analysis. High risk of bias was found in most of the studies according to the Cochrane Handbook assessment. Patients receiving cryotherapy had less edema than patients in the control group at second day follow-up (mean difference [MD]: -0.94; 95%CI [-1.49; -0.39]). There were no statistically significant results when comparing trismus between experimental and control group (MD: 0.43; 95%CI [-0.34;1.20]). There were insufficient available data to support influences in postoperative pain. Conclusions Cryotherapy applied on thefirstday aftermandibular third molar removal can manage edema in the patients.Well-designed randomized clinical trials to test the efficacy of cryotherapy after surgical removal of third molars are needed to justify its indication.

    Rodrigues, Fernanda; Freire, Ana Paula; Uzeloto, Juliana; Xavier, Rafaella; Ito, Juliana; Rocha, Marceli; Calciolari, Renata; Ramos, Dionei; Ramos, Ercy

    Resumo em Inglês:

    Abstract Introduction The importance ofmucociliary clearance (MCC) for the respiratory system homeostasis is clear. Therefore, evaluating this defense mechanism is fundamental in scientific research and in the clinical practice of pulmonology and of associated areas. However, MCC evaluation has not been so usual due to the complexity ofmethods that use radiolabeled particles. Nevertheless, as an interesting alternative, there is the saccharin transit time (STT) test. This method is reproducible, simple to perform, noninvasive, does notdemand high costs, and has been widely used in studies of nasalMCC. Although the STT test is widely used, there is still lack of a detailed description of its realization. Objective The present literature review aims to provide basic information related to the STT test andto present the findings of the previous studies that usedthismethod, discussing variations in its execution, possible influences on the obtained results and limitations of the method, as well as to relate our experience with the use of STT in researches. Data Synthesis There are several factors that can alter the results obtained from STT tests, which would raise difficulties with proper interpretation and with the discussion of the results among different studies. Conclusions Saccharin transit time is awidely usedmethod for the evaluation of nasal MCC, and therefore, the standardization related to the previous and concurrent to test orientations, and also its execution, become essential to improve its accuracy, and allow comparisons among different studies.
  • Nasal Polyposis: More than a Chronic Inflammatory Disorder-A Disease of Mechanical Dysfunction- The São Paulo Position Update Manuscript

    Pezato, Rogerio; Voegels, Richard Louis; Pignatari, Shirley; Gregório, Luiz Carlos; Bezerra, Thiago Freire Pinto; Gregorio, Luciano; Balsalobre, Leonardo; Tepedino, Miguel Soares; Coronel, Nathália; Pinna, Fabio de Rezende; Mendes Neto, José; Oliveira, Pedro; Macoto, Eduardo; Stefanini, Renato; Figueiredo, Claudia; Haddad, Fernanda; Pilan, Renata; Soter, Ana Bezerra; Melo, Nelson Almeida; Candido, Danilo Almeida; Amaral, Jonatas do; Santos, Rodrigo de Paula; Zele, Thibaut Van; Fujita, Reginaldo; Dreyfuss, Juliana L.; Chamon, Wallace; Alencar, Adriano Mesquita; Perez-Novo, Claudina; Stamm, Aldo Cassol

    Resumo em Inglês:

    Abstract Introduction The importance of our study lies in the fact that we have demonstrated the occurrence ofmechanical dysfunction within polypoid tissues, which promotes the development of polyps in the nasal cavity. Objective To change the paradigm of nasal polyposis (NP). In this new conception, the chronic nasal inflammatory process that occurs in response to allergies, to pollution, to changes in the epithelial barrier, or to other factors is merely the trigger of the development of the disease in individuals with a genetic predisposition to an abnormal tissue remodeling process, which leads to a derangement of the mechanical properties of the nasal mucosa and, consequently, allows it to grow unchecked. Data Synthesis We propose a fundamentally new approach to intervening in the pathological process of NP, addressing biomechanical properties, fluid dynamics, and the concept of surface tension. Conclusion The incorporation of biomechanical knowledge into our understanding of NP provides a new perspective to help elucidate the physiology and the pathology of nasal polyps, and new avenues for the treatment and cure of NP.
