INTRODUCTION: At the initial consultation, the speech-language pathologist and audiologist may consider possible diagnostic hypotheses based on the child's history and the parents' complaint. AIM:To investigate the association of hearing complaints with the findings obtained in the conventional audiologic assessment in children with cleft lip and palate. Retrospective study. METHODS: We analyzed medical charts of 1000 patients with cleft lip and palate who underwent surgical repair between 1988 and 1995 at a mean age of 6 years 8 months. We excluded charts with records of inconsistent audiological responses and charts with missing data for any of the audiologic evaluations considered. Thus, the sample consisted of 393 records. RESULTS: Two hundred thirty-nine patients presented hearing loss in one or both ears, but only 3.8% reported hearing complaints. The most frequent were otorrhea followed by otalgia. There was no statistical significance between the complaint and gender (p = 0.26) nor between the complaint and hearing loss (p = 0.83). CONCLUSION: This study showed no association between the hearing complaint and the conventional audiologic assessment.

Cleft lip and palate is a craniofacial anomaly caused by failure in the fusion of embryonic facial processes (1). It is the most common malformation, occurring in approximately 1 per 500-700 births and, this ratio vary considerably across ethnic grouping. This congenital deformity results in esthetic and functional alterations, depending on the affected structures.
Otological and hearing problems have a high prevalence in the population with cleft lip and palate compared with the unaffected population, because this malformation affects important structures in the tympanic ossicular chain, thereby predisposing to otitis media with consequent hearing loss. Therefore, special attention should be given to this aspect (2-4).
During the initial consultation, the speechlanguage pathologist and audiologist may consider possible diagnostic hypotheses on the basis of the child's history and the parents' complaint (5).
Earlier diagnosis of auditory difficulties in children results in better intervention and support in cognitive and social development. Considering the importance of early diagnosis of hearing impairment and the knowledge of language development, the situation with regards to identification and early diagnosis requires clarification. This may facilitate introduction and performance of actions that prevent delayed language development in children with hearing difficulties (6).
Therefore, the purpose of this study was to verify the association of auditory complaints with the findings of the conventional audiologic assessment in children with cleft lip and palate who were treated at a specialized hospital in a city located in the state of São Paulo.
The present study was approved by the Ethics Committee of Bauru School of Dentistry (FOB/USP), process number 049/2008. This retrospective study utilized 1000 randomly selected charts of patients with cleft lip and palate who underwent surgical repair between 1988 and 1995. The survey was conducted in 2009 in a hospital of interdisciplinary treatment.
We verified data regarding gender, age, speech, language, and audiologic history, in addition to data concerning conventional audiologic assessment (pure-tone audiometry).
The patient's audiologic history was verified in the interview, with an emphasis on hearing complaints. In the audiologic assessments we verified the presence or absence and the type of hearing loss. The audiologic assessments were performed with a Midimate 622 audiometer.
We excluded medical charts with records of inconsistent audiologic responses and charts with missing data for any of the audiologic evaluations considered. Therefore, we included the records of 393 patients in the statistical analysis.
Of the 393 charts studied, 262 (66.6%) belonged to boys and 131 (33.3%) belonged to girls aged between 4 years and 10 years 11 months.
The Qui-square test was used for the statistical analysis. The minimum level of significance was set at 5% (p < 0.05). Categorical variables were arranged in tables.
Of the 393 patients, 239 presented hearing loss in one or both ears, which was conductive, mixed, or sensorineural. The conductive hearing loss was predominant (Table 1).
Only 15 patients reported auditory complaints in the speech, language, and audiologic history (3.8%); otorrhea (n = 10) was the most frequent finding in these patients followed by otalgia (n = 9). In contrast, 378 (96.18%) did not report complaints regarding hearing (Table 2).
Among the 15 individuals who reported auditory complaints, there were 8 boys and 7 girls, and there was no correlation between the complaint and the gender (p = 0.26). Most patients with auditory complaints in the interview presented with hearing loss in at least one ear (p < 0.001). The results of the audiologic assessment of these patients are reported in Table 3.
Not all patients with hearing loss had complaints related to hearing. We analyzed the 378 (96.18%) charts of children with no complaints about hearing and considered the presence or absence and the type of hearing loss in the audiologic assessment (Table 4).
We did not find a significant association (p = 0.83) between the presence of hearing complaints and hearing loss in all the patients (n = 393). Considering each ear (right and left) of all the 393 patients (n = 786), the otoscopy findings were normal in 755 ears (96.06%) and abnormal in only 31(3.94%).
Hearing disorders in children should be identified and treated early, because even mild hearing loss can influence the way sounds are processed and affect language development; consequences include speech production with phonetic errors, learning difficulties, poor reading comprehension, and unsatisfactory academic performance, as well as inadequate social skills (7, 8).
It is noteworthy that hearing impairment in children with cleft lip and palate is a secondary feature, and for this reason, hearing complaints are often not reported by parents.
However, in cases of mild hearing loss, symptoms may go unnoticed by the individual and/or family (9), or the individual may present asymptomatic auditory alterations, which highlights the importance of early audiologic diagnosis to enable appropriate treatment.
In a study conducted at the SpeechLanguage Pathology and Audiology Department of the Baleia Hospital in Belo Horizonte, 85% of the children aged between 3 and 12 years with surgically repaired cleft palate did not present auditory complaints (10). This is corroborated by the data obtained in this study, in which 96% had no auditory complaints.
Regarding the types of auditory complaint, a study (11) conducted with 150 medical records showed that 83% of the sample had some type of hearing complaint, the most frequent being unilateral or bilateral hearing loss (64%). Otitis and otorrhea (current or previous) were more prevalent in the presurgical groups undergoing tympanoplasty and tympanomastoidectomy. The least reported complaint was otalgia, which was present in only 37% of the sample. Because serous otitis media does not cause pain, it is a "silent" pathology, going unnoticed by the individual or family (12).
However, the literature is generally limited to the presence or absence of hearing complaints and does not note the type of complaint most commonly found in individuals with cleft lip and palate (9).
In this study, the main complaints reported by parents of children with hearing complaints were related to the conductive system, because the most frequent complaints reported in the audiologic interview were otitis and otorrhea.
We observed that even in cases where there was no complaint of hearing loss or hearing difficulties, hearing loss was detected. From the analysis of the 378 records of children with no history of auditory complaints, 108 (28.57%) had some type of hearing loss in the audiologic assessment, the majority (94%) being conductive hearing loss in at least one ear. Hearing loss is unnoticeable until its effects translate into oral language impairment, and rehabilitation at this stage may be less effective. Thus, early detection of this disorder is critical (13).
Parents may fail to identify hearing loss because the presence of otitis media with effusion (OME) in children is usually inconspicuous and does not cause pain (14). Depending on age, complaints may not be specific and include fever, irritability, moderate or intense crying, anorexia, diarrhea, and vomiting (15).
Considering that our study sample represents school-aged children, recognition of hearing difficulties and early diagnosis of the severity of the hearing loss, together with preventative actions for consequences related to auditory and communication skills, are important factors in the academic development of a student with hearing loss (16).
Another study that sought to determine the frequency of hearing complaints in children with learning difficulties pointed out that complaints of tinnitus and discomfort to sounds were the most frequent in this group (17). Our study found complaints of tinnitus in 33.33% of the children with hearing complaints, which might suggest, in addition to possible hearing alterations, other impairments of metabolic or circulatory origin.
We consider the low presence of alterations on otoscopy (3.94%) due to use of conventional otoscopy. Studies (18, 19) support the use of pneumatic otoscopy as a diagnostic tool, which is suitable, inexpensive, and can predict the presence of fluid (effusion) in the middle ear. The position and mobility of the eardrum are considered the most important diagnostic indicators.
The results of this study suggest the use of questionnaires and checklists, with greater specificity and sensitivity for otologic and auditory problems, in the population with cleft lip and palate.
Parents require fundamental guidelines so they can recognize even mild hearing difficulties in their children and, therefore, minimize the disorders that may arise as a result of sensory deprivation.
The present study showed no association between the auditory complaints and the conventional audiologic assessment.
