LEMOS, Catiane Maçaira de; WILHELMSEN, Niels Sales Willo; MION, Olavo de Godoy  and  MELLO JUNIOR, João Ferreira de. Functional alterations of the stomatognathic system in pacients with allergic rhinitis: case-control study. Rev. Bras. Otorrinolaringol. [online]. 2009, vol.75, n.2, pp.268-274. ISSN 0034-7299.

Mouth breathing can cause structural and functional alterations to the stomatognathic system. AIM: the aim of this investigation was to study breathing, chewing, swallowing and speaking alterations present in patients with allergic rhinitis and associate it to rhinitis symptom intensity. MATERIALS AND METHODS: 170 patients between the ages of 6 and 55 years were prospectively evaluated in this study, all of them underwent both otorhinolaryngological and speech evaluation. Data on breathing, chewing, swallowing and speaking was gathered, as well as data from the medical evaluation. The data was compared and statistically analyzed. RESULTS: the difference in signs and symptoms' score between GR and GC was significant. We noticed a significant difference between GR and GC in breathing, chewing and swallowing. We observed a significant association between the score of nasal obstruction and the intensity of breathing and chewing alterations. CONCLUSION: patients with allergic rhinitis have functional alterations in their stomatognathic system and an increase in nasal obstruction scores can be considered as a indication of such alterations.

Keywords : deglutition; mastication; nasal obstruction; mouth breathing; stomatognathic system; articulation disorders.
