Atopy and adenotonsillar hypertrophy in mouth breathers from a reference center.

UNLABELLED: Mouth breathers use the oral cavity as their principal breathing route. The main causes include: adenotonsillar hypertrophy and inflammatory diseases such as allergic rhinitis. OBJECTIVE: To look for atopy, the main allergens involved and to check for atopy as a comorbidity with the degree of hypertrophy of the tonsils and adenoids in mouth breathers. METHOD: A historical cohort study with cross-sectional review of 308 medical charts of patients treated at a mouth breather care center of a tertiary hospital in the period of 2008-2010. We collected data on the mouth breather's clinical history and we ran otolaryngological exams, flexible nasal endoscopy and skin prick test to aeroallergens. RESULTS: Of 308 patients, 36% were positive on allergy testing, with 95 % of atopic patients being positive for mites. Among all patients, 46% had adenoid hypertrophy; of these, 37% were atopic and 47% had tonsillar hypertrophy, and among these, 33% were atopic. CONCLUSION: We found no direct correlation between atopy and the degree of tonsils and adenoid hypertrophy observed among the mouth-breathing patients assessed. si.

Atopia e hipertrofia adenoamigdaliana em pacientes respiradores bucais em um centro de referencia / Atopy and adenotonsillar hypertrophy in mouth breathers from a reference center

O respirador bucal utiliza a cavidade oral como principal via durante a respiração. Dentre as principais causas, destacam-se: as hipertrofias adenoamigdalianas e as doenças inflamatórias como a rinite alérgica. OBJETIVO: Verificar a presença de atopia, os principais alérgenos envolvidos e verificar a coexistência de atopia com o grau de hipertrofia das tonsilas faríngeas e palatinas, em pacientes respiradores bucais. MÉTODO: Estudo de coorte histórico com corte transversal com revisão de 308 prontuários de pacientes acompanhados em um centro do respirador bucal de um hospital terciário, no período de 2008 a 2010. Foram coletados dados sobre a história clínica de respirador bucal e realizados exames clínico otorrinolaringológico, nasofibroscópico e teste cutâneo de leitura imediata aos aeroalérgenos. RESULTADOS: Dos 308 pacientes, 36% apresentaram positividade no teste alérgico, sendo que dos atópicos 95% foram positivos para ácaros. Do total de pacientes, 46% apresentaram hipertrofia adenoideana. Destes, 37% são atópicos e 47% apresentaram hipertrofia amigdaliana e, destes, 33% são atópicos. CONCLUSÃO: Nenhuma correlação direta entre atopia e o grau de aumento das tonsilas palatinas e faríngeas foi observada nos pacientes respiradores bucais avaliados. .
