Valoración de la disfunción de trompa de Eustaquio mediante la aplicación de cuestionario ETDQ-7 y la relación con impedanciometría

Le résumé fourni par la source

Introduction: Eustachian Tube Dysfunction is a prevalent pathology in the ge­neral population, with a higher prevalence in children than in adults. Eustachian Tube Dysfunction results in inadequate ventilation of the middle ear and mastoid, which can lead to multiple symptoms and diseases such as hearing loss, recurrent serous otitis media, chronic otitis media, retraction and perforation of the tympanic membrane, and eventually the formation of cholesteatoma. Methods: A descripti­ve, cross-sectional observational study was conducted, in which 91 patients with symptoms of Eustachian tube dysfunction were evaluated. The Eustachian Tube Dysfunction Questionnaire (ETDQ-7) was administered, with a minimum score of 7 and a maximum score of 49. Results: In our study, 82.5% of the patients had a total ETDQ-7 score greater than 14.5. Tympanometry revealed a Type A curve in most patients in both ears, with 48.8% in the right ear and 61.5% in the left ear. Regarding the relationship between the ETDQ-7 and tympanometry findings, among patients with a score greater than 14.5, a Type A tympanometric curve was more frequently observed in the right ear (43.9% of cases), and in the left ear, 56.4% of those with an ETDQ-7 score above 14.5 presented a Type A curve on tympanometry.
