Assessment of eustachian tube functions in patients with ear drum perforation

Tubal malfunction is the most important factor in the development and persistence of otitis media. When the eustachian tube malfunction persists, the most carefully performed surgery will fail because the initiating pathogenetic factors of eustachian tube function and middle ear ventilation are still present. Measurement of the eustachian tube function is therefore an important part of the medical and surgical evaluation of the middle ear disease.
