| Abstract: Objectives: To study whether retracted tympanic membrane is a cause or a result of otomycosis. Patients and Methods: The study involved 70 patients (100 ears) suffering from otomycosis, all of them were evaluated by clinical examination and sometime by audiological investigations to evaluate the state of the tympanic membrane (retracted or normal in position). Results: The study revealed that 50% of ears had a retracted tympanic membrane due to negative middle ear pressure secondary to Eustachian tube obstruction. In 20% of ears, the tympanic membrane was just pushed inside by the mass of fungal infection and in 30% the tympanic membrane was normal in position. Conclusion: Retracted tympanic membrane caused by negative middle ear pressure is an important predisposing factor which needs correction to have complete cure and to prevent recurrence of otomycosis. The study revealed that negative middle ear pressure affect the normal epithelial migration of the tympanic membrane and leads to accumulation of debris in the external auditory canal and increases the risk of otitis externa. Key words: Otomycosis, fungal otitis externa, retracted tympanic membrane. | ||
