tympanic membrane perforation การใช้

Prolonged duration of otitis media is associated with ossicular complications and, together with persistent tympanic membrane perforation, contributes to the severity of the disease and hearing loss.
In 1995, Glasscock et al . published a 25-year single-centre review of over 900 patients who underwent stapedectomy and stapedotomy and found complications rates as follows : reparative granuloma 1.3 %, tympanic membrane perforation 1.0 %, total sensorineural hearing loss 0.6 %, partial sensorineural hearing loss 0.3 %, and vertigo 0.3 %.
