Sensorineural hearing loss in tympanoplasty

ABSTRACT

A series of 236 consecutive tympanoplasty type one procedures performed from 1983 to 1985 at Riyadh Central Hospital was reviewed. Of these, there were ten cases of sensorineural hearing loss attributable to the surgical procedure. Loss of bone conduction by more than 10 dB in frequencies 0.5 kH[z] was considered significant. The main source of the labyrinthine damage was considered to be hydraulic trauma caused by excessive stapedial movement during removal of the disease process. Immediate postoperative infection of the ear was a second source of damage. The current views on the treatment of post-tympano plasty sensorineural hearing loss will be discussed
