[Sensorineural hearing loss caused by middle ear surgery].
It is well known that sensorineural hearing loss rarely occurs after middle ear surgery. Five cases of postoperative sensorineural hearing loss were reviewed. These operations amounted to 0.9% of all middle ear operations in which the first author was involved. The causes of hearing loss were believed to be labyrinthitis through the fistula in cholesteatoma case 1, and acoustic trauma from the bone-cutting burr in cases 2 and 3. In cases 4 and 5 postoperative sensorineural hearing loss occurred several months after stapes surgery and the causes of hearing loss were unknown. On the basis of the available literature discussion focused on management of labyrinthine fistula, the acoustic effect of the bone-cutting burr and the possibility of sensorineural hearing loss caused by stapes surgery.
