[Failures after tympanoplasty].
Failures and pitfalls in chronic ear surgery have been studied. The material consists of a retrospective study of 616 cases of tympanoplasty. The results were mainly analysed into cases of iatrogenic cholesteatoma (23), labyrinthine fistulae (25) and disruption of ossicular chain (46). The incidence of fistula into the semi-circular canal is high with cholesteatoma, and careful removal of the matrix is recommended to prevent sensorineural hearing loss. Disarticulation of the incudo-stapedial joint is performed to eradicate attic cholesteatoma and protect the cochlea. However, this procedure gives a risk of damage to the inner ear. The frequency and nature of sensorineural losses following chronic ear surgery have been discussed. Surgical precautions are advocated to prevent inner ear damage or other iatrogenic complications.
