Wound closure after acoustic neuroma surgery.

Cerebrospinal fluid leakage from the wound or middle ear cavity remains a common cause of morbidity after acoustic neuroma surgery, regardless of the operative route employed. An incidence of around 15% is reported in most large series. The authors describe a method of wound closure which is applicable to both translabyrinthine and retrosigmoid tumour excision. Adoption of this technique in 188 consecutive patients has reduced the incidence of this complication in our unit from 13% to 1.6%.
