Summary |
Objective |
Study the results of surgical treatment of large vestibular schwannomas.
Material and methods |
Between January 1995 and December 2005, 87 stage III and IV unilateral vestibular schwannomas (Koos classification) were operated.
Results |
The approach used was for the most part translabyrinthine. Nine patients were operated in two phases. Tumor exeresis was total in 79% of the cases, nearly total in 17%, and subtotal in 3.6%. Good facial function was preserved in 63% of the patients. Mortality was zero. Tumor control after a mean follow-up of 45 months was 86%.
Conclusions |
Surgery for large vestibular schwannomas should have a 0% mortality rate and low morbidity. Otoneurosurgical collaboration, with a preference for the translabyrinthine approach, with surgery undertaken in several phases if need be, provides maximum safety and good functional results as well as an acceptable residual tumor rate.
