Abstract:
ObjectiveTo evaluate the value of microsurgery for acoustic neuromas.MethodsThe author performed a retrospective study of 63 consecutive patients after vestibular schwannomas (VSs) microsurgery with the retrosigoid approaches. The tumor was debulked firstly and dissected from surrounding neural and vascular structures by gripping the tumor capsule,and then drilled of the IAC.Intraoperative electrophysiological monitoring of facial nerve function during operation.Results Total tumor resection was achieved in 52 cases, subtotal resection was achieved in 11 cases. The anatomic preservation of facial nerve was achieved in 58 cases,the acoustic nerve was preserved anatomically in 29 cases.Fifty-eight cases received a follow-up, the mean follow-up time was 7.2 years. Two recurrent patients were found and there were no operative deaths. A long term facial nerve status:twenty-three cases were in grade Ⅰ, twenty-nine cases in grade Ⅱ ,five cases in grade Ⅲ , one cases in grade Ⅳ.Hearing level had an improvement in 9 cases and remained unchanged in 8 cases.ConclusionMicrosurgery treatment is the main choice of the treatment of VSs, could achieve better result in control of tumor and facial and acoustic nerve function restoration.
