Abstract:Abstract:ObjectiveTo investigate surgical effect of sidetoend hypoglossal to facial nerve anastomosis after cerebellopontine angle tumor resection.MethodsA total of 6 patients underwent tumor resection in cerebellopontine angle received sidetoend hypoglossal to facial nerve anastomosis. All patients were followed up every three months, and their grade of HouseBrackmann (HB) and tongue function were evaluated.ResultsOne year after surgery, 2 patients achieved HB grade III,3 grade IV, and one grade V. Four patients achieved good facial tone at 6 months after reconstructive surgery, and the rest achieved at 9 months and one year respectively. Significant tongue atrophy, impaired tongue mobility, speech or swallow dysfunction occurred in none.ConclusionsSidetoend hypoglossal to facial nerve anastomosis is an efficient way to reanimate facial paralysis after cerebellopontine angle tumor resection. Intraoperative nerve monitor may be beneficial to the protection of tongue function.
