Abstract：Objective To explore the factors influencing the prognosis of facial nerve function after surgical resection of acoustic neuroma.Methods Clinical data of 164 unilateral acoustic neuroma patients with both total tumor removal and facial nerve anatomic preservation were analyzed retrospectively.The facial function 8 days and 1 year after surgery was assessed by House-Brackmann (HB) scale,and Logistic regression was used to select the risk factors influencing the facial nerve function after surgery.Results Univariate logistic regression showed that medium-large tumors,cystic tumors,anterior-superior tumors and severe adhesion with facial nerve were associated with facial nerve injury (P ＜ 0.01);and there was no correlation between the clinical factors and the injury of facial nerve function 1 year after operation (P ＞ 0.05).Multivariate logistic regression analysis showed that the large tumor and severe adhesion with facial nerve were the independent risk factors for facial nerve function 8 days after operation (P ＜ 0.05).The facial nerve function was good in 119 patients and impaired in 45 on the day 8 after operation,while good in 140 and impaired in 24 in 1 year after operation.Conclusion The damage degree of facial nerve function 8 days after surgery cannot predict the damage severity of postoperative long-term facial nerve function.
