Facial palsy was the first presentation in 10 cases, with repetitive facial palsy and vertigo in 1 case; 6 cases (54.5%) were insidious and 5 (45.5%) were sudden in terms of onset. Ear pain around the onset of facial palsy was found in four cases (36.4%). The tumor involved more than one segment in six cases. Among the non-grafted cases one patient with grade V facial nerve function recovered to grade III and another patient with grade VI facial nerve function recovered to grade IV, whereas only one case with grade VI recovered to grade IV among the grafted cases.

Our findings demonstrated that the optimized method could improve the positive detection rate of AMR and accuracy of decompression effect prediction. The evaluation for the decompression effect by optimized intraoperative monitoring can increase the immediate remission rate and reduce the delayed recovery rate.
