Abstract: Objective To investigate the clinlical features, diagnosis and treatment of facial nerve schwannoma in parotid region. Methods The clinical data of the 21 patients with facial nerve schwannoma in parotid region from 2005 to 2011 in our hospital were studied retrospectively. Results There were 18 cases have taken image examination among the 21 cases, however, only 1 case was diagnosed correctly preoperatively. The tumors in all 21 cases were resected surgically, 18 cases were totally removed，while the other 3 were subtotal removed. In these cases, 19 patients were no recurrence and 2 patients were lost follow-up. Conclusions Facial nerve schwannoma in parotid region is likely to be misdiagnosed. There is no preoperative diagnostic modality that can identify facial nerve schwannoma with certainty. However, the correct diagnosis of the disease depends on pathological examination. Surgical management is the major treatment of the disease. Resection of the tumor should be performed under careful protection of the function of the facial nerves in order to avoid severe complications postoperatively.
