腮腺内面神经鞘瘤21例临床分析

目的　探讨腮腺内面神经鞘瘤的临床特点、诊断及治疗要点，最大程度保留面神经连续性。方法　回顾分析中国医科大学附属口腔医院2005~2011年收治的21例腮腺内面神经鞘瘤患者的临床特点、影像学表现、诊断及治疗。结果　21例患者中术前行影像学检查共18例，确诊为神经鞘瘤者仅1例。21例患者均行手术切除肿瘤并经病理明确诊断，其中18例患者瘤体完整切除，3例患者瘤体部分切除。共19例患者术后随访，随访期为1~5年，所有随访病例未发现肿瘤复发。结论　腮腺内面神经鞘瘤早期诊断较困难，影像学检查虽有辅助价值，但确诊仍有赖于病理诊断，该病以手术治疗为主，术中应尽量保护面神经，避免并发症的发生。

Clinical analysis of facial nerve schwannoma in parotid region

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.
