Facial nerve schwannomas (FNS) are encapsulated benign tumors arising from Schwann cells of seventh cranial nerve. Most of the facial nerve schwannomas are localized in intratemporal region; only 9% of cases involve a portion of the extratemporal segment. Preoperative diagnosis is often unclear; diagnosis is often made intraoperatively. Management of intraparotid FNS is troublesome because of the facial nerve paralysis. In this report we presented a case of intraparotid schwannoma in a 55-year-old male patient complaining of a painless mass without peripheral facial nerve palsy in left parotid gland. Clinical features, preoperative and intraoperative diagnosis, and difficulties during management are discussed with the review of the literature.
面神经鞘瘤（FNS）是起源于第七颅神经施万细胞的包膜性良性肿瘤。大多数面神经鞘瘤位于颞骨内区域；仅9%的病例累及颞骨外段的一部分。术前诊断往往不明确；诊断通常在术中做出。腮腺内FNS的治疗因面神经麻痹而棘手。在本报告中，我们介绍了一例55岁男性腮腺内鞘瘤患者，该患者主诉左侧腮腺有无痛性肿块，无周围性面神经麻痹。结合文献复习，讨论了其临床特征、术前和术中诊断以及治疗过程中的困难。
