Benign tumors of the nerve sheath are of 2 types: schwannoma and neurofibroma. Neurofibromas are most commonly found with neurofibromatosis type 1 and characterized by incorporation of the nerve fibers within their matrix. Both benign and malignant tumors can affect the facial nerve. These tumors can be intrinsic or extrinsic; in other words, it can originate from the facial nerve itself or from a contiguous structure or a metastatic disease. Actually, extrinsic tumors are far more common than intrinsic tumors. Intraparotid location of benign tumors of the facial nerve sheath is considered a rare event compared with intratemporal location.
神经鞘瘤和神经纤维瘤。神经纤维瘤最常与1型神经纤维瘤病相关，其特征是神经纤维融入其基质中。良性和恶性肿瘤均可累及面神经。这些肿瘤可以是原发性的或继发性的；换句话说，它可以起源于面神经本身，也可以起源于相邻结构或转移性疾病。实际上，继发性肿瘤比原发性肿瘤更为常见。与颞内位置相比，面神经鞘良性肿瘤位于腮腺内被认为是罕见情况。
