颌骨中心性神经鞘瘤较少见,文献中已报告的病例中下颌骨占27例,上颌骨仅1例。神经鞘瘤称雪旺氏瘤,因来源于雪旺氏细胞,文献中命名混淆不清,但根据肿瘤成份有不同的分类,在鉴别诊断上仍有相当的价值。神经鞘瘤好发于头颈部,发生于口腔内少见,发生于颌骨中心性者更少见,Gupta等人收集了303例神经鞘瘤,其中44.8％发生于头颈部,9％发生于口腔,Bruce也曾报告2例系发生于口腔,130例发生于喉部,Momot报告 Central schwannomas of the jaws are rare, and 27 cases of mandibular and only 1 case of maxilla have been reported in the literature. Schwannoma is known as Schwannoma due to Schwann’s cell origin. The name in the literature is confusing. However, depending on the different classification of tumor components, there is still considerable value in differential diagnosis. Schwannomas occur predominantly in the head and neck, occur rarely in the mouth, and occur less frequently in the central jaw. Gupta et al. collected 303 schwannomas, of which 44.8% occurred in the head and neck and 9% occurred in Oral, Bruce also reported 2 cases occurred in the mouth, 130 cases occurred in the throat, Momot report
