Schwannomas of the middle ear may originate from the nerves of the middle ear cavity or by extensions from neighboring structures. We present a case of a 51-year-old female patient with primary middle ear schwannoma believed to arise from Jacobson's nerve. The tumor was easily divided from the facial nerve and the chorda tympani nerve. Erosion of the promontory was noted, and the jugular foramen and posterior wall of the ear canal were preserved without destruction. The mass was successfully removed by a canal down mastoidectomy procedure, while preserving the hearing and facial nerve functions of the patient. To our knowledge, this is only the second reported case of a patient with Jacobson's nerve schwannoma.
中耳神经鞘瘤可能起源于中耳腔的神经或由邻近结构蔓延而来。我们报告一例51岁女性原发性中耳神经鞘瘤患者，该肿瘤据信起源于鼓室神经。肿瘤很容易与面神经和鼓索神经分离。可见岬部骨质侵蚀，颈静脉孔和外耳道后壁未受破坏得以保留。通过耳道径路乳突切除术成功切除肿物，同时保留了患者的听力和面神经功能。据我们所知，这是第二例报告的鼓室神经神经鞘瘤患者。
