Abstract：
Giant cell tumors of bone (GCTBs) are benign osteolytic neoplasms that can be treated with either gross-total resection or subtotal resection with adjuvant radiotherapy. For the rare GCTB of the temporal bone, close proximity to critical structures can produce functional deficits and make gross-total resection difficult to achieve without significant morbidity. We present the case of a 28-year-old woman with progressive facial paresis, otalgia, neck pain, imbalance, and subjective hearing loss. She was found to have a facial nerve mass centered at the geniculate ganglion extending into the labyrinthine segment and vestibule. We achieved gross-total resection with preserved facial nerve function as the tumor did not originate from the facial nerve and could be dissected free from the nerve. Final pathology was consistent with GCTB.
摘要：
骨巨细胞瘤（GCTB）是良性溶骨性肿瘤，可以通过全切除或辅助放射治疗次全切除进行治疗。对于罕见的颞骨GCTB，靠近关键结构会产生功能缺陷，并且在没有明显发病率的情况下难以实现全切除。我们介绍了一名28岁女性进行性面部麻痹的病例，耳痛,颈部疼痛,不平衡,主观听力损失。发现她的面神经团以膝状神经节为中心，延伸到迷宫段和前庭。由于肿瘤并非源自面神经，可以从神经中解剖，因此我们实现了保留面神经功能的全切。最终病理符合GCTB。
