The authors report the unusual presentation of an intracranial extension of synovial chondromatosis of the temporomandibular joint. The patient presented with a peripheral facial nerve paralysis and anacusis. Computerized tomography revealed the lesion, but fine-needle biopsy was inconclusive. Craniotomy with removal of the tumor was performed, and pathological studies confirmed the diagnosis. The facial nerve dysfunction was thought to be secondary to direct neural compression.
作者报告了颞下颌关节滑膜软骨瘤病颅内扩展的罕见表现。该患者表现为周围性面神经麻痹和失聪。计算机断层扫描发现了病变，但细针活检结果不明确。进行了开颅肿瘤切除术，病理研究证实了诊断。面神经功能障碍被认为是直接神经受压所致。
