INTRODUCTION
Ancient schwannoma of infratemporal fossa arising from the trigeminal nerve is very rare in clinical practice.
CASE REPORT
A 65-year old male presented to the outpatient department with a progressive swelling over the left parotid for 5 years and pain during chewing for 6 months which was diagnosed as benign spindle cell tumour on cytology. The tumor was excised with a combined transparotid and transmandibular cervical approach and the final pathology was confirmed to an Ancient Schwannoma.
CONCLUSION
A giant infratemporal fossa Schwannoma extending to the parapharyngeal space masquerading as a parotid swelling is very unusual. Transparotid transmandibular excision of the infratemporal fossa tumor is an effective approach ensuring complete removal of the tumor with minimal postoperative complications and acceptable cosmoses.
引言
起源于三叉神经的颞下窝古老型神经鞘瘤在临床实践中极为罕见。
病例报告
一名65岁男性因左侧腮腺进行性肿胀5年、咀嚼时疼痛6个月就诊于门诊，细胞学检查诊断为良性梭形细胞瘤。采用经腮腺和经下颌颈联合入路切除肿瘤，最终病理确诊为古老型神经鞘瘤。
结论
巨大的颞下窝神经鞘瘤延伸至咽旁间隙并伪装成腮腺肿胀非常罕见。经腮腺经下颌切除颞下窝肿瘤是一种有效的方法，可确保肿瘤完全切除，术后并发症最少且美容效果可接受。
