中文摘要
色素沉着绒毛结节性滑膜炎（PVNS）是一种罕见的局部侵袭性良性肿瘤，极少发生在颞下颌关节（TMJ）。本文报告1例罕见的累及咬肌间隙侵犯颞骨、颧骨及下颌升支的TMJ-PVNS。利用数字化技术确定肿瘤边界并重建正常关节窝，完整切除肿瘤后颞肌筋膜瓣转入钛网与髁突之间固定代替关节盘。术后随访30个月，患者面型对称，张口度43 mm，局部无复发，未出现脑脊液瘘、脑疝等并发症。
英文摘要
Pigmented villonodular synovitis (PVNS) is a rare locally aggressive benign tumor in the temporomandibular joint (TMJ). This paper presents a patient with TMJ-PVNS involving masseteric space, temporal bone, zygomatic process, and mandibular ramus. Digital technique was used to determine the boundary of the lesion and reconstruct the normal glenoid fossa. The temporalis myofascial flap was transplanted between titanium mesh and condyle to reconstruct the disk after the complete resection of the tumor. The patient’s facial profile is symmetrical, with a mouth ope-ning of 43 mm. No local recurrence and complications, such as cerebrospinal fluid fistula and encephaloceles, were detected during 30-month follow-up period.
