摘　　要：软骨黏液样纤维瘤(chondromyxoid fibroma,CMF)是一种罕见的良性骨肿瘤,目前为止仅1例报道原发于颞下颌关节(temporomandibular joint,TMJ)的病例。本文报告1例罕见的累及翼腭窝且侵犯颅底的TMJ-CMF。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,将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1年,患者面型对称,开口度45 mm,局部无复发,未出现脑脊液瘘、脑疝等术后并发症。Chondromyxoid fibroma(CMF) is an exceedingly rare benign bone tumor,to the authors' knowledge,only one case primarily occurred in temporomandibular joint(TMJ) has been reported in the literature.This paper presented a pa-tient with TMJ-CMF involving pterygopalatine space,and the skull base thereof.Digital technique was used to determine the boundary of the lesion and reconstruct the normal glenoid fossa,the temporalis myofascial flap was transplanted be-tween titanium mesh and condyle so as to reconstruct the disk after complete resection of the tumor.The patient's facial profile is symmetrical,with a mouth opening of 45 mm.There was no local recurrence,no complications such as cere-brospinal fluid fistula and cerebral hernia during 1-year follow-up period.
