摘要
关节旁黏液瘤是一种来源于腱鞘、韧带等关节旁组织的良性软组织肿瘤,目前未见发生于颞下颌关节(temporomandibular joint,TMJ)旁的报道。本文报告1例罕见的TMJ旁黏液瘤,其体积巨大并累及髁突前内侧的颞下间隙。采用经髁突及盘前附着进路摘除肿瘤。术后随访2.5 a,患者无不适主诉,无颌面部畸形和开口受限,影像学检查显示肿瘤未复发。经髁突及盘前附着进路不仅保存了正常TMJ的结构和功能,还利于完整摘除肿瘤,防止复发。
Juxta-articular myxoma is a benign tumor originating from the soft tissue related to the joints, such as the tendon sheath and ligament. According to our knowledge, there was no report on juxta-articular myxoma located in the temporomandibular joint（TMJ） before. In this paper, a rare juxta-articular myxoma occurring in the TMJ, anteromedially extending to the infratemporal fossa（ITF） was reported. A novel surgical method using transcondylar approach assisted with the anterior release of the disc for this unique case was used for excision of the tumor. At 30-month of follow-up, the patient recovered with neither cosmetic problems nor limitation of mouth opening. No sign of local recurrence was found on imaging examinations. The results suggested that the novel approach could not only preserve the structure and function of the TMJ, but also help complete exposure and excision of the tumor.
