颞下颌关节强直可由创伤、感染、退行性变及间隙缺损导致。其中以局部感染多见,而全身感染则罕见。本文报道1例因全身远处感染导致双侧颞下颌关节强直的患者,该35岁女性患者因开口困难近20年就诊,并于20年前出现包括颞下颌关节区的全身多处脓肿,CT显示髁突与颞骨融合。采用双侧颞下颌关节截除术及人工关节置换术治疗,术后3个月开口度达2.5 cm,患者获得了满意的进食及语言功能。
Temporomandibular joint stiffness can be caused by trauma, infection, degenerative changes, and gap defects. Among them, local infection is more common, while systemic infection is rare. This article reports a case of distal temporomandibular joint ankylosis due to systemic remote infection in patients, the 35-year-old female patients due to difficult to open the mouth for nearly 20 years of treatment, and 20 years ago, including the temporomandibular joint area of multiple abscesses, CT Condyle and temporal bone fusion. Bilateral temporomandibular joint surgery and artificial joint replacement surgery were performed. The opening degree reached 2.5 cm at 3 months after operation. The patients achieved satisfactory eating and speech function.
