Temporomandibular joint (TMJ) ankylosis during early childhood always produces alteration of the mandibular growth with facial asymmetry, chin deviation, and malocclusion. The younger the ankylosis happens, the more severe the facial deformity presents. When TMJ ankylosis occurs in infancy, there might be a delay in diagnosis and treatment. In this article, we describe a case of TMJ ankylosis in a 10-month-old boy. The etiology was indistinct. Surgical plan including modified gap arthroplasty, costochondral graft (CCG), temporalis fascial flap, was preformed to this patient. The joint and the mandibular ramus were restored. No severe complication occurred. There was no recurrence of ankylosis and further developing of mandibular asymmetry during 2-year follow-up period.
儿童早期颞下颌关节（TMJ）强直总会导致下颌生长改变，出现面部不对称、颏部偏斜和错牙合畸形。强直发生时年龄越小，面部畸形越严重。当TMJ强直发生于婴儿期时，可能会出现诊断和治疗延迟。在本文中，我们描述了一名10个月大男孩的TMJ强直病例。病因不明。对该患者实施了包括改良间隙关节成形术、肋软骨移植（CCG）、颞肌筋膜瓣在内的手术方案。关节和下颌升支得以恢复。未发生严重并发症。在2年的随访期内，强直未复发，下颌不对称也未进一步发展。
