Temporomandibular joint (TMJ) disorder is a term that encompasses a number of overlapping conditions, such as closed lock. Closed lock of the TMJ is considered a consequence of a nonreducing deformed disc acting as an obstacle to the sliding condylar head that usually causes a decrease in the maximum mouth opening and acute pain. The management of the TMJ is still controversial. Thus, arthrocentesis of the TMJ is a valuable modification of the traditional method of arthroscopic lavage, which consists of washing the joint in order to remove chemical inflammatory mediators and intra-articular adhesions, changing intra-articular pressure. TMJ disorder has always presented as a therapeutic challenge to maxillofacial surgeons. Therefore, this paper aimed to describe a clinical report of a closed lock of the left TMJ in a 19-year-old female subject who was successfully treated by arthrocentesis procedure.
颞下颌关节（TMJ）紊乱是一个涵盖多种重叠病症的术语，比如闭口锁结。颞下颌关节的闭口锁结被认为是不可复位的变形盘作为髁突头部滑动障碍的结果，这通常会导致最大开口度减小和剧痛。颞下颌关节的治疗仍存在争议。因此，颞下颌关节穿刺术是传统关节镜灌洗方法的一种有价值的改良，传统关节镜灌洗包括冲洗关节以清除化学性炎症介质和关节内粘连，改变关节内压力。颞下颌关节紊乱一直是颌面外科医生面临的治疗挑战。因此，本文旨在描述一名19岁女性左侧颞下颌关节闭口锁结的临床报告，该患者通过穿刺术成功治愈。
