: Bifid mandibular condyle (BMC) is a rare etiology of temporomandibular joint (TMJ) disorders characterized by a duplication of the head of the mandibular condyle.: The authors report the case of a 20-year-old patient complaining of a painful and clicking TMJ and mandibular hypomobility, which had been progressing for several months. Radiological investigations (dental panoramic radiograph and X-ray CT scan) revealed right and left abnormalities of the TMJ due to bilateral BMC requiring surgical management.: Despite a prevalence of 0.31% to 1.82% and the controversies surrounding its pathophysiology, maxillofacial surgeons should be aware of BMC to avoid misdiagnosis related to the clinical presentation (pain, clicking, hypomobility, or ankylosis) and provide adequate management.
: 双侧下颌骨髁(BMC)是一种罕见的颞下颌关节(TMJ)疾病病因,其特征是下颌骨髁的头部重复。:作者报告了一例 20 岁患者的病例,该患者抱怨 TMJ 疼痛和弹响,以及下颌运动受限,这种情况已经持续了几个月。影像学检查(口腔全景片和 X 射线 CT 扫描)显示双侧 BMC 导致右侧和左侧 TMJ 异常,需要手术治疗。:尽管 BMC 的患病率为 0.31%至 1.82%,其病理生理学也存在争议,但颌面外科医生应该了解 BMC,以避免因临床表现(疼痛、弹响、运动受限或强直)而导致的误诊,并提供适当的治疗。
