Condylar hyperplasia is an overdevelopment of the condyle, which may manifest unilaterally or bilaterally. This pathological condition can lead to facial asymmetry, malocclusion, and dysfunction of the temporomandibular joint. The etiology and pathogenesis of condylar hyperplasia remain uncertain, but it has been suggested that its etiology may be associated with hormonal factors, trauma, and hereditary hypervascularity, affecting both genders. The diagnosis is made by clinical examination, and radiological imaging, and additionally, bone scintigraphy, is a fundamental resource for determining whether the affected condyle shows active growth. Patients with active condylar hyperplasia management have better results when they are subjected to the high condylectomy procedure. The authors report a case in a 20-year-old female subject with unilateral active condylar hyperplasia who was treated by high condylectomy. The patient has been followed up for 4 years without signs of recurrence and with good functional stability of the occlusion.
髁突增生是髁突的过度发育，可单侧或双侧出现。这种病理状况可导致面部不对称、咬合不正和颞下颌关节功能障碍。髁突增生的病因和发病机制尚不确定，但有人认为其病因可能与激素因素、创伤和遗传性血管增生有关，男女均可受累。诊断通过临床检查和放射影像学进行，此外，骨闪烁显像对于确定受累髁突是否显示活跃生长是一项重要的检查手段。活动性髁突增生患者接受高位髁突切除术时治疗效果更佳。作者报告了一例20岁女性单侧活动性髁突增生患者，经高位髁突切除术治疗。该患者已随访4年，无复发迹象，咬合功能稳定性良好。
