OBJECTIVE: To assess the degree to which condylectomy corrects the asymmetry and to determine the proportion of patients after condylectomy who were satisfied with the esthetic result and did not desire further corrective surgery.
METHODS: We conducted a retrospective analysis of medical records of patients who underwent condylectomy that was not followed by corrective orthognathic surgery for at least 1 year to determine the degree of correction of chin deviation and lip cant. Patient satisfaction from treatment or desire and undergo further corrective surgery was reported.
RESULTS: Chin deviation decreased after condylectomy from a mean of 4.8⁰ to a mean of 1.8⁰ (P < 0.001). Lip cant decreased after condylectomy from a mean of 3.5⁰ to a mean of 1.5⁰ (P < 0.001). Most patients (72%) were satisfied with the results and did not consider further corrective orthognathic surgery.
CONCLUSIONS: Proportional condylectomy could be a viable treatment to both arrest the condylar overgrowth and achieve some correction of the facial asymmetry.
目的:评估髁突切除术纠正不对称性的程度,并确定对美学结果满意且不希望进一步矫正手术的患者比例。
方法:我们对接受了至少1年未进行正颌矫正手术的髁突切除术的患者的病历进行了回顾性分析,以确定下巴偏斜和嘴唇倾斜的矫正程度。报告了患者对治疗或愿望的满意度,并接受了进一步的矫正手术。
结果:髁突切除术后的Chin偏差从平均4.8个降低到平均1.8个(P<0.001)。髁突切除术后嘴唇不能从平均3.5英里下降到平均1.5英里(P<0.001)。大多数患者(72%)对结果感到满意,没有考虑进一步的正颌矫正手术。
结论:比例性髁突切除术可能是一种可行的治疗方法,既可以阻止髁突过度生长,又可以矫正面部不对称。
