目的:评价下颌支后缘垂直骨切开术用于治疗髁突骨软骨瘤的临床效果。方法:对我院2004—2009年间9例应用髁突切除术及带蒂下颌支后缘上移重建髁突治疗髁突骨软骨瘤的患者进行随访,并通过影像学、咬合关系及颞下颌关节功能进行综合评估。结果:经过至少8个月的随访,所有患者髁突重建后的咬合关系、面形及关节功能均恢复良好。影像学检查显示,下颌支后缘上端位于关节窝内,随着时间的推移,逐渐改建呈光滑的扁球形。结论:下颌支后缘垂直骨切开带蒂上移,是重建因骨软骨瘤切除所导致的髁突缺损的一种较为理想的方法。 Objective: To evaluate the clinical effect of mandibular posterior vertical osteotomy for the treatment of condylar osteochondroma. Methods: Nine cases of condylar osteochondroma treated with condyle removal and reconstruction of condylar pedicled with pedicled mandibular branch were retrospectively studied in our hospital from 2004 to 2009. Through imaging, occlusal relationship and temporomandibular joint Function of a comprehensive assessment. RESULTS: After at least 8 months of follow-up, the occlusal relationship, facial features and joint function of all patients recovered well after condyle reconstruction. Radiographic examination showed that the upper edge of the posterior margin of the mandibular branch was located within the joint socket and gradually transformed into a smooth oblate spherical shape with the passage of time. CONCLUSION: The vertical posterior margin of the mandibular branch posterior pedicel pedicled upwards is an ideal method to reconstruct the condylar defect caused by osteochondroma resection.
