We describe our experience with conservative condylectomy for the correction of facial asymmetry in five patients with osteochondroma of the mandibular condyle. All five patients presented with malocclusion and facial asymmetry, which are common clinical findings of osteochondroma involving the mandibular condyle. We performed conservative condylectomy without additional orthognathic surgery for all five patients, preserving the vertical height of the condylar process as much as possible. Following surgery, intermaxillary traction using a skeletal anchorage system with rubber elastics was performed on all patients to improve occlusion, and, when necessary, additional minimal orthodontic treatment was performed. The mean follow-up period was 42 months. At the last follow-up visit, all patients exhibited satisfactory facial symmetry and remodeling of the remaining condyle, with stable health and no signs of recurrence. In conclusion, conservative condylectomy alone, without subsequent orthognathic surgery, is adequate for the restoration of facial symmetry and the preservation of vertical condylar height in select patients with condylar osteochondroma.
我们描述了对5例下颌髁突骨软骨瘤患者采用保守性髁突切除术矫正面部不对称的经验。所有5例患者均表现出错牙合及面部不对称,这是累及下颌髁突的骨软骨瘤常见的临床特征。我们对所有5例患者均进行了保守性髁突切除术,未进行额外的正颌手术,尽可能保留髁突的垂直高度。术后,对所有患者使用带有橡胶弹力线的骨锚固系统进行颌间牵引以改善咬合,必要时进行额外的微量正畸治疗。平均随访期为42个月。在最后一次随访时,所有患者面部对称性良好,剩余髁突发生重塑,健康状况稳定,无复发迹象。总之,对于某些髁突骨软骨瘤患者,单独进行保守性髁突切除术,不进行后续正颌手术,足以恢复面部对称性并保留髁突垂直高度。
