This study analyzed the outcomes of nongrowing patients with unilateral mandibular hypoplasia treated according to a specific protocol, which combines distraction osteogenesis, orthodontic treatment, and conventional osteotomies.
The patients treated were objectively evaluated. Patient's satisfaction was assessed by questionnaire. Surgical changes were analyzed using cephalometry and three-dimensional facial surface data before surgery (T0) and at long-term (T1) follow-up.
Four patients were included in this study. The normalization of facial proportion and a high increase in symmetry were evident. Residual defects were documented in the postoperative symmetry of the chin. In the questionnaire, all patients gave favorable responses to their facial changes; for most of the objective parameters, all patients improved.
A multistage treatment protocol for the correction of facial deformities in patients with unilateral mandibular hypoplasia is a valid procedure for skeletal and occlusal stability. An evident improvement of the facial appearance is also achieved.
本研究分析了根据特定方案治疗的单侧下颌骨发育不全非生长型患者的治疗结果，该方案结合了牵引成骨、正畸治疗和传统截骨术。
对接受治疗的患者进行客观评估。通过问卷调查评估患者满意度。使用头影测量法和术前（T0）及长期（T1）随访时的三维面部表面数据分析手术变化。
本研究纳入4例患者。面部比例正常化且对称性显著提高。术后下巴对称性存在残余缺陷。在问卷调查中，所有患者对其面部变化均给予积极反馈；对于大多数客观参数，所有患者均有改善。
用于矫正单侧下颌骨发育不全患者面部畸形的多阶段治疗方案是实现骨骼和咬合稳定性的有效方法。面部外观也有明显改善。
