The aim of orthognathic surgery is to produce a more aesthetic facial skeletal appearance, and improve jaw function. This prospective study, aimed to evaluate the impact of orthognathic surgery on quality of life for patients with dentofacial deformity, and whether it was clinically meaningful. 62 consecutive patients were recruited (27 male, 35 female) aged 18-38 years. Baseline data were collected using a validated health status measure (Orthognathic Quality of Life Questionnaire (OQLQ)) and a visual analogue scale (VAS). Postoperative questionnaires (OQLQ, VAS) and a Global Transition Scale (GTS) were completed at 6 months after completion of treatment and compared with pre-treatment scores. Following surgery, there was a significant (p<0.05, paired t test) improvement in OQLQ scores for each domain. The proportion of patients reporting a moderate or large improvement was: facial appearance (93%), chewing function (64%), comfort (60%) and speech (32%). Clinical relevance of change scores was reported in terms of effect sizes, and the largest effect was on facial aesthetics. The clinical impact was moderate on social aspects of deformity and oral function and a small effect on awareness of facial deformity. This research reaffirms that orthognathic surgery has positive effects on quality of life.
正颌手术的目的是改善面部骨骼的美观，并改善颌骨功能。本前瞻性研究旨在评估正颌手术对牙颌面畸形患者生活质量的影响，以及其是否具有临床意义。共招募了 62 名连续患者（27 名男性，35 名女性），年龄在 18-38 岁之间。使用经过验证的健康状况衡量标准（正颌质量生活问卷（OQLQ））和视觉模拟量表（VAS）收集基线数据。在治疗完成后 6 个月完成术后问卷调查（OQLQ、VAS）和全球过渡量表（GTS），并与治疗前的评分进行比较。手术后，每个领域的 OQLQ 评分都有显著（p<0.05，配对 t 检验）改善。报告中度或大幅度改善的患者比例为：面部外观（93%）、咀嚼功能（64%）、舒适度（60%）和言语（32%）。以效应大小的形式报告了变化分数的临床相关性，最大的影响是面部美学。手术对畸形的社会方面和口腔功能的临床影响是中等的，对面部畸形的认识影响较小。这项研究再次证实，正颌手术对生活质量有积极影响。
