Abstract
Objectives: The purpose of this prospective cohort study was to assess weight loss in kg following orthognathic surgery focusing on gender, type of surgery, employment, and living arrangements, as effect modifiers.
Material and methods: Patient weights were measured at four points during their trajectory; two weeks preoperatively, week one, week three, and week eight postoperatively. Additionally, the registered nurse collected the following information: (1) patient age; (2) gender; (3) status of employment; (4) type of surgery; and (5) living arrangement.
Results: Mean weight loss of 3.35 kg (95% CI [confidence interval] = 3.07 to 3.62, P < 0.001), 3.56 kg (95% CI = 3.23 to 3.89, P < 0.001), and 2.79 kg (95% CI = 2.36 to 3.21, P < 0.001) for week 1, 3 and 8. Higher weight loss was observed in males 3.81 kg (95% CI = 3.31 to 4.31) compared with females 3 kg (95% CI = 2.71 to 3.29) at week 1 (P = 0.01). Highest weight loss following bimaxillary surgery was observed at week 1 (P = 0.00) and week 8 (P = 0.04).
Conclusions: Postoperative proportional weight loss is observed in all patients undergoing orthognathic surgery. Being male and having bimaxillary surgery predicts for a higher weight loss. Patients who had bimaxillary procedures showed greater weight loss compared to those who had a single jaw procedure, possibly due to longer surgery times, increased facial swelling and restricted mouth opening. Interestingly, living arrangements seemed to have an effect on weight loss at week 3, suggesting that social support may influence nutritional status.
目的：本前瞻性队列研究的目的是评估正颌手术后体重减轻（kg），并将性别、手术类型、就业和生活安排作为影响因素。材料和方法：在患者运动轨迹的四个点测量患者体重；术前2周，术后1周，3周，8周。此外，注册护士还收集了以下信息：(1)患者年龄；(2)性别;（三）就业状况；（四）手术类型；（五）生活安排。结果：第1、3和8周平均体重减轻3.35 kg （95% CI = 3.07至3.62,P < 0.001）、3.56 kg （95% CI = 3.23至3.89,P < 0.001）和2.79 kg （95% CI = 2.36至3.21,P < 0.001）。在第1周，男性体重减轻3.81 kg (95% CI = 3.31 ~ 4.31)，而女性体重减轻3 kg (95% CI = 2.71 ~ 3.29) （P = 0.01）。双颌手术后第1周（P = 0.00）和第8周（P = 0.04）体重减轻最多。结论：所有接受正颌手术的患者术后体重均按比例减轻。做过双颌手术的男性减肥效果更好。与单颌手术相比，接受双颌手术的患者体重减轻更多，这可能是由于手术时间更长、面部肿胀加剧和张嘴受限。有趣的是，生活安排似乎对第三周的体重减轻有影响，这表明社会支持可能会影响营养状况。
