Orthognathic surgery is routinely practiced, yet little comparative data exists to evaluate post-orthognathic surgery diet protocols.
To evaluate which postoperative diet protocols are recommended and to quantify post-orthognathic surgery weight changes in our institutional cohort.
An internet search was carried out on Google for "orthognathic surgery diet" and the postoperative diet recommendations from centers worldwide were quantified. Additionally, a retrospective analysis of patients that underwent orthognathic surgery at our institution was performed, and their preoperative and postoperative weights were recorded.
The internet search yielded 58 centers that met our inclusion criteria. Most centers were in the United States (n = 37, 63.8%) and were oral and maxillofacial surgeon (OMFS)-led centers (n = 39, 67.2%). Postoperative diets were categorized into 7 distinct protocols, ranging from most to least restrictive-the most popular was liquid diet for 2 to 4 weeks followed by soft diet for 2 to 6 weeks. There were no significant patterns observed across different geographical regions or specialties.In our institution, 135 patients were identified. Overall, there was an average maximum weight loss of 4.1 kg by week 4, followed by a gradual increase in weight. Linear regression analysis showed that patients with greater preoperative body mass index (BMI) lost more weight postoperatively than patients with lower BMI (R = 0.25, < .001).
There is a significant variability in recommended postoperative diets following orthognathic surgery. Following a moderately restrictive diet at our institution, patients returned to their preoperative weight after approximately 4 months.
正颌手术是常规开展的，但很少有比较数据来评估正颌手术后的饮食方案。
评估哪些术后饮食方案是推荐的，并量化我们机构队列中正颌手术后的体重变化。
在谷歌上进行了“正颌手术饮食”的互联网搜索，并量化了来自世界各地中心的术后饮食建议。此外，对在我们机构接受正颌手术的患者进行了回顾性分析，并记录了他们术前和术后的体重。
互联网搜索共产生了 58 个符合我们纳入标准的中心。大多数中心在美国（n=37，63.8%），并且是由口腔颌面外科医生（OMFS）领导的中心（n=39，67.2%）。术后饮食分为 7 种不同的方案，从最严格到最宽松-最受欢迎的是 2 到 4 周的液体饮食，然后是 2 到 6 周的软食。不同地理区域或专业之间没有观察到明显的模式。在我们的机构中，确定了 135 名患者。总体而言，第 4 周时体重最大下降 4.1 公斤，随后体重逐渐增加。线性回归分析显示，术前体重指数（BMI）较高的患者术后体重下降比 BMI 较低的患者更多（R=0.25， < .001）。
正颌手术后推荐的术后饮食存在显著差异。在我们的机构遵循适度限制饮食后，患者大约在 4 个月后恢复到术前体重。
