Orthognathic surgery is associated with side effects including severe postoperative swelling, pain, neurological dysfunction and trismus. The beneficial effects of localised cold treatment on postoperative swelling have been described. Topographical considerations make it difficult to quantify facial swelling. A new and promising method to measure facial swelling seems to be optical face scanning. This study aimed to evaluate the 3D optical scanner to measure soft tissue swelling following orthognathic surgery. Postoperative swelling was treated either with conventional cooling by cold packs or with the water-circulating cooling device Hilotherm Clinic. Secondary endpoints in each group included postoperative pain, neurological complaints, duration of hospital stay, trismus and patient satisfaction. The use of the cooling device by Hilotherm significantly reduced postoperative swelling, pain and hospital duration compared with conventional cooling. Postoperative trismus and satisfaction with the cooling method was significantly higher in the Hilotherm group compared with conventional cooling. No differences were observed concerning neurological score and outcome. In conclusion, 3D optical scanning is a simple and precise method of quantifying face swelling after orthognathic surgery. Hilotherm significantly reduces swelling and duration of hospital stay compared with conventional cooling.
正颌手术相关的副作用包括严重的术后肿胀、疼痛、神经功能障碍和牙关紧闭。局部冷疗对术后肿胀的有益效果已有描述。由于解剖位置的原因，量化面部肿胀比较困难。光学面部扫描似乎是一种新的、有前途的测量面部肿胀的方法。本研究旨在评估 3D 光学扫描仪测量正颌手术后软组织肿胀的效果。术后肿胀分别采用冷包装的常规冷却或 Hilotherm Clinic 循环水冷却装置进行处理。每个组的次要终点包括术后疼痛、神经症状、住院时间、牙关紧闭和患者满意度。与常规冷却相比，Hilotherm 冷却装置的使用显著减少了术后肿胀、疼痛和住院时间。与常规冷却相比，Hilotherm 组术后的牙关紧闭和对冷却方法的满意度明显更高。神经评分和结果无差异。总之，3D 光学扫描是一种简单而精确的方法，可用于量化正颌手术后的面部肿胀。与常规冷却相比，Hilotherm 显著减少了肿胀和住院时间。
