A post-operative cooling method in oral and maxillofacial surgery is the cooling with hilotherapy. The aim of this study was the post-operative comparison of cooling temperatures of 18°C and 22°C. The parameters of this trial were swelling and the post-operative pain levels.
This study included 156 patients, divided into two groups among whom a mono-one, bignathic osteotomy or genioplasty was indicated. The post-operative assessment of swelling was performed using a 3D optical scanner. This examination was repeated on post-operative days 1, 2, 3, 7, 14, 30, and 90. The examination on day 90 served as a reference value in respect of swelling and pain.
Group 1 (18°C, 78 patients) showed an increase in post-operative swelling on the 1 post-OP day of 52.06 ± 35.41ml. The maximum was reached on the 2 post-OP day with 75.82 ± 38.97ml. On the 30 post-OP day, residual swelling measured 11.60 ± 12.62ml. Group 2 (22 °C, 78 patients) showed an increase in postoperative swelling on the 1 post-OP day of 76.07 ± 63.15ml. The maximum was reached on the 2 post-OP day with 106.97 ± 69.63 ml. On the 30 post-OP day, residual swelling measured 14.36 ± 32.26ml. The differences between the two groups and between different visits were statistically significant.
The study results indicate less residual swelling in group 1 on the 30 post-OP day, possible based on the lower cooling temperature. The post-operative pain exhibits a comparable level of pain intensity between the two groups. In overall terms, a subjectively more agreeable treatment was observed in group 1.
口腔颌面外科的一种术后冷却方法是冷疗。本研究的目的是比较 18°C 和 22°C 的术后冷却温度。该试验的参数为肿胀和术后疼痛水平。
本研究纳入了 156 名患者，分为两组，其中一组为单颌骨切开术、双颌骨切开术或颏成形术。术后肿胀的评估采用三维光学扫描仪进行。术后第 1、2、3、7、14、30 和 90 天重复检查。第 90 天的检查作为肿胀和疼痛的参考值。
第 1 组（18°C，78 例）术后第 1 天肿胀增加 52.06±35.41ml。第 2 天达到最大值，为 75.82±38.97ml。术后第 30 天，残留肿胀为 11.60±12.62ml。第 2 组（22°C，78 例）术后第 1 天肿胀增加 76.07±63.15ml。第 2 天达到最大值，为 106.97±69.63ml。术后第 30 天，残留肿胀为 14.36±32.26ml。两组之间和不同时间点之间的差异均有统计学意义。
研究结果表明，第 1 组在术后第 30 天的残留肿胀较少，可能是由于冷却温度较低。术后疼痛在两组之间表现出相似的疼痛强度。总体而言，第 1 组的治疗效果更令人满意。
