Development of swelling following orthognathic surgery at various cooling temperatures by means of hilotherapy-a clinical, prospective, monocentric, single-blinded, randomised study

The study results indicate slightly less residual swelling in group 1 (18 °C) on the 30th post-operative day. One possible reason for this, based on the design of the study, could be the lower cooling temperature. The post-operative pain development exhibits a comparable level of pain intensity between the two groups. In overall terms, a subjectively more agreeable treatment was observed in group 1 (18 °C).
