Effects of Water-Circulating Cooling Mask on Postoperative Outcomes in Orthognathic Surgery and Facial Trauma

Abstract

The purpose of this study was to perform a systematic review and meta-analysis of randomized clinical trials (RCTs) investigating the efficacy of hilotherapy on postoperative pain, swelling, neurosensory impairment and patient satisfaction. The authors analyzed RCTs comparing the use of hilotherapy versus conventional cryotherapy or no cold treatment for orthognathic surgery and repair of facial trauma. The authors assessed the risk of bias and strength of evidence according to the Cochrane guidelines and GRADE rating system, respectively. Treatment effects were defined as weighted or standardized mean difference using the inverse variance method. Five RCTs were included. Postoperative pain and swelling in patients using hilotherapy were lower comparing to the control group in the postoperative day 2 (Pain: MD −1.75, CI 95% −2.69 to −0.81; Swelling: MD −21.16 mL, CI 95% −38.91 to −3.41) and in the final evaluation (Pain: MD −0.31, CI 95% −0.44 to −0.18; MD −4.45 mL, CI 95% −7.87 to −1.03). Patients reported higher satisfaction with hilotherapy, but no differences were found for neurosensory impairment. Current evidence suggests that hilotherapy is effective in reducing postoperative pain and swelling in orthognathic surgery and repair of facial fractures and may lead to improvements in patient satisfaction in the recovery phase.

Evaluation of edema formation and salivary EGF related to 810 nm diode laser and conventional surgery after frenectomy

“…18,37 Postoperative edema reaches its maximum level 2 or 3 days after surgery procedure. 15 In this study, the presence of edema was evaluated by taking 2D cephalometric photographs and face scans at 3rd day, and 14th day. 18 In this study, the 3D face scans on T1 and T3 were superimposed using the fine registration (ICP-Iterative Closest Points) algorithm method, and a difference map was created.…”

“…13 Anti-inflammatory drugs, cold application, or different surgical devices and adjunctive effects to reduce edema were compared. 1,14,15 The elastic tape measurement method is the most common method to measure the amount of edema. 14,16 The tape method has disadvantages, such as measuring by direct contact with the patient, reducing comfort, and the possibility of making the measurement incorrect.…”
