The effect of external ultrasound waves on ecchymosis, edema and pain after facial aesthetic surgery

Abstract

Background and objective: Facial cosmetic procedures are often associated with unsightly postoperative ecchymosis, and swelling, which may be a source of pain and anxiety for patients and can be difficult to camouflage. This study was conducted to assess the safety and efficacy of low frequency 3MHz pulsed ultrasound (US) in the treatment of ecchymosis and swelling after facial cosmetic procedures. Methods: Thirty patients undergoing facial cosmetic surgery had been involved and randomly divided into two equal groups. Ultrasound group (US-group, n=15), who received 3MHzpulsed US at 1.5 W/cm2for 5 minutes to each side of the face, and control group (n=15). Postoperative assessment included severity of ecchymosis, postoperative pain, and amount of facial swelling. All measurements were performed by blinded investigator at postoperative days (P0Ds).l,3,5,7,10 Results: Complete resolution of ecchymosis, pain and facial swelling was observed between POD5 toPOD7 in US group. While in control group resolution and reduction of pain and facial swelling occurred at POD7 to POD10. Conclusion: Postoperative US therapy helps in early resolution and reduction of facial swelling and pain after facial cosmetic surgery with no reported complications or side effects
