Double-Blind Comparison of Ultrasonic and Conventional Osteotomy in Terms of Early Postoperative Edema and Ecchymosis.

[BACKGROUND] Edema and ecchymosis are common complications of rhinoplasty. Modifications to osteotomy may reduce edema and ecchymosis and ameliorate postoperative discomfort in patients who undergo rhinoplasty.

[OBJECTIVES] The authors performed osteotomy with conventional instruments or with an ultrasonic device and compared these methods with respect to the severities of ecchymosis and edema in the early postoperative period.

[METHODS] Fifty-six patients who underwent primary rhinoplasty with medial oblique, low-to-high internal osteotomy performed conventionally or with an ultrasonic device were evaluated in a prospective study. Photographs of the patients on postoperative days 3 and 7 were scored for ecchymosis and edema by 2 physicians who did not perform the operations and were blinded to the osteotomy procedure.

[RESULTS] Ecchymosis scores on postoperative days 3 and 7 and edema scores on postoperative day 3 were significantly higher for the 22 patients who underwent conventional osteotomy than for the 34 patients who underwent ultrasonic osteotomy, as scored by both examiners. Edema scores on postoperative day 7 were significantly higher for conventional than for ultrasonic osteotomy as assessed by 1 examiner but were not significantly different as determined by the other examiner.

[CONCLUSIONS] The results of this comparative study suggest that rhinoplasty with ultrasonic osteotomy is associated with less edema and ecchymosis in the early postoperative period than is rhinoplasty with conventional osteotomy.
