Comments on “Double-Blind Comparison of Ultrasonic and Conventional Osteotomy in Terms of Early Postoperative Edema and Ecchymosis”

I read the manuscript by Ilhan et al¹ with great interest. The authors performed a randomized study comparing two types of osteotomy in rhinoplasty: ultrasonic and conventional osteotomy. They found that ultrasonic osteotomy results in less edema and ecchymosis. Their patients were blind to the study and not informed about which osteotomy technique was applied to them. The same surgeon performed both types of surgery and was not blinded. The postoperative evaluation of the surgical results was performed by blinded examiners. Although the authors called their study a "double-blinded" comparison, I do not agree with them.
