Dear Editor,

I read the manuscript written by Taskın et al. [1] with great interest. The authors performed a randomized study comparing two types of osteotomy in rhinoplasty: piezoelectric and conventional osteotomy. They did not find a significant difference between these osteotomies. Although the authors stated their study is “double-blinded” in the abstract section, I do not agree with them.

In this study, 90 patients were randomized into two groups: conventional and piezoelectric osteotomy. The same surgeon did all operations. A blinded examiner evaluated the postoperative ecchymosis and edema of the patients. This is the only blinding in this study. That is why this study is not double blinded as stated in the abstract section. This situation is probably overlooked and needs to be corrected.
