The comparison of edema and ecchymosis after piezoelectric and conventional osteotomy in rhinoplasty

Abstract

The basic aim of our study is to compare the results of the conventional and piezoelectric osteotomy in rhinoplasty by complete subperiosteal degloving of nasal bone to minimize soft-tissue injury. The study was designed as a prospective, double-blind, randomized, and controlled study. Setting is a tertiary referral hospital in Turkey. Ninety patients who underwent primary open rhinoplasty with osteotomy, performed by either the conventional instruments or the piezoelectric device. The complete subperiosteal degloving of the entire nasal bone was done up to the nasal maxillary sulcus, medial canthus, and nasion in all patients, independent of the type of osteotomy device used. Patients subsequently underwent median-oblique and lateral osteotomy, either with an ultrasonic device or a conventional 2-mm guarded, straight osteotome. The postoperative edema and ecchymosis were evaluated by another surgeon who was blinded to the osteotomy procedure on postoperative days 2 and 7. The edema scores were significantly increased on the second day compared with the seventh day in both groups 1 and 2. However, there was no significant difference between groups. The ecchymosis scores were slightly higher in postoperative day 2, compared with day 7, in both groups 1 and 2, but statistically not significant. This study showed that the main reason edema and ecchymosis are seen post-rhinoplasty is related to soft-tissue injury during osteotomy.
