Abstract
The piezo surgery was reported to cause minimal trauma to the soft tissue. The aim of this study was to compare the periorbital edema and ecchymosis after transcutaneous lateral osteotomy in rhinoplasty using 2-mm osteotome versus Piezo scalpel respectively. In a randomized clinical trial and split-mouth-design, we performed primary rhinoplasty in 15 patients (7 men, 8 women; age 18–35 years, mean age 26.6 ± 5.7 years). Transcutaneous lateral osteotomy was performed using a 2-mm osteotome on the one side and a piezo scalpel on the opposite side. We took digital photographs of the face on 1, 3, 7 and 14 postoperative days. Three examiners used a standard 5-point Kara-Gokalan scale to assess the early postoperative periorbital edema and ecchymosis on each side. We found more difficult to use the piezo scalpel via only one incision and found easier to use two stab incisions for inserting the piezo scalpel. The time spend for each osteotomy was similar (P > 0.05). The inter-observer agreement was high (> 0.676). The postoperative edema showed to be significantly different on day 1, 3 and 7 (P-value < 0.05), ecchymosis was much less on piezo side but not significantly. It was more difficult to use piezo scalpel via only one incision. The piezo scalpel showed to reduce the postoperative edema significantly and improved the ecchymosis. Swelling and bleeding could have crossed the midline and blurred the comparison of two sides. However, this is the best design to achieve the highest similarity in study condition.
