    BackgroundRhinoplasty is a common surgical procedure used in nose esthetics and pathologies. Shaping the nasal bones is a crucial step in achieving successful rhinoplasty surgery. However, complications such as excessive bleeding, edema, mucosal damage, and periosteal damage may occur during osteotomy for nose shaping.AimTo investigate the damage to soft tissue and the effects on oxidative stress and proinflammatory cytokines in the blood caused by osteotomy performed on rabbits, using different osteotomy methods. Methods: Thirty-two albino New Zealand rabbits were divided into four groups. Group A was the sham group (n = 8), Group B the piezoelectric device group (n = 8), Group C the manual saw group (n = 8), and Group D the classical osteotomy group (n = 8). About 3 ml of blood was drawn to compare preoperative and postoperative interleukin-1ß (IL-1ß), thiobarbituric acid-reactive substances (TBARS), tumor necrosis factor-alpha (TNF-alpha), nitric oxide (NO), interleukin-10 (IL-10), and glutathione (GSH) levels. A 1 mm3 piece of soft tissue from the nasal bone of each animal in the study groups was sent for histopathological examination. The Chi-square test was used to analyze the incidence of postoperative necrosis, inflammation, and edema in the groups.ResultsHistopathologically, edema was significantly higher in Group C and Group D compared to Group B. Inflammation was increased in all groups. The necrosis was significantly higher in Group B compared to Group C and Group D. Except for two parameters, no significant changes were found in the biochemical markers for all groups.ConclusionsThe piezoelectric device was found to be a better option for reducing edema and inflammation, while manual saws and classical osteotomy may lead to more tissue damage.Copyright © 2024 Copyright: © 2024 Nigerian Journal of Clinical Practice.
