Background: Rhinoplasty 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. Aim: To 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. Results: Histopathologically, 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. Conclusions: The 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.
