| Summary: | Objective:To evaluate the effects of nasal septal surgery and type of nasal packing used on local and systemic oxidative stress.Methods:Fifteen patients who were scheduled for septoplasty under local anaesthesia with isolated septal deviation were included in the study. Venous blood samples were collected preoperatively, postoperatively upon anterior nasal packaging, immediately after nasal packaging was removed and 2 hours following removal of nasal packaging. At the start of the incision and just after removal of the nasal packaging 2x2-mm sized nasal mucosal samples were taken. Malonylaldehyde (MDA) was measured as a parameter of local oxidative stress, and glutathione (GSH) and superoxide dismutase (SOD) as parameters of the local antioxidant system. Systemic MDA, catalase and nitric oxide were measured.Results:GSH and SOD levels decreased postoperatively in the septal mucosa just after nasal package removal, whereas MDA increased significantly (p<0.001). Systemic MDA levels decreased in comparison to preoperative levelsbetween the phases, however NO and catalase levels increased (p<0.05, p<0.01).Conclusion:Local oxidative stress occurs after septoplasy operation but no biochemical effect is observed systemically. Local oxidative stress is influenced by surgical intervention, surgical technique and packing material. New comparative studies are required between study groups with no nasal packaging.
