The Effect of Injection of Saline Adrenaline (1/100000) 15ml versus 5ml on the Skin Edema and Thickness in Rhinoplasty Intraoperative

Abstract Background Nasal skin edema is a common result of soft and bony tissue trauma during rhinoplastic procedures. In a cosmetic surgery like rhinoplasty, skin edema can fade the cosmetic results and can lead to dissatisfaction for both the surgeon and the patient. Local saline /adrenaline injection is claimed to reduce the nasal skin edema intraoperative. Aim of the work To assess effect of injection of saline adrenaline (1/100000) 15ml versus 5ml on the skin oedema and thickness during rhinoplasty through thesis study. Subjects and Methods In this study 30 cases of rhinoplasty will be operated, 15 cases will be injected by saline adrenaline (1/100000) of 5ml and the others 15 cases will be injected by saline adrenaline (1/100000) of 15 ml, then measuring the skin oedema after 10 minutes of saline adrenaline (1/100000) injection, after 30 minutes and after 60 minutes of the injection at three sites; the dorsum, supratip and the tip of the nose by Seal Gouge Caliper (surgical caliber). Results the intraoperative skin edema was significantly decreased with local injection of large amount (15ml) of saline /adrenaline 1/100000 than the usual injected amount (5ml) saline /adrenaline 1/100000 specially at the tip and the supratip of the nose and specially at 30 min and 60 min after injection, but statistically significance difference only at 60min at the dorsum. Conclusion that the skin oedema much less with injection of 15ml of saline adrenaline (1/100000) in comparison to injection of 5ml of saline adrenaline (1/100000).
