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

Background: Nasal skin edema is a common result of soft and bony tissue trauma during rhinoplasty. 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. Objective: To assess effect of injection of saline adrenaline (1/100000) 15ml versus 5ml on the skin oedema and thickness during rhinoplasty through thesis study. Patients and Methods: In this study 60 cases of rhinoplasty will be operated, 30 cases will be injected by saline adrenaline (1/100000) of 5ml and the others 30 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).
