Surgical Importance of Nasal SMAS in Open Rhinoplasty

Open rhinoplasty became the standard approach in primary rhinoplasty. There is no available literatures about planes of dissection whether; subcutaneous, sub SMAS or subperiosteal. Subcutaneous plane was studied in this study. It was found to be the most convenient plane of dissection, as it is safe, rapidly and easily performed. Nasal muscles are preserved which guarantee animated nose postoperatively. Avoidance of cutting the connection between the depressor septi nasi and the levator septi nasi prevents occurrence of postoperative drooping of the nasal tip. There was less injury of vessels and lymphatics which causes less postoperative edema even in the early period.
