Indications, Stability, and Surgical Outcomes of Using Osteochondral Nasal Septal Graft as a Septal Extension Graft in Rhinoplasty Patients: A Prospective Cohort Study.

Septal extension graft (SEG) is an adaptable tool that controls, supports, and stabilizes the nasal tip projection, rotation, length, and shape. Recent studies comparing SEGs to more conventional columellar strut grafts found that SEGs provided improved results. This prospective cohort study included 66 patients divided into 2 groups based on their indications. Group 1 was patients who underwent septorhinoplasty using osteochondral septal extension graft (OSEG), and group 2 underwent septorhinoplasty using cartilaginous SEG. The main reason for undergoing OSEG was insufficient septal cartilage (P<0.001). The outcomes were not significantly different between both groups, with the % of patients who experienced positive outcomes ranging from 78.8% to 97%. The OSEG is a safe, valid, and effective option in septorhinoplasty that can be used in patients with insufficient cartilaginous septum.
