Proximal Intact Spreader Graft in Let-Down Dorsal Preservation Rhinoplasty.

Abstract: Grafts and flaps play significant roles in rhinoplasty procedures, while spreader grafts are commonly used. Spreader grafts are placed into submucosal pockets between the upper lateral cartilage and nasal septum. Occurrence of deviation can be seen on nondeviated noses after let-down or push-down methods are performed as the part of the upper septum that has been let-down may cause pressure on the lower septum and that results in deviation. In the present study, the author aimed to demonstrate the benefits of using a proximal intact spreader graft to support the nondeviated nasal septum or to correct the deviated septum in patients undergoing dorsal preservation rhinoplasty. In deviated noses, the upper septum is brought down to the opposite side of the deviation, and a proximal intact spreader graft is placed between the upper and lower septum to correct the deviation and make the dorsum nondeviated. This technique is suitable for patients with a slight to moderately deviated caudal part of the septum. It is unsuitable for patients with severe, cross, or S-shaped deviation. This technique aims to preserve the condition of the nondeviated nose and convert it into a nondeviated state in the let-down technique. The combination of proximal intact spreader graft and dorsal preservation rhinoplasty techniques effectively addresses dorsal hump and dorsal deviation deformities, enhances upper lateral cartilage concavity, prevents W-ASA segment collapse, and both prevents and improves internal nasal valve collapse. The data of patients who underwent dorsal hump reduction with the let-down technique were screened. According to inclusion and exclusion criteria, 95 patients were included in the study (68 females and 27 males). The ROE score before the operation was 51.5. After 12 months, it was found to be 91.5 points, and the change in the ROE median score was significant ( P < 0.001). This new proximal intact spreader graft method presents a suitable approach for surgeons to prevent any let-down-induced deviation problems that may occur after the procedure and to correct the present deviation. It will also lead to better cosmetic and functional outcomes for patients who have hump deformity.
