Semidorsal Preservation Techniques With Ostectomy for Narrowing the Nasal Roof.

Dorsal hump deformity is prevalent in Caucasians because of their nasal structure. The dorsal preservation techniques became more popular in recent years. However, there is still not a clear solution for patients who have nasal hump deformity and a wide nasal roof. The present study aims defining a new technique that combines push-down or let-down procedures with ostectomy in patients who have nasal hump deformity and a wide nasal roof. In the present research, the records of patients were assessed retrospectively. The patients who had nasal hump deformity and who have undergone either push-down or let-down approaches were included. The push-down or let-down techniques used in this study involved ostectomy to reduce the nasal hump and narrow the nasal roof. The initial median Rhinoplasty Outcome Evaluation score before surgery was 57.5, which significantly improved to 93.00 points at 12 months after surgery ( P <0.001). The study suggests that experienced surgeons using push-down and let-down techniques can achieve better esthetic results in patients with a wide nasal roof.
