Feasibility of Dorsal Preservation Rhinoplasty for Hump Nose Reduction in Asian Population.

Background: Dorsal preservation rhinoplasty (DPR) has shown promise in Western populations for nasal hump reduction, but its feasibility and long-term outcomes in Asian individuals remain unexplored. Objective: To measure the feasibility, as well as the functional and aesthetic outcomes, of DPR in Asian hump noses and to determine its effectiveness in adaptation to the unique characteristics of the Asian demographic. Methods: A retrospective review analyzed patients who underwent primary DPR between April 2019 and November 2022 with a follow-up period of over 12 months. The study included patients whose photographs met the criteria. Surgical techniques, aesthetic measurements using anthropometric factors, and subjective outcomes were evaluated. Results: Of the 17 patients (11/17, 64.7% female), the mean age was 22.53 years (standard deviation [SD] 5.22 years). The median follow-up period was 36.90 months (range 13-61 months). Measurements from pre- and postoperative photographs showed a significant reduction in both nasofacial angle (7.76°, SD 4.30°) and rhinion angle (0.85°, SD 0.69°) (p < 0.0001). Patient-reported outcome scores with the Nasal Obstruction Symptom Evaluation scale decreased from 61.00 (SD 26.96) to 15.50 (SD 11.65), and Standardized Cosmesis and Health Nasal Outcomes Survey scores postoperatively were 10.90 (SD 7.71) overall, with the functional component at 3.50 (SD 2.64) and the aesthetic component at 7.40 (SD 6.24). No residual hump, recurrence of the hump, or complications were observed. Conclusion: In this study, the use of DPR techniques was effective and may support further development of the inclusion and exclusion criteria for its use in correcting the dorsal hump in Asian patients. Careful patient selection will be imperative to determine the ultimate indications for this technique.
