Comparison of Functional and Cosmetic Outcomes Between Dorsal Preservation and Spreader Flap Rhinoplasty: A Randomized Trial.

Background: Preservation rhinoplasty is a novel and increasingly utilized method in nasal plastic surgery.
Objectives: The study aimed to compare the functional and aesthetic outcomes of dorsal preservation rhinoplasty, a new and interesting method, with conventional hump resection.
Methods: A total of 84 rhinoplasty applicants were randomly assigned to 2 groups. The first group underwent convention dorsal hump resection with spreader flap midvault reconstruction and the second group underwent dorsal preservation rhinoplasty with the modified subdorsal strip method. Aesthetic and functional outcomes, including residual hump, nasal width, projection, and rotation, were evaluated after 1 year with the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS), visual analog scale (VAS), and image analysis.
Results: Eighty-four patients with a mean age of 30.96 ± 6.75 years were recruited, of whom 15 (17.6%) were male. There were no significant differences in confounding variables between the 2 groups. There were no significant differences in residual hump (P = .11), nasal width (P = .37), projection (P = .70), rotation (P = .79), VAS (P = .81), or SCHNOS (P = .90) between the 2 groups.
Conclusions: Dorsal preservation rhinoplasty with the modified subdorsal strip method may have comparable aesthetic and functional outcomes to spreader flaps midvault reconstruction.
