Understanding Dorsal Preservation Rhinoplasty: Anatomy and Biomechanics

Abstract

Application of dorsal preservation rhinoplasty techniques requires an in-depth understanding of the underlying nasal anatomy. A key tenant of dorsal preservation rhinoplasty is maintaining the relationship between the upper lateral cartilages and nasal bones. In this study, the authors discuss the pertinent nasal anatomy, surgical approaches to the nasal septum and bony pyramid, management of blocking points, and fixation of the lowered dorsum. They also introduce a new dorsal fixation method termed the "dorsal osseocartilaginous horizontal mattress" suture developed by the senior author for application in cases of combined structural and open dorsal preservation rhinoplasty.
