Concurrent elevation of the upper lateral cartilage perichondrium and nasal bone periosteum for management of dorsum: the perichondro-periosteal flap.

A meticulous nasal dorsal dissection is an indispensable tool for a successful rhinoplasty. To achieve an aesthetically pleasing dorsum, fine dissection of the upper lateral cartilages (ULC), nasal bones, and keystone area is crucial. In this Featured Operative Technique article, the author describes a different concept of nasal dorsal skeletonization: the perichondro-periosteal flap technique. This technique has several advantages in restoring the nasal dorsum after hump reduction. Namely, the preparation and protection of the perichondrium and the periosteum of the nasal dorsum as a single entity allows a healthier, separate-layer closure over the osseocartilaginous dorsum.
