Conventional Resection Versus Preservation of the Nasal Dorsum and Ligaments: An Anatomic Perspective and Review of the Literature

Preservation rhinoplasty may refer to preserving several anatomic components including: the nasal bones, upper lateral cartilages, the keystone area and/or ligaments of the nose. Preserving the osseocartilaginous framework or “dorsal preservation” minimizes or completely avoids violation of the dorsal aesthetic lines’ architecture. Conventional hump reduction in open rhinoplasty disrupts these lines; however, it also provides versatility to reshape the entire dorsum. Surgical success with either technique requires a thorough understanding of the underlying nasal anatomy. © 2020 Elsevier Inc.
