The Cantilevered Spring Model

Richard W. Westreich, MD; William Lawson, MD, DDS

Arch Facial Plast Surg. 2008;10(3):170-179.

Objective  To extrapolate on the tripod concept to create a more universal and multiethnic model that includes common anatomical configurations and strategies to avoid certain unwanted surgical outcomes.

Methods  Analysis of current surgical methods, scientific studies, and predominant theories to produce a new model of nasal tip support based on the biomechanical properties of the nasal cartilages.

Results  The nasal tip acts as a cantilevered spring that associates with other rigid and semirigid regions of the nose. Application of these concepts resulted in preservation of projection and tip rotation in appropriately selected patients.

Conclusion  The cantilevered spring tripod provides a more universal model for explaining nasal tip dynamics in a contemporary multiethnic population of patients seeking functional or cosmetic rhinoplasty correction.
