The M-Arch model: a new concept of nasal tip dynamics.

The M-Arch Model introduced herein expands on the utility and simplicity of the tripod concept to consider the overall length of the cartilaginous tripod arch as the major determinant of nasal tip parameters. Surgeons may exploit this powerful tool using modern grafting, suture, and cartilage-cutting techniques to predictably achieve desired tip alterations and, by extension, more consistently satisfactory aesthetic outcomes.
