Applications of the M-arch model in nasal tip refinement

The M-arch model of nasal tip dynamics provides an elaboration and modernization of the tripod concept to better permit understanding of the effects of various tip-altering maneuvers on the overall form and function of the tip complex. It defines the tip complex as paired arches whose overall length determines the major nasal parameters. This length may be adjusted at numerous points within the arch to effect specific desirable changes. This article provides a practical account of the M-arch model with case-based examples to better demonstrate its applicability.
