title: Nasal tip deprojection with crural cartilage overlap: the M-arch model.
abstract: Vertical arch division is a mainstay of tip surgery, and its applications are expanding. It allows deprojection of the overprojected tip, and modifies rotation, length, and lobule definition. These parameters can be altered in a controlled, predictable fashion when the alar cartilage is preserved and overlapped, maintaining its strength. Cartilage overlay techniques aim to preserve normal anatomy and establish support for the nasal framework. We discuss the uses of vertical arch division when applied to the M-arch model, an expansion of the nasal tip tripod concept, which provides for a utilitarian approach to surgical techniques for the nasal tip.
