Abstract

Nasal projection is a vitally important consideration during pre-operative planning, during rhinoplasty surgery itself and post-operatively it is a major determinant of the final result. A technique to create visual aids for analyzing a nose, particularly with regard to planning the ideal tip tip position, using a modified Guyoron approach is described The rhinoplasty surgeon must understandthe concepts of nasal projection and how surgical incisions and approaches may result in unplanned changes in this parameter.  The techniques for increasing or decreasing tip projection to produce a tip position that matches an ideal dorsal height and line are described, The relationship between tip projection and rotation and the nasal dorsum are explored.
