Evidence-based Nasal Analysis for Rhinoplasty: The 10-7-5 Method.

Rhinoplasty is one of the top 5 aesthetic surgical procedures performed in plastic surgery. A methodical evaluation based on solid and up-to-date scientific evidence in different key areas of nasal and facial analysis is presented, the 10-7-5 method. This represents the most important preoperative step for a successful rhinoplasty. The 10-7-5 method for nasal analysis is a useful instrument that provides the rhinoplasty surgeon a deep comprehension of nasal anatomy. Understanding the nasal structures' main relationships and consequences of each surgical maneuver on nasal framework assists on establishing the appropriate surgical goals for each patient, both in primary and secondary rhinoplasty cases. This systematic analysis of patient's frontal, lateral, and basal nasal views provides a background to identify changes to ideal aesthetic proportions and how to surgically restore them while maintaining gender and ethnic congruency.
