Functional Nasal Surgery.

[LEARNING OBJECTIVES] After studying this article, the participant should be able to: (1) understand the functional significance of nasal anatomy as it relates to rhinoplasty and perform a comprehensive functional nasal assessment. (2) Identify the anatomical level of obstruction based on the authors' algorithmic approach and understand the current evidence supporting operative techniques for correcting nasal airway obstruction from septal deformity, inferior turbinate hypertrophy, internal nasal valve collapse, external nasal valve collapse. (3) Understand the current evidence supporting operative techniques for correcting nasal airway obstruction from septal deformity, inferior turbinate hypertrophy, internal nasal valve collapse, and external nasal valve collapse. (4) Appreciate the objective assessment tools for functional nasal surgery from a clinical and research perspective.

[SUMMARY] The intent of functional rhinoplasty is to improve nasal airflow (and the perception thereof) by surgically correcting the anatomical sources of obstruction in the nasal airway. Cosmetic and functional rhinoplasty are not mutually exclusive entities, and the techniques that address one area, inevitably may affect the another. The rate of functional problems after cosmetic rhinoplasty range from 15 to 68 percent with nasal airway obstruction found to be the most common indication for secondary surgery. The objective of this CME article is to provide readers with an understanding of the (1) functional components of nasal anatomy, (2) clinical functional assessment, and (3) the current evidence supporting corrective maneuvers for each component.
