Palatal Anatomy and Phenotypes for the Treatment of OSA

Purpose of Review The purpose of the review is to provide background on palatal anatomy and phenotypes to better model the complex upper airway structure. Recent Findings Review of the literature identifies limited data on upper airway phenotypes and the associated palatal anatomy. The majority of literature evaluates sites of obstruction based on sedated endoscopy without describing the pharyngeal lumen and its characteristics. Upper airway anatomy is associated with different patterns and airway configurations. These can be described and may represent specific phenotypes. Additional research is needed to associate phenotypes with disease and treatment outcomes.
