Airway evaluation is critical for surgical decision making. In patients with obstructive sleep apnea (OSA), a minimal evaluation should include a basic head and neck physical examination to evaluate for overt pathology. An upper airway examination will also provide insight into identifying patients with a higher risk of OSA. For patients who are evaluated for surgery, endoscopy combined with cephalometrics is the most accepted method of identifying patients with retroglossal collapse and obstruction. A new paradigm suggests that most patients have multilevel obstruction, so examination should be directed at assessing risk factors to direct the aggressiveness of surgical intervention.
