Morphometric evaluation of the pterygoid hamulus and upper airway in patients with obstructive sleep apnea syndrome.

Our results showed that OSAS severity was associated with hamulus thickness, interpterygoid distance, and the ratio of interpterygoid distance to VL. Our study provides further insight into the pathophysiology of sleep apnea, suggesting that morphometric evaluation of the pterygoid hamulus and upper airway measurements can assist clinicians in stratifying and determining the best treatment options for patients with OSAS.
