How Does Open‐Mouth Breathing Influence Upper Airway Anatomy?

Objectives/Hypothesis: Open‐mouth breathing during sleep may increase the severity of obstructive sleep apnea (OSA) and complicate nasal continuous positive airway pressure (CPAP) therapy in patients with OSA. The aim of this study was to assess the effect of open‐mouth breathing on upper airway anatomy using lateral cephalometry and fiberoptic nasopharyngoscopy.
