Abstract:
Obstructive sleep apnea (OSA) results from a structural compromise of the upper airway combined with decrease in muscle tone during sleep. Overt upper airway pathology is rare, however a variety of pharyngeal tumors have been well described as a cause of OSA. We describe a case of a mass originating in the carotid body resulting in severe OSA with hypersomnia resistant to positive pressure ventilation.
