Question: A 38 year old male is referred for consideration of surgical options for obstructive sleep apnea.  He is particularly interested in the Inspire(R) upper airway stimulator device.  His BMI is 31, AHI is 33, and he is unable to use CPAP.  Drug-induced sleep endoscopy is completed that demonstrates collapse at the level of the tongue base as well as concentric palatal collapse.  Which of the above features of his history or sleep endoscopy render him a poor upper airway stimulation candidate?
