Ans. D: Protruding jaw Predisposing factors to the sleep apnea/ hypoapnea syndrome include being male, which doubles the risk probably due to a testosterone effect on the upper airway, and obesity, found in about half of the patients, because parapharyngeal fat deposits tend to narrow the pharynx. Nasal obstruction or a recessed mandible can fuher exacerbate the problem Acromegaly and hypothyroidism also predispose by causing submucosal infiltration and narrowing of the upper airway
