The association of sleep apnea with daytime hypersomnolence without obesity, and its potentially lethal cardiopulmonary sequelae, make it crucial that this condition be distinguished from narcolepsy. A patient with retrognathia who had been diagnosed as a narcoleptic for 15 years had the primary complaint of excessive daytime sleepiness. Sleep laboratory evaluation showed severe hypoxemia and a mean of 366 upper airway obstructions per night. The patient was treated with a tracheotomy; this resulted in relief of the sleep-related upper airway obstructions, hypoxemia, and hypersomnolence.
