title: Obstructive sleep apnea syndrome. A review.
abstract: Obstructive sleep apnea syndrome (OSAS) is a complex disorder characterized by a sleep-related collapse of the upper airway. The most likely candidate for the common pathway linking various abnormalities casually associated with OSAS (such as adenotonsillar hypertrophy, obesity, retro- or micrognathia, acromegaly, or more subtle structural anomalies) is an abnormally small upper airway lumen. Symptoms of OSAS that appear during sleep include snoring, abnormal motor activity, disturbed nocturnal sleep, a sensation of choking, heartburn, nocturia, nocturnal enuresis, and heavy sweating. Daytime waking symptoms are dominated by often profound sleepiness, which may secondarily be associated with automatic behavior, retrograde amnesia, hypnagogic hallucinations, personality changes, sexual difficulties, and headaches. Careful evaluation, both sleeping and waking, are essential to select appropriate treatment. Treatments include nasal continuous positive airway pressure, tracheostomy, weight loss, uvulopalatopharyngoplasty, mandibular advancement, and so forth.
