title: [Obstructive apnea during sleep: clinical and polygraphic evaluation of 150 cases].
abstract: Obstructive sleep apnea is one of the most common causes of excessive daytime sleepiness. In our sample, clinical evaluation generally suggested this diagnosis by daytime sleepiness (90.6%) and loud snoring (92.0%). Respiratory pauses and inspiratory gasps were frequently reported (12.6%). The age of presentation was after the fourth decade in 87.2%. Polysomnography was characterized by numerous obstructive or mixed apneas, with mean apnea index 37.1; frequent arousals following the apneas; reduction or abscence of stages 3 and 4; reduction of sleep efficiency; hypoxemia and EEG arrhythmias during the respiratory pauses. Tracheostomy was performed in 45 cases, uveopalatopharyngoplasty in 43 and both surgeries in 5, as treatment of choice.
