BACKGROUND: the Apnea syndrome / Obstructive Sleepy Hypopnea (SOHAS) is define by the American Academy of Sleep with recurrent presence of episodes of partial or total obstruction in the superior airways during sleep, in addition to showing a reduction (hypopnea) or complete stoppage (apnea) of airflow, although there is an ongoing maintenance of inspiratory efforts. SOHAS motivates the so-called sleepy chronic snoring and sleepiness to dress up by the stop of airflow by at least 10 seconds. The diagnosis is carried out through polysomnographic examination, which consists of the simultaneous recording of body activities during the night, indicating the number of occurring apneas and hypopneas and SOHAS severity. For the successful of disorder treatment it is essential to get an accurate diagnosis and correct actions with a multidisciplinary team, where the Speech Therapist is included. PURPOSE: to analyze, through literature, the interaction of Speech Therapist and SOHAS. CONCLUSION: with this study, we can identify SOHAS complexity and show the importance of performance in speech therapy for these patients for a better quality of life.
