title: [How frequent are pathologic ENT findings in patients with obstructive sleep apnea syndrome?].
abstract: Several studies have been reported suggesting a relationship between pharyngeal obstruction due to ENT pathology and the sleep apnea syndrome (SAS). To determine the incidence of pathological ENT findings that may present symptoms similar to SAS, we performed ENT examination, fiberoptic nasopharyngoscopy, rhinomanometry and partial audiometry and electronystagmography in 431 patients who had undergone polysomnography for clinically suspected SAS. 336 patients were referred for ENT examination; 95 patients had some kind of ENT disease and therapy before polysomnography. In the first group 31% showed one or more pathological ENT finding (ears 9%, nasopharynx 2%, nose 19%, oropharynx 5%, larynx 5%, neck 1%); 10.5% had pathology in two regions and 0.7% in three regions. An ENT operation was indicated in 23%, usually for nasal obstruction. ENT findings included chronic otitis media, adenoids, enlargement of lingual tonsil and vocal cord pathology, but no patient had a malignant tumor or severe pharyngeal obstruction. We conclude that severe anatomical abnormalities or dysplastic syndromes are rare; only 2 SAS patients had acromegaly due to hypophyseal adenoma and 1 patient without SAS had craniofacial dysplasia. However, ENT examination frequently revealed severe nasal obstruction due to septal deviation, polyposis or adenoids. These findings emphasize the need for ENT examination and therapy before application of CPAP (continuous positive air pressure) therapy.
