Introduction: Sleep endoscopy is a technique that allows a direct visualization of the pharynx during drug-induced sleep. It allows an assessment of the anatomical site of obstruction or vibration in habitual snorers.
Materials and methods: A total of 51 patients underwent sleep endoscopy. All answered a standard questionnaire and underwent an otolaryngological exam as a part of the diagnostic procedure.
Results: The most frequent site of obstruction was the palate in 90.4%, followed by the base of the tongue in 38.5%. Obstruction at multiple levels was found in 60.7% of patients. No correlations were found between the level of the obstruction found in the ENT examination and the one found during the sleep endoscopy.
Conclusions: Sleep endoscopy is useful for the assessment of the usual snorer and we recomend it to label the patient's obstruction.
