Abstract

Drug Induced Sleep Endoscopy (DISE) is an important hub in diagnostic pathway of patients affected by Obstructive Sleep Apnea Syndrome (OSA) providing useful information that can be useful for all the different professionals involved in this patient’s management involving surgical or medical [1,2] decisions such as determining the exact anatomical structure involved in obstruction. During the procedure can be performed different test that can predict efficacy of different treatments such as mandibular advancements, hypoglossal stimulation and Mandibular advancement device fitting test that can further improve therapy addressing and surgical planning [3]. Knowing the anatomical site involved and the obstruction mechanism can lead to minimize the effort and combining multiple therapeutic approaches to maximize results and minimize side effects. Now there is no standard consensus on which classification to adopt and regional consensus as European Position Paper on DISE [4] are still not universally applied, therefore there are no Italian data on the most common obstruction pattern on a large population sample.
