Abstract

Objectives: 1. Describe the role of studies using flexible endoscopy in the diagnosis of sleep apnea. 2. Describe the role of flexible endoscopy in the diagnosis of sleep apnea. Subjects and methods: Overview of arguments on the role of flexible sleep endoscopy in diagnosing sleep apnea. A comprehensive search of 3 databases was conducted including Pubmed, Cochrane and ScienceDirect. We synthesized 615 relevant documents, then reviewed the documents by title and abstract, excluded 585 duplicate documents, and included the remaining 30 documents in the full-text analysis. After analyzing the full-text articles, 13 documents were included in the study. Results: There were 3011 patients in 13 studies included in the analysis, including 6 cohort studies (2 prospective, 4 retrospective); 6 descriptive studies (4 cross-sectional, 2 case series) and 1 case-control study. There were 3 studies in Asia, 5 in Europe, and 5 in America. The studies focused on the use of flexible endoscopy during sleep in the setting of patients with various degrees of sleep apnea syndrome (mild, moderate, and severe). The average age was usually 40-60 years (ranging from 38.9 ± 9.26 to 60.4 ± 11.0). The majority of patients were overweight BMI>25 or class I obese in all studies (ranging from 25.3 ± 7.5 to 30.5 ± 7.9). The mean AHI (events/hour) ranged from moderate to severe (18.5 ± 12.6 to 43.4 ± 26.6). Flexible endoscopy plays a role in determining the degree of collapse (mainly multilevel) and the anatomical location of the obstruction (the palate is the most common location at 62.7%, and the epiglottis is the least common location at 7.3%) in the diagnosis of sleep apnea.
