Evaluation of the Obstruction Localization with Sleep Endoscopy in Obstructive Sleep Apnea Patients
Journal Title: Hippocrates Medical Journal - Year 2021, Vol 1, Issue 1
Abstract
Abstract Objective The aim is to evaluate awake and sleep endoscopy (SE) findings in patients with obstructive sleep apnea syndrome (OSAS) with NOHL (nose-oropharynx-hypopharynx-larynx) classification, to reveal the differences between the two methods and to determine whether the severity of OSAS is related to anatomical localization. Materials and Methods OSAS patients were included in the study. Patients were divided into three groups as mild, moderate and severe OSAS. SE was performed with sedation to all patients. Endoscopic findings were scored according to the NOHL classification. Results Seventy patients were included in the study. In the awake endoscopic examination, only one level of obstruction was detected in 6 patients, while two or more levels of obstruction were detected in 64 patients. When SE findings were evaluated, there was no change in the level of obstruction in 6 patients in the mild group, 6 patients in the moderate group, and 4 patients in the severe group, while a change in the obstruction level was found in the other patients. These changes were found to be statistically significant (p<0.001). Conclusion In recent years, it has been reported that the treatments applied as a result of the evaluation of the level and pattern of obstruction are more successful. While collapse in the upper respiratory tract is at a single level in a few patients, it is detected at multiple levels in many patients. Collapse and anatomical condition determined by SE are extremely important in treatment management and are reported to be preferred to standard awake endoscopy
