한국 성인 남성 폐쇄성 수면무호흡증 환자에서의 수면내시경 소견

Background and Objectives: Drug-induced sleep endoscopy (DISE) is one of the common techniques that visualize the upper airway dynamics during sleep in patients with obstructive sleep apnea (OSA). Authors tried to present the DISE results and to investigate the their relationship with polysomnography (PSG) findings. Materials and methods: Authors enrolled 31 male adults who were diagnosed with OSA between March 2011 and February 2012 at Pusan National University Yangsan Hospital. The data including age, body-mass index (BMI), Friedman staging, DISE findings and PSG results such as apnea-hypopnea index (AHI) and positional dependency were collected by retrospective chart reviews. Results: In DISE, 87.0% (27/31) showed the retropalatal airway obstruction and 48.4% (15/31) showed the retroglossal airway obstruction. Among them, 35.5% (11/31) showed obstructions in both the retropalatal and retroglossal airway. The retroglossal airway obstruction was not related with age, BMI or AHI but with Friedman’s palatal position and positional dependency (p=0.020 and 0.029, respectively). Conclusions: Freidman’s palatal position may be a good predictor of the retroglossal airway obstruction. This study suggests that a palatal airway surgery plus a positional therapy or a mandibular advancement device can be tried even in severe OSA patients with the retroglossal airway obstruction.
