摘要：Introduction and Objective. Obstructive sleep apnea (OSA) is characterized by at least 5 ten-second-long episodes ofapnea or hypopnea, per hour of sleep. This disease may lead to severe, life-threatening complications. Therefore, risk analysisand its influence on disease intensity is crucial for proper implementation of preventive treatments.Objective. To determine the relation between the intensity of OSA expressed in Apnea-Hypopnea Index (AHI), and theanterior-posterior diameter of upper airways at the levels of soft palate and tongue base.Material and Method. Medical records of 41 patients with sleep apnea (AHI>4) diagnosed through polysomnographicexamination obstructive were used for the study. The data consisted of: age and gender, polysomnographic examinationresults (AHI), lateral cephalogram with cephalomertic analysis, together with measurements of the upper and lowerpharyngeal depth according to McNamara. Statistical analysis was carried out in accordance with Pearson’s r correlationcoefficient test (Statistica 8.0 software package).Results. Analysis of the influence of upper airways diameter on the intensity of OSA showed that the value of upper airwaysdiameter at the tongue base level had no statistically significant impact on the value of AHI (p=0.795). However, a statisticallysignificant impact of the value of upper airways diameter on the AHI value (p=0.008) at the soft palate level was observed.Patients with OSA have narrowed upper airways diameter. The value of AHI increases with the decrease of upper diameterand is not dependent on a lower diameter value. Patients with a decreased upper airways diameter should be informedabout potential breathing disorders during sleep
