摘要：Objectives This study was designed to evaluate the correlation between CT findings and data from the physical examination and the Friedman Staging System (FSS) in patients with obstructive sleep apnea (OSA). Methods Retrospective evaluation by reviewing the medical records of 33 patients (19 males and 14 females) with mean body mass index (BMI) of 30.38 kg/m2 and mean age of 49.35 years. Among those patients 14 presented severe OSA, 7 moderate, 7 mild and 5 subjects were healthy. RESULTS Patients were divided into two groups according to the Friedman Staging System (FSS). Group A patients contained FSS I and II and group B FSS III. A positive relationship by Fisher‘s exact test between the FSS and Apnea-Hypopnea Index (AHI) (p¼0.011) and between FSS and BMI (p¼0.012) was found. There was no correlation between age (p¼0.55) and gender (p¼0.53) with the FSS. The ANOVA test comparing the volume of the airway between the two groups showed p¼0.018. CONCLUSIONS In this sample the Friedman Staging System and volume of upper airway show inverse correlation and are useful in analyzing the mechanisms of airway collapse in patients with obstructive sleep apnea.
