Abstract

ntroduction: Considering the high prevalence of obstructive sleep apnea syndrome (OSAS) and its complications, proper diagnosis and treatment is particularly important. Since the standard diagnostic test for OSAS is polysomnography, which is not widely available, finding a simple, available, and cheap diagnostic method is very helpful. The aim of this study was to evaluate the efficiency of anterior rhinomanometry and upper respiratory tract examination in diagnosis of the OSAS.
Materials and Methods: In this observational analytic study, all patients referred to BAMDAD sleep clinic for polysomnography from Feb 2007 to Jul 2007 were evaluated by anterior rhinomanometry as well as upper respiratory tract examination and results were compared with each other.
Results: Of 66 patients participated in our study, 31 patients were in the normal group, 19 in mild apnea group, and 16 in moderate to severe apnea group. The results of ENT examination showed clear obstruction in 22 patients. 12 of them were in moderate to severe apnea group, and 9 of them in mild apnea group. Only one patient with abnormal examination was in the normal group. The respiratory tract resistance which was measured by anterior rhinomanometry showed no significant association with positive results of polysomnography.
Conclusion: Our study showed that although anterior rhinomanometry is invalid for diagnosis of OSAS, ENT examination (such as noctural oxymetry) can be a useful diagnostic method for OSAS.
