Abstract
Introduction: Obstructive sleep apnea syndrome (OSAS) is a serious and life threatening disorder caused by various anatomic and physio-pathologic factors. This study was conducted to clarify some anatomic etiologic factors of OSAS and the role of body mass index (BMI) in expression of its symptoms.
Materials and Methods: In this case-control study 127 patients were included. Sixty patients had OSAS symptoms and 67 patients were considered as controls. Cephalometric parameters from lateral skull view of CT scan and BMI of patients were statistically analyzed and compared between two groups.
Results: The position of hyoid bone was significantly lower and soft palate was significantly larger in patients with OSAS symptoms than control group. Moreover, mean BMI measurement was significantly higher in the patient group.
Conclusion: Our results suggest that in addition to apparent role of BMI in OSAS symptoms, increased soft tissue compartment of pharyngeal area and position of hyoid bone are significant etiologic factors in this syndrome.
