Craniofacial, Sleep apnea syndrome, Iranian


Objectives: As craniofacial and anthropometric parameters seem to affect this disease and these parameters differ between ethnicities, this study was aimed to assess these correlations in Iranian population.

Method: This cross-sectional study was done on 73 patients that were referred to Baharloo hospital for overnight polysomnography in order to approve OSAS. Meanwhile, their craniofacial and anthropometric indices including weight, height, neck circumference (NC), waist circumference (WC), hip circumference (HC), head length (HL), head width (HW), total face height (TFH), upper face height (UFH), and face width (FW) were measured after obtaining informed consent. Body mass index (BMI), cephalic index (CI), total facial index (TFI), and upper facial index (UFI) were calculated based on measured parameters. Apnea-Hypopnea index (AHI) was extracted from polysomnography results. Then correlations between AHI and other parameters in total, males, and females were analyzed by SPSS software and 0.05 was the significance level.

Results: This study showed that mean CI was correlated with AHI in males (p=0.024) and mean HL was correlated with AHI in females (p=0.008). The dominant head form was dolichocephalic in males and hyper-brachycephalic in females. The dominant face form was hyper-leptoprosopic in either genders.

Conclusion: Cephalic index in males and head length in females correlate with OSAS in Iranian population.
