Background: The aim of this paper was to determine the most common craniofacial changes inpatients suffering Obstructive Sleep Apnea Syndrome (OSAS) with regards to the degree ofobesity. Accordingly, cephalometric data reported in the literature was searched and analyzed.Methods: After a careful analysis of the literature from 1990 to 2006, 5 papers with similarprocedural criteria were selected. Inclusion criteria were: recruitment of Caucasian patients withan apnea-hypopnea index (AHI) >10 as grouped in non-obese (Body Mass Index – [BMI] < 30) vs.obese (BMI ≥ 30).Results: A low position of the hyoid bone was present in both groups. In non-obese patients, anincreased value of the ANB angle and a reduced dimension of the cranial base (S-N) were found tobe the most common finding, whereas major skeletal divergence (ANS-PNS ^Go-Me) was evidentamong obese patients. No strict association was found between OSAS and length of the soft palate.Conclusion: In both non-obese and obese OSAS patients, skeletal changes were often evident;with special emphasis of intermaxillary divergence in obese patients. Unexpectedly, in obese OSASpatients, alterations of oropharyngeal soft tissue were not always present and did not prevail.
