High resolution anatomical information on the structure and function of the upper airway and surrounding soft tissue structures can be obtained with modern imaging techniques. In particular, MR imaging and CT scanning allow precise anatomic examination of the airway and surrounding soft tissue structures. Additionally, dynamic imaging techniques can allow us to study dimensional changes in the upper airway soft tissue and bony structures during respiration, sleep and airway closure.
The clinical indications, advantages and disadvantages of various upper airway imaging and assessment techniques in the OSAS patients are discussed and literatures are reviewed in this article.
