Sonographic Anatomy and Pathology: Paranasal Sinuses and Midface

The midface region is an area that contains important anatomical structures and there are many different radiographic modalities for the evaluation of normal anatomy, abnormality, and fractures in the region. US machine is portable compared to the other imaging methods, gives clinician immediate feedback, and allows making correct examination in a timely manner. In maxillofacial region traumas, the selection of the imaging technique is an important issue. USG is promising and can be considered successful in diagnosing the midfacial bone fracture, but its use is limited in evaluating bone-surrounded air spaces such as the paranasal sinuses.
