Presentation transcript:

Case 1. Case 1. Axial CT image reveals fractures of the lateral and anterior walls of the left maxillary antrum. Herniation of low attenuation fat into the maxillary sinus is evident. The lateral maxillary antrum fragments form a “flap valve” trapping portions of the buccal fat pad within the antrum. Note a minimally displaced fracture of the left lateral pterygoid plate. Other images (not shown) demonstrated minimally displaced fractures of the left lateral orbital wall and left zygomatic arch. N. Hines, and G.
