A modified Towne's view for radiography of the orbit and maxillary antrum

Routine radiographic examination of the paranasal sinuses and facial bones does not adequately demonstrate the posterolateral margin of the orbital floor. An anteroposterior projection with a 20 degrees cephalo-caudad angulation centered at the glabella adequately demonstrates the posterior and lateral orbital floor and the posterolateral margin of the orbital floor in all patients.
