Sinus - Special Views - Video Lesson

In this view, we will be demonstrating the Infro Superior submental vertex sinus projection. The submental vertex sinus horizontal beam full basal view should be performed with the patient standing or sitting at the upright bucky. With a forty inch source to image distance and no tube angulation. The submental vertex view, I have my patient standing at the upright Buckey, I have aligned to the mid sagittal plane to the long axis line. We will hyper extend the neck placing the vertex of his head against the IR. The central ray is at the mid sagittal plane directly through the selle turcica perpendicular to the IOML. And it is three quarters of an inch anterior to the EAM, which is the external
