1 Skull & Sinus Radiography Skull Radiography can be easily done erect with the patient seated in a chair or often time standing. It is easier to check for rotation with the patient seated. Sinus studies should always be done erect to see air and fluid levels in the sinuses. Sinus views can also be used to evaluate the facial bone and orbits.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
