X-Ray Mastoid (Right) (AP View) Test

Mastoid is a vital structure of the inner ear. Although this is called a bone, the mastoid doesn’t have the structure as rigid or solid like any other bones. It is made of air sacs and resembles a sponge. For proper functioning of mastoid, it must receive air from other parts of the ear that includes the Eustachian tube, which connects your middle ear to the rear of your throat. Any infection developed in the middle ear, blocks the Eustachian tube, which may then lead to an infection in the mastoid bone, which is mastoid bone infection of the skull, or mastoiditis. This X-ray process is one of the few series of tests done to diagnose and treat Mastoiditis.

No special preparation is needed. Keep the medical practitioner informed about any medical conditions or medication been taken or allergies, for the doctor to take necessary measurements. Any special head wearings are to be avoided for better x-ray. No restrictions on the food prior to the test. Sometimes a separate apron is to be worn to reduce exposure to radiation. Pregnant women must inform their doctor prior taking the x-ray test.

Examination of the mastoid can be made possible with the AP view which is also called posteroanterior and anteroposterior. The X-ray beam is directed either postero anteriorly or antero posteriorly along the orbito-meatal line at an angle of 90 degrees to the film.
