What is panoramic technique?
Panoramic dental x-ray uses a very small dose of ionizing radiation to capture the entire mouth in one image. It is commonly performed by dentists and oral surgeons in everyday practice and may be used to plan treatment for dentures, braces, extractions and implants. This exam requires little to no special preparation.

An irregular cavity within the anterosuperior aspect of the bone is called the mastoid (or tympanic) antrum, which communicates with the attic of the tympanic cavity 1.
What can affect the mastoid process?
