How should the patient's mouth be positioned for APOM imaging?

• A. Closed tightly
• B. As wide as possible
• C. Slightly open
• D. In a relaxed position

Answer: (B)

For an Anterior-Posterior Open Mouth (APOM) imaging, the patient's mouth should be positioned as wide as possible. This positioning allows for optimal visualization of the odontoid process (dens) and the lateral masses of the atlas. When the mouth is wide open, it creates a clear path for the x-ray beam to capture the necessary anatomical structures without obstruction from the teeth or alveolar structures, ensuring that the images are diagnostic and clear. The open-mouth position also helps to align the cervical spine in a way that minimizes superimposition of adjacent structures, which is crucial for accurate interpretation of the images. This imaging technique is specifically designed to evaluate the upper cervical spine and the relationship between the dens and the atlas, making proper mouth positioning vital for effective imaging.
