With the patient's head rotated 53 degrees.the orbit centered to the film and the central ray directed vertically to the mid –pont of the film and. One obtains a view of the:
- a- Optic foramina
- b- Mastoid process
- c- Sphenold slnus
- d- Dorsum sella.
The correct answer is: a. Optic foramina
Here's why:
- Head rotation:
With the patient's head rotated 53 degrees, a specific view known as the submentovertex radiograph is achieved. This projection visualizes structures located around the base of the skull, particularly on the side facing the X-ray beam.
- Orbit centered to the film:
By centering the orbit on the film, the ray traverses through the orbital region and into the skull base on that side.
- Central ray directed vertically to the mid-point of the film:
This angulation penetrates the skull base from a superior perspective, further emphasizing structures in that area.
Combining these factors, the submentovertex radiograph with the described positioning provides a clear view of the optic foramina, which are two openings located at the back of the orbit for the passage of the optic nerves.
Other Options:
Here's an explanation of the other options:
b. Mastoid process:
While the mastoid process is located in the skull base, the submentovertex radiograph with this specific angulation wouldn't provide an optimal view of it.
c. Sphenoid sinus:
Similarly, the sphenoid sinus, located further within the skull base, wouldn't be prominently visualized in this projection.
d. Dorsum sella:
The dorsum sella, a bony prominence on the upper part of the sphenoid bone, might be partially visible in this view, but the optic foramina would be the most pronounced and specific landmark.
Therefore, considering the described patient positioning and central ray angulation, the most likely structure visualized in this scenario is the optic foramina.
Remember, accurate interpretation of radiographs requires a deeper understanding of anatomical structures and imaging techniques. Always consult with a qualified radiologist for definitive diagnosis based on specific patient information and complete radiographic examination.
