Which projection of the skull demonstrates the sella turcica in profile?

The lateral projection of the skull is the correct choice for demonstrating the sella turcica in profile. In this position, the patient's head is positioned with the lateral aspect facing the receptor, allowing for a clear view of the anatomical structures in profile, including the sella turcica, which is part of the sphenoid bone and houses the pituitary gland. Additionally, the lateral projection minimizes superimposition of other structures, thereby providing a more accurate representation of the sella anatmically.

In contrast, the frontal projection focuses on the anterior aspects of the skull, which does not give the same profile view of the sella turcica. The transoral projection is designed to visualize structures through the oral cavity and may not adequately demonstrate the sella turcica in profile. The AP axial projection also does not effectively showcase the sella turcica in profile, as it is more directed toward the cranial vertex and offers a different perspective than what is provided by the lateral view. Thus, the lateral projection serves as the best option for clearly visualizing the sella turcica.
