Its complex anatomy often makes diagnosis and treatment of pathologies in this region difficult. Moreso, the vital structures within this region makes comprehension of this region key for safe surgical resections. Here we develop an anatomically accurate 3D model for the PPF and the integral structures contained within.

Data related to variations, relationships, and dimensions of structures from anatomical studies were also used to deduce accurate relationships and identify known common anatomical variants of structures within the PPF. Finally, a medical illustrator used these data to develop a 3D anatomical model. The PPF is a clinically important area that transmits structures necessary for many functions in the head, including tear production, sensation over the maxilla, and supply of inner facial and nasopharyngeal structures.
