Pterygoid fossa

Pterygoid Fossa

The Pterygoid Fossa is a significant anatomical structure located in the human skull. It is a part of the sphenoid bone, which is one of the seven bones that make up the orbit (eye socket). The Pterygoid Fossa is situated on the inferior aspect of the sphenoid bone, between the pterygoid processes.

Etymology

The term "Pterygoid" is derived from the Greek words "pteryx" and "eidos", which mean "wing" and "form" respectively. This is in reference to the wing-like shape of the pterygoid processes, which flank the Pterygoid Fossa.

Anatomy

The Pterygoid Fossa is a deep, concave space bordered by the lateral and medial pterygoid plates. These plates are extensions of the sphenoid bone. The fossa is home to the pterygoid muscles, which play a crucial role in mastication (chewing).

Clinical Significance

Due to its location and the structures it houses, the Pterygoid Fossa is often involved in surgical procedures involving the sinuses and nasal cavity. It is also a key landmark in imaging studies of the skull and face.
