The pterygoid fossa is a depression located on the lateral surface of the sphenoid bone, a small facial bone found in the skull. It is a crucial landmark for dental and facial surgery because it houses the pterygoid muscles, which play a significant role in mastication. However, for those looking for synonyms for this anatomical feature, alternative terms include the pterygoid notch, pterygopalatine fossa, infratemporal fossa, and lateral pterygoid plate. Despite the variety of terms available, all of these phrases describe the same area of the skull and still hold relevance in medical and dental fields.
