Infratemporal crest

Infratemporal Crest is a bony ridge located on the greater wing of the sphenoid bone. It separates the temporal and infratemporal surfaces of the greater wing.

Etymology

The term "Infratemporal Crest" is derived from the Latin words "infra" meaning below, and "temporal" referring to the temporal bone of the skull. The "crest" refers to the ridge-like structure.

Anatomy

The Infratemporal Crest is a part of the sphenoid bone, which is one of the seven bones that make up the orbit. The sphenoid bone is situated in the middle of the skull towards the front, in front of the temporal bones and basilar part of the occipital bone. The greater wing of the sphenoid bone extends laterally from the body of the sphenoid bone and ends in the Infratemporal Crest.

The Infratemporal Crest separates the temporal surface, which faces upwards and to the side, from the infratemporal surface, which faces downwards and to the side. The temporal surface forms part of the middle cranial fossa and the infratemporal surface forms part of the infratemporal fossa.

Clinical Significance

Due to its location, the Infratemporal Crest can be involved in various medical conditions and procedures. For instance, fractures involving the sphenoid bone may also affect the Infratemporal Crest. Such fractures can occur due to high-impact trauma to the skull and can lead to complications such as cranial nerve injuries and cerebrospinal fluid leaks.
