Buccal space
Buccal Space
The Buccal Space (pronounced: buk-uhl speys) is a fascial space of the head and neck. It is a potential space located on either side of the face, adjacent to the cheek or buccinator muscle.
Etymology
The term "buccal" is derived from the Latin word "bucca," which means cheek. The term "space" in this context refers to a potential space, which is a region within the body where tissue layers are not normally in contact but can be separated by pathological processes or medical interventions.
Anatomy
The buccal space is bordered anteriorly by the buccinator muscle, posteriorly by the masseter muscle, superiorly by the zygomaticus muscle, and inferiorly by the mandible. It contains the buccal fat pad and buccal branches of the facial nerve.
