buccal space

The buccal space (also termed the buccinator space) is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space in the cheek, and is paired on each side. The buccal space is superficial to the buccinator muscle and deep to the platysma muscle and the skin. The buccal space is part of the subcutaneous space, which is continuous from head to toe.
