Canine space

Diagram showing muscles of the infra-orbital reigon. Levator anguli oris is colored red. The canine space is situated between the levator anguli oris muscle and the levator labii superioris muscle.

The canine space (also termed the infra-orbital space), is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a thin potential space on the face, and is paired on either side. It is located between the levator anguli oris muscle inferiorly and the levator labii superioris muscle superiorly. The term is derived from the fact that the space is in the region of the canine fossa, and that infections originating from the maxillary canine tooth may spread to involve the space. Infra-orbital is derived from infra- meaning below and orbit which refers to the eye socket.
