Mental space (anatomy)

Mental Space (Anatomy)

The Mental Space is a fascial space of the head and neck (also termed fascial spaces or tissue spaces). It is a potential space and can become an actual space if disease or trauma causes a pathologic break in the fascial planes.

Anatomy

The mental space is located in the facial region of the human body. It is a potential space located between the mentalis muscle and the overlying skin. It is bound superiorly by the lower lip and inferiorly by the body of the mandible. The mental space communicates with the submental space and the submandibular space.

Clinical Significance

Infections in the mental space can result from dental abscesses or trauma to the chin. These infections can spread to the submental and submandibular spaces, leading to Ludwig's angina, a potentially life-threatening condition.
