'''Submental Space'''

The '''Submental 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 infection processes result in a pathologic accumulation of fluid, cells, or debris.

==Etymology==
The term "submental" is derived from the Latin words "sub" meaning "under" and "mentum" meaning "chin". Therefore, the submental space is the space located under the chin.

==Anatomy==
The submental space is located between the [[mylohyoid muscle]] and the [[platysma muscle]]. It is bounded by the anterior belly of the [[digastric muscle]]s laterally, the [[hyoid bone]] inferiorly, and the [[mandible]] superiorly. The submental space communicates with the [[submandibular space]] bilaterally.

==Clinical significance==
Infections in the submental space can result from dental infections, trauma, or surgery. These infections can spread to other fascial spaces, leading to conditions such as [[Ludwig's angina]] or [[necrotizing fasciitis]]. Treatment typically involves antibiotics and surgical drainage.
