Submandibular space

Submandibular 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 progresses in the facial tissues. The submandibular space is located below the mandible and is continuous with the sublingual space on its superior aspect.

Etymology

The term "submandibular" is derived from the Latin words "sub" meaning under and "mandibula" meaning jawbone.

Anatomy

The submandibular space is a potential space that is located below the mandible. It is bordered by the mylohyoid muscle inferiorly, the hyoglossus muscle and middle constrictor muscle medially, and the mandible laterally. The space is divided into superficial and deep parts by the mylohyoid muscle. The superficial part is located between the mylohyoid muscle and the skin, while the deep part is located between the mylohyoid muscle and the hyoglossus muscle.

Clinical significance

Infections in the submandibular space can lead to a condition known as Ludwig's angina, which is a type of cellulitis that can be life-threatening. The infection can spread to other fascial spaces of the neck and can cause difficulty in breathing, swallowing, and speaking. Treatment typically involves antibiotics and sometimes surgical intervention to drain the infection.
