Sublingual Space
The sublingual space is located below the mouth and above the mylohyoid muscle and is part of the suprahyoid group of fascial spaces.
Sublingual space. The submental space is a fascial space of the head and neck sometimes also termed fascial spaces or tissue spaces. It is a potential space located between the mylohyoid muscle superiorly the platysma muscle inferiorly under the chin in the midline. It is a potential space located below the mouth and above the mylohyoid muscle and is part of the suprahyoid group of fascial spaces.
The sublingual space is located on both sides of the tongue superomedial to the mylohyoid muscle and lateral to the midline geniohyoid genioglossus muscle complex 1 2. Sublingual and buccal medication administration are two different ways of giving medication by mouth. There is an unavoidable overlap between the conditions discussed in this chapter and in those considering oral cavity pathology since the sublingual space sls is an important component of the floor of the mouth.
As the sublingual space is not bounded by fascia posteriorly some authors consider the sublingual space a component of the submandibular space 2. The sublingual space is a part of the floor of mouth 1. More commonly however the sublingual and submandibular spaces are discussed separately 3 5.
The sublingual space sls is located inferior to intrinsic muscles of the oral tongue lateral to the genioglossus geniohyoid complex and superomedial to the mylohyoid muscle. It is a potential space located below the mouth and above the mylohyoid muscle and is part of the suprahyoid group of fascial spaces. The sublingual space is bounded between the mylohyoid muscle and the geniohyoid and genioglossus muscles.
The sublingual space is a fascial space of the head and neck sometimes also termed fascial spaces or tissue spaces.
