The sublingual spaces are paired suprahyoid deep spaces of the head and neck located below the tongue.
Gross anatomy
The sublingual space is a part of the floor of mouth .
As the sublingual space is not bounded by fascia posteriorly, some authors consider the sublingual space a component of the submandibular space . More commonly, however, the sublingual and submandibular spaces are discussed separately .
Each sublingual space communicates with contralateral sublingual space via a small isthmus just below the frenulum.
Boundaries
It is like an inverted V with its apex pointing anteriorly and is located between:
- superiorly: intrinsic muscles of the tongue
- inferolaterally: mylohyoid muscle
- posteriorly: freely communicates along the posterior border of the mylohyoid muscle with the submandibular and parapharyngeal spaces
- anteriorly: mandible
- medially: geniohyoid/genioglossus complex
