Description

The sublingual space is shaped like an inverted V with its apex pointing anteriorly and is located between the tongue musculature superiorly and the anterior one-third of the mylohyoid muscle inferolaterally which separates it from submandibular space. 

Boundaries

  • Posteriorly: as the sublingual space is not encapsulated by any fascial layer, it freely communicates along the posterior free border of the mylohyoid muscle with the submandibular and parapharyngeal spaces.
  • Anteriorly: the two sublingual spaces are communicating just below the frenulum via a small isthmus.
  • anterior border (apex): mandible
  • superior border: floor of mouth and intrinsic tongue muscles
  • medial border: geniohyoid and genioglossus muscle complex
  • lateral border: mylohyoid muscle

 

Contents

  • sublingual gland and duct
  • deep portion of the submandibular gland and duct
  • lingual nerve, artery and vein
