The sublingual space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space [ 1 ] located below the mouth and above the mylohyoid muscle , and is part of the suprahyoid group of fascial spaces.
The submaxillary space is a historical term for the combination of the submandibular, submental and sublingual spaces, which in modern practice are referred to separately or collectively termed the perimandibular spaces. [7]
The submandibular space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space , and is paired on either side, located on the superficial surface of the mylohyoid muscle between the anterior and posterior bellies of the digastric muscle . [ 1 ]
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 , [ 1 ] under the chin in the midline.
Ludwig's angina is a form of severe, widespread cellulitis of the floor of the mouth, usually with bilateral involvement. Infection is usually primarily within the submandibular space, and the sublingual and submental spaces can also be involved.
Traveling with the lingual nerve, the fibers of chorda tympani enter the sublingual space to reach the anterior 2/3 of the tongue and submandibular ganglion. [ 4 ] The special sensory fibers originate from the taste buds in the anterior 2/3 of the tongue and carry taste information to the nucleus of solitary tract of the brainstem , where taste ...
The most usual source of the mucin spillage is the sublingual salivary gland, but ranulae may also arise from the submandibular duct or the minor salivary glands in the floor of the mouth. A cervical ranula occurs when the spilled mucin dissects its way through the mylohyoid muscle , [ 1 ] which separates the sublingual space from the ...
It attaches to the mandible along a line that separates the sublingual and submandibular space. If an infection begins above the mylohyoid's point of attachment, then the infection will spread to the sublingual space. If the infection originates below the mylohyoid's point of attachment, then the infection will spread to the submandibular space.
