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 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 ...
The most common causes of enlargement of the submandibular lymph nodes are infections of the head, neck, ears, eyes, nasal sinuses, pharynx, and scalp. [1] The lymph glands may be affected by metastatic spread of cancers of the oral cavity, anterior portion of the nasal cavity, soft tissues of the mid-face, and submandibular salivary gland. [1]
Radical Neck Dissection (RND) – removal of all ipsilateral cervical lymph node groups from levels I through V, together with SAN, SCM and IJV. Modified Radical Neck Dissection ( MRND ) – removal of all lymph node groups routinely removed in a RND, but with preservation of one or more nonlymphatic structures (SAN, SCM and IJV).
Fascial spaces (also termed fascial tissue spaces [1] or tissue spaces [2]) are potential spaces that exist between the fasciae and underlying organs and other tissues. [3] In health, these spaces do not exist; they are only created by pathology, e.g. the spread of pus or cellulitis in an infection.
