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 term submaxillary may be confusing to modern students and clinicians since these spaces are located below the mandible, but historically the maxilla and mandible together were termed "maxillae", and sometimes the mandible was termed the "inferior maxilla". Sometimes the term submaxillary space is used synonymously with submandibular space. [4]
The posterior part of this triangle contains the external carotid artery, ascending deeply in the substance of the parotid gland. This vessel lies here in front of, and superficial to, the external carotid, being crossed by the facial nerve, and gives off in its course the posterior auricular, superficial temporal, and internal maxillary branches: more deeply are the internal carotid, the ...
The pterygomandibular space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space in the head and is paired on each side. It is located between the medial pterygoid muscle and the medial surface of the ramus of the mandible .
The terminal part of the submandibular (Wharton's) duct is located in the mouth floor and opens as an orifice of the submandibular duct papilla. The position of the duct and its 0.5–1.5 mm wide ostium is invariably symmetric, but quite unpredictable; consequently, submandibular duct papillae can occasionally be challenging to recognize.
An abscess originating from a tooth which has spread to involve the buccal space. Above, deformation of the cheek on the second day. Below, deformation on the third day. Sometimes the buccal space is reported to be the most commonly involved fascial space by dental abscesses, [2] although other sources report it is the submandibular space. [1]
This space is subdivided into four smaller triangles by the digastricus above, and the superior belly of the omohyoideus. These smaller triangles are named: the muscular triangle; the carotid triangle; the submandibular triangle; the submental triangle
It is located between the lateral aspect of the mandible and the medial aspect of the masseter muscle and its investing fascia. The term is derived from sub-meaning "under" in Latin and masseteric which refers to the masseter muscle. The submasseteric space is one of the four compartments of the masticator space. [1]
