The muscles of mastication are enclosed in a layer of fascia, formed by cervical fascia ascending from the neck which divides at the inferior border of the mandible to envelope the area. Each masticator space also contains the sections of the mandibular division of the trigeminal nerve and the internal maxillary artery. [4]
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] Infections originating in either maxillary or mandibular teeth can spread into the buccal space, usually maxillary molars (most commonly) and premolars or mandibular ...
The boundaries of each submasseteric space are: the anterior margin of the masseter muscle anteriorly, the parotid gland posteriorly, [1] the zygomatic arch superiorly, [1] the inferior border of the mandible inferiorly, [1] the lateral surface of the mandibular ramus medially (the submasseteric space is superficial to the mandible), [1]
The communications of each pterygomandibular space are: [1] to the buccal space anteriorly; to the lateral pharyngeal space and peritonsillar space medially (around the medial pterygoid muscle). to the submasseteric space laterally (around the ramus of the mandible) to the parotid space posteriorly; to the deep temporal/infratemporal space ...
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 ]
Buccal means relating to the cheek. In humans, the region is innervated by the buccal nerve. The area between the inside of the cheek and the teeth and gums is called the vestibule or buccal pouch or buccal cavity and forms part of the mouth. In other animals, the cheeks may also be referred to as "jowls".
A buccal exostosis is an exostosis (bone prominence) on the buccal surface (cheek side) of the alveolar ridge of the maxilla or mandible. More commonly seen in the maxilla than the mandible, buccal exostoses are considered to be site specific. [ 2 ]
This space may be created by pathology, such as the spread of pus in an infection. Odontogenic infection of the mandibular anterior teeth may erode through the lingual cortical plate of the mandible. If the level at which the infection breaks out of the mandible is below the attachment of the mylohyoid, then it will spread into the submental ...
