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 ]
The buccal space (also termed the buccinator space) is a fascial space of the head and neck (sometimes also termed fascial tissue spaces or tissue spaces). It is a potential space in the cheek, and is paired on each side. The buccal space is superficial to the buccinator muscle and deep to the platysma muscle and the skin.
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]
The Stafne defect (also termed Stafne's idiopathic bone cavity, Stafne bone cavity, Stafne bone cyst (misnomer), lingual mandibular salivary gland depression, lingual mandibular cortical defect, latent bone cyst, or static bone cyst) is a depression of the mandible, most commonly located on the lingual surface (the side nearest the tongue).
In humans, the upper jaw includes the hard palate in the front of the mouth. [3] [4] The two maxillary bones are fused at the intermaxillary suture, forming the anterior nasal spine. This is similar to the mandible (lower jaw), which is also a fusion of two mandibular bones at the mandibular symphysis. The mandible is the movable part of the jaw.
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 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.
Acinic cell carcinoma is a malignant tumor representing 2% of all salivary tumors. 90% of the time found in the parotid gland, 10% intraorally on buccal mucosa or palate. The disease presents as a slow growing mass, associated with pain or tenderness in 50% of the cases. Often appears pseudoencapsulated.
