The mandibular fossa, also known as the glenoid fossa in some dental literature, is the depression in the temporal bone that articulates with the mandible.
It affects the mandible in 61% of cases, the maxilla in 24% of cases, and soft tissue in 16% of cases. In the majority of cases, the tumor originated in the breast, lung, kidney, colon, or prostate. The original tumor usually spreads to the jaws through Batson's paravertebral plexus. Teeth can become mobile and paresthesia can occur.
The condyle of the mandible articulates with the temporal bone in the mandibular fossa. The mandibular fossa is a concave depression in the squamous portion of the temporal bone. These two bones are actually separated by an articular disc, which divides the joint into two distinct compartments.
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).
The temporomandibular joints are the dual articulation of the mandible with the skull. Each TMJ is classed as a "ginglymoarthrodial" joint since it is both a ginglymus (hinging joint) and an arthrodial (sliding) joint, [42] and involves the condylar process of the mandible below, and the articular fossa (or glenoid fossa) of the temporal bone ...
The tumor is benign, but without intervention it can result in severe disfigurement of the jaw and of the facial skeleton. It is commonly found in the mandible and the maxilla but it is less commonly found in the maxilla. The tumor can be found between the premolars and the molars.
Moderately advanced local disease, tumor >4 cm with DOI* >10mm or tumor invades adjacent structures only (cortical bone of the mandible or maxilla (excluding superficial erosion of tooth socket alone in gingival tumors) or involves the maxillary sinus or skin of the face) T4b Very advanced local disease.
Central giant-cell granuloma (CGCG) is a localised benign condition of the jaws.It is twice as common in females and is more likely to occur before age 30. Central giant-cell granulomas are more common in the anterior mandible, often crossing the midline and causing painless swellings.
