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.
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.
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 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 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.
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.
Cementoma is an odontogenic tumor of cementum. It is usually observed as a benign spherical mass of hard tissue fused to the root of a tooth. [1] It is found most commonly in the mandible in the region of the lower molar teeth, occurring between the ages of 8 and 30 in both sexes with equal frequency . [1]
It is also known as a calcifying cystic odontogenic tumor, which is a proliferation of odontogenic epithelium and scattered nest of ghost cells and calcifications that may form the lining of a cyst, or present as a solid mass. [3] It can appear in any location in the oral cavity, but more commonly affects the anterior (front) mandible and ...
