[Imaging of mandibular malformations and deformities].

Mandibular deformities and malformations are quite various. They are mostly identified by clinical examination, but imaging is very useful for surgical planning. CT imaging is essential to evaluate patients with dystrophies such as fibrous dysplasia, neurofibromatosis, Gorlin syndrome and cherubism.

[Ectopic parotid gland in the mandible and masseter muscle].

An unusual case of double salivary ectopy of parotid gland is described into the masseter muscle and the mandibular ramus in a 45 year-old patient. He first was seen for a slow course tumefaction of the cheek. Imaging demonstrated the intramasseteric localization of the tumefaction and revealed a bone defect in the upper medial part of the mandibular ramus.
