title: [Benign pathology of the facial bones].
abstract: Benign pathology of the facial bones is divided into three groups: congenital, infectious and neoplastic. The knowledge of segmentation of the face into meridians is important for understanding malformations. Panoramic X-rays remain their diagnostic value. CT is able to define the exact location and contents of the tumor. Nowadays, MRI, sometimes gives information concerning the exact contents of tumors. The face is divided into meridians numbered from 0 to 7 and from 8 to 14 counting from the middle part to the external auditory neatus. Infection from dental caries may spread to the maxilla and the mandible and sometimes into masticator spaces. It can be responsible for maxillary fungal sinusitis in tumor. The main problem is not exact diagnosis but the exact location and extent of the disease in order to allow large surgical removal.
