[Serious jaw osteolytic lesions].

Among oral and maxillofacial diseases, the maxillary osteolytic lesions constitute a rich and investigated field to define the more appropriate diagnosis and treatment. In the maxillary region, the same tumors of the other bones (osteogenic sarcoma, chondroma, etc.) cause found together with tumors and dysembryoplasias connected with the teeth development (ameloblastoma, odontoma, odontogenic myxoma, etc.). Moreover in the medullary spaces of the bones, there are reticular and hematopoietic cells that are connected with different diseases (leucemia, myeloma, lymphoma, etc.). What's more, due to the possible presence of pseudotumors (fibrous dysplasia, giant cell tumor, etc.) and metastases of tumors of other regions (breast, lung, prostate gland, etc.), the diagnosis of this disease could be difficult. In this paper the more important pictures of this disease, that due to its recurrence or malignity needs an accurate diagnosis by imaging like CT, CT-3D, MR, etc, are analyzed. The more suitable surgical approach is presented, according to the forms of the disease.
