Materials and methods. The study included 87 drug addicted patients with a diagnosis of toxic phosphorus jaw osteonecrosis. In the preoperative period all patients underwent full clinical and radiological examination, including clinical examination, X-ray examinations (orthopantomography, skull x-ray, multislice computed tomography). During the analysis of preoperative radiology examination data following parameters were evaluated: the bone structure of the jaws, the preservation of the mandibular nerve channels, a condition of the temporomandibular joints, paranasal sinuses and nasal cavity, involvement of other bones of the facial and brain skull. All patients underwent surgical treatment such as total or partial resection of the jaw. X-ray studies were repeated in the postoperative period, which included orthopantomography and multislice computed tomography. Results. According to the carried out radiology examination at the preoperative stage, depending on the localization of jaw phosphorous necrosis all patients (n=87; 100,0 %) were divided into three groups: with osteonecrosis of the mandible (n=40; 46,0 %), oste-onecrosis of the maxilla (n=18; 21,0 %) and concomitant osteonecrosis (mandible and maxil-la) (n=29; 33,0 %). According to the analysis the diagnostic efficiency of radiological methods in the evaluation of patients with jaws phosphorus osteonecrosis was determined. Conclusion. Thus the diagnostic efficiency parameters for multislice computed to-mography were: the sensitivity – 93,1%, the specificity – 98,6%, the accuracy – 97,8%, for orthopantomography: the sensitivity – 66,7%, the specificity – 72,2%, the accuracy – 69,3%, for skull X-ray: the sensitivity – 72,4%, the specificity – 79,8%, the accuracy – 74,8%.

Keywords: osteonecrosis, multislice computed tomography, orthopantomography, desomorphine.
