X线平片和AIM To analyze retrospectively the results of plain film, X ray tomography and CT scannings of zygomaxillo mandibular bone disease confirmed by operation and pathology and to discuss how to choose the appropriate method in enhancing the rate of correct diagnosis. METHODS Of the 20 patients, 4 zygomae and 3 maxillae were on water projections, 2 hard plate on lateral projection and 11 mandibulae on posterioanterior and lateral pojections and panoramic tomography. All patients were given CT axial, coronal scannings, 4 of whom were given injection of contrast medium. RESULTS X ray plain( n =3) showed negative (15%), 2 panoramic tomography showed negative (10%). CT scannings were good in displaying the position, sign, size and the neighboring structures of the disease. The rate of qualitative diagnosis was 85%. CONCLUSION X ray films are simple, economical and effective in diagnosing the bone disease. CT is good in displaying the early lesions but not good enough in qualitative diagnosis combination of the X ray films and CT scannings can enhance the rate of correct diagnosis.
