Three dimensional Computed tomography in oral and maxillofacial region

Reontgenographic evaluation of maxillofacial lesions is an important aspect in the evaluation of diseased patients. Standard radiography and conventional computed tomorgraphy produce two dimensional representations of anatomical structure under investigation. Recent developments in computer soft ware now enable the production of three dimensional images of complex anatomical structures from a series of conventional computed tomographic sections. Three dimensional computed tomogram has acceptables patial resolution, uniform geometric accuracy and flexibility in display and image manuplation. Thus, three dimensional computed tomogram provide the surgeon with here-to-fore unavailable global image of the facial anatomy. Three dimensional imaging allows the clinican to visualize spatial relationships that formerly had to conceptualized, a task, which sometimes proved to be rather difficult, and provide an opportunity for improved diagnosis and treatment planning. Now we introduce relatvely new modality that allows a spatial assessment of maxillofacial lesions utilizing three dimensional computed tomogram in the several cases.
