[Anatomy of the temporal bone assessed by high resolution computed tomography, endoscopy and microscopy]

Visualization of all anatomical structures inside the middle ear is indispensable to perform surgical treatment. The aim of this study was the attempt to show landmarks of the middle ear employing different imaging techniques. The value of high resolution CT with 1 milimeter layers, Hopkins endoscopy and operating microscope with 16 time magnification were assessed. The primary evaluation by the CT scans were made and directed the further efforts. Endoscopy and microscopy were performed as a next diagnostic steps and allowed for tool-eye visualization of all important anatomical structures in the middle ear. The anatomy and pathology of tympanic cavity assessed by three different technics used together occurred to be much more detailed. The results were complementary and useful.
