[Computer-tomography of the facial bones (part I). Demonstration of various structures and deeply placed regions (author's transl)].
Conventional diagnosis of facial structures by endoscopy and conventional tomography often meets with the following difficulties: 1. Deeply placed areas cannot be seen, or are only partly visible by endoscopy. 2. Conventional tomography produces a two-dimensional section of a three dimensional object which may be confused by out of focus tomographic shadows. Our first attempts at computer tomographic examination of the facial structures in 41 patients have shown that this technique, working with parallel rays and without confusing shadows, is able to provide an accurate morphological demonstration of various structures and organs in the facial region.
