BIOACTIVE GLASS CERAMIC

1983

The practicability of the bioactive glass ceramic Cernvitnl® in ear surgery was tested in animals. The histological findings are presented. Over the last 3 years implants of bioactive glass ceramic were used in humans. Prostheses for the total or partial reconstruction of the ossicular chain and the reconstruction of the bony wall of the outer ear canal were fashioned. We have conducted about 300 tympanoplasties and 60 total or partial reconstructions of the bony wall of the outer ear canal. The otoscopic and functional results were satisfactory.

Value and limits of computer-assisted tomography.

1980

Three years ago, at the VIIth International Congress of Radiology in Otorhinolaryngology, held in Copenhagen, the early impressive results of computer-assisted tomography (CAT) in otorhinolaryngology were presented. Since considerable technologic and diagnostic progress of CAT has taken place in the meantime, questions about the increase in CAT's value and the expansion of its limits are appropriate now. Computed and, in some cases, conventional tomograms of facial lesions are used in the discussion of these questions. There is no doubt of CAT's advance within the last few years; there are, however, limits of CAT to be emphasized: (a) coronal CAT might be uncomfortable (especially if the ga…
