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.
Tissue reactions to glass ceramics in the middle ear
1981
The bioactive glass ceramic "Ceravital" was used to fashion prostheses for the replacement of various ossicles in the middle ear. They were tested in 70 rabbit ears, where they were accepted in osseous areas without formation of surrounding fibrous tissue. Histological examinations regularly showed an osseous bond with the surrounding bony tissue. Mucous membrane covered these ossicular chain prostheses and showed no evidence of inflammatory reactions. Glass ceramic implants were also used to reconstruct the ossicular chain and the posterior wall of the outer ear canal in 100 patients. The functional results were satisfactory in all cases.
Patologie rare dell'orecchio
2012
After fifty years of experience, mostly spent in ENT surgery at the University of Palermo, I have pleasure in presenting this Atlas of rare diseases of the ear, including clinical cases observed and documented during this long period from 1958 to 2006. We would prefer to divide all the case studies into three chapters: the outer ear, middle ear and inner ear.
