[Application of osseous allografts in surgery of the middle ear. Authors' experience]

The authors describe an osseous allograft enabling reconstruction with or without filling of the middle ear cavities in suppurative chronic otitis. This filling material is a cryoconserved osseous allograft. It is saturated with an antibiotic sensitive to the germs responsible for otorrhea based on the data of the antibiotic sensitivity test and is thus adapted to each patient. The technique for preparing the material is described. This material was applied to 70 patients, including some who received the material over four years ago. The operation made it possible to stop the infection. The long-term check-ups show good tolerance of the material with, nevertheless, a certain amount of resorption in some cases.
