Tympanoplasty with calcium phosphate.
A new approach to the problems of chronic middle ear disease using the hydroxyapatite prosthesis is described. Open surgery is preferred and, independent of the eradication, reconstruction is possible. The posterior canal wall is reconstructed with a canal wall prosthesis of porous hydroxyapatite. The middle ear chain defects are reconstructed with a prosthesis of dense hydroxyapatite. In the case of a cavity with a mobile bare footplate a total alloplastic middle ear of hydroxyapatite is used.
