Hydroxyapatite-bone morphogenetic protein ossicular prosthesis versus allogeneic cartilage ossicular prosthesis for ossicular chain damage / 中国组织工程研究

ABSTRACT

BACKGROUND:There is a great dispute on the choice of repair materials for ossicular chain damage. OBJECTIVE:To explore the effects of new hydroxyapatite-bone morphogenetic protein ossicular prosthesis versus al ogeneic cartilage ossicular prosthesis in patients with ossicular chain damage. METHODS:Sixty patients with chronic otitis media were equal y assigned into a control group and a test group. Two groups of patients underwent tympanoplasty and ossicular chain reconstruction with al ogeneic cartilage ossicular prosthesis or hydroxyapatite-bone morphogenetic protein ossicular prosthesis, respectively. Twelve months after surgery, fol ow-up results were compared between two groups. RESULTS AND CONCLUSION:Air conduction value and air-bone gap value were both improved significantly in the two groups after surgery (P Subject headings:Tympanoplasty;Otitis Media;Bone Morphogenetic Proteins;Tissue Engineering
