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 allogeneic cartilage ossicular prosthesis in patients with ossicular chain damage.
METHODS: Sixty patients with chronic otitis media were equally assigned into a control group and a test group. Two groups of patients underwent tympanoplasty and ossicular chain reconstruction with allogeneic cartilage ossicular prosthesis or hydroxyapatite-bone morphogenetic protein ossicular prosthesis, respectively. Twelve months after surgery, follow-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 < 0.05), and especially, the postoperative air conduction value was better in the test group than the control group (P < 0.05). Implant detachment was found in three cases of the control group, whereas did not occur in the test group. Improved hearing was found in 28 cases in the test group with an improvement rate of 93% and 25 cases in the control group with an improvement rate of 83%. There was a significant difference in the hearing improvement between the two groups (P < 0.05). Overall, two kinds of prostheses can share similar effects on the ossicular chain repair.
