[Results with a new type ossicular prostheses mixed bone morphogenetic protein and hydroxyapatite].
OBJECTIVE
To evaluate the results in patients who had ossicular chain reconstruction with a new type ossicular prostheses mixed bone morphogenetic protein and hydroxyapatite.


METHODS
Analyze The effect of ossiculoplasty were analyzed in 59 cases. Ossiculoplasty using HA-BMP prostheses was performed in 26 ears,PORP was performed in 19 ears, TORP was performed in 7 ears.


RESULTS
The hearing success rate was 92.3% of 26 ears and no extrusion were found in HA-BMP group. There was a significant difference in mean postoperative air-bone gap between HA-BMP prostheses and autograft bone.


CONCLUSIONS
The new type HA-BMP prostheses can provide stable hearing results with high success rate over time.
