Description:
PURPOSEThis study evaluated long‐term results in patients who had ossicular reconstruction with a Goldenberg hydroxylapatite implant.METHODSA total of 233 patients underwent implantation; of these, 77 had 5‐year or longer follow‐up and are the subjects of this study of long‐term hearing results. All 233 patients were included for analysis of extrusion rate and postoperative otorrhea.RESULTSThe hearing success rate at long‐term follow‐up was 56.8%; the mean air‐bone gap was 21.1 dB. Prosthesis extrusion occurred in 5.29% of the 233 patients, and visible slippage occurred in 7.7%. Overall, 50.6% of patients met the criteria for successful hearing, which included no extrusion and a dry ear. Better hearing before surgery and presence of the malleus long process were factors associated with a successful hearing result, as was tympanoplasty alone and canal wall up tympanomastoidectomy.CONCLUSIONHydroxylapatite hybrid prostheses provide stable hearing results over time with low extrusion and a dry ear overall.
