Introduction: Aim of the study is to evaluate the long-term results of ossiculoplasty with titanium prostheses.
Method: Since 1994 titanium PORPs or TORPs have been used in 240 out of our 503 tympanoplasties. Only 156 of them have completed the two-years follow-up and are included in this study. The PTA has been evaluated for each disease group one month, one and two years after surgery.
Results: Closure of air-bone-gap was significantly better in cases of patent stapes (titanium PORP) than in cases of absent suprastructure (titanium TORP). Functional results were better in cases of initial cholesteatoma surgery than in cases of recurrency of revision and in cases of preservation of the external canal wall (wall-up) than in cases of radical mastoidectomy (wall-down). Further, functional result could be maintained two years after surgery except in cases of wall-down tympanoplasty, where air conduction deteriorated slightly but significantly after two years. Overall cumulative survival of all titanium prostheses so far war 94% with prosthesis extrusion in 13 out of the 240 cases.
Conclusion: Titanium prostheses were found safe and reliable in long-term use for ossicular chain reconstruction with satisfactory result in closing the air-bone-gap especially is stapes was present. A better functional result could be achieved under preservation of canal wall.
