Purpose:
To evaluate the efficacy and safety of a titanium total prosthesis (TORP) in ossicular chain reconstruction.
Methods:
Retrospective analysis of 113 cases of total ossicular chain reconstruction performed by a single surgeon between 2006 and 2018. Follow-up lasted until January 2020. Participants were patients with chronic otitis media, cholesteatoma, or ossicular chain disruption.
Results:
Mean preoperative air-bone gap (± standard deviation) was 32.74 dB (± 11.62). Mean postoperative air-bone gap was 21.68 (± 11.29). Mean air-bone gap improvement was 11.06 dB (± 14.99) (p < 0.001). 57 cases had a post-operative air-bone gap smaller than or equal to 20 dB (50.44%). In four cases, prosthesis dislocation was observed (12.39%). Mean prosthesis length in this group was 5.29 mm (± 0.86) versus 4.36 mm (± 1.02) in cases without prosthesis dislocation (p = 0.002).
Conclusions:
Total ossicular reconstruction using a titanium prosthesis yields favorable functional results, also during prolonged follow-up. Prosthesis length was significantly longer in cases with prosthesis dislocation.
