Summary
Titanium total prostheses (TORP) effectively reconstruct the ossicular chain, significantly improving hearing. Longer prostheses were linked to dislocation, but overall functional results remain favorable with long-term follow-up.
Area of Science:
- Otolaryngology
- Biomaterials Engineering
- Audiology
Background:
- Ossicular chain reconstruction is crucial for hearing restoration in middle ear pathologies.
- Titanium total ossicular replacement prostheses (TORP) offer a biocompatible option for complex reconstructions.
Purpose of the Study:
- To evaluate the efficacy and safety of titanium TORP for ossicular chain reconstruction.
- To assess long-term functional outcomes and identify factors associated with complications.
Main Methods:
- Retrospective analysis of 113 patients undergoing TORP reconstruction by a single surgeon (2006-2018).
- Follow-up until January 2020, including audiometric evaluation (air-bone gap).
- Analysis of prosthesis dislocation and correlation with prosthesis length.
Main Results:
- Significant mean air-bone gap improvement from 32.74 dB to 21.68 dB (p < 0.001).
- 50.44% of patients achieved a postoperative air-bone gap ≤ 20 dB.
- Prosthesis dislocation occurred in 12.39% of cases, associated with longer prosthesis length (p = 0.002).
Conclusions:
- Titanium TORP provides favorable functional outcomes in ossicular chain reconstruction with durable results.
- Prosthesis length is a critical factor to consider, as longer implants correlate with a higher risk of dislocation.
