Summary
Titanium clip partial ossiculoplasty using the CliP Partial FlexiBAL® (CPF) prosthesis offers superior audiologic outcomes compared to the CliP® Partial Prosthesis Dresden Type (CPPDT). The CPF prosthesis demonstrates better adaptability for improved hearing results in tympanoplasty.
Area of Science:
- Otolaryngology
- Biomaterials in Surgery
- Audiology
Background:
- Ossiculoplasty is a surgical procedure to reconstruct the middle ear ossicular chain.
- Titanium prostheses are commonly used in partial ossiculoplasty.
- Evaluating prosthesis performance is crucial for optimizing surgical outcomes.
Purpose of the Study:
- To compare the audiometric outcomes and extrusion rates of two types of titanium partial clip prostheses.
- To review existing literature on titanium partial clip ossiculoplasty.
- To identify factors influencing the success of ossicular reconstruction.
Main Methods:
- Retrospective analysis of 274 patients undergoing primary partial ossiculoplasty.
- Comparison between CliP® Partial Prosthesis Dresden Type (CPPDT) and CliP Partial FlexiBAL® (CPF) prostheses.
- Evaluation of preoperative and postoperative air-bone gap (ABG) and prosthesis extrusion rates.
Main Results:
- Postoperative ABG significantly improved (15.7 dB vs 22.7 dB preoperative), with 76.6% achieving ABG ≤ 20 dB.
- The CPF group showed significantly better audiological outcomes than the CPPDT group.
- Extrusion rates were 1.38% for CPF and 8.62% for CPPDT (p=0.012).
- Normal middle ear aeration correlated with better audiological results.
Conclusions:
- Titanium clip partial ossiculoplasty provides satisfactory audiologic outcomes in tympanoplasty.
- The CPF prosthesis offers superior adaptability, leading to better hearing results, especially with middle ear aeration issues.
- CPF is a reliable option for ossicular reconstruction, enhancing functional recovery.
