Summary
This study introduces an improved cartilage ossiculoplasty technique using perichondrium to reconstruct the ossicular mechanism. The method enhances graft stability and preserves cartilage integrity, leading to effective hearing reconstruction.
Area of Science:
- Otolaryngology
- Regenerative Medicine
- Biomaterials Science
Background:
- Cartilage autografts for ossicular reconstruction face challenges like graft displacement and loss of stiffness.
- Maintaining stable contact between grafts and ossicular remnants is crucial for successful outcomes.
Purpose of the Study:
- To present a modified cartilage ossiculoplasty technique addressing common complications.
- To evaluate the efficacy of this technique in achieving stable and functional ossicular reconstruction.
Main Methods:
- Utilized a cartilage graft with overlying perichondrium, incorporating a tunnel for ossicular remnant accommodation.
- Developed a perichondrial flap for secure graft anchorage to the stapes or malleus.
- Applied the technique in 115 patients with various ossicular defects.
Main Results:
- Achieved significant air-bone gap closure in a majority of patients: within 10 dB (14.8%), 15 dB (34.8%), and 20 dB (24.4%).
- 20.8% of cases showed air-bone gap closure within 25 dB.
- Longest follow-up extended to over 13 years, demonstrating sustained results.
Conclusions:
- The modified cartilage ossiculoplasty technique effectively overcomes common challenges.
- The method provides stable graft fixation, maintains cartilage nutrition, and improves hearing outcomes.
- This technique offers an easy and effective solution for ossicular reconstruction.
