Summary
Cartilage grafts offer a reliable, cost-effective solution for ossicular chain reconstruction in type III tympanoplasty, providing significant long-term hearing improvement with minimal complications.
Area of Science:
- Otolaryngology
- Regenerative Medicine
- Biomaterials Science
Context:
- Type III tympanoplasty aims to restore hearing by reconstructing the ossicular chain.
- Cartilage is increasingly explored as a biocompatible graft material for middle ear reconstruction.
- Evaluating long-term functional outcomes of cartilage grafts is crucial for surgical success.
Purpose:
- To assess the long-term functional success rate of cartilage as graft material in type III tympanoplasty.
- To analyze hearing outcomes, specifically air-bone gap closure, and complication rates.
- To compare the efficacy of open versus closed surgical techniques using cartilage grafts.
Summary:
- A retrospective review of 79 patients undergoing type III tympanoplasty with cartilage grafts (74% single-stage) showed a mean follow-up of 54 months.
- 92.2% of cases achieved post-operative air-bone gap closure ≤ 30 dB, with a mean gain of 9.72 dB.
- While hearing improvement is substantial and long-lasting, a gradual decline was observed; closed techniques showed slightly better outcomes.
Impact:
- Cartilage is a readily available, cost-effective, and reliable graft material for ossicular chain reconstruction.
- It demonstrates good biocompatibility, low extrusion risk, and long-term functional viability.
- Cartilage presents a viable option for functional restoration in middle ear surgery, particularly when placed on the stapes capitulum.
