Summary
Autologous cartilage grafts for type 3 tympanoplasty show better hearing results than prostheses. Stapes stabilizing cartilage graft (SSCG) offers a promising alternative for hearing reconstruction with fewer complications.
Area of Science:
- Otolaryngology
- Audiology
- Regenerative Medicine
Background:
- Type 3 tympanoplasty involves complex middle ear reconstruction.
- Evaluating hearing outcomes and complications is crucial for surgical success.
Purpose of the Study:
- To compare hearing results of type 3 tympanoplasty using autologous cartilage grafts versus prostheses.
- To assess the efficacy and safety of stapes stabilizing cartilage graft (SSCG) compared to Plastipore partial ossicular replacement prosthesis (PPORP).
Main Methods:
- Retrospective study comparing SSCG and PPORP for hearing reconstruction in type 3 tympanoplasty.
- Postoperative audiological tests performed at least 6 months post-surgery.
- Assessment of hearing thresholds, air-bone gap (ABG), and complications.
Main Results:
- SSCG group showed a statistically significant improvement in air conduction threshold compared to PPORP (p=0.022).
- No complications were reported in the SSCG group, while PPORP had cases of vertigo and one extrusion.
- While ABG changes were greater in SSCG, the difference was not statistically significant.
Conclusions:
- Stapes stabilizing cartilage graft (SSCG) demonstrates superior hearing outcomes compared to PPORP.
- SSCG is a viable and safe alternative for hearing reconstruction in type 3 tympanoplasty.
