Summary
Hyaluronic acid showed no significant difference in middle ear healing or hearing outcomes compared to standard tympanoplasty techniques. Further research is needed to explore its long-term efficacy in these procedures.
Area of Science:
- Otolaryngology
- Biomaterials Science
Background:
- Tympanoplasty involves surgical reconstruction of the eardrum and middle ear.
- Hyaluronic acid is a biomaterial with potential applications in tissue healing and regeneration.
Purpose of the Study:
- To investigate the efficacy of hyaluronic acid in tympanoplasty.
- To compare healing quality and hearing results between hyaluronic acid groups and a control group.
Main Methods:
- Multicenter, randomized, prospective, patient-blinded study.
- 117 patients underwent myringoplasty, myringoplasty with ossiculoplasty, or ossiculoplasty alone.
- Patients were divided into two groups using 1% or 1.9% hyaluronic acid and a control group without hyaluronic acid.
Main Results:
- No statistically significant differences in middle ear healing or tympanic membrane recovery were observed between groups.
- Hearing results were similar across all three groups (hyaluronic acid vs. control).
- No gelatinous sponge was left in the middle ear in hyaluronic acid groups, unlike the control group.
Conclusions:
- Hyaluronic acid, at tested concentrations, did not demonstrate a significant advantage over standard tympanoplasty techniques regarding short-term healing and hearing outcomes.
- The study suggests hyaluronic acid may not offer immediate benefits in tympanoplasty.
- Long-term results were not assessed, leaving potential for future investigation into hyaluronic acid's role.
