What this trial studies

This observational study investigates the effectiveness of S53P4 bioactive glass for secondary obliteration of old radical mastoid cavities. The procedure aims to reconstruct the posterior wall of the external auditory canal to reduce postoperative complications such as otorrhea, pain, and dizziness. The study will evaluate outcomes based on the Merchant grading scale for postoperative otorrhea, focusing on the material's volume retention and antibacterial properties. Participants will have undergone canal wall down surgeries between 2011 and 2022.

Who should consider this trial

Good fit: Ideal candidates are individuals who have had canal wall down surgeries resulting in old mastoid cavities.

Not a fit: Patients with middle ear cholesteatoma or those who have previously undergone obliteration will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce postoperative complications for patients with old mastoid cavities.

How similar studies have performed: While this approach is innovative, similar studies using bioactive materials for surgical reconstruction have shown promise, suggesting potential for success.
