Official title: Short- and Medium-term Evaluation of Mastoid Filling Using Bioactive Glass"

Run by Centre Hospitalier Intercommunal Creteil · NCT05921643 · Data updated 2026-11-12

This study is testing if using a special type of glass to fill in the ear during cholesteatoma surgery helps patients heal better and prevents the problem from coming back.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with proven cholesteatoma requiring surgical intervention.

Probably not a fit

Patients with congenital cholesteatoma, previous surgeries for cholesteatoma, or those requiring an open surgical technique may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study involves adult patients with cholesteatoma who are undergoing surgery at the ENT department of Hospices Civils de Lyon. The closed surgical technique will be employed, where a filling material (GlassBONE™ or Bonalive™) is used to stabilize the cartilaginous fragment and prevent recurrence. Patients will be monitored post-operatively through a series of consultations at specified intervals to assess complications, healing, and quality of life. Imaging studies will also be conducted to evaluate the effectiveness of the filling material over time.

Why it matters

Potential benefit: If successful, this approach could improve surgical outcomes and reduce recurrence rates in cholesteatoma patients.

How similar studies have gone: While the use of bioactive glass in mastoid filling is a relatively novel approach, similar studies have shown promising results in other surgical applications.
