Comparing mastoid obliteration with mastoidectomy for chronic ear infections

Mastoidectomy Followed by Mastoid Obliteration Using S53P4 Bioactive Glass Versus Mastoidectomy Alone for Chronic Suppurative Otitis Media: a Retrospective Comparative Study

Observational Diakonessenhuis, Utrecht · NCT06160505

This study is testing whether adding a special type of glass to ear surgery helps people with chronic ear infections have drier ears and need fewer follow-up surgeries.

What this trial studies

This observational study aims to compare the outcomes of mastoidectomy alone versus mastoidectomy combined with S53P4 bioactive glass obliteration in patients suffering from chronic suppurative otitis media (CSOM) with mastoid involvement. The study will analyze the frequency of dry ears and the need for revision surgeries in patients who underwent these procedures. By examining a cohort of patients operated on between 2010 and 2022, the researchers hope to determine the effectiveness of mastoid obliteration in improving patient outcomes. The study will utilize retrospective data to assess the long-term results of these surgical interventions.

Who should consider this trial

Good fit: Ideal candidates are patients diagnosed with chronic suppurative otitis media who have opacification of the mastoid air cells and have undergone mastoidectomy between 2010 and 2022.

Not a fit: Patients with middle ear cholesteatoma will not benefit from this study as they are excluded from participation.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options for patients with chronic ear infections, potentially reducing the need for additional surgeries.

How similar studies have performed: While the effectiveness of mastoid obliteration is gaining interest, this specific comparison has not been extensively tested in prior studies.
