Using Cone-beam CT to Diagnose and Treat Otosclerosis

Cone-beam CT in the Diagnosis and Surgical Treatment of Otosclerosis.

Not applicable Interventional Rigshospitalet, Denmark · NCT05921578

This study is testing if using a special type of 3D imaging called Cone-beam CT can help doctors diagnose otosclerosis and plan surgery better than the usual methods for patients needing treatment.

What this trial studies

This study investigates the use of Cone-beam computed tomography (CBCT) for diagnosing otosclerosis and planning surgical treatment through stapedotomy. It aims to establish the diagnostic precision of CBCT, assess its role in clinical decision-making, and evaluate its effectiveness in pre-operative planning and post-operative follow-up. The study will involve randomization of patients into groups receiving CBCT-based planning versus standard treatment, with follow-up assessments at various intervals. A total of 300 patients will be included across different phases of the study.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years suspected of having otosclerosis who consent to participate.

Not a fit: Patients with a history of surgical treatment for otosclerosis or other middle-ear diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more accurate diagnoses and improved surgical outcomes for patients with otosclerosis.

How similar studies have performed: While the use of CBCT in otosclerosis is a relatively novel approach, similar imaging techniques have shown promise in other surgical fields.
