NCT ID: NCT04448600 Completed - MRI Scans Clinical Trials

Bone Conduction Implant and MRI

BAHA-IRM
Start date: September 28, 2020
Phase:
Study type: Observational

Bone conduction implants (BCI) are widely used in cases of conductive/ mixed hearing loss or single side deafness when surgical treatment or air hearing aids are not feasible. There are two types of BCI, abutments (which pass through the skin) and magnets (where a subcutaneous magnet is coupled to an external magnet). Pathologies (such as cholesteatoma) leading to the insertion of this hearing implant often require prolonged MRI follow-up. However, both the abutment and the magnet are responsible for imaging artifacts that limit its interpretation. Frequency and extent of these artifacts remain unclear in the literature. In our experience, the magnet, due to its size and composition, produces larger artifacts than the abutment. The main objective of our study is to compare MRI artifacts for each of these device types (abutment and magnet).
