Cone Beam CT Versus Multislice CT in the Postoperative Assessment of Cochlear Implantation

Cone Beam CT Versus Multislice CT: Radiologic Diagnostic Agreement in the Postoperative Assessment of Cochlear Implantation

Objective: To evaluate the diagnostic concordance between multislice computed tomography (MSCT) and cone beam computed tomography (CBCT) in the early postoperative assessment of patients after cochlear implantation.

Study Design: Prospective, randomized, single-center, interventional, pilot study on the diagnostic performance of a medical device.

Setting: Tertiary referral center. Patients: Patients aged over 18 years requiring a CT scan after cochlear implant surgery.

Interventions: Nine patients were implanted with electrode arrays from three different manufacturers, including one bilateral. High-resolution MSCT and CBCT were then performed, and 2 experienced radiologists blinded to the imaging modality evaluated the randomized images, twice.

Inclusion Criteria:

• CI surgery for severe to profound bilateral deafness
• affiliated with the French health insurance

Exclusion Criteria:

• pregnancy
• Patients weighing more than 160 kg
