Implication

Cadaveric study reveals clinical computed tomography accurately determines cochlear implant electrode position, indicating reliable noninvasive postoperative assessment.

Key Points

To evaluate the efficacy of clinical computed tomographic (CT) imaging in verifying postoperative electrode array placement in cochlear implant patients.
Nine fresh cadaver heads underwent clinical CT scanning before and after bilateral cochlear implant electrode array insertion.
Extracted temporal bones were analyzed with micro-CT and sectioned for histologic examination by 3 blinded observers to classify electrode position in the scala tympani, scala vestibuli, or intermediate positions.
Micro-CT verification demonstrated a 97% agreement with clinical CT estimates of electrode array placement across all specimens.
Histologic analysis confirmed clinical CT localization of individual electrodes with 95% agreement.
