    Computed tomography (CT) effectively assesses cochlear implant electrode position after surgery, identifying malposition in one patient. Further experience will refine CT

    Area of Science:

    • Radiology
    • Otolaryngology
    • Neurosurgery

    Background:

    • Cochlear implantation is a complex surgical procedure.
    • Accurate electrode placement is crucial for optimal hearing outcomes.
    • Postoperative imaging is essential for verifying device integrity and position.

    Purpose of the Study:

    • To evaluate the utility of computed tomographic (CT) examinations in assessing cochlear implant electrode position.
    • To correlate imaging findings with audiometric results.
    • To identify potential imaging pitfalls in the postoperative period.

    Main Methods:

    • Seven patients undergoing cochlear implant surgery were included.
    • Pre- and postimplantation CT scans were performed.
    • A specialized "transpetrous" projection was utilized for detailed imaging of the cochlea.

    Main Results:

    • Preimplantation CT provided excellent visualization of petrous anatomy and identified one pre-existing abnormality.
    • Postimplantation CT accurately assessed electrode placement in all seven patients.
    • One case of active electrode malposition was detected and correlated with audiometric findings.

    Conclusions:

    • Computed tomography is a valuable tool for evaluating cochlear implant electrode position postoperatively.
    • CT can identify electrode malposition, aiding in clinical management.
    • Awareness of potential imaging artifacts, such as partial-volume averaging, is important for accurate interpretation.
