Area of Science:

Radiology
Otolaryngology
Medical Imaging

Background:

Electrophysiological testing has advanced, but imaging remains the gold standard for assessing cochlear implant (CI) placement.
Cone beam computed tomography (CBCT) offers optimal visualization, while modified Stenver radiographs are a more accessible alternative.
Debate exists regarding routine imaging for uncomplicated CI cases, increasing the radiologist's role in identifying anomalies.

Observation:

The positioning of the CI electrode array within the cochlea is the primary focus of radiologic assessment.
Key elements include checking for tip roll-over or kinking of the electrode array.
Evaluating the depth of electrode insertion is also critical.

Findings:

Abnormal anatomy or surgical errors necessitate careful radiologic evaluation.
Tip deformities (roll-over, kinking) and insertion depth are independent predictors of hearing outcomes.
These findings can indicate the need for revision surgery.

Implications:

Accurate radiologic assessment is vital for optimizing hearing results after cochlear implantation.
Identifying malpositioning early can prevent suboptimal outcomes and guide surgical revision.
Standardized imaging protocols are essential for consistent evaluation of cochlear implant placement.
