Summary
A rare cochlear implant complication occurred when the electrode array entered the superior semicircular canal. Intra-operative radiological assessment is crucial for confirming correct cochlear implant electrode placement.
Area of Science:
- Otolaryngology
- Neurosurgery
- Medical Imaging
Background:
- Cochlear implantation is a common treatment for profound sensorineural deafness.
- Accurate electrode array placement is critical for successful cochlear implant outcomes.
Observation:
- A case of electrode array misplacement into the superior semicircular canal during cochlear implantation is presented.
- Intra-operative neural response imaging showed some function, despite the malposition.
Findings:
- Radiological assessment revealed the electrode array had entered the superior semicircular canal in the right ear.
- Neural response imaging indicated some neural activity, but its interpretation requires caution.
Implications:
- Intra-operative monitoring, including neural response imaging, is insufficient alone for confirming correct electrode placement.
- Mandatory intra-operative radiological assessment is essential to prevent rare cochlear implant complications like this.
