Background:
Cochlear implantation (CI) becomes more challenging when a programmable ventriculoperitoneal (VP) shunt is present on the same side of the head. We report a successful ipsilateral CI in a patient who suffered bilateral hearing loss after shunt surgery.
Method:
We describe the CI case of a 49-year-old woman with an implanted VP shunt device, and perform a retrospective review of the clinical, audiological, and radiological features, surgical techniques, and postoperative functional outcomes.
Findings:
During CI, the magnet in the core of internal antenna of the CI device was positioned approximately 8 cm from the shunt valve so that it would not be affected by the magnetic field of the programmable valve. Although the CI antenna tip and shunt catheter overlapped, we were very careful not to pull the shunt catheter out of position while the musculoperiosteal flap was elevated.
Conclusions:
The present result suggests that ipsilateral CI is an option for deaf adult patients who have a programmable shunt.
