Summary
Intraoperative imaging for cochlear implant electrode placement varies globally. Surgeons in North America favor X-rays, while Europe and Asia use less imaging, highlighting the need for standardized cochlear implantation practices.
Area of Science:
- Otolaryngology
- Neurosurgery
- Medical Imaging
Background:
- Cochlear implantation requires precise electrode placement for optimal hearing restoration.
- Intraoperative confirmation of electrode position is crucial but practice patterns are not well-defined globally.
Purpose of the Study:
- To characterize worldwide practice patterns regarding intraoperative imaging and functional confirmation of cochlear implant electrode location.
Main Methods:
- A global cross-sectional survey was conducted among otolaryngologists performing cochlear implantation.
- Data were collected from March 1 to May 6, 2023, with 97 participants from various continents.
Main Results:
- North American surgeons utilize intraoperative X-rays more frequently than those in Europe and Asia.
- European and Asian surgeons more commonly use no intraoperative imaging compared to North American counterparts.
- Device selection varies by region, with MED-EL devices more common in Europe/Asia and Cochlear Corporation devices in North America. Device type correlated with imaging modality used.
Conclusions:
- Significant global variation exists in intraoperative practices for verifying cochlear implant electrode positioning.
- Developing standardized practice guidelines could enhance the standard of care for cochlear implantation worldwide.
