Summary
Many surgeons are unaware of cochlear implant safety guidelines regarding diathermy use. This knowledge gap poses a risk to patients with cochlear implants, highlighting the need for increased awareness of safe surgical practices.
Area of Science:
- Otorhinolaryngology
- Neurosurgery
- Medical Device Safety
Background:
- Cochlear implants (CIs) are electrical devices for profound deafness, vulnerable to electromagnetic interference.
- Surgical diathermy poses a risk of damage to CIs due to electrical energy.
- Existing guidelines restrict diathermy use near CIs to prevent harm.
Purpose of the Study:
- To assess surgeon awareness of diathermy safety guidelines for cochlear implant patients.
- To identify deficits in knowledge that could compromise patient safety.
Main Methods:
- A questionnaire was distributed to 36 head and neck surgeons.
- 35 surgeons responded regarding their knowledge of diathermy safety with CIs.
Main Results:
- 77% of surgeons were unaware of published diathermy safety guidelines for CIs.
- 11% incorrectly believed monopolar diathermy was safe above the clavicles.
- 49% believed bipolar diathermy had no usage restrictions near CIs.
Conclusions:
- A significant knowledge deficit exists regarding safe diathermy practices in cochlear implant patients.
- This lack of awareness threatens patient safety.
- Increased awareness of guidelines is crucial for the surgical community.
