Summary
This summary is machine-generated.

Monopolar electrosurgery (MES) is safe for patients with cochlear implants (CIs), with no adverse events or decreased hearing performance observed. Further guidance from manufacturers on MES use with CIs is recommended.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Medical Devices

Background:

  • Monopolar electrosurgery (MES) is a common surgical tool.
  • Cochlear implants (CIs) are increasingly used in patients with hearing loss.
  • The safety of MES in patients with CIs requires evaluation.

Purpose of the Study:

  • To assess the safety of monopolar electrosurgery (MES) in patients with cochlear implants (CIs).
  • To report outcomes of patients who underwent MES after CI implantation.

Main Methods:

  • Retrospective case series at a tertiary referral center.
  • Inclusion of patients with indwelling CIs who underwent surgery with documented MES use.
  • Analysis of audiology/otolaryngology documentation and speech recognition scores for adverse events and performance changes.

Main Results:

  • Thirty-five patients (10 bilateral CI) experienced 63 MES exposures (85.7% below clavicle).
  • No adverse events or decreased speech recognition (CNC, AzBio) were reported due to MES.
  • Most patients (91% CNC, 80% AzBio) maintained stable speech recognition scores.

Conclusions:

  • Monopolar electrosurgery (MES) use is safe in patients with cochlear implants (CIs).
  • No adverse events or performance decline were associated with MES exposure.
  • Manufacturers should provide clearer guidance on MES use with CIs to inform clinical decision-making.
