Abstract

Insights

Evidence is insufficient to confirm the benefits of prophylactic antibiotics for cochlear implant (CI) surgery. While infection rates are low, patient-specific risk-benefit assessments are crucial for antibiotic decisions.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Infectious Disease

Background:

  • Previous reviews found no benefit of prophylactic antibiotics in general ear surgery.
  • These reviews did not specifically evaluate cochlear implant (CI) surgery.

Purpose of the Study:

  • To systematically review the effects of perioperative antibiotics on infection risk and complications in CI surgery.

Main Methods:

  • Searched multiple databases (PubMed, EMBASE, Medline, CINAHL, Cochrane) from inception to March 2015.
  • Included studies on perioperative antibiotic use in CI surgery, assessing infection, meningitis, implant extrusion, and adverse effects.
  • Two independent evaluators reviewed all identified abstracts and articles.

Main Results:

  • Only three studies met inclusion criteria; all were of low quality, with no randomized trials.
  • Heterogeneous antibiotic regimens and outcome measures were reported, with limited detailed information.
  • Overall infection rates were low (3%-4.5%), and single-dose prophylaxis showed a 1% complication rate in two studies.

Conclusions:

  • Insufficient evidence exists to definitively establish the role of perioperative antibiotics in CI surgery.
  • Low reported infection rates suggest caution, emphasizing individualized risk-benefit analysis for antibiotic use.
