Objective:
The objective of this study to evaluate antibiotic prophylaxis options for cochlear implant surgery. Does long-term antibiotic prophylaxis have any advantage over a single perioperative dose in preventing postoperative infection?
Study Design:
We conducted a retrospective case review.
Patients:
A total of 292 adult and pediatric patients who underwent cochlear implantation during a 15-year period (1988-2003) were reviewed.
Main Outcome Measure:
Minor and major postoperative wound infections in first 4 weeks.
Results:
There were four major and eight minor complication among 292 patients (complication rate 4.1%). The infection rate was higher in patients who had either C incision (11.1%) or extended endaural incision (7.5%) and in patients with a preexisting medical condition. The infection rate was also higher in patients who had long-term antibiotics (5.6% and 13% in the 5-d and 7-d regimes) compared with short-term (single-dose) group.
Conclusion:
Long-term antibiotic prophylaxis did not have any advantage over single perioperative dose. Predisposing medical conditions and extensive surgical incisions were associated with a greater severity of infections and higher risk of wound complications.
