Purpose:
The usefulness of topical antibiotic prophylaxis for routine oculofacial plastic surgery is not well established. Given concerns such as contact dermatitis, antibiotic resistance, and healthcare costs in conjunction with a low baseline rate of surgical site infections, the investigators sought to determine the frequency of infection with and without the use of topical antibiotic prophylaxis.
Design:
Randomized, controlled, unmasked clinical trial.
Participants:
Adult patients undergoing routine periocular surgery without prior history of periocular surgical site infection, need for perioperative oral or parenteral antibiotics, or allergy to all study medications.
Methods:
Participants were randomized before surgery to receive either antibiotic or placebo (mineral oil and petrolatum-based) ointment after surgery. Outcomes were measured at the first postoperative visit. The 2-tailed Fisher exact test was used to compare outcomes between groups.
Main Outcome Measures:
The primary outcome was the incidence of surgical site infections. The secondary outcomes included stratification of infections by patient risk characteristics, incidence of allergic contact dermatitis, and incidence of wound complications.
Results:
Four hundred one participants were enrolled and randomized, and 13 participants did not proceed with surgery or were lost to follow-up. High-risk features for infection were identified in 24% of the placebo group and 21% of the antibiotic group. Surgical site infections were more common in the placebo group (2.7% vs. 0.0%; P = 0.025). The rate of contact dermatitis was similar (0.5% vs. 0.5%; P = 1.00), as was the rate of wound dehiscence (2.7% vs. 3.5%; P = 0.77). Among the placebo group, the incidence of infections in the low- and high-risk participants was 2.9% and 2.2%, respectively. Infections were treated with oral or topical antibiotics and resolved without complication, except in 1 patient who required 2 subsequent surgeries to address the sequelae.
Conclusions:
After routine oculofacial plastic surgery, patients treated with a topical antibiotic ointment showed a lower risk of surgical site infection compared with patients treated with a nonantibiotic ointment.
Insights
Topical antibiotic ointment significantly reduced surgical site infections after oculofacial plastic surgery compared to placebo. This finding supports routine antibiotic prophylaxis despite concerns about resistance and costs.
Area of Science:
- Ophthalmology
- Plastic Surgery
- Infectious Disease
Background:
- The efficacy of topical antibiotic prophylaxis in routine oculofacial plastic surgery is not well-established.
- Concerns include contact dermatitis, antibiotic resistance, and healthcare costs, alongside a low baseline infection rate.
Purpose of the Study:
- To determine the frequency of surgical site infections with and without topical antibiotic prophylaxis.
- To evaluate secondary outcomes like contact dermatitis and wound complications.
Main Methods:
- A randomized, controlled trial involving adult patients undergoing periocular surgery.
- Participants received either antibiotic ointment or a placebo (mineral oil and petrolatum-based) post-surgery.
Main Results:
- Surgical site infections were significantly more common in the placebo group (2.7%) compared to the antibiotic group (0.0%; P=0.025).
- Rates of allergic contact dermatitis and wound dehiscence were similar between groups.
- Infections in the placebo group resolved without complication, except for one patient requiring further surgery.
Conclusions:
- Topical antibiotic ointment use after routine oculofacial plastic surgery is associated with a reduced risk of surgical site infection.
- This suggests a potential benefit of routine antibiotic prophylaxis in this surgical setting.
