Summary
A single preoperative antibiotic dose is sufficient for septorhinoplasty infection prophylaxis. This approach reduces side effects and healthcare costs compared to longer antibiotic regimens, addressing antibiotic resistance concerns.
Area of Science:
- Otolaryngology
- Surgical Infection Prevention
- Pharmacoeconomics
Background:
- Routine antibiotic use in septorhinoplasty lacks evidence, contributing to antibiotic resistance and increased healthcare costs.
- The study addresses the need for evidence-based guidelines on antibiotic prophylaxis in this common surgical procedure.
Purpose of the Study:
- To evaluate the efficacy and safety of single-dose versus multi-dose antibiotic prophylaxis in septorhinoplasty.
- To determine the impact on postoperative infection rates, side effects, and costs.
Main Methods:
- A prospective, randomized, single-blind study involving 200 patients undergoing septorhinoplasty.
- Group 1: Preoperative single-shot antibiotics. Group 2: Preoperative single-shot plus 7-day postoperative oral antibiotics.
Main Results:
- No statistically significant difference in infection rates between the groups (3% in combined group vs. 0% in single-dose group).
- Significantly higher incidence of antibiotic-induced side effects in the combined treatment group (29% vs. 2%).
- Combined treatment group incurred significantly higher antibiotic and side effect management costs (93.45 AUD vs. 14.50 AUD).
Conclusions:
- A single preoperative antibiotic dose is adequate for infection prophylaxis in septorhinoplasty with autologous cartilage grafting.
- Eliminating postoperative antibiotics reduces costs and adverse effects, supporting antimicrobial stewardship.
