Abstract

Abstract : Objective: Although it is known that the airway has bacterial contamination that seeds the surgical site during microlaryngeal surgery, literature on the use of postoperative antibiotics is lacking. We performed a retrospective analysis of open phonosurgical and phonomicrosurgical cases at a single institution to assess whether use of postoperative antibiotics impacts the incidence of surgical site infections (SSI). Methods: In this retrospective cohort study, we reviewed 228 phonomicrosurgery and 53 open phonosurgery cases performed for benign diseases. Surgeries were performed by two laryngologists between February 2016 and August 2018. The surgeons differ in their postoperative antibiotic regimens: no antibiotics versus a 5‐ to 7‐day postoperative course. Data collected include demographics, medical comorbidities, type of benign laryngeal disease, and surgical procedure. The primary outcome measure was postoperative infection, defined as the patient requiring a new prescription for antibiotics, an extended course of antibiotics, or any mention of infection at follow‐up/emergency visits within the first month postoperatively. Results: The overall rate of SSI was 3.1% and 0% for phonomicrosurgery and open phonosurgery cases, respectively. For phonomicrosurgery, there was no difference in the rate of SSI for patients who received or did not receive antibiotics perioperatively: 2.9% versus 3.2% ( P = 0.99). Similarly, there was no difference in the infection rate for open phonosurgical cases. Conclusion: Infection rates after endoscopic and open phonosurgery are low. In this study, we found no evidence to suggest a protective effect associated with postoperative use of antibiotics. Level of Evidence: 4 Laryngoscope, 130:1128–1131, 2020
