Role of perioperative antibiotic treatment in parotid gland surgery.

Overview

BACKGROUND: The value of routine prophylactic antibiotic treatment in parotid gland surgery remains undetermined. METHODS: A retrospective analysis was conducted of all patients who underwent parotidectomy at a university-affiliated tertiary care center between 1992 and 2009. Patients with insufficient data, specifically regarding postoperative complications and antibiotic administration were excluded from the study cohort. RESULTS: A total of 593 patients underwent parotidectomy during the study period. After exclusion, 464 patients were eligible for the study. Perioperative antibiotic treatment was given to 206 patients (45%). There was no difference in wound infection rates between patients who received perioperative antibiotic therapy and those who did not (p = .168). Multivariate analysis showed that female sex, neck dissection, and drain output >50 cc/24 hours were predictive of postoperative wound infection. CONCLUSION: Routine prophylactic antibiotic treatment has no role in parotid gland surgery. Perioperative antibiotic treatment is recommended for patients undergoing extensive parotid gland surgery with neck dissection. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1876-E1880, 2016.
