Factors affecting wound infection rates in head and neck surgery.
OBJECTIVE
This study was planned with 2 goals in mind: to evaluate the efficacy of prolonged and 1-day antibiotic regimens for prophylaxis and to evaluate the effect of various factors such as neck dissection, localization and stage of tumor, type of laryngectomy, and history of prior radiotherapy, tracheotomy, and diabetes mellitus on postoperative wound infection rates.


METHODS
In this study, 408 head and neck procedures (201 clean and 207 clean-contaminated) performed at our institution were retrospectively reviewed.


RESULTS
Prolonged and 1-day antibiotic regimens for both clean and clean-contaminated procedures were similar in efficacy (7% vs 3% for clean procedures [P = 0.165] and 30% vs 28% for clean-contaminated procedures [P = 0.777]). The wound infection rate was higher (13%) after clean radical neck dissections versus other clean procedures (1%) (P = 0.001). For clean-contaminated procedures, factors affecting postoperative wound infection rates were performance of bilateral neck dissections (P = 0.014), disease stage (P = 0.002), type of laryngectomy (P = 0.002), and history of prior tracheotomy (P = 0.006).
