Randomized Controlled Trial Clinical Trial
Antimicrobial prophylaxis for contaminated head and neck surgery.
The use of antibiotic prophylaxis in head and neck surgery is controversial. Most surgeons agree that when surgery requires entry into the aerodigestive tract through the skin the wound is by definition contaminated and antibiotic prophylaxis is indicated as it is in other contaminated wounds. There is no general agreement as to which antibiotic or combination of antibiotics to use or what the schedule of dosage administration should be. ⋯ Multifactorial analysis demonstrated that patients whose surgery included repair with a regional pectoral flap had a statistically significant increased chance of developing postoperative wound infection (P less than .05). Patients undergoing laryngectomy, with or without neck dissection, were at less risk of postoperative infection tham patients undergoing oropharyngeal resection (P less than .05). The preoperative existence of tracheotomy or prior radiation therapy had no demonstrable effect on the incidence of wound infection postoperatively in this study.
