Clindamycin/cefonicid in head and neck oncologic surgery: one-day prophylaxis is as effective as a three-day schedule.

The aim of our study was to evaluate the optimal duration of antibiotic prophylaxis in major oncologic surgery of the head and neck using a novel broad spectrum drug combination: clindamycin and cefonicid. A prospective randomized study was carried out on 126 evaluable patients undergoing clean-contaminated (skin to mucosa) surgery for cancer of larynx, pharynx or oral cavity. Cases at high surgical risk (because of need of pedicled or microvascular free flaps reconstruction), were excluded from the study. Within 20 days after surgery, only one case of wound infection was recorded among the 62 patients treated with the one-day schedule, versus three cases registered among the 64 subjects receiving three-day chemoprophylaxis. Episodes of systemic infections and eventual wound complications occurring in the first 20 days after surgery have also been recorded. The role of potential risk factors for postoperative complications has been evaluated. According to our findings, a three-day antibiotic regimen is not more effective than a short-term (one-day) schedule in preventing wound or systemic infection in clean-contaminated head and neck cancer surgery without flap reconstruction.
