Withholding post-operative antibiotics following reconstructive surgery necessitating skin grafting for defects of the face or nose.

All patients will receive peri-operative antibiotics per standard practice. This consists of a single dose of cefazolin or, in penicillin allergic patients, clindamycin administered at the time of anesthesia administration prior to the surgical incision. In the cohort randomized to receive post-operative antibiotics, the first choice intervention will be oral cephalexin (500 mg, three times daily or four times daily, for one week). In patients who are penicillin or cephalosporin allergic, we will prescribe clindamycin (300 mg, three times daily or four times daily, for one week).

In patients who are penicillin or cephalosporin allergic, we will prescribe clindamycin (300 mg, three times daily or four times daily, for one week). Patients will be followed up within 2 to 6 weeks of surgery and outcome measures assessed. Patients will, again, be seen at 6 months and 1 year post-operatively for outcome assessment.

The primary outcomes will be graft failure rate where failure is defined as any tissue loss extending beyond the epithelium.

The secondary outcomes include the percentage surface area of graft failure, the incidence of post-operative adjunctive procedures related to graft cosmesis and the incidence of revision surgery resulting from graft failure.
