Abstract

Perioperative management of advanced osteoradionecrosis of the head and neck requiring free flap (FF) reconstruction varies. Our objectives included assessment of practice patterns and outcomes. Multi-institutional, retrospective review of FF reconstruction for head and neck osteoradionecrosis (n=260). Administration of preoperative antibiotics did not correlate with reduction in postoperative complications. Preoperative alcohol use correlated with higher rates of hardware exposure (p=0.03) and 30-day readmission (p=0.04). Patients with FF compromise had higher TSH (p=0.04) and lower albumin levels (p=0.005). Prealbumin levels were lower in patients who required neck washouts (p=0.02) or a second FF (p=0.03). TSH levels were higher in patients undergoing postoperative debridement (p=0.03) or local flap procedures (p=0.04). Malnutrition, hypothyroidism, and substance abuse correlated with a higher incidence of postoperative wound complications in patients undergoing FF reconstruction for advanced osteoradionecrosis. Preoperative antibiotics use did not correlate with a reduction in postoperative wound complications.
