Due to the microvascular effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), head and neck reconstructive surgeries utilizing free tissue transfers may be profoundly affected by SARS-CoV-2 infection in the immediate postoperative period. Our objective is to describe two adult patients who developed SARS-CoV-2 after undergoing relatively uncomplicated segmental mandibulectomies. In both cases, the patients were initially negative for SARS-CoV-2, underwent relatively uncomplicated segmental mandibulectomies with fibula free flap reconstructions, and were later discharged in stable conditions. Both patients subsequently experienced significant infectious sequelae at the donor and recipient sites with near-total split-thickness skin graft loss in the donor sites in the setting of postoperative SARS-CoV-2 infection. The first patient developed sepsis and gangrenous changes to his fibula donor site requiring four operative debridements and partial amputation with subsequent osteomyelitis of the remaining fibula. The second patient experienced dehiscence of the oral fibula free flap as well as a 22 cm phlegmon at the fibula donor site that required surgical debridement. In consideration of these cases, SARS-CoV-2 infection during the immediate postoperative period of head and neck reconstruction procedures may elevate the risk of major wound complications. Special consideration must be taken when performing free tissue transfers during the COVID-19 pandemic.
