Abstract
AbstractBackgroundTraditionally, patients undergoing free flap reconstruction for oral cavity defects have been given nothing by mouth for 6–14 days post‐operatively due to concern for orocutaneous fistula development.MethodsMultiple databases were screened for studies assessing the rate of orocutaneous fistula formation in early (≤5 days) versus late (>5 days) feeding groups following oral cavity free flap reconstruction. Fixed‐ and random‐effects meta‐analyses were used.ResultsOne randomized controlled trial, one prospective cohort, and three retrospective cohort studies were included. The early feeding group displayed no significant increase in orocutaneous fistula formation (RD = −0.02, p = 0.06) or free flap failure (RD = −0.01, p = 0.39), with a significantly shorter hospital length of stay (mean difference [days] = −2.43, p < 0.01).ConclusionsWhile further prospective trials are necessary, initiation of oral intake before post‐operative day 5 may be appropriate in properly selected patients following oral reconstruction.
