International audience; Free-flap mandibular reconstruction is a highly specialized procedure associated with severe complications necessitating re-interventions and re-hospitalizations. This surgery is expensive in terms of health workers' time, equipment, medical devices and drugs. Our main objective was to assess the direct hospital cost generated by osseocutaneous free-flap surgery in a multicentric prospective micro-costing study. Direct medical costs evaluated from a hospital perspective were assessed using a micro-costing method from the first consultation with the surgeon until the patient returns home, thus confirming the success or failure of the free-flap procedure. The mean total cost for free-flap intervention was 34,009€ (5151-119,604€), the most expensive item being the duration of hospital bed occupation, representing 30-90% of the total cost. In the event of complications, the mean cost increased by 77.3%, due primarily to hospitalization in ICU and the conventional unit. This surgery is effective and provides good results but remains highly complex and costly.
