The main aim of the present report is to describe our learning curve in microsurgery and how we solved the problems that frequently occur during the first phases of this learning curve. We analyzed the medical records of 69 patients that underwent head and neck reconstruction with free flaps in our department. The patients were divided into two groups. Group 1 included the patients reconstructed between January 2011 and June 2017, whilst Group 2 included those reconstructed between July 2017 and August 2018. A χ2 test was used to compare the differences between the two groups in terms of flap failure (failure and partial failure) and eventual clinical errors. The p value was set at 0.05. Flap failure and clinical errors were most frequently observed in Group 1 (p < 0.05). Greater awareness of the need for proper functioning of the anastomosis during surgery, along with more exhaustive postoperative monitoring might explain the lower number of failures and signs of vascular compromise observed in Group 2. A number of variables may influence flap survival. Postoperative care, head position, kinking, body temperature, blood pressure and the ability to recognize the sign of vascular compromise all play a fundamental role following surgery. However, microsurgery is not just a routine type of surgery, and a properly trained team with several types of professionals must be adequately prepared to obtain acceptable results.
