The selection of appropriate recipient vessels is important for the success of head and neck reconstruction. Vessels located outside of previously-dissected neck regions tend to be more frequently selected due to relative ease of preparation. However, some advantages are offered regarding dead space filling and formation by using vascular anastomoses within regions previously dissected, or reusing former free flap pedicle due to their proximity to the defect. We analyzed microsurgical anastomoses in patients requiring oral reconstruction who had previously undergone neck dissection. Contralateral vascular anastomoses were preoperatively planned in 10 cases of which 9 could be successfully performed (achievement rate, 90%). Ipsilateral side anastomoses were planned in 28 cases, with 26 anastomosed as planned (achievement rate, 92.9%). There was no statistically significant difference between the two groups. Vascular anastomosis within the scar region can be performed safely, based on preoperative planning and intraoperative judgment.
