    Abstract
  •   Objective  The postoperative tissue defect of tongue cancer seriously affects the quality of life of patients, which requires improvement of their survival rate and quality of life. CT angiography (CTA), colour Doppler ultrasound (CDU) and their combination were used to assist in designing anterolateral thigh perforator flap for tongue reconstruction so as to seek the best reconstruction of tongue defect with the least damage.  Methods  From July 2017 to September 2020, 40 patients with tongue cancer undergoing surgery for tongue defect were selected from the Department of Stomatology of the First Affiliated Hospital of Bengbu Medical College. The patients were randomly divided into three groups by random number table. Twenty patients in group A were evaluated by CTA combined with CDU before operation, 10 patients in group B were evaluated by CTA before operation and 10 patients in group C were evaluated by CDU before operation. Skin flap repair was performed at the same time during the operation. Fisher accurate probability method was used to analyse the coincidence rate of perforating fulcrum and perforating branch type in the three groups. Variance analysis was used to analyse the operation time and postoperative hospital stay, with P < 0.05 as the statistical significance.  Results  All the flaps of 37 patients survived. One case in group A was partially necrotic, but the muscle flap survived. One patient in group B and group C still died of venous crisis after rescue. A significant difference was observed between groups A and C in the coincidence rate of perforating branch types (P=0.001). The time of skin flap preparation in group A was significantly better than those in groups B and C (P=0.004), but no significant difference was noted among the three groups in the coincidence rate of perforating branch points (P=0.244) and postoperative hospitalization days (P=0.845). Regarding primary healing of donor and recipient incision after operation, satisfactory results were achieved in tongue shape and function recovery, and no obvious complications were found in donor and recipient areas.  Conclusion  CTA combined with CDU has a good guiding significance in repairing postoperative defects of tongue cancer with anterolateral thigh flap.
