Clinical effect comparison of chimeric anterolateral thigh flap and tandem skin flap on repair of oral and maxillofacial tumors after radical surgery

Objective To analyze and compare the clinical effect of anterolateral chimeric flaps and tandem skin flap on repair of oral and maxillofacial tumors after radical surgery. Methods Total 102 patients with oral and maxillofacial tumors after radical surgery repair in our hospital between December, 2014 and December, 2016 were selected as study objects, and were divided into group A (anterolateral chimeric flaps), group B (tandem skin flap) according to the surgery methods, with 51 cases in each group. The surgical conditions (operation time, flap production and microsurgical anastomosis time, gastric tube removal time, oral feeding time), postoperative recovery (satisfaction, shape recovery, food intake, work condition, oral closure, mouth opening, chewing function, swallowing function, bite function, language function), and serum IL-2, sIL-2R and SA levels of the two groups were compared. Results The operation time, gastric tube removal time and oral feeding time of group A were significantly lower than those of group B (P<0.05) and the production time and microscopic anastomosis time of group A were significantly higher than those of group B (P<0.05). Three months after the surgery, the satisfaction, appearance repair, work condition, oral closure, masticatory function, swallowing function and language function of group A were significantly higher than those of group B (P<0.05). One month after the operation, the serum IL-2 levels of the two groups were significantly increased, and the IL-2 level of group A was significantly higher than that of group B (P<0.05). One month after the operation, the serum sIL-2R and SA levels of the two groups were significantly increased, and the level in group A was significantly lower than that in group B (P<0.05). The incidence of vascular crisis in group A was 3.92%, which was significantly lower than that in group B (17.65%, P<0.05). Conclusion The chimeric anterolateral skin flap can repair the defect of the maxillofacial tumor after radical operation, which can significantly shorten the operation time and improve the postoperative functional recovery. The incidence of postoperative complications is low.
