[Application of anterolateral thigh flap preforming tongue in patients with total glossectomy].

To investigate the efficacy of anterolateral thigh flap preforming tongue in patients with total glossectomy. A total of 27 patients with tongue cancer who underwent total glossectomy, neck lymph node dissection and anterolateral thigh flap transfer were collected from January 2019 to April 2021 in the Department of Oral and Maxillofacial Surgery at the Second Xiangya Hospital. All patients were males, the age ranged from 35-73 years. The patients were divided into experimental (14 cases) and control (13 cases) groups, based on whether the tongue was reconstructed. The clinical parameters of two groups were analyzed by independent sample test or Fisher exact probability method. The success rate of free flap was 100%, of the patients, 2 patients had cervical hematoma and 1 patient had wound infection postoperatively. There was no difference in speech (6.69±3.42 . 5.50±3.01, =0.96, =0.346) or swallowing (χ=0.46, =0.793) function between two groups at 1 month after surgery. However, the speech (24.94±7.43 . 18.44±6.30, =2.48, =0.020) and swallowing (χ=6.97, =0.008) functions in experimental group were significantly better than those in control group. No case was lost to follow-up. All patients were extubated after operation, with average time of 7.2 days in the experimental group and 7.7 days in the control group. The overall survival rate was 71.4% in the experimental group and 61.5% in the control group. The use of anterolateral thigh flap preforming tongue can improve the speech and swallowing functions in patients with total glossectomy and offer a novel method for tongue construction.
