To explore the effect of vocal cord reconstruction with sternohyoid muscle flap pedicled with vertical anterior laryngectomy. The clinical data of 43 cases of laryngeal carcinoma were analyzed retrospectively. According to whether the vocal cords were reconstructed, they were divided into vocal cord reconstruction group and non reconstruction group. Among them, 20 patients in the reconstruction group were reconstructed with pedicled sternohyoid muscle flap and 23 patients in non-reconstruction group. In the non reconstruction group, the external membrane of thyroid cartilage was used to repair the wounds. Postoperative respiratory function, swallowing function, pronunciation function, postoperative prognosis, complications, and recurrence rate were compared between the two groups. Reconstruction of glottis after vocal cord reconstruction was evaluated by electronic laryngoscope and CT scan. ①Patients in both groups survived during the follow-up period. One patient in the non-reconstructed group had recurrence, and the reconstituted group had no relapse, 3 cases with complications occurred in the reconstruction group, including 2 cases with granulation tissue in the glottic area, 1 case with laryngeal fistula, and 2 cases with aspiration pneumonia were found in the non-reconstruction group. ②1 year postoperative tracheal cannula removal rate, gastric tube removal and pronunciation quality: the tracheal cannula removal rate was 100% in the two groups after surgery; the gastric tube removal time in the reconstruction group was(13.2±2.8) days, and (16.6±5.3) days in the non-reconstruction group (0.05), and those with good pronunciation were statistically different (0.05); however, the transverse and anteroposterior diameter in the non-reconstructed group was significantly different with that of the normal people (>0.05), the transverse diameter of the reconstructed group and the non-reconstructed group were compared with no significant difference (>0.05), but there was significant difference in the anteroposterior diameter between the two groups (<0.05). The area in both groups were different with the normal people (<0.05); ④Glottic area morphology: the two groups of patients showed different degrees of swelling in the arytenoid cartilage area, the shape of the glottic region in the reconstructed group was approximately triangular, and the glottic morphology in the non-reconstructed group was approximately circular. After vocal cord reconstruction, there were increased rate of tracheal cannula extubation, well covered wallowing and phonation function, and the quality of life of patients was improved.
