Abstract

To investigate the therapeutic effect of transoral laser surgery in patients with early-stage glottic laryngeal cancer. 72 patients were randomly divided into an observation group (n=36) and a control group (n=36), who were diagnosed with early stage portal laryngeal carcinoma by pathological biopsy in our hospital from May 2017 to November 2019. The control group underwent conventional laryngectomy, while the observation group underwent carbon dioxide laser treatment under microscopic supported laryngoscopy. The patients’ treatment status and complications during the 6 mo postoperative follow-up period were also recorded. The results showed that 30 patients in the observation group and 6 patients in the control group had vocal cord neovascularization 6 mo after surgery and 20 patients in the control group had vocal cord neovascularization and 16 patients in the control group had vocal cord neovascularization. There were no statistically significant differences in the preoperative levels of vascular endothelial growth factor, Nitric oxide and tumor necrosis factor-alpha between the two groups (p>0.05), while the postoperative levels of vascular endothelial growth factor, Nitric oxide and tumor necrosis factor-alpha were statistically significant (p<0.05). The effective rate of treatment in the observation group was significantly higher than that in the control group, and the complication rate was lower than that in the control group (p<0.05). The application of micro-supported laryngoscopic carbon dioxide laser for the treatment of early glottic laryngeal carcinoma can improve the clinical treatment effect and reduce postoperative complications, which is worthy of application.
