Abstract: Objective To determine the role of translaryngofissure CO 2 laser partial laryngectomy in laryngeal carcinomas.Methods The clinical data of 26 patients with laryngeal carcinoma,whose conditions were not for self-retaining microlaryngoscopic surgery.We did translaryngofissure partial laryngectomy by using CO 2 laser. Results Compared translaryngofissure CO2 laser partial laryngectomy with traditional partial laryngectomy,the average operation time was shortened by 20 minutes,reduced the laryngeal mucosa edema postoperatively.All patients were followed up for five years.The recurrence rate was significantly lower,without implantation metastasis.Conclusion Translaryngofissure CO 2 laser partial laryngectomy in laryngeal carcinoma has many advantages,for example shorter operation time, shorter laryngeal mucosa edema postoperatively.
