Objective:To evaluate the clinical effect of laryngofissure without tracheotomy.Method:One hundred and sixteen cases of laryngofissure without tracheotomy in our department were analyzed retrospectively.Result:Of 116 cases, 101 cases had the laryngeal carcinoma; 9 cases had laryngeal stenosis; 6 cases had benign tumor of larynx. All the incisions were healed by first intention; and postoperative duration of hospital stay were 7 to 20 days. Three cases recurred in 101 cases of laryngeal carcinoma (2.97%), and underwent reoperation,the 5 year survival rate was 100%. One case recurred in 9 cases of laryngeal stenosis, and underwent reoperarion of laryngoplasty with T-tube implanted. No recurrence in 6 cases of benign tumor of larynx.Conclusion:Laryngofissure without tracheotomy have the advantage of less trauma , fast rehabilitation and no destroying the normal respiratory functions. It is completely feasible so long as surgeons grasp the adaption of operation strictly and select suitable cases.
