To evaluate the curative effect of CO₂ laser in the treatment of laryngeal carcinoma.

A retrospective analysis of 152 cases of early laryngeal carcinoma treated with laser surgery between 2011 and 2014 was conducted. Among all cases, 11, 102, 31, and 8 were Tis, T1a, T1b, and T2 cases, respectively.

After the CO₂ laser treatment, patients were discharged within 1-3 days. There were no complications, such as dyspnea and tracheotomy, during the perioperative period. The long-term pronunciation quality was satisfactory. The follow-up period was 4-8 years. The recurrence rate of glottic carcinoma was 8.2% (147 cases). Two patients had salvage surgery with CO₂ laser. Six patients had salvage partial laryngectomy and four cases total laryngectomy. The five-year overall survival rate was 96.6%. Five cases of supraglottic carcinoma were followed up for 5 years without recurrence.

CO₂ laser surgery is a minimally invasive, effective, and safe procedure for early laryngeal carcinoma. Satisfactory exposure, good surgical skills, and appropriate surgical indications are fundamental for the success of CO₂ laser treatment.
