<正> Objective: To evaluate subtotal laryngectomy with preservation of monoarytenoid cartilage to reconstruct laryngeal function in the treatment of advanced laryngeal cancer. Methods: We retrospectively reviewed 48 patients with advanced laryngeal cancer （T3 or T4 on the primary site） treated by subtotal laryngectomy with preservation of monoarytenoid cartilage to reconstruct laryngeal function. Eighteen of them underwent neck dissection. Ipsilateral recurrent laryngeal nerve was preserved during this surgery. The cricoid cartilage was anastomosed to hypopharynx accordingly. Results: The overall 3- and 5-year survival rates were 81. 25% （ 39/45） and 66. 67 %（32/48 ）

respectively. All patients had good phonation and swallowing function after surgery. Decannulation rate was 93. 75%. Conclusion: Subtotal laryngectomy with preservation of monoarytenoid cartilage is satisfactory for treatment of elected advanced laryngeal cancers. The effect of this surgery is more satisfactory than that of the near-total laryn
