ObjectiveTo explore the feasibility and superiority of improved supracricoid partial laryngectomy for the treatment of laryngeal carcinoma.Methods25 patients suffering from laryngeal carcinoma of early and medium stage received improved supracricoid partial laryngectomy. During the operation, phonation function was reconstructed with reversal of residual arytenoid mucosa, combined with simultaneous cricoepiglottopexy via direct suture of epiglottis with cricoid cartilage or cricothyroid membrane. All patients were followed up postoperatively to evaluate the therapeutic effect.ResultsDuring the followup period ranged from 1 to 3 years, no death occurred. The decannulation rate was 100% with an average decannulation time of 45 days. The incidence of aspiration was 52%. All patients had clear pronunciation as well as normal verbal communication. One patient underwent postoperative functional neck dissection due to cervical lymph node metastasis, and another one received total laryngetomy due to postoperative local recurrence.ConclusionWith advantages of simple maneuverability and easy grasping, the improved supracricoid partial laryngectomy can effectively improve the postoperative decannulation rate, reduce the incidence of laryngeal stenosis, improve the quality of pronunciation as well as the quality of life in patients with laryngeal carcinoma.
