Objective: To evaluate the supraglottic horizontal partial laryngectomy in the treatment of laryngeal cancers.
Methods: Some researches and modifications are performed on the standard supraglottic horzontal partial laryngectomy: the wounded area in the laryngeal cavity is covered with the lateral membrane of thyroid cartilage; the laryngeal cavity is closed as its anterior wall by folding and sewing up the sternohyoid muscles. From 1983 to 1993, 92 patients (80 men and 12 women) with quamous cell carcinoma of larynx were treated with supraglottic horizontal partial laryngectomy. The patients age ranged from 39 to 72 years; 72% aged from 50 to 59. There were 72 cases (78.3%) in the stages III and IV.
Results: The 3 and 5 year survival rates of the patients were 75% and 72% respectively. Most cases have acquired good speech and swallow function with 2-4 weeks; 84.8% (78 patients) were extubated.
Conclusion: The authors believed that partial laryngectomy was safe and beneficial to some patients with laryngeal cancers.
