Preserving laryngeal function in surgery of hypopharyngeal carcinoma

Objective:To investigate the feasibility and the results of laryngeal function preservation in surgical treatment of hypopharyngeal carcinoma. Method: 23 cases with hypopharyngeal carcinoma were treated with function-sparing laryngectomy and received postoperative radiotheraphy and the defect of laryngeal pharynx was constructed by various material such as muscular fasciae, et al. Results: Vocalization was recovered in all the patients and complete restoration of laryngeal function was achieved in 16 cases. The deglutition restoration rate and complication incidence were 95.7% and 47.8% respectively. The 3-year survival rate was 69.6% and 5-year survival rate was 47.8%. Conclusion: It is feasible for major patients with hypopharyngeal carcinoma to preserve the normal parts of the larynx and restitute the function of the larynx. The effect of operation is satisfactory.
