Laryngeal function preservation in surgical treatment of posterior hypopharyngeal wall carcinoma

Objective: To explore the feasibility of surgical treatment of posterior hypopharyngeal wall carcinoma and laryngeal function preservation.Methods: 61 patients with posterior hypopharyngeal wall carcinoma underwent operations.Results: 38 patients were surgically treated with the laryngeal functions preserved and 23 patients without laryngeal functions preserved.The 3-and 5-year survival rates of the laryngeal functions preserved group were 45%(17/38)and 16%(6/38) respectively.The 3-and 5-year survival rates of group without laryngeal functions preserved were 50%(10/20) and 15%(3/20) respectively.There was no significant difference between the two groups.Conclusion: Preservation of larynx normal part is feasible for a majority of posterior hypopharyngeal wall carcinoma patients underwent eradication of the tumor.
