【摘要】 目的了解影响Blom-Singer发音管发声障碍的各种相关因素。方法回顾性分析1996年4月~2006年10月108例喉全切除术后行Blom-Singer发音管重建喉发声功能患者的临床资料,其中施行Ⅰ期Blom-Singer发声重建术96例,Ⅱ期Blom-Singer发声重建术12例,并对其发声效果进行追踪观察。结果96例行Ⅰ期发音管重建术中,22例发声质量差(22/96,23%);12例行Ⅱ期发音管重建术中,8例发声质量差(8/12,67%)。两种术式的总失败率为(30/108,28%)。结论Ⅰ期Blom-Singer发声重建术较Ⅱ期Blom-Singer发声重建术成功率高。术后发声质量的效果与环咽肌的处理、气管食管壁的完整性、气管造瘘口的大小、咽瘘、食管下咽腔狭窄及肺功能等因素密切相关。更多还原

【Abstract】 Objective To explore relative factors affecting dysphonia of the Blom-Singer pronunciation tube.Methods The clinical data of 108 patients who had undergone Blom-Singer voice producing reconstruction following total laryngectomy were retrospectively analyzed.96 cases received stage Ⅰ Blom-Singer voice producing reconstruction,and the other 12 cases underwent stage Ⅱ Blom-Singer voice producing reconstruction.Results 22 of 96 cases who had undergone stage Ⅰ Blom-Singer voice producing reconstruction had less effective phonation(22/96,23%),and 8 of 12 cases who had undergone stage Ⅱ Blom-Singer voice producing reconstruction did not get the expected voice(8/12,67%),and the total failure rate of the two operative methods was 28%.Conclusion The successful rate of stage Ⅰ Blom-Singer voice producing reconstruction was higher than that of the stage Ⅱ Blom-Singer voice producing reconstruction.Effect of voicing quality after the operations was closely related to following factors,such as treatments to the cricopharyngeal muscle,integrity of the tracheo-esophagus wall,size of the trachea stoma,pharyngeal fistula,stenosis of the esophagus hypo-pharyngeal cavity and pulmonary function of patients.更多还原
