The practice of Pearson's (1981) technique of near total laryngectomy with speech shunt is evaluated acoustically in 11 subjects using matched esophageal speakers. Not only do these patients vocalize earlier with effortless cease, analysis of their speech both subjectively & by acoustic analysis of the parameters seems definitely to be of superior quality. The functional utility of this technique is addressed in this study justifying its more frequent practice in unilateral lesions of larynx and hypopharynx which defy satisfactory control by conventional conservation laryngeal surgery or radiation therapy. The Oncological outcome will be taken up as a part of a future report when follow up of adequate duration occurs in sufficient number of cases.
采用匹配的食管发声者，对11名受试者的Pearson（1981年）近乎全喉切除术加语音分流技术的实践进行了声学评估。这些患者不仅发声更早且能轻松终止发声，对他们语音的主观分析以及对参数的声学分析似乎都显示语音质量明显更优。本研究探讨了该技术的功能效用，证明其在单侧喉和下咽病变中更频繁应用的合理性，这些病变无法通过传统的保留喉手术或放射治疗得到满意控制。当足够数量的病例有足够长的随访时间时，肿瘤学结果将作为未来报告的一部分进行阐述。
