Quality of voice is an important factor in the consideration of treatment for advanced laryngeal cancer. This prospective study compared the speaking proficiency of patients who used the Blom-Singer valve after total laryngectomy and after total laryngopharyngectomy with jejunal graft reconstruction with that of a group of normal subjects. The total laryngectomy group demonstrated excellent communication ability both face-to-face and on the telephone. They exhibited superior scores for objective intelligibility, subjective intelligibility, acceptability, and intonation when compared with the total laryngopharyngectomy group. Both surgical groups produced similar amplitude and frequency parameters during normal conversation but had limited reserve when these functions were stressed. Despite these quantitative variations, patient acceptance was very high in both surgical groups. These results serve as a foundation for the evaluation and improvement of rehabilitation techniques.
嗓音质量是晚期喉癌治疗方案考量中的一个重要因素。这项前瞻性研究比较了全喉切除术后以及全喉咽切除术后行空肠移植重建术的患者使用Blom-Singer瓣膜后的言语能力与一组正常受试者的言语能力。全喉切除组在面对面交流和电话交流中均表现出出色的沟通能力。与全喉咽切除组相比，他们在客观可懂度、主观可懂度、可接受度和语调方面得分更高。两个手术组在正常对话时产生的振幅和频率参数相似，但在这些功能受到压力时储备有限。尽管存在这些定量差异，但两个手术组患者的接受度都很高。这些结果为评估和改进康复技术奠定了基础。
