喉切除术后语音重建的新手术技术提供了一种简单有效的沟通方法，但需要在讲话时手动闭合气管造口。我们报告了一种独特的气管造口阀门的开发，该阀门无需覆盖造口。这个气流敏感阀在说话时关闭，在正常呼吸时保持打开。一项在10个月内对50名患者进行的临床试验的结果令人鼓舞。我们的经验表明，过多的声道气流阻力是有效使用瓣膜的主要限制因素。本文讨论了通过减少气流阻力来改善发声和气管造口阀使用的方法。
Newer surgical techniques for postlaryngectomy voice rehabilitation provide a simple, effective method of communication but require manual occlusion of the tracheostoma during speech. We report the development of a unique tracheostoma valve that avoids the necessity for covering the stoma. This airflow-sensitive valve closes during speech and remains open with normal respiration. Results of a clinical trial with 50 patients over a ten-month period are encouraging. Our experience suggests that excessive vocal tract resistance to airflow is the principal limitation to effective valve use. Approaches to decreasing airflow resistance through the vocal tract to improve both voice production and tracheostoma valve use are discussed.
