In this study, we aimed to develop a new method for detection of aspiration based on B-mode video ultrasonography and to evaluate its performance. To detect aspirated boluses by B-mode video ultrasonography in patients with dysphagia, we placed a linear array transducer above the thyroid cartilage and observed the area around the vocal folds. Forty-two ultrasonographic measurements were obtained from 17 patients with dysphagia who also underwent videofluoroscopy or videoendoscopy measurements at the same time. Aspirated boluses were observed in B-mode video ultrasonographic images as hyperechoic, long, narrow objects that passed through the vocal folds beneath the anterior wall of the trachea, with movement different from that of the surrounding structure. The sensitivity of aspiration detection was 0.64, and the specificity was 0.84. This newly developed detection method will enable patients with dysphagia to receive appropriate daily swallowing care.
在本研究中，我们旨在开发一种基于B型视频超声检查的误吸检测新方法，并评估其性能。为了通过B型视频超声检查检测吞咽困难患者的误吸团块，我们将线性阵列换能器置于甲状软骨上方，并观察声带周围区域。从17例吞咽困难患者中获得了42次超声测量结果，这些患者同时还接受了电视荧光吞咽造影或视频内镜检查。在B型视频超声图像中，误吸团块表现为高回声、长而窄的物体，穿过气管前壁下方的声带，其运动与周围结构不同。误吸检测的敏感性为0.64，特异性为0.84。这种新开发的检测方法将使吞咽困难患者能够接受适当的日常吞咽护理。
