Accelerometer transduced sounds of swallowing in total laryngectomees did not show acoustical differences for liquid vs paste swallows, as are found in normals. Compared with normal swallows, tongue propulsion of the bolus in laryngectomee swallows occurred closer in time to a distinctive spectral change associated with bolus flow into the esophagus. Interpretation stressed the lack of mechanical traction from laryngeal elevation contributing to pharyngoesophageal sphincter opening, and the increased role of tongue propulsion in laryngectomee swallows.
与正常人不同，全喉切除患者吞咽时加速度计转换的声音在液体吞咽和糊状吞咽之间未显示出声学差异。与正常吞咽相比，全喉切除患者吞咽时食团的舌推进在时间上更接近与食团流入食管相关的独特频谱变化。解释强调，喉提升缺乏机械牵引力导致咽食管括约肌开放，以及在全喉切除患者吞咽中舌推进的作用增加。
