Abstract

Aim: This exploratory study analyzes High-Resolution Impedance Manometry (HRIM) data obtained during a phase II rehabilitation trial in laryngectomees at baseline (T0), after six-weeks of resistance-based training (T1), and after eight weeks of rest (T2), exploring its potential value in alaryngeal dysphagia research and clinical practice.

Methods: Pharyngeal HRIM was combined with videofluoroscopy to evaluate swallowing biomechanics in 17 laryngectomy patients. Parameters included Pharyngeal (Velo-, Meso-, and Hypopharyngeal) Contractile Integrals, Intra-Bolus Pressure, UES Relaxation Time, Maximum Admittance, and Integrated Relaxation Pressure.

Results: No significant differences were found in the Pharyngeal Contractile Integrals, Intra-Bolus Pressure, Relaxation Time, Maximum Admittance, or Integrated Relaxation Pressure. However, pharyngeal pressures and Maximum Admittance slightly decreased from T0 to T1, and increased at T2 for all consistencies (thin, extremely thick, solid).

Conclusion: Alaryngeal resistance-based swallowing exercises lead to small, non-significant differences in pharyngeal pressures. HRIM provides valuable insights, but its application for this population remains uncertain.

高分辨率阻抗测压法评价喉切除术后吞咽困难康复:一项探索性研究。
目的:本探索性研究分析了喉切除术患者在基线(T0)、6周阻力训练(T1)和8周休息(T2)后进行的II期康复试验中获得的高分辨率阻抗测压(hrm)数据,探讨其在咽吞咽困难研究和临床实践中的潜在价值。方法:对17例喉切除术患者的咽部hrm及x线影像进行吞咽生物力学评价。参数包括咽部(外咽、中咽和下咽)收缩积分、丸内压力、UES松弛时间、最大导纳和综合松弛压力。结果:在咽部收缩积分、丸内压力、松弛时间、最大导纳或综合松弛压力方面无显著差异。然而,咽部压力和最大导纳从T0到T1略有下降,在T2时,所有稠度(薄、极厚、固体)的咽部压力和最大导纳均有所增加。结论:基于咽阻力的吞咽练习导致咽压的小而不显著的差异。hrm提供了有价值的见解,但其在这一人群中的应用仍不确定。
