Evaluation of post-laryngectomy dysphagia rehabilitation using High-Resolution impedance manometry: an exploratory study.

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,
