Pharyngeal solid-state manometry catheter movement during swallowing in dysphagic and nondysphagic participants.
The movements of the soft palate and the larynx are crucial in pharyngeal manometry because of the potential risk of manometry sensor dislocation. ⋯ High resting pressure in the UES permitted the sphincter to grasp the manometry catheter and caused the sensor to follow the cranial movement during laryngeal elevation. Sensor movement is important during pharyngeal manometry, and sensor dislocation out of the sphincter can be misinterpreted as sphincter relaxation. Simultaneous videoradiography provides control of sensor positioning and allows for correction.
