We evaluated the tongue to Palatal Augmentation Prosthesis (PAP) contact pressures and pharyngeal pressure during swallowing for post-operative head and neck cancer patients and patients with dysphagia. Wearing PAP brought higher tongue to PAP contact pressure in the areas of tongue resection. The simultaneous evaluation of Video Fluorography and pharyngeal pressure showed lower pressure at the tongue base in the patients with penetration and aspiration.
