Article Synopsis
  • The study investigates the effectiveness of a new soft palatal augmentation prosthesis (PAP) in improving communication (dysarthria) and swallowing (dysphagia) issues in patients with neurological conditions or post-tongue cancer surgery.
  • Researchers will conduct a randomized controlled trial comparing rehabilitation with and without the soft PAP, measuring outcomes like speech intelligibility and swallowing efficiency.
  • The findings will contribute to the understanding of pap's role in rehabilitation and will be shared in a peer-reviewed journal and at conferences.
