Abstract

Complete obturation of the nasopharynx can cause functional problems with breathing and swallowing due to obstruction of the nasal airway. A technique is described whereby a one way valve was incorporated in an obturator to allow normal nasal inspiration whilst maintaining an oropharyngeal seal during swallowing and speech.
