Abstract

Velopharyngeal dysfunction is frequently associated with motor speech disorder. Palatal lift prostheses are an accepted intervention for velopharyngeal dysfunction that is not responsive to behavioral interventions (Yorkston et al., 2001). However, there are individuals for whom the palatal lift is not an option due to motor, sensory, cognitive, or dental factors. To address this clinical need, we have developed a nasal obturator with a one-way valve that opens to allow inhalation through the nose and closes during exhalation or nasal emission during speech. The present report describes the device and its implementation on two individuals with dysarthria and severe hypernasality.
