Prosthetics for Structural Deficits

Prosthetic speech management is a viable treatment option for selected patients with structural or neurogenic speech disorders. Structurally based disorders typically require a prosthesis that will obturate the space of an oropharyngeal defect. Disorders of neurogenic origin, resulting in dysarthria that affects velopharyngeal (VP) function, may be managed by lifting the soft palate into position. The two most common prosthetic devices include the palatal obturator (also known as a speech bulb) and the palatal lift, both of which aim to improve VP closure for speech.
