a) Palatal lift prosthesis
b) Obturator prosthesis
c) Pharyngeal speech prosthesis
d) Pharyngeal bulb prosthesis
The correct answer is A. Palatal lift prosthesis.
Palatal lift prosthesis is useful for patients with velopharyngeal incompetence who exhibit compromised motor control of the soft palate & related musculature. The objective of palatal lift prosthesis is to displace the soft palate to the level of normal palatal elevation, enabling closure by pharyngeal action.
