Speech-aid prostheses for neurogenic velopharyngeal incompetence.
BACKGROUND
When surgical treatment is not considered an option, prosthetic management of velopharyngeal insufficiency is carried out by means of a speech-aid prosthesis, whereas velopharyngeal incompetence is traditionally managed by a palatal lift prosthesis. Varying degrees of treatment success have been attributed to palatal lift prostheses.


OBJECTIVE
This study introduces the use of nasopharyngeal obturation instead of palatal elevation for the management of velopharyngeal incompetence.


METHODS
Seven patients afflicted by neurogenic velopharyngeal incompetence were treated with wire-extension speech-aid prostheses constructed to circumvent the dysfunctional soft palate. The shape of the nasopharyngeal section was functionally molded in speech and swallowing and controlled by video-nasopharyngoscopic examinations.


RESULTS
Effective nasopharyngeal obturation with notable improved speech was achieved in all patients. Even though all patients ultimately tolerated the prostheses well, 2 patients denied any improvement in speech with the finalized prostheses.


CONCLUSIONS
Wire-extension speech-aid prostheses used by the patients were an effective treatment approach for velopharyngeal incompetence. Nasopharyngoscopic control is mandatory for maximizing the effect of velopharyngeal closure around the nasopharyngeal section of the prosthesis in function, yet it allows free nasal breathing. Velopharyngeally incompetent patients should be carefully tailored for prosthetic treatment because of contingent noncompliance.
