VELOPHARYNGEAL PROBLEMS

VELOPHARYNGEAL INSUFFICIENCY:

Patients with inadequate length of hard or soft palate to affect veloph. closure BUT with normal movement

SPEECH AID PROSTHESIS

VELOPHARYNGEAL INCOMPETENCE:

Patients with normal veloph. Structures BUT unable to affect veloph. closure e.g. neurological disease.

PALATAL LIFT PROSTHESIS

1. Speech aid prosthesis Pediatric Is a temporary or interim prosthesis used to

close in the hard and/or soft palate, so it

separate the nasal and oral cavity to

facilitate breathing.

It may need several adjustment or even

replacement to permit palatal growth.

It is not fabricated before eruption of the

deciduous teeth since clasping is essential

It is used with VELOPHARYNGEAL INSUFFICIENCY: Patients with inadequate length of hard or soft palate to affect veloph. closure BUT with

normal movement

SPEECH AID PROSTHESIS

VELOPHARYNGEAL INCOMPETENCE

Patients with normal veloph. Structures

BUT unable to affect veloph. closure e.g.

neurological disease.

PALATAL LIFT PROSTHESIS Prosthesis used to elevate the soft plate and aid to restore the soft palate functions that lost due to acquired , congenital or developmental defect. It may be defective treatment if the surgical repair un wanted

Definitive Treatment

1. Mobile Prosthesis: Dela Berre 1820

It is a prosthesis with soft rubber velar as

in more simple hinged type obturator to

biocompatible with the movement of the of

soft palate.

2. Meatus

Obturator:

Used to reduce the

resonance of the

nasopharnx.

3. Fixed Pharyngeal Obturator (speech Type)

Is a space filling the cleft space and designed to be

held in the lower region of the nasopharnx and is

formed to compensate for tissue insufficiency

Patients with inadequate length of hard or soft palate to affect veloph. closure

BUT with normal movement
