Impression and custom preparation; palatal augmentation prosthesis
CPT4 code
Name of the Procedure:
Impression and Custom Preparation; Palatal Augmentation Prosthesis
Common name(s): Palatal lift prosthesis, Speech bulb prosthesis.
Medical term: Palatal augmentation prosthesis.
Summary
The procedure involves taking an impression of the palate and preparing a custom prosthesis that fits the roof of the mouth. This prosthesis helps improve speech and swallowing by compensating for structural or functional deficiencies in the palate.
Purpose
Medical Condition:
This procedure addresses velopharyngeal insufficiency (VPI), a condition where the soft palate does not close properly against the back of the throat during speech or swallowing, resulting in nasal air escape and speech problems.
Goals:
- Improve speech clarity.
- Prevent nasal regurgitation of food and liquids.
- Enhance overall swallowing efficiency.
Indications
Symptoms/Conditions:
- Hypernasality in speech.
- Nasal regurgitation.
- Difficulty swallowing (dysphagia).
Patient Criteria:
- Diagnosed with VPI.
- Inadequate response to speech therapy.
- Structural abnormalities (e.g., cleft palate, post-surgical changes).
Preparation
Instructions for Patients:
- No specific dietary restrictions or fasting required.
- Maintain good oral hygiene before the appointment.
Diagnostic Tests:
- Speech evaluation.
- Nasopharyngoscopy to assess the structure and function of the soft palate.
Procedure Description
- The dentist or prosthodontist will first take an impression of your palate using a dental impression material to capture an accurate mold of the area.
- The impression is sent to a dental lab where a custom prosthesis is crafted.
- During the fitting appointment, the prosthesis will be adjusted for comfort and function.
- The prosthesis may be attached to existing dentures or designed as a standalone device.
Tools and Equipment:
- Dental impression trays.
- Impression material (e.g., alginate or silicone).
- Prosthetic design tools.
Anesthesia:
- Generally, no anesthesia is required.
Duration
- Impression taking: Approximately 30 minutes.
- Fitting and adjustment: 1-2 hours.
Setting
- Outpatient dental clinic or prosthodontist's office.
Personnel
- Prosthodontist or dentist.
- Dental assistant.
Risks and Complications
Common Risks:
- Minor discomfort during impression taking.
- Initial speech adaptation difficulties.
Rare Risks:
- Sore spots in the mouth from prosthesis pressure.
- Allergic reactions to impression materials.
Management:
- Follow-up appointments for prosthesis adjustments.
- Use of soothing oral gels if sore spots occur.
Benefits
Expected Benefits:
- Enhanced speech clarity within a few weeks.
- Improved swallowing and reduced nasal regurgitation immediately after fitting.
Recovery
Post-procedure Care:
- Regular cleaning of the prosthesis.
- Follow-up visits for adjustments and evaluation.
Recovery Time:
- Immediate ability to wear the prosthesis.
- Adaptation period for speech improvements may take several weeks.
Alternatives
- Speech therapy alone, although less effective for structural VPI.
- Surgical correction (e.g., pharyngeal flap surgery), which is more invasive and carries surgical risks.
Pros and Cons:
- Prosthesis: Non-invasive, reversible, adjustable.
- Surgery: Permanent solution, requires recovery time, potential surgical risks.
Patient Experience
During Procedure:
- Slight discomfort during impression material setting.
- Feeling of pressure during fitting.
After Procedure:
- Period of adjustment to speaking with the prosthesis.
- Minimal post-procedure discomfort.
- Regular oral hygiene and prosthesis maintenance to ensure comfort and functionality. Pain management is generally not required due to the non-invasive nature of the procedure.
