A long term study on treating velopharyngeal insufficiency by teflon injection
The Cleft Palate Journal
|January 1, 1982
Summary
Injectable Teflon is a safe and effective treatment for velopharyngeal insufficiency (VPI), achieving a 74% success rate. The implant material proved stable over time, offering a reliable solution for speech and voice quality improvement.
Area of Science:
- Otolaryngology
- Speech-Language Pathology
- Plastic Surgery
Background:
- Velopharyngeal insufficiency (VPI) affects speech and voice quality.
- Previous treatments like pharyngeal flaps can fail.
- Injectable Teflon offers a minimally invasive alternative.
Purpose of the Study:
- To evaluate the safety and efficacy of injectable Teflon for VPI treatment.
- To assess the long-term stability of Teflon implants.
- To determine success rates in various VPI patient groups.
Main Methods:
- 35 patients with VPI received injectable Teflon treatment.
- Speech and voice quality were evaluated pre- and postoperatively.
- Cinefluorography assessed Teflon pad stability over time.
Main Results:
- An overall success rate of 74% was achieved.
- Success rates were 78% for VPI patients (excluding failed flaps) and 62% for failed flap cases.
- No significant change in Teflon pad thickness was observed over time.
Conclusions:
- Injectable Teflon is a safe and effective treatment for VPI with careful patient selection.
- Teflon implants demonstrate long-term stability.
- This procedure offers a viable option for improving speech and voice in VPI patients.
