Summary
A new Vancouver microstomia orthosis effectively corrected microstomia in burn patients. This oral prosthesis significantly improved active mouth opening range of motion within 9 weeks.
Area of Science:
- Oral and Maxillofacial Surgery
- Burn Rehabilitation
- Prosthodontics
Background:
- Microstomia, or limited mouth opening, is a common complication following severe burns.
- Existing microstomia orthoses have limitations in efficacy and patient compliance.
- Developing effective interventions is crucial for restoring function and quality of life.
Purpose of the Study:
- To compare existing microstomia orthoses and introduce a novel prosthesis.
- To evaluate the effectiveness of the Vancouver microstomia orthosis in treating microstomia.
- To assess the impact of the orthosis on active range of motion.
Main Methods:
- A comparative review of 18 existing microstomia orthoses.
- Design and fabrication of the Vancouver microstomia orthosis.
- Clinical evaluation of 10 adult patients with microstomia due to flame burns over 12 months.
Main Results:
- The Vancouver microstomia orthosis demonstrated significant improvement in microstomia.
- Patients achieved an average gain of 7 mm horizontally and 13 mm vertically in active range of motion.
- Treatment success was achieved in 9 weeks or less, with statistically significant results (p < .01).
Conclusions:
- The Vancouver microstomia orthosis is a highly effective treatment for microstomia secondary to burns.
- This novel prosthesis offers a significant improvement in oral function and active range of motion.
- The study highlights the potential of this orthosis in burn rehabilitation and reconstructive surgery.
