Summary
This study details the first successful mandibular lengthening of 20mm using automatic continuous distraction osteogenesis in a 65-year-old male patient. The innovative device utilized a bone-implanted component and an external pump for precise bone regeneration.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomedical Engineering
- Regenerative Medicine
Background:
- Mandibular hypoplasia presents significant reconstructive challenges.
- Conventional surgical techniques for mandibular lengthening can be complex and invasive.
- Advancements in distraction osteogenesis offer potential for improved outcomes.
Observation:
- A 65-year-old male patient underwent surgical intervention.
- The right ramus of the mandible was targeted for lengthening.
- A novel automatic continuous distraction osteogenesis device was employed.
Findings:
- The procedure successfully lengthened the right mandibular ramus by 20mm.
- The device comprised an internal bone-implanted component and an external portable unit.
- A non-compressible drive cable facilitated the distraction process.
Implications:
- This case demonstrates the feasibility of automatic continuous distraction osteogenesis for mandibular lengthening.
- The described device offers a potentially more controlled and automated approach to bone regeneration.
- Further research may explore wider applications in treating craniofacial deformities.
