Summary
This study introduces a new trans-sinusoidal maxillary distractor (TS-MD) for treating severe maxillary hypoplasia. The TS-MD device allows predictable maxillary advancement and correction of open-bite deformities with good patient tolerance.
Area of Science:
- Maxillofacial surgery
- Orthodontics
- Biomedical engineering
Context:
- Severe maxillary and midfacial hypoplasia presents significant challenges in treatment.
- Existing distraction osteogenesis devices may have limitations in placement and patient comfort.
Purpose:
- To evaluate a novel trans-sinusoidal maxillary distractor (TS-MD) with an integrated activating system.
- To assess the efficacy and tolerance of the TS-MD in correcting maxillary hypoplasia and associated deformities.
Summary:
- Fourteen patients with severe maxillary hypoplasia underwent treatment using the intra-oral TS-MD device.
- Predictable maxillary movements (7-22 mm) and complete bone healing were achieved.
- The device facilitated correction of anterior open-bite and minimized social interference.
Impact:
- The TS-MD offers good patient tolerance due to intra-sinus placement, simplifying the surgical approach.
- This device may reduce the need for bone grafting in major advancement cases.
- Predictable vector control and potential for catch-up distraction enhance clinical utility.
