Summary

This summary is machine-generated.

The rigid external distraction (RED) device can reposition the maxilla, but it caused a counterclockwise rotation of the palatal plane in cleft lip and palate patients. Further vector control methods may be needed for desired clockwise rotation.

Area of Science:

Maxillofacial reconstruction

Background:

The rigid external distraction (RED) device is known for its ability to achieve three-dimensional repositioning of the maxilla.
Understanding its precise effects on maxillary rotation, specifically pitch, is crucial for optimizing treatment outcomes.

Purpose of the Study:

To assess the capability of the RED device to intentionally alter the maxillary pitch.
To evaluate the rotational changes in the palatal plane following maxillary distraction.

Main Methods:

A retrospective cohort study analyzing 50 patients over 12 years.
Cephalometric analysis of standardized lateral cephalograms comparing pre-distraction and post-consolidation variables.
Statistical comparison using a two-tailed paired t-test.

Main Results:

Mean maxillary advancement of 8.4 mm via distraction osteogenesis (DO).
Significant changes in SNA (10.2°), SNB (0.9°), and ANB (9.3°).
A mean counterclockwise rotation of the palatal plane by -4.4° was observed, despite superior eyelet placement.

Conclusions:

The RED device induced a counterclockwise rotation of the palatal plane in this cleft lip and palate population.
Adjunctive methods for vector control should be considered to achieve intentional clockwise rotation with the RED device.
