Area of Science:

Orthognathic surgery
Craniofacial reconstruction
Distraction osteogenesis

Context:

Conventional Surgical Assisted Rapid Maxillary Expansion (SARME) yields limited posterior skeletal widening.
Integrating Le Fort I osteotomy with palatal distraction was previously challenging due to hardware limitations.
A new device enables combined Le Fort I procedures with bipartite palatal distraction.

Purpose:

To introduce a novel bipartite palatal distractor system.
To describe the technical features and clinical applications of the new device.
To evaluate its potential in correcting complex maxillofacial deformities.

Summary:

A new palatal distractor features independent jacks for adjustable anterior/posterior distraction, available in bone-borne and tooth-borne designs.

The distractor allows for sagittal adjustment, enabling angular or parallel distraction modes adaptable during post-operative care.

It integrates with sliding osteosynthesis for combined Le Fort I osteotomy, addressing vertical, horizontal, and sagittal deficiencies.

Impact:

Facilitates simultaneous correction of multiple maxillofacial skeletal discrepancies.
Offers enhanced flexibility in managing complex cases requiring both advancement/impaction and transverse expansion.
Represents a significant advancement in surgical assisted maxillofacial reconstruction.
