Computer-assisted navigation using the Surgical Segment Navigator (SSN) precisely guides temporomandibular joint (TMJ) positioning during Le Fort I osteotomy. This technology significantly reduces TMJ malposition compared to conventional methods.

Area of Science:

Oral and Maxillofacial Surgery
Computer-Assisted Surgery
Orthognathic Surgery

Background:

Le Fort I osteotomy can alter temporomandibular joint (TMJ) position.
Surgeons lack direct visual control of the TMJ during this procedure.

Purpose of the Study:

To intraoperatively record TMJ movements during Le Fort I repositioning osteotomy.
To evaluate the effectiveness of the Surgical Segment Navigator (SSN) in guiding TMJ position.

Main Methods:

Recorded unintended TMJ positions after conventional maxillary repositioning.
Utilized SSN to correct TMJ positions relative to the skull base.
Compared accuracy of conventional versus SSN-guided adjustments.

Main Results:

Median condyle malposition without navigation was 2.4 mm.
SSN-guided corrective positioning reduced malposition to 0.7 mm.

Conclusions:

The Surgical Segment Navigator (SSN) enables accurate intraoperative navigation of the temporomandibular joint (TMJ).
SSN improves precision in orthognathic surgery by controlling TMJ position.
