Area of Science:

Oral and Maxillofacial Surgery
Orthodontics
Medical Imaging

Background:

Three-dimensional (3D) assessment of orthognathic surgery is challenging due to time constraints and manual landmark identification.
Current methods often lack precision for segmental osteotomies, limiting accurate outcome evaluation.

Purpose of the Study:

To propose and validate an automated approach for the 3D assessment of segmental bimaxillary surgery.
To evaluate the accuracy and postoperative outcomes of this novel virtual surgical analysis (VSA) method.

Main Methods:

A semi-automatic virtual surgical analysis (VSA) was developed and validated using pre- and postoperative cone-beam computerized tomography (CBCT) scans.
Accuracy was quantified by 3D translational and rotational differences between planned and actual bone segment movements.
Reliability was assessed using intra-class correlation coefficients (ICC) and observer measurements against a clinical threshold.

Main Results:

The study included 10 subjects undergoing segmental bimaxillary surgery (3-piece Le Fort I, bilateral sagittal split osteotomy, genioplasty).
Excellent intra- and inter-observer reliability was achieved, with ICC values ranging from 0.96 to 1.00.
Mean absolute differences in measurements were significantly lower than the hypothesized clinical thresholds (p < .001).

Conclusions:

The validated virtual surgical analysis (VSA) offers excellent reliability for quantitative assessment.
This automated approach accurately evaluates the postoperative outcomes and precision of segmental bimaxillary surgery.
