Orthognathic Surgery Facial Analysis Metrics for 128 Patients

128 patients underwent bimaxillary surgery between 2014 and 2019. This dataset provides pre- and postoperative measurements from Brons-Mulié profile analysis, Nakamura's asymmetry index, and a simple enface analysis for objective surgical assessment. It was authored by Sebastian Böttger and published in 2026.

Use Cases

• Analyze variance changes in mandibulofacial height and lower lip inclination from Brons-Mulié analysis to quantify surgical impact.
• Assess asymmetry correction using Nakamura's Asymmetry Index parameters like nostril position, lip angles, and jaw angles.
• Evaluate midline position and chin position shifts measured in the enface analysis for postoperative quality assurance.
• Apply F-test and Fligner-Killeen-Test to compare pre- and postoperative variances across all measured parameters.

Strengths

• Data from 128 patients provides a substantive clinical sample.
• Includes three established analysis methods (Brons-Mulié, Nakamura, enface) for multi-dimensional assessment.
• Covers a 5-year time range from 2014 to 2019 for longitudinal study.

Limitations

• Dataset is small at 9.7 MB, likely containing summary results rather than raw patient-level data.
• Data is presented in a PDF format, requiring extraction for computational analysis.
• Limited to patients who underwent bimaxillary surgery, not representing all orthognathic procedures.
