    The study evaluated the reproducibility of the Frankfort horizontal plane (FHP) using CBCT-based 3D reconstruction in patients with facial deformities.

  • 2

    Twenty-seven patients underwent both CBCT scanning and lateral cephalometric radiography for comparison of FHP establishment methods.

  • 3

    CBCT 3D reconstruction demonstrated good reproducibility for FHP, while lateral cephalometric measurements showed larger reproducibility errors.

  • 4

    Intra-class correlation coefficients and Bland–Altman analysis were used to assess reproducibility and agreement between the two methods.

  • 5

    The findings suggest that CBCT-based methods may enhance the reliability of FHP construction for craniofacial diagnosis and treatment planning.
