    A new stereophotogrammetric system combined with interactive computer graphics simplifies 3D facial analysis after surgery. This innovation aims to make facial contour mapping more accessible and efficient for surgical planning.

    Area of Science:

    • Medical imaging
    • Computer graphics
    • Plastic surgery

    Background:

    • Stereophotogrammetry is valuable for tracking facial changes post-surgery.
    • High personnel training requirements limit its widespread adoption.
    • Existing methods lack efficiency in analyzing complex 3D facial data.

    Purpose of the Study:

    • To develop an accessible stereophotogrammetric system for facial analysis.
    • To integrate interactive computer graphics for 3D data manipulation.
    • To overcome limitations of current facial mapping techniques.

    Main Methods:

    • Developed a novel stereophotogrammetric system.
    • Integrated an interactive computer graphics system for data processing.
    • Utilized digitized stereophotogrammetric pictures for 3D data acquisition.

    Main Results:

    • The system efficiently records, presents, and manipulates 3D facial data.
    • Morphological and volume changes following surgery can be accurately measured.
    • The system shows potential for optimizing multistage surgical procedures.

    Conclusions:

    • The integrated system enhances the utility of stereophotogrammetry in plastic surgery.
    • It overcomes previous accessibility and training barriers.
    • This technology offers advanced capabilities for surgical planning and outcome assessment.
