Main Methods:

  • Utilized 3D laser scan and lateral X-ray images for planning.
  • Generated soft tissue internal surface using statistical data and individual X-ray information.
  • Employed Laplacian surface deformation for real-time simulation.
  • Mapped simulation-driven deformation to soft tissue for prosthesis model generation.

Main Results:

  • The system successfully predicted postoperative appearance with high quality.
  • Patient-specific prosthesis models were generated automatically.
  • Surgeons found the planning system attractive and clinically useful.

Conclusions:

  • The developed system offers an intuitive and effective approach to rhinoplasty planning.
