Area of Science:

  • Neurosurgery
  • Medical Technology
  • Image-guided surgery

Background:

  • Advanced surgical techniques enable extensive operations for craniofacial malformations and tumors.
  • Computer-assisted surgery (CAS) integrates patient-specific 3D imaging into surgical procedures.

Purpose of the Study:

  • To evaluate the application and benefits of CAS in complex craniofacial surgery.
  • To highlight the role of navigation systems in improving surgical outcomes.

Main Methods:

  • Utilized 3D image data interactively during surgery.
  • Employed virtual simulation software for osteotomies (bone cutting and repositioning).
  • Implemented mechanical and optoelectronic navigation systems for intraoperative guidance in over 100 cases.

Main Results:

  • CAS facilitates precise surgical planning and execution in complex anatomical regions.
  • Navigation systems provide direct intraoperative support to surgeons.
  • Extensive clinical experience (>100 applications) demonstrates system reliability.

Conclusions:

  • CAS significantly supports surgeons in diagnosis, planning, and intraoperative navigation.
  • Implementation of CAS leads to reduced operational risk and duration.
  • CAS contributes to considerable stress reduction for patients undergoing complex surgeries.
