This study introduces a two-stage approach to reduce risks in craniofacial surgery. It combines preoperative risk modeling with intraoperative guidance using a head-mounted display for enhanced surgical accuracy.

Area of Science:

  • Medical Engineering
  • Surgical Innovation
  • Computer-Aided Surgery

Background:

  • Craniofacial surgery carries inherent risks, often stemming from the complexity of anatomical structures and the challenges of precise surgical execution.
  • Current surgical practices may lack integrated systems for real-time risk assessment and mitigation during procedures.
  • The absence of preoperative planning data in the operative field during surgery can compromise accuracy and increase potential complications.

Purpose of the Study:

  • To present a novel two-stage concept for risk reduction in craniofacial surgery.
  • To develop and apply a preoperative risk modeling technique for surgical planning.
  • To implement an intraoperative risk reduction strategy utilizing advanced visualization technology.

Main Methods:

  • Development of a risk model by superimposing isotropic risk potential and anisotropic tissue field constituents.
  • Application of the risk model for preoperative planning and simulation, including determination of low-risk surgical access paths.
  • Integration of a see-through head-mounted display (HMD) for intraoperative guidance.
  • Utilization of optical tracking for the surgeon and patient, coupled with registration of preoperative data to the patient.
  • Visualization of planning data within the HMD to enhance surgeon accuracy.

Main Results:

  • The proposed risk model effectively identifies and visualizes potential risk sources preoperatively.
  • The two-stage approach aims to minimize risks by optimizing surgical planning and providing real-time intraoperative data.
  • The head-mounted display system facilitates the immersion of preoperative data into the surgical field, aiding in maintaining accuracy.

Conclusions:

  • The presented two-stage concept offers a comprehensive strategy for mitigating risks in craniofacial surgery.
  • Preoperative risk modeling and intraoperative guidance via HMD represent a significant advancement in computer-aided surgery.
  • This approach has the potential to improve patient safety and surgical outcomes in complex craniofacial procedures.
