Summary
Preoperative surgical simulation using 3D imaging and patient models enhances understanding of complex anatomy and improves surgical accuracy. This technology aids in planning complex procedures and fabricating precise reconstructive prostheses.
Area of Science:
- Neurosurgery
- Maxillofacial Surgery
- Otolaryngology
Background:
- Preoperative evaluation is critical for surgical planning, requiring analysis of pathology, adjacent structures, and anatomical risks.
- Three-dimensional (3D) imaging and patient-specific models offer advanced methods for surgical simulation.
Observation:
- A total of 481 surgical interventions across maxillofacial, sinonasal, orbital, skull base, and neurotologic regions were presurgically simulated.
- An intraoperative simulation device (Aachen Computer-Assisted Surgery System) was used in 407 cases.
- Stereolithography was employed for 7 patients to create plastic models for reconstructive surgery and prostheses.
Findings:
- Presurgical simulation using 3D imaging improved understanding of anatomical relationships and procedural feasibility.
- Intraoperative localization accuracy was enhanced.
- Reconstructive procedures and prostheses fabrication benefited from increased accuracy.
- The process provided permanent recordings and improved residency education.
Implications:
- 3D imaging and patient models significantly enhance surgical planning and execution in complex head and neck procedures.
- This technology offers a valuable tool for improving patient outcomes and surgical training.
- Despite time and cost considerations, the benefits of enhanced accuracy and understanding are substantial.
