Preoperative tracheal resection and reconstruction simulations with patient-specific three-dimensional models

Area of Science:

• Surgical Oncology
• Medical Imaging
• Biomedical Engineering

Background:

• Three-dimensional (3D) printing technology is advancing surgical applications.
• Patient-specific organ models serve as valuable preoperative simulators for complex procedures.

Purpose of the Study:

• To describe the utility of patient-specific 3D models in planning complex tracheal resections.
• To evaluate the effectiveness of 3D printed models for preoperative simulation in tracheal surgery.

Main Methods:

• Developed patient-specific 3D models for two patients with tracheal tumors (ganglioneuroma and adenoid cystic carcinoma).
• Performed preoperative simulations (mimic operations) on the 3D models to plan surgical strategy.
• Utilized simulations to determine optimal intubation, dissection, and reconstruction approaches.

Main Results:

• Simulations identified the need for short-cuff intubation and guided the extent of dissection around the trachea and hila.
• Postoperative courses for both patients were uneventful, with no anastomotic or pulmonary complications.
• 3D models facilitated accurate surgical preparation and selection of optimal strategies.

Conclusions:

• Patient-specific 3D printed models are effective for preoperative simulation in complex tracheal resection and reconstruction.
• Mimic operations using 3D models enhance surgical planning, accuracy, and confidence.
• This approach contributes to improved patient outcomes in challenging tracheal surgeries.
