Summary
Patient-specific 3D models of the larynx and trachea aid complex surgeries. These 3D printed models improve surgical planning and team training for laryngotracheal procedures.
Area of Science:
- Otolaryngology
- Surgical Innovation
- Medical Imaging
Background:
- Complex laryngotracheal surgeries like slide laryngotracheopexy and extended partial laryngectomy require precise preoperative planning.
- Conditions include cricotracheal stenosis and T2-T3 glottic tumors.
Purpose of the Study:
- To present the digital workflow and application of patient-specific 3D laryngotracheal models.
- To demonstrate the utility of 3D printing in surgical planning and training for complex airway surgeries.
Main Methods:
- Utilized digital/virtual 3D techniques and Additive Manufacturing (AM) to create CT-based 3D models.
- Developed patient-specific 3D printed models of the larynx and trachea.
Main Results:
- Successfully applied 3D models in the preoperative planning of three complex laryngotracheal surgeries.
- 3D models facilitated surgical team preparation and provided a platform for training.
Conclusions:
- Patient-specific 3D laryngotracheal models offer high-fidelity anatomical representations.
- These models enhance surgical rehearsal, training, and patient communication.
- Demonstrated potential for broader clinical implementation of 3D modeling in airway surgery.
