Summary
Utilizing 3D printed sinonasal models allows for personalized topical sinus irrigation strategies. This innovative approach visualizes optimal head positions and angles for improved sinonasal disease management.
Area of Science:
- Biomedical Engineering
- Medical Imaging
- Otolaryngology
Background:
- Topical sinus irrigations are crucial for sinonasal disease management but penetration is variable due to complex nasal anatomy.
- Predicting irrigation effectiveness is challenging due to anatomical variations and differing techniques.
Purpose of the Study:
- To propose and demonstrate a novel method using 3D printed sinonasal cavity models.
- To visualize and develop patient-specific topical sinus irrigation strategies.
Main Methods:
- Created 3D printed replicas of sinonasal cavities from CT scans using SLA 3D printing.
- Incorporated seals for a watertight connection with irrigation devices and food dye for visualization.
- Tested various head positions, injection angles, and flow rates on the 3D models.
Main Results:
- Successfully determined optimal irrigation strategies for targeted sinuses on the 3D models.
- Observed significant differences in irrigation patterns between different sinuses and pre- vs. post-surgery models.
Conclusions:
- 3D printing technology offers a potential to enhance patient care and education in sinonasal disease management.
- Enables clinicians and patients to collaboratively develop personalized irrigation strategies with visual feedback.
