Summary
3D printing aids in planning sinus irrigation for better outcomes. Specific head positions and the backfill technique significantly improve irrigant penetration to targeted sinuses.
Area of Science:
- Otolaryngology
- Medical Imaging
- Biomedical Engineering
Background:
- Topical sinus irrigation is crucial for managing sinonasal diseases.
- Irrigant penetration to sinuses can be unpredictable.
- 3D printing offers a potential solution for optimizing irrigation planning.
Purpose of the Study:
- To investigate the utility of 3D printing for planning topical sinus irrigation.
- To evaluate the impact of different head positions and irrigation techniques on sinus penetration.
Main Methods:
- Eight patient-specific 3D-printed models were created from CT scans.
- Sinus irrigations were performed using a squeeze bottle in four distinct head positions.
- Both conventional (upper nostril) and backfill (lower nostril) irrigation techniques were tested.
Main Results:
- Significant variations in sinus penetration were observed based on head position.
- The 90° to-the-side and 90° forward positions were most effective for irrigation.
- Backfill technique showed superiority over conventional method in side-tilted positions.
Conclusions:
- Head position and irrigation technique critically influence sinus irrigation effectiveness.
- The backfill technique appears to enhance irrigant delivery to sinus ostia.
- 3D printing serves as a valuable tool for guiding personalized sinus irrigation strategies.
