Summary
Sinus anatomical features like volume and shape are linked to chronic rhinosinusitis (CRS) risk. These findings can help assess CRS development and guide clinical management strategies.
Area of Science:
- Otolaryngology
- Medical Imaging
- Artificial Intelligence
Background:
- Anatomical variations in paranasal sinuses are implicated in chronic rhinosinusitis (CRS) development.
- Understanding these morphological differences is crucial for effective clinical management and risk assessment.
Purpose of the Study:
- To investigate the correlation between sinus morphological features and the risk of CRS onset.
- To develop predictive models for CRS risk based on sinus anatomy.
Main Methods:
- A multicenter study involving 716 CRS patients and 115 controls.
- Automated sinus segmentation using the deep learning model nnU-Net v2.
- Morphological feature extraction via PyRadiomics and risk prediction using logistic regression, random forest, and MLP models.
Main Results:
- CRS patients showed larger sinus volumes, surface areas, and diameters, with lower sphericity compared to healthy individuals.
- A CRS risk prediction model using 20 indicators achieved AUCs of 0.884-0.890.
- No significant morphological differences were found between eosinophilic CRS (eCRS) and non-eosinophilic CRS (NeCRS) subtypes.
Conclusions:
- Specific sinus morphological features are significant indicators for assessing CRS risk.
- The identified features can aid in predicting the likelihood of developing chronic rhinosinusitis.
- Sinus morphology does not differentiate between eCRS and NeCRS, suggesting other factors are involved in subtype development.
