Planning
Settings
- A low-dose CT without contrast is generally sufficient in suspected acute sinusitis.
- Normal radiation dose is indicated in suspected chronic sinusitis.
- Imaging without and with IV contrast is indicated in a suspected facio-maxillary abscess.
Evaluation
- Mucus content in paranasal sinuses, particularly the ostiomeatal complex.
Ostiomeatal complex (green area)
- Any sclerotic thickening of the walls of the sinuses, indicating chronic sinusitis.
- Any abnormal protrusion of teeth into the maxillary sinuses.[1]
- Any mucus or fluid in the outer or middle ear.
