Tests and procedures used to diagnose nasal and paranasal tumors include:
- Using a tiny camera to see inside your nasal cavity and sinuses. During a nasal endoscopy, a thin tube with a light and camera on the end is inserted into your nose. The camera sends pictures to a monitor that your doctor uses to look for anything unusual.
- Collecting a sample of cells for testing. If your doctor finds any abnormalities during a nasal endoscopy, special tools can be used to collect tissue samples. The samples are sent to a lab for testing.
- Imaging tests to create pictures of your nasal cavity and sinuses. Imaging techniques used to view your nasal cavity and sinuses include CT scan and MRI.
