Tests and imaging
Before surgery you may need to have some tests and imaging, including blood and urine tests, a nasal endoscopy, CT scan and/or MRI. Be sure to bring your imaging with you to the hospital: having the CT scan of your sinuses is critical to a good surgical outcome.
If any issues are raised by your tests and imaging, your surgeon may have to postpone or cancel your surgery.
Medications
Your surgeon may ask you to stop taking certain medications (especially blood thinners) before your surgery. If you smoke or drink alcohol, ask your surgeon whether you should abstain from these before your surgery.
Don’t forget to mention any complementary or herbal remedies you’re taking.
