Regular x-rays of the sinuses are not very accurate for diagnosing sinusitis.
Viewing the sinuses through a fiberoptic scope (called nasal endoscopy or rhinoscopy) may help diagnose sinusitis. This is usually done by doctors who specialize in ear, nose, and throat problems (ENTs).
However, these tests are not very sensitive at detecting sinusitis.
A CT scan of the sinuses may also be used to help diagnose sinusitis or to evaluate the anatomy of the sinuses to determine whether surgery will be beneficial. If sinusitis is thought to involve a tumor or fungal infection, an MRI of the sinuses may be necessary.
