Our ENT doctors are specialized in diagnosing a broad array of nose and sinus issues using the latest diagnostic equipment and tests.
Nasal Endoscopic Evaluation
A nasal endoscopic evaluation is one of the first steps in diagnosis prior to treatment. Using state-of-the-art endoscopes and cameras our surgeons examine the inside of the nasal and sinus cavities. In some cases, a biopsy is performed at this time. This pre-operative evaluation is important as it provides direct visualization of the intra-nasal and sinus anatomy. This evaluation is safe, brief and painless.
Imaging studies, typically magnetic resonance imaging (MRI) with gadolinium and/or a computer tomography (CT) scan are performed. Sometimes focused MRIs of the pituitary region, temporal bones, internal auditory canals or orbits may be needed to obtain better anatomical detail of a tumor. Other tests may also be needed such as angiography (typically now performed as a CT angiogram or an MR angiogram), magnetic resonance spectroscopy, positron emission tomography (PET), visual field tests, audiograms or hormonal lab tests.
For patients with masses that are visible on nasal endoscopic evaluation, often a biopsy, is performed prior to treatment. Biopsy means obtaining a small amount of the mass for microscopic examination and identification. Biopsy is not always possible or necessary and this is determined by endoscopic evaluation and imaging characteristics.
