What are Nose & Sinus Diagnostics?

Accurate diagnosis is the first step toward effective treatment of nose and sinus conditions. At Pacific Neuroscience Institute, our ENT specialists use the latest advanced diagnostic tools and imaging techniques to thoroughly evaluate nasal and sinus health. From nasal endoscopic evaluations to high-resolution imaging and biopsies when needed, our comprehensive approach ensures precise diagnosis and personalized treatment planning for every patient.

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.

Diagnostic Imaging

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.

Biopsy

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.
