Nasal Endoscopy

Diagnostic nasal endoscopy provides a safe and quick evaluation of the nasal passages using a nasal endoscope, a fiber-optic instrument used for examining the nasal cavity. The endoscope is slender, only 2.7-4.0 mm in diameter, and is passed easily through the nostril to allow a detailed examination of the nasal cavity and the sinuses. Dr. Zadeh may look directly through the endoscope or alternatively, a medical video camera can be attached to the endoscope, and the images may be viewed on a special video monitor. The patient may choose to view the images from his or her own examination.

Purpose:

• Nasal endoscopy provides for direct observation of the nasal passages, sinuses and other surrounding structures.
• Nasal endoscopy is used to help diagnose nasal polyps, nasal blockage, nasal tumors, recurrent sinusitis or chronic sinusitis.

Preparation:

• The patient sits in a comfortable chair.
• A topical nasal decongestant and numbing medicine may be applied to the lining of the nose by a nasal spray prior to endoscopy. The examination is easily tolerated and often can be completed without any numbing medicines at all.

Test procedure:

• Dr. Zadeh threads the endoscope into each nostril and through the nasal cavity.
• Dr. Zadeh will examine the internal structures of the nose as the endoscope is maneuvered easily through the nasal passages.

After the test:

• Once the endoscope is removed, the patient may immediately return to normal activities.

Interpretation:

• Direct observation of the nasal cavity allows Dr. Zadeh to immediately assess the patient's sinus and nasal problem. This immediate assessment allows Dr. Zadeh to discuss the results and courses of therapy with the patient during the same visit and therapy can be initiated right away.
