Rhinoscopy

 Rhinoscopy is the endoscopic study of the nasal passages. Rhinoscopy can be performed with both flexible and rigid scopes. Small-diameter scopes are utilized to adequately evaluate small dogs and cats. To perform rhinoscopy, the patient is anesthetized and the scope is gently inserted into the nasal cavity. Fluid is flushed through a protective sleeve surrounding the scope to flush away debris. The scope also magnifies the image to provide a clear view of the nasal area. Many scopes have built-in openings to allow passage of biopsy or retrieval instruments. Little patient preparation is required other than to withhold food the morning of the procedure. Most patients are discharged the same day that the procedure is performed.

The major symptoms and reasons to perform a rhinoscopy are:

1. Persistent nasal discharge '" especially when the discharge is only from one nostril (unilateral)
2. Nasal bleeding (epistaxis)
3. Persistent, uncontrolled sneezing
4. Nasal swelling
5. Noisy breathing (nasal obstruction)
6. Removing foreign matter from inside the nose
7. Reverse sneezing
