Discharge from the nose, excessive sneezing, reverse sneezing and bleeding from the nose are common symptoms seen in cats and dogs with various nasal and sinus problems. Diagnosing the cause of the problem can be difficult due to the inaccessibility of the nasal passages for direct examination. With rhinoscopy we can gain direct access to the nasal cavity to visualize the problem and take biopsy samples. During the procedure the patient is under anesthesia and a fiberoptic endoscope is passed up into the nose and through the nasal cavity. Below is an image of a normal nasal cavity.
