In order to determine if a patient has sinusitis, the ENT examines the nasal cavity with the help of a rhinoscope.

With a rhinoscope, your doctor can view your nasal passages to look for upper airway causes of cough.

The best diagnostic tool available is rhinoscopy; the veterinarian will use a tool called a rhinoscope to inspect the nasal cavity.

This diagnostic study has several options, each of which involves the use of various auxiliary instruments - a nasal dilator, a nasopharyngeal mirror, and a rhinoscope.
