Tinnitus is sound in the head with no external source. For many, it’s a ringing sound, while for others, it’s whistling, buzzing, chirping, hissing, humming, roaring, or even shrieking. The sound may seem to come from one ear or both, from inside the head, or from a distance. It may be constant or intermittent, steady or pulsating.
Nasal endoscopy is a procedure to look at the nasal and sinus passages. The sinuses are a group of spaces formed by the bones of your face. They connect with your nasal cavity. This is the air-filled space behind your nose.
An endoscope is a narrow tube equipped with fiberoptics that light the area. The endoscope also has a small camera that provides your doctor with images that can be projected and magnified on a screen. These images are carefully recorded for reference.
