A nasal endoscopy is a procedure that uses a flexible tube to explore hard-to-reach areas of the nasal passage. It is usually performed by ENT specialists or allergists and can be done in the office. An angled telescope allows for a more detailed assessment of the patient’s sinuses and nasal cavity. Most patients experience little discomfort during the procedure.
A nasal endoscopy is a procedure that uses a flexible tube known as an endoscope to explore hard-to-reach areas of the nasal passage such as the larynx, oropharynx, and nasopharynx. This procedure is usually performed by ear, nose and throat (ENT) specialists or allergists. A nasal endoscopy is also known by a variety of other names such as rhinolaryngoscopy, rhinoscopy, or nasopharyngoscopy.
The medical device used during the examination is known as a nasal scope with the procedure itself given the technical name of diagnostic nasal endoscopy. The telescope is generally less than 4 millimeters in diameter, making it easy for the ENT specialist to direct it through the patient’s nostrils and examine the sinuses and nasal passages. There are nose scopes which give the specialist the required view directly from the tip which allows for straight vision. There are also telescopes that allow the specialist to view the nasal passage at an angle.
Angled telescopes allow the specialist to see around corners. This is extremely important because regular nasal examination is very limited. Telescopes with an angled view allow for a more detailed assessment of the patient’s sinuses and nasal cavity.
ENT doctors are also known as otolaryngologists and commonly perform nasal endoscopy on patients in the office rather than in the hospital. The doctor looks directly through the telescope and performs a quick examination. If a more detailed evaluation is needed, a tiny video camera can be attached to the telescope that allows the doctor to view the images processed by the oscilloscope on a video monitor. It is also possible to record the examination on a digital image archive; patients can view footage of what was seen during the nasal endoscopy if they wish.
Most patients experience little discomfort during a nasal endoscopy. The ENT doctor usually sprays the patient’s nostrils with an anesthetic. Then the tube will be gently lowered into your nose and down your nasal passages
Your doctor may also choose to use some other medical tools during nasal endoscopy. These can be used in the office and usually resemble a pair of scissors except there is a long crooked end designed to reach into corners. These particular instruments are often used in conjunction with angled nose scopes.
