Nasal endoscopy basically allows the ENT surgeon in Abu Dhabi to see what he or she is unable to see in a basic ENT examination. It gives the doctors a magnified view of the nasal and sinus passages, something which is not possible for their naked eyes to give. The procedure of nasal endoscopy has become very common, and it is one of the best diagnostic tools available with the doctors for the evaluation of the nasal mucosa, nasal pathology and sinonasal anatomy. It is a minimal invasive procedure.
The nasal endoscope in Abu Dhabi used in the procedure is a medical device which consists of thin, but rigid tube. This tube is fitted with fiberoptic cables which help in bringing in the light. A video camera and a light source are attached to this endoscope so as to project magnified images on a screen which is again connected to the video camera. With the help of this camera, the images from the inside of a patient are captured and recorded for further analysis and treatment purposes. The width of this tube is kept between 2.7 mm to 4 mm, which ensures that the endoscope is slender enough to easily pass through the nasal passages of the patient and allow complete nasal and sinus examination.
Procedure For Nasal Endoscopy
The first step in the procedure is to spray medicine inside the nose. This spray will reduce the swelling in the area, and at the same time also make that area numb. As a result of this, the patient does not feel any sort of pain or discomfort during the entire procedure. However, the patient remains conscious, and therefore, he or she may be aware of the tube being pushed inside, and this sensation can cause a slight discomfort. Next, the thin endoscopy tube, along with the light and the camera will be inserted inside the nose. Depending on the type of penetration required, the tube selected for the purpose can be either flexible or rigid. The tube will be pushed further inside the nose, and up in the sinuses. With the help of the images viewed on the screen connected to the camera placed on the tube, the doctor will make his or her analysis, and the recording of the same would be saved for further references. Once the images have been captured, the tube would be removed slowly and the procedure would get completed. On completion, there might be a little nose bleed or drain, but this is nothing to be worried about, and the doctor performing the nasal endoscopy will take care of the same.
Risks Associated With Nasal Endoscopy
As mentioned before, nasal endoscopy is a minimal invasive procedure, and therefore, there are no risks involved in the same. However, in spite of the spray medicine given to the patients for making the area numb, there are some patients who experience a lot of pain during and after the procedure. The tissues inside the nose and the sinus can also get damaged during endoscopy. However, none of the risks of this procedure are something that a patient should be worried about or would have a long term effect on the health of the patient.
