Nasal Endoscopy

Nasal Endoscopy Explained

Nasal endoscopy is a medical procedure in which a thin, flexible tube with a light and a camera at the end, called an endoscope, is inserted into the nostrils to examine the nasal passages and other structures within the nose. The endoscope allows healthcare providers, typically otolaryngologists (ear, nose, and throat specialists), to visualize the nasal cavity and related areas in detail.

During a nasal endoscopy, the endoscope is passed through the nostrils and advanced gently into the nasal passages. The light and camera on the endoscope transmit images to a monitor, enabling the healthcare provider to assess the condition of the nasal mucosa, nasal septum, turbinates, and other structures. This procedure is often used to diagnose and evaluate various nasal and sinus conditions.

Common reasons for performing nasal endoscopy include:

  1. Sinusitis: To assess the extent and severity of sinus inflammation.
  2. Nasal Polyps: To visualize and evaluate nasal polyps, which are non-cancerous growths in the nasal passages.
  3. Deviated Septum: To examine the nasal septum for any deviation or structural abnormalities.
  4. Allergies: To investigate the impact of allergies on the nasal passages.
  5. Chronic Nasal Congestion: To identify the cause of persistent nasal congestion.
  6. Nasal Bleeding: To locate the source of recurrent nosebleeds.
  7. Foreign Body Removal: To locate and remove foreign objects lodged in the nasal passages.

Nasal endoscopy is usually well-tolerated and can be performed in an outpatient setting. In some cases, local anesthesia or a numbing spray may be used to make the procedure more comfortable. The information obtained from a nasal endoscopy can help guide treatment decisions and interventions for various nasal and sinus conditions.
