Nasal endoscopy can be a valuable diagnostic tool for determining the nature of chronic (ongoing) nasal and sinus problems. It provides a very detailed picture of nose and sinus function.

Although considered very safe, several risks or complications can occur on rare occasions. These include:

• Infection. An infection may develop for various reasons and may require treatment with antibiotics. Drainage that becomes foul smelling, thick or colorful after the procedure may be an indication that an infection has developed or is ongoing. Patients who suspect an infection should contact their physician immediately.
  
  
• Bleeding. Bleeding is not unusual, but excessive bleeding is rare.
  
  
• Cerebrospinal fluid leak. In extremely rare cases, a physician may accidentally make an opening between the sinuses and the brain. The fluid around the brain can then leak into the nasal cavity and out from the nose. This opening increases the patient’s risk of developing meningitis (brain infection).
