You might need a nasal endoscopy if your healthcare provider needs more information about problems such as:
1. Nasal congestion
2. Nasal blockage
3. Nasal and sinus infection (rhinosinusitis)
4. Nasal polyps
5. Nasal tumors
6. Nosebleeds
7. Decreased or loss of ability to smell
8. Cerebrospinal fluid (CSF) leak
The endoscopy can show certain details, such as the site of bleeding and swelling of nasal tissue. It can also be used to look at a growth that might be a benign nasal polyp or cancer.
In some cases, a nasal endoscopy can be used as a treatment. For example, it may be done on a child to remove a foreign object from their nose.
Your healthcare provider might also advise endoscopy to see how treatment for a nose or sinus problem is working. For example, it can show if nasal polyps have shrunk.
Rhinosinusitis (inflammation of the nasal and sinus linings) is one of the most common reasons for nasal endoscopy. You may have symptoms such as nasal blockage, yellow or greenish fluid from your nose, and facial pain. Your healthcare provider can use the endoscope to look for swelling and polyps. They may collect pus from the infected area. This can help show what is causing an infection and how best to treat it.
A healthcare provider may use a nasal endoscope to do minimally invasive surgery. This is done in a hospital or surgery center. It can treat conditions such as sinus infection, nasal polyps, and nasal tumors. The surgery is done with very small tools and does not need an external cut (incision).
