Nasal endoscopy: detailed examination of the nose and sinus drainage areas
Nasal endoscopy uses a slim flexible or rigid telescope to look beyond the front of the nose. It can reveal inflammation, polyps, discharge, bleeding sites, structural narrowing and other findings that may not be visible with a basic examination.
Usually a brief office-based diagnostic procedure. A topical decongestant or local anesthetic spray may be used for comfort when appropriate.
Why this procedure may be recommended
Endoscopy may be useful when symptoms are persistent, recurrent or not fully explained by the front-of-nose examination.
- Persistent nasal obstruction
- Chronic or recurrent sinus symptoms
- Reduced smell
- Frequent nosebleeds
- Post-nasal drip
- Suspected polyps
- Assessment after nasal or sinus treatment
Before the procedure
Tell the clinician about recent nosebleeds, anticoagulant medicines, previous nasal surgery and significant nasal sensitivity. Most patients do not need special fasting for a diagnostic office endoscopy.
- Bring relevant scan reports or previous ENT notes
- Continue regular medicines unless specifically told otherwise
- Ask questions about the reason for the procedure before it starts
What happens during the procedure
- PreparationThe nose is examined and a topical spray may be used to reduce swelling or improve comfort.
- Endoscopic examinationThe telescope is gently passed through the nasal cavity while key structures are inspected.
- Review of findingsImages or findings may be explained immediately and linked to the treatment plan.
Comfort, recovery and aftercare
Most people return to normal activities shortly afterward. Temporary numbness, a bitter taste from spray, mild irritation or a small amount of spotting can occur.
- Avoid forceful nose blowing immediately if the nose feels irritated
- Follow any specific instructions if a biopsy or additional procedure was performed
- Contact the clinic if significant bleeding or severe symptoms occur
Benefits, limitations and alternatives
The main benefit is direct visualization. It can make the diagnosis more precise and help avoid unnecessary imaging or treatment in some situations.
Depending on the problem, alternatives or additional tests may include anterior nasal examination, CT imaging, allergy assessment or observation.
Possible risks and important considerations
Diagnostic nasal endoscopy is generally well tolerated, but temporary discomfort, sneezing, watering of the eyes, light bleeding or a faint feeling can occur. Individual risks are discussed when relevant.
Follow-up
The endoscopy findings are incorporated into the overall care plan. Follow-up depends on the diagnosis and whether medical treatment, imaging or another procedure is required.
Frequently asked questions
Is nasal endoscopy painful?
Most people describe pressure or brief discomfort rather than significant pain. Topical spray can be used when appropriate.
How long does it take?
The examination itself is often only a few minutes, although the full consultation takes longer.
Can it diagnose sinus problems?
It can show inflammation, discharge, polyps and drainage areas, but CT imaging is sometimes needed for a more complete sinus assessment.
Discussing suitability
If nasal endoscopy is recommended, the reason for it and how the result will influence treatment should be explained before the procedure.
