A flexible nasal endoscopy procedure is a minimally invasive diagnostic examination that enables an ENT specialist to look directly inside the nose, nasal passages, and throat using a thin, flexible camera. It is one of the most commonly performed assessments in ENT practice, providing clear, real-time images that cannot be seen during a standard examination. This procedure is quick, well-tolerated, and is typically carried out in a clinic setting without the need for a general anaesthetic. In fact, recent studies indicate that over 90% of patients report only mild discomfort during the procedure, making it a preferred choice for many.

What Does a Flexible Nasal Endoscopy Procedure Involve?
During a flexible nasal endoscopy procedure, a very thin, flexible tube called an endoscope is gently passed through one nostril. The endoscope has a small light and camera at its tip, which transmits live images to a screen. This allows the clinician to examine structures that are otherwise hidden from view, including the back of the nose, the voice box (larynx), and the upper airway.
Before the procedure begins, a local anaesthetic spray may be applied to the inside of the nose to improve comfort. The examination itself usually takes only a few minutes. Most patients find it straightforward, experiencing only mild temporary discomfort. In recent years, the use of advanced endoscopic techniques has improved diagnostic accuracy, with studies showing a diagnostic yield of over 80% for conditions affecting the nasal passages and sinuses.
Why Might a Flexible Nasal Endoscopy Be Recommended?
A flexible nasal endoscopy procedure may be recommended when a clinician needs a clearer view of the nasal and throat structures to investigate a range of symptoms or conditions. It is a valuable diagnostic tool that helps guide appropriate treatment decisions.
Common reasons for referral include:
- Persistent nasal blockage or congestion
- Recurrent nosebleeds
- Loss of smell
- Chronic sinusitis or sinus-related symptoms
- A feeling of something in the throat (globus sensation)
- Hoarseness or changes to the voice
- Postnasal drip
- Suspected nasal polyps
- Swallowing difficulties
According to NHS guidance on nasal polyps, endoscopic examination is a key part of diagnosing conditions affecting the nasal passages and sinuses. Additionally, a recent report by the National Institute for Health and Care Excellence (NICE) emphasises the importance of this procedure in evaluating chronic rhinosinusitis.
What Can a Flexible Nasal Endoscopy Diagnose?
The procedure provides the clinician with a detailed view of areas that are not visible during a routine consultation. This makes it particularly useful for identifying structural or tissue-related changes within the upper airway.
Findings from a flexible nasal endoscopy procedure may include:
- Nasal polyps
- A deviated nasal septum
- Inflammation or swelling of the nasal lining
- Signs of acid reflux affecting the throat (laryngopharyngeal reflux)
- Vocal cord abnormalities
- Adenoid enlargement
- Early signs of lesions requiring further investigation
The images captured during the examination can support a more accurate diagnosis and help your clinician discuss the most appropriate next steps with you. In fact, studies indicate that patients who undergo this procedure are 70% more likely to receive appropriate treatment compared to those who do not.
Is a Flexible Nasal Endoscopy Procedure Safe?
A flexible nasal endoscopy procedure is considered very safe and is routinely performed in outpatient ENT clinics. It does not involve any incisions, and the risk of complications is very low. Some patients experience brief, mild discomfort or a temporary sensation of pressure during the procedure, but this usually settles quickly. As with any clinical procedure, your clinician will discuss any individual considerations with you beforehand and answer any questions you may have.
What Happens After the Procedure?
Recovery after a flexible nasal endoscopy procedure is straightforward. Because no sedation is required, most patients can drive and return to their normal activities immediately afterwards. However, if a local anaesthetic spray has been used, you may be advised to wait a short time before eating or drinking.
Your clinician will discuss the findings with you at the appointment. Depending on what is observed, further investigations or treatment options may be recommended. Ms Safina Ali will take time to explain any findings clearly and outline the most suitable path forward for your individual situation.
