Phase 3 · After
Report and plan
- 01
Before
ENT / SLT consultation
A consultant reviews your symptoms, red flags and any prior imaging — and confirms nasoendoscopy is the right step.
- 02
Before
No fasting required
Eat, drink and take medication as normal. No preparation on your part.
- 03
On the day
Topical decongestant + lidocaine
A quick spray to each nostril shrinks the mucosa and numbs the passage. Takes effect within a couple of minutes.
- 04
On the day
Flexible endoscope passed via nose
A thin flexible camera is gently passed through the nostril — most people describe it as odd rather than painful.
- 05
On the day
Structured inspection
The nasal cavity, nasopharynx, base of tongue, larynx and hypopharynx are inspected in a set sequence.
- 06
On the day
Optional stroboscopy
For voice complaints, a stroboscopic light source assesses vocal-fold vibration in real time.
- 07
After
Written report and plan
Findings are explained at the end of the appointment, with a structured written report and next-step plan.
Typical appointment: 20–30 minutes. Scope itself: around 5 minutes.
What it shows
What nasoendoscopy can find, in one visit.
The presentations nasoendoscopy is designed for — with the red-flag pathway called out separately.
-
Nasal polyps
Benign polypoid lesions in the nasal cavity, often bilateral and steroid-responsive.
-
Nasopharyngeal carcinoma
A tumour at the back of the nose — the reason a careful nasopharyngeal look is mandatory.
-
Adenoids (children)
Adenoidal hypertrophy assessed directly, avoiding the need for X-rays.
-
Base-of-tongue lesions
Lingual-tonsil hypertrophy and base-of-tongue masses visualised directly.
-
Vocal cord palsy
Unilateral or bilateral vocal-fold immobility identified and documented on video.
-
Vocal cord polyps
Benign vocal-fold lesions characterised, with a plan for voice therapy or microsurgery.
-
Laryngopharyngeal reflux
Posterior laryngeal oedema, pachydermia and inter-arytenoid changes suggestive of LPR.
-
Red flag: nasopharyngeal mass or unilateral effusion — 2WW ENT pathway
Any suspicious nasopharyngeal lesion or unilateral middle-ear effusion triggers an urgent 2-week-wait ENT referral.
Next steps
What happens after nasoendoscopy.
The eight most common next steps — from steroids and voice therapy to surgery, oncology MDT and structured follow-up.
-
Nasal steroids for polyps
First-line intranasal corticosteroids for polyp disease, often for months.
-
Surgical polypectomy
Endoscopic sinus surgery for polyps unresponsive to medical therapy.
-
Voice therapy
Specialist speech and language therapy for dysphonia, muscle tension and benign lesions.
-
Vocal cord medialisation
Injection or thyroplasty for vocal-cord palsy causing a weak, breathy voice.
-
Head-and-neck oncology MDT
Multidisciplinary review for any suspicious upper-aerodigestive lesion.
-
Adenotonsillectomy (children)
Surgical removal for obstructive adenoidal or tonsillar hypertrophy.
-
Anti-reflux therapy
PPI, alginate and lifestyle measures for laryngopharyngeal reflux, reviewed at 8–12 weeks.
-
Structured ENT follow-up
Serial nasoendoscopy to track response — the scope is easily repeated in clinic.
Red flags
When nasoendoscopy shouldn’t wait.
The nine situations that push nasoendoscopy up the queue — and, in several, straight onto the 2-week-wait head-and-neck pathway.
-
Nasopharyngeal carcinoma
A mass at the back of the nose — unilateral obstruction, epistaxis or a neck node warrant urgent scoping.
-
Vocal cord palsy
New palsy — particularly on the left — mandates cross-sectional imaging of the recurrent laryngeal nerve pathway.
-
Persistent hoarseness > 3 weeks
Unexplained hoarseness beyond three weeks in an adult is a 2-week-wait head-and-neck referral.
-
Neck lump + ENT symptoms
A persistent neck lump alongside upper-aerodigestive symptoms — always scope, always image.
-
Unilateral nasal obstruction
One-sided nasal blockage in an adult warrants direct nasopharyngeal visualisation.
-
Blood-stained nasal discharge
Recurrent unilateral epistaxis or blood-stained discharge — exclude a nasopharyngeal lesion.
-
Facial numbness
Trigeminal-distribution numbness alongside ENT symptoms — skull-base pathology must be excluded.
-
Cranial nerve palsy
Any new lower cranial nerve palsy alongside ENT symptoms is a red flag until proven otherwise.
-
Post-radiotherapy laryngeal necrosis
Late chondroradionecrosis after head-and-neck radiotherapy — requires urgent specialist review.
Reading your report
A nasoendoscopy report can look intimidating. It isn’t.
Whatever the finding, the report keeps to the same four parts.
A quiet reminder
The report is written for your doctor, not for you — and that’s normal.
If you would like us to talk you through it before your follow-up, just ask.
- 01 Header
Indication and history
Your details, the reason for nasoendoscopy, and the ENT history that shapes interpretation.
- 02 Technique
Scope, anaesthesia and stroboscopy
Which endoscope was used, whether topical anaesthesia and decongestant were given, and whether stroboscopy was added.
- 03 Findings
Nose, nasopharynx, base of tongue, larynx
Region-by-region description of the mucosa, lesions found and any dynamic vocal-fold observations.
- 04 Impression
The conclusion — read this first
Normal, benign findings, or a concrete red flag with the onward pathway — read this first.

What is nasoendoscopy?
Nasoendoscopy — also called flexible nasoendoscopy or FNE — is a 5-minute office ENT test that uses a thin flexible camera passed through the nose to inspect the nasal cavity, nasopharynx, base of tongue, larynx and hypopharynx.
-
Does nasoendoscopy hurt?
It shouldn’t. A short spray of decongestant and topical lidocaine numbs the nose. Most patients describe the passage of the scope as odd or unusual rather than painful.
-
Do I need to prepare?
No preparation — no fasting, no medication changes. You can eat, drink and drive as normal, before and after.
-
Who performs the test?
A consultant ENT surgeon, or a specialist speech and language therapist trained in flexible endoscopic evaluation of swallowing and voice.
-
Can I see the images?
Yes. Modern nasoendoscopy is video-recorded. Findings are shown to you at the end of the appointment and included with your written report.
-
When do I get my results?
The findings are discussed at the end of the appointment, with a structured written report and next-step plan to follow — typically within one to two working days.

In practice, in London
The honest picture around nasoendoscopy in London
With nasoendoscopy, the London question is usually about report turnaround and the radiologist reading it — not whether the scan is available. Public provision for nasoendoscopy is competent but constrained by capacity. Private London clinics tend to have shorter diaries and longer appointment slots, so you get the same specialists with more time. For people who’ve been going round in circles with primary care, that first proper conversation is often what shifts things.
The mechanics are straightforward: a consultant appointment, any tests done at a nearby CQC-registered site, and a written report back within a few days. London’s density of private diagnostics — Marylebone, the City, Chelsea, Canary Wharf — means most patients can find something that fits around work without a cross-town trek. For nasoendoscopy specifically, the difference between a routine report and a sub-speciality read is where private care earns its keep.
Fit matters more than people expect. For nasoendoscopy, the right consultant depends on what you actually need — a second opinion, a definitive diagnosis, a bridge into treatment, or reassurance that nothing’s being missed. We match on that, not on who has the biggest brochure. If a test isn’t the right next step, we’ll say so before you book anything.
