Eustachian tube function testing, tympanometry, Valsalva, Toynbee and ETDQ-7 to characterise ear pressure problems.
A structured battery that measures how well the eustachian tubes are working. It combines tympanometry, Valsalva and Toynbee manoeuvres, otoscopy, and the ETDQ-7 questionnaire. It picks up eustachian tube dysfunction — the cause of ear-pressure symptoms, glue ear, and barotrauma.
Key facts
- 01
Definition
A structured set of tests that measures how well the eustachian tubes are working.
- 02
Tympanometry pattern
Classifies middle-ear pressure and compliance as Type A (normal), Type B (effusion) or Type C (negative pressure).
- 03
Valsalva and Toynbee
Bedside manoeuvres that show whether the eustachian tube opens on demand.
- 04
ETDQ-7 questionnaire
A validated 7-item score — ≥ 14.5 supports a diagnosis of chronic eustachian tube dysfunction.
- 05
Complements the clinical exam
Sits alongside otoscopy and flexible nasoendoscopy of the nasopharynx.
- 06
Guides intervention
Determines who benefits from balloon eustachian tuboplasty and who does not.
How it is done
From consultation to plan — what happens, in order.
A single consultant appointment covers the whole battery — otoscopy, tympanometry, bedside manoeuvres, the ETDQ-7 and nasoendoscopy — followed by a written report.
- 01
Before
ENT consultation
A consultant otologist takes a targeted history — ear-pressure symptoms, barotrauma, effusion, cleft palate, radiotherapy.
- 02
On the day
Otoscopy
Direct inspection of the tympanic membrane looking for retraction, effusion or perforation.
- 03
On the day
Tympanometry
A quick, painless probe measures middle-ear pressure and compliance to classify the tympanogram.
- 04
On the day
Valsalva and Toynbee manoeuvres
Repeat tympanometry after each manoeuvre to demonstrate active eustachian tube opening.
- 05
On the day
ETDQ-7 questionnaire
A validated 7-item symptom score completed with the clinician — a total ≥ 14.5 supports chronic ETD.
- 06
On the day
Nasoendoscopy
Flexible endoscopy of the nasopharynx to inspect the tubal orifice and exclude a mass.
- 07
After
Written report and plan
A consultant letter with pattern of dysfunction, ETDQ-7 score and a plan — medical, autoinsufflation, grommets or balloon tuboplasty.
What it shows
The patterns the test can reveal.
Eustachian tube function testing answers a specific question — is the tube opening on demand, is the middle ear ventilated, and is there a mechanical or mucosal cause driving the symptoms.
-
Type A tympanogram (normal)
Normal middle-ear pressure and compliance — makes eustachian tube dysfunction unlikely as the cause.
-
Type C (negative middle-ear pressure)
Peak pressure shifted to the negative side — the hallmark of eustachian tube dysfunction.
-
Type B (effusion)
A flat trace — consistent with fluid in the middle ear (otitis media with effusion).
-
Baro-challenge dysfunction
Symptoms on flying, diving or altitude change with abnormal manoeuvre response.
-
Chronic ETD (ETDQ-7 ≥ 14.5)
A validated score threshold that supports the diagnosis of chronic obstructive eustachian tube dysfunction.
-
Patulous ET dysfunction
An abnormally open tube — autophony and breath-synchronous tympanic membrane movement.
-
Nasopharyngeal mass
Nasoendoscopy identifies a lesion at the tubal orifice that mechanically obstructs the tube.
-
Red flag: unilateral effusion in an adult — investigate for nasopharyngeal carcinoma
A unilateral middle-ear effusion in an adult mandates urgent nasoendoscopy and, if indicated, cross-sectional imaging.
Treatment and next steps
What follows a positive test.
The results shape a stepwise plan — medical therapy first, then autoinsufflation, then targeted intervention for the minority who need it.
-
Nasal steroids and saline
First-line medical therapy — intranasal corticosteroid spray with saline irrigation to reduce mucosal oedema at the tubal orifice.
-
Autoinsufflation (Otovent)
A nasal balloon device used several times a day — evidence supports it in adults and children with chronic ETD.
-
Grommets for chronic effusion
Ventilation tubes to bypass a persistently dysfunctional eustachian tube — the workhorse for persistent effusion.
-
Balloon eustachian tuboplasty (BET)
Endoscopic balloon dilatation of the cartilaginous eustachian tube — indicated for chronic obstructive ETD (ETDQ-7 ≥ 14.5) not responding to medical therapy.
-
Adenoidectomy (paediatric)
Removes adenoidal tissue that obstructs the tubal orifice in selected children with recurrent effusion.
-
Allergy management
Antihistamines, intranasal steroids and allergen avoidance where co-existing allergic rhinitis is driving the problem.
-
CPAP if OSA-related
Continuous positive airway pressure where obstructive sleep apnoea is contributing to eustachian tube pathology.
-
Structured ENT follow-up
Repeat ETDQ-7 and tympanometry at defined intervals to demonstrate objective response and guide escalation.
Red flags
When ear-pressure symptoms need urgent ENT input.
Most eustachian tube dysfunction is benign. These are the features that change the pace of investigation.
-
Adult unilateral effusion
Unilateral middle-ear effusion in an adult raises the differential of nasopharyngeal carcinoma — urgent nasoendoscopy is mandatory.
-
Blood-stained nasal discharge
Any bloody or blood-stained nasal discharge in the context of ETD warrants urgent ENT review.
-
Persistent unilateral nasal obstruction
One-sided nasal blockage that does not resolve — a red flag for a nasopharyngeal lesion.
-
Cranial-nerve palsy
Any new cranial-nerve deficit alongside ear symptoms warrants urgent imaging and ENT input.
-
Cervical lymphadenopathy
Unexplained neck lumps — investigate for nasopharyngeal or head-and-neck malignancy.
-
Post-radiotherapy ETD
A history of head-and-neck radiotherapy predisposes to intractable ETD and effusion — specialist ENT input is required.
-
Cleft palate-related ETD
Cleft palate is associated with lifelong eustachian tube dysfunction — managed within multidisciplinary cleft services.
-
Recurrent facial pain
New or recurrent facial pain with ETD may indicate sinus, dental or neuralgic pathology.
-
Sensorineural hearing loss with ETD
Sensorineural (not conductive) hearing loss with eustachian tube symptoms warrants full audiological and imaging work-up.

Frequently asked
Everything patients ask about eustachian tube function testing.
Quick answers on tympanometry patterns, the ETDQ-7 score, nasoendoscopy, and when balloon eustachian tuboplasty comes in.
-
What is a eustachian tube function test?
It is a structured battery of tests — otoscopy, tympanometry, Valsalva and Toynbee manoeuvres, the ETDQ-7 questionnaire and flexible nasoendoscopy — that together objectively characterise how well the eustachian tube is working.
-
What does a Type C tympanogram mean?
A Type C tympanogram shows negative middle-ear pressure — the peak of the trace is shifted to the negative side. It is the classic pattern of eustachian tube dysfunction and, in the right clinical context, supports the diagnosis.
-
How is the ETDQ-7 questionnaire scored?
ETDQ-7 is a validated 7-item symptom questionnaire, each item scored 1–7, giving a total of 7–49. A mean score ≥ 14.5 (total ≥ 14.5) supports the diagnosis of chronic obstructive eustachian tube dysfunction.
-
Do I need a nasoendoscopy as part of the test?
Yes — flexible nasoendoscopy of the nasopharynx is a standard component. It inspects the tubal orifice and, importantly, excludes a nasopharyngeal mass, particularly in adults with unilateral middle-ear effusion.
-
What is balloon eustachian tuboplasty (BET) and who is it for?
BET is an endoscopic day-case procedure in which a small balloon dilates the cartilaginous eustachian tube. It is indicated for chronic obstructive ETD confirmed on tympanometry and an ETDQ-7 ≥ 14.5, in patients who have not responded to at least three months of medical therapy.
-
Why is a unilateral effusion in an adult a red flag?
A one-sided middle-ear effusion in an adult can be the presenting sign of a nasopharyngeal carcinoma obstructing the eustachian tube. Every such patient needs urgent nasoendoscopy, and cross-sectional imaging if any abnormality is seen.

In practice, in London
How eustachian tube function test tends to unfold when you go private
With eustachian tube function test, the London question is usually about report turnaround and the radiologist reading it — not whether the scan is available. On the NHS, eustachian tube function test typically sits behind a triage step and a wait that can stretch from a few weeks into months. In London’s private sector, the same appointment often lands within days. That speed matters when symptoms are disrupting work, sleep, or a plan you’d already committed to — and it’s the single most common reason people call us in the first place.
A typical private booking for eustachian tube function test in London starts with a consultant conversation — sometimes in person on Harley Street or Marylebone, sometimes on video if that suits better. Any imaging or diagnostics happen at a nearby CQC-registered facility, and reports usually land within 24 to 72 hours. The whole loop, from first call to written report, is often done inside a fortnight. For eustachian tube function test specifically, the difference between a routine report and a sub-speciality read is where private care earns its keep.
We’re careful about what a private pathway for eustachian tube function test can and can’t promise. It can compress a wait, put you in front of a subspecialist quickly, and get a proper report in your hands within a week. It can’t rewrite what the imaging or the bloods say. Setting that expectation up front tends to make the whole experience less stressful.
