When a doctor looks in your ear with an otoscope, they see a light-gray, shiny eardrum (tympanic membrane) with a visible middle bone (malleus) and a triangular "cone of light" reflecting the otoscope's beam, indicating a healthy, clear canal, but infection can make it red, bulging, or filled with fluid, while other issues might show pus or damage.
The only way to know for sure if your child has one is for a doctor to look inside her ear with a tool called an otoscope, a tiny flashlight with a magnifying lens. A healthy eardrum (shown here) looks sort of clear and pinkish-gray. An infected one looks red and swollen.
Using a speculum that's too large or small may cause discomfort or limit visibility. Choose the largest size that fits comfortably into the canal. This can cause pain or injury. Insert the otoscope gently and avoid pushing past resistance.
In this examination, the doctor looks into the ear using an instrument called an otoscope. The otoscope consists of a handle and a cone-shaped attachment called an ear speculum, which contains a tiny lamp and is inserted into the ear canal.
Tests that study how well the inner ear is working include: Electronystagmogram or videonystagmography (ENG or VNG). These tests measure balance by studying eye movement. One part of the test looks at eye movement while your eyes follow a target.
Three-finger test: Keep one finger at cymba conchae, second finger over posterior border of mastoid and third finger at mastoid tip. Maximum tenderness under first finger signifies tenderness over suprameatal triangle.
An otoscope allows physicians to examine the condition of the eardrum, identify signs of inflammation in the ear canal, and detect earwax buildup. It is also frequently used in clinics to identify foreign objects and fungal infections at early stages.
Other related conditions include:
A hearing test helps identify patterns of hearing loss, while imaging like MRI or CT can detect whether a tumor is present. Together, these evaluations help doctors to accurately distinguish between the two conditions.
The symptoms of an ear infection usually start quickly and include:
Ear Infection Stages
Stage 3: Chronic Otitis Media - This stage involves persistent fluid buildup in the middle ear and may result in long-term hearing loss if left untreated.
Don't try to remove the object. Seek medical help. There is a slight risk of damaging the eardrum if the otoscope is inserted too far into the ear canal.
How is an object in the ear diagnosed? Your doctor will look inside your ears with a light while you stay very still. They will ask how your ears feel. If a child has an object in their ear, the doctor will ask if anyone saw what it was.
The ear drum is located about 1.5 cm inside the skull at the end of the external auditory canal. The canal is rigid (surrounded by bone and cartilage), but it is not straight. The canal often has ear wax (medical term, cerumen) that either partially or completely obstructs the view of the eardrum.
Most of the time symptoms affect 1 ear and include:
Unlike other types of ear infections, inner ear infections can't be properly diagnosed with a visual examination. A comprehensive assessment is necessary to rule out other health conditions, such as stroke, migraine headaches or Meniere's disease, which all share similar symptoms.
Ear pain red flags needing urgent care include severe pain with headache, facial drooping, fever, swelling or redness behind the ear (mastoiditis), ear discharge, hearing loss, dizziness, or weakened immune system/diabetes, as these suggest serious infections or complications like mastoiditis or cranial nerve issues. Persistent pain, one-sided hearing loss, or symptoms not improving with treatment also warrant prompt medical attention.
Middle Ear Fluid (Otitis Media with Effusion)
The condition is also called a silent ear infection because many children have no symptoms. Some children, though, may rub their ear or experience mild pain, sleep disturbances, unexplained clumsiness, muffled hearing, or delays in language and speech development.
You may have ear wax blockage if you feel a full-like sensation, or plugged-up clogged feeling may be present when there is a blockage. Itching, tinnitus (ringing in the ears), and sometimes dizziness may also be symptoms/signs of too much ear wax.
A dull or absent light reflex from the eardrum may be a sign of a middle ear infection or fluid. The eardrum may be red and bulging if there is an infection. Amber liquid or bubbles behind the eardrum are often seen if fluid collects in the middle ear. Abnormal results may also be due to an external ear infection .
Symptoms and Causes
The 60/60 rule for hearing is a guideline to prevent noise-induced hearing loss: listen to personal audio devices at no more than 60% of the maximum volume for no longer than 60 minutes at a time, then take a break. This helps protect your ears from damage by keeping sound levels moderate and allowing for rest, especially important with headphone/earbud use.
During an ear exam, your ENT doctor will use a specialised tool called an otoscope to thoroughly check the outer canal of your ear and the eardrum. He will place the tip of the otoscope into your ear and shine a light into your ear canal, down to your eardrum.
In the finger rub test, the examiner rubs his or her fingers together near the patient's ear and asks the patient whether they have heard the sound. This is a crude and easy test for screening for hearing loss. Screening tests should be easy and have high sensitivity.
