FAQ

Common Terms & Questions About Hearing Loss

Understanding hearing loss can feel overwhelming, especially for parents. This page explains common terms, conditions, and medical words in a simple and clear way so families can make informed decisions about their child’s hearing health. Early knowledge leads to early action — and early action can change a child’s life.

Different Types of Hearing Loss

There are three main types of hearing loss:

This happens when sound cannot properly travel through the outer or middle ear.
Common causes include:

  • Ear infections
  • Fluid in the middle ear
  • Wax blockage
  • Foreign objects in the ear
  • Allergies
  • Eardrum damage
In many cases, conductive hearing loss can be treated.

This occurs when there is damage to the inner ear or the hearing nerve.
Possible causes include:

  • Birth conditions
  • Loud noise exposure
  • Infections
  • Genetic factors
  • Injury to the ear
This type of hearing loss is usually permanent but can often be managed with hearing aids or medical treatment.

Mixed hearing loss is a combination of conductive and sensorineural hearing loss.
This means there is a problem in both:

  • The outer / middle ear, and
  • The inner ear or nerve
Treatment depends on the cause and severity.

The Anatomy of the Ear

The ear has three main parts that work together to help us hear and maintain balance.
  • Auricle (Pinna) – The visible part of the ear that collects sound
  • Ear Canal – A small tube that carries sound to the eardrum
The outer ear helps guide sound into the ear.
  • Eardrum (Tympanic Membrane) – Vibrates when sound hits it
  • Ossicles – Three tiny bones that carry sound vibrations
  • Malleus (Hammer)
  • Incus (Anvil)
  • Stapes (Stirrup)
  • Eustachian Tube – Helps balance air pressure in the ear
The middle ear turns sound waves into vibrations.
  • Cochlea – Converts vibrations into signals for the brain
  • Vestibule – Helps with balance
  • Semicircular Canals – Detect head movement
  • Vestibulocochlear Nerve – Sends hearing signals to the brain
The inner ear allows us to hear and stay balanced.

What Is a Perforated Eardrum?

A perforated eardrum is a tear or hole in the thin membrane that separates the outer ear from the middle ear.
  • Ear infections
  • Injury
  • Loud sounds
  • Pressure changes
  • Pain
  • Hearing loss
  • Ear discharge
  • Ringing sound in the ear
Many perforations heal, but some need medical treatment or surgery.

What Is Eustachian Tube Dysfunction (ETD)?

The Eustachian tube connects the middle ear to the back of the nose.
  • Balance air pressure
  • Drain fluid from the ear
  • Protect the ear from infection
Normally, the tube opens when we swallow, yawn, or sneeze.
  • Ear pressure
  • Pain
  • Hearing problems
  • Frequent infections
Children often experience ETD more than adults.

What Is a Cholesteatoma?

A cholesteatoma is an abnormal growth of skin cells in the middle ear.
It is not cancer, but it can be very dangerous if not treated.

  • A cyst-like growth inside the middle ear
  • Made of trapped skin cells
  • Can slowly destroy surrounding bones
  • Repeated ear infections
  • Perforated eardrum
  • Poor ventilation in the middle ear
  • Sometimes present from birth
  • Bad-smelling discharge from the ear
  • Hearing loss
  • Ear pain
  • Dizziness or balance problems
  • Ringing sound in the ear (tinnitus)
  • Weakness in facial muscles
If untreated, cholesteatoma can cause:
  • Damage to hearing bones
  • Inner ear infection
  • Mastoid infection
  • Facial nerve damage
  • Brain infection (rare but serious)

Treatment usually requires surgery to remove the growth.
Follow-up care may include:

  • Hearing tests
  • Scans
  • Additional treatment if needed
Early diagnosis is very important.

Why Understanding These Terms Matters

Many children suffer hearing loss because symptoms are missed or misunderstood.

When parents understand the signs early, children can get help sooner.

  • Prevent permanent damage
  • Improve speech and learning
  • Avoid multiple surgeries
  • Protect a child’s future
