What parents should know about Microtia



Microtia is a congenital ear deformity that is sometimes called microtia of the ear. Even though microtia is not a common birth defect, it is not so unusual as to be considered "rare". Microtia may be found in about 1 in 8,000 children, so many ENT doctors have experience with this birth defect. Let's take a closer look at the basic facts about microtia.

The word microtia is derived from Latin words that literally mean "little ear", and this describes the condition of microtia very directly. It is an ear deformity in which the external ear has not formed properly, or perhaps not at all, so it appears to be a tiny ear. The cause of this birth defect is not known, but it is known that there is nothing that parents did to cause it or could have done to prevent it. So if you have a child with microtia, do not be concerned about your role in this congenital ear deformity.

Microtia of the ear is often accompanied by hearing loss, as the opening to the ear canal is not as open as in a normally developed external ear. The ear canal itself may also be slightly misshapen, adding to the hearing loss. All children are giving a hearing test at birth, which is usually very simple and comes back normal. For children with microtia, this hearing test is important as it documents the amount of hearing loss that the children have right after birth. Parents should pay attention to these numbers and keep track of them as the child grows. Additional hearing tests will be able to be compared to this initial test to see if any additional hearing loss occurs over time. As a child grows, the shape of their ear and ear canal may change over time, and the hearing loss can change as well. Having the numbers from the initial hearing test will be useful to track any changes in their hearing.

Since microtia often occurs in only one ear, a child who has microtia can have perfect hearing in their other ear. Nonetheless, learning language may be a little more difficult for this child, so parents of children with microtia should spend some extra time working on their children's language skills. Language is composed of some very subtle sound distinctions, so a child with some hearing loss may need to focus more than other children do in order to learn language. Since language brings us together far more than physical appearance, there is no reason for a simple ear deformity to reduce a child's ability to play with other children and communicate just as well as any child does.

As a child with microtia matures, it may be possible to have ear reshaping surgery. While not necessary, this can make the ear deformity less noticeable, and it may also reduce the child's hearing loss. Parents of children with microtia will of course be visiting an ear, nose, and throat doctor on a regular basis to track the child's hearing loss, so this doctor can keep them informed on the possibility of ear reshaping surgery. Some cases will be handled more easily than others, so consult with an ENT doctor before making a decision.

ENT specialists lay down the treatment options for hearing loss


Hearing loss is the most common ear problem in human beings today. WHO predicts that in India, more than 75 million individuals will be suffering from significant auditory impairment by the end of 2020. These astounding numbers amount to severe loss in productivity, both physical and economical. Unfortunately, even larger numbers are linked to milder degrees and unilateral (one sided) hearing loss.

Types of hearing loss

  1. Conductive Hearing Loss occurs because of difficulty in the middle ear. In a normal ear, the sound hits on an integral eardrum. The increase in movement is backed up by three small bones, working simultaneously in which the third bone works as a piston to deliver the increased vibrations to the fluid system of the inner ear. Fluid in the ear, eardrum tear, and damage to the working of the three bones may cause hearing loss. If the inner ear is enthused directly by the nerves, hearing organ and hearing is normal. This is known as conductive hearing loss.
  2. Sensory-Neural Hearing Loss refers to damage to the inner ear or the auditory nerve which is the signal bearer to the brain. This type of condition occurs when there is physical harm to the end organ or the nerve. In most cases, sensory-neural hearing loss is irreversible. Using a hearing aid is only the solution as surgery itself is baseless in this case. Sensory-neural hearing loss is linked to blockage of blood supply or the sudden arrival of viral infection.

Safeguarding newborns from hearing loss is now recommended. In young ones, hearing impairment can lead to further problems such as slow growth, slow learning capabilities etc. By detecting problem in the initial stages, suitable measures can be taken to avert any of the aforementioned types of hearing loss.

How hearing loss is diagnosed?

The best available examination to determine an individual’s hearing abilities is an audiometry test. Before commencing the test, the ENT specialist may conduct a general screening test to know the extent of the condition. He/she may ask patient to cover up one ear at a time to see how well his/her ear responds when exposed to different sets of volume.

During a thorough test called audiometry, the patients are asked to wear headphones and hear sounds directed to one ear at a time. The ENT specialist presents an array of sounds of various tones and asks him/her to indicate each time. Each tone is repeated different times at different levels.

Special hearing tests including speech tests give a clear idea whether hearing loss is conductive or sensory-neural.

What are the treatment options for hearing loss?

The treatment for hearing loss varies according to the severity. Hearing aid is the only possibility if the damage is to the inner ear.

  1. Hearing Aids: The ENT doctor can discuss the probable advantages of using a hearing aid. Hearing aids cannot help every patient with hearing impairment, but they can enhance hearing for many people. However, getting adapted to it can take some time. Since, the sound coming through the hearing aid is amplified, it will take some adjustments before a patient gets used to it. Hearing aids should always be purchased after doing extensive research.
  2. Cochlear Implants: Cochlear Implants are considered when hearing aids fail to deliver. These implants are inserted into the inner ear but can cost you a fortune. They have their own set of complications. It is advisable to have healthy discussion with an ENT specialist before going for such implants.
