Ep. 32: Avoid Long-term Damage from these Glue Ear Complications
Show Notes
Today’s episode discusses the glue ear complications that can lead to permanent hearing loss. I have previously defined glue ear so that we can all be on the same page, and I also have discussed treatment and prevention options for glue ear. However, at this point, we need to understand why it is important to treat.
Although glue ear is simply fluid trapped behind the eardrum, there is nothing simple about its potential complications. The summary below outlines my discussion but be sure to check out the audio where I delve deeper into explanations and descriptions.
What are the most common glue ear complications?
Glue ear is very different from acute ear infections; therefore, the complications from recurrent ear infections are also very different.
Although middle ear fluid is not as severe as ear infections, when it is present for a long time, it becomes a serious problem. The classic glue ear complications include
- Recurrent ear infections
- An acute ear infection (otitis media) is a common complication of glue ear, and it develops when bacteria infect the fluid inside the middle ear.
- Hearing loss
- When there is fluid instead of air, it is harder for the eardrum to vibrate and carry the noise vibrations to the inner ear.
- I have already shared the different types of hearing loss. Glue ear usually leads to the conductive hearing loss type.
Glue ear occurs most often in young children during a critical time of their learning and development. Some common negative effects of long term glue ear in kids include
- Balance problems
- Speech delay
- Language delay
- Reading and comprehension delay
- Learning difficulties
- Difficulty with social interactions
- Attention and focus concerns, especially in school
What are some less commonly known impacts of long term glue ear?
Most people are aware of the importance of having normal hearing for our everyday lives. However, in kids, during their critical developmental years, hearing loss may lead to problems that are not as well known. This group of kids is often under-identified and under-treated.
Sensory Processing Disorder
- Sensory processing disorder is a condition in which the brain has trouble receiving and responding to information that comes in through the senses.
- This could affect one sense, like hearing, touch, or taste. Or it may affect multiple senses. And people can be over- or under-responsive to the things they have difficulties with.
- Although many kids have these symptoms, there is a big debate about whether this represents a true medical disorder.
Auditory Processing Disorder
- Auditory processing disorder (APD), also known as central auditory processing disorder (CAPD), is a hearing problem that affects about 5% of school-aged children
- This problem causes kids to be unable to process what they hear in the same way other kids do because their ears and brain don’t fully coordinate.
5 ways glue ear leads to permanent eardrum and hearing damage
When middle ear fluid remains present for a long time, there are chronic changes to the tissues in the middle ear. The fluid makes the surrounding tissues begin to swell which initially is reversible, consequently, over time, the swelling leads to chronic scarring and damage that requires extensive surgery to repair it and restore hearing.
Tympanosclerosis
- Describes thickening of the eardrum with scar tissue and calcifications (looks like white chalky patches on the eardrum)
- Often associated with ear tube placement because it can occur in 25% of cases; however, it occurs in a large number of people where it is not a complication of ear tubes.
- Usually, when limited only to the surface of the eardrum, there is only a small amount of hearing loss associated with this problem.
- If severe, a large part of the eardrum becomes scarred and hearing loss may be significant.
- The scar tissue and calcification can also occur inside the middle ear and around the hearing bones
Eardrum Perforation
- The classic eardrum perforation occurs with an acute ear infection, where trapped pus bursts through the eardrum. This is not the perforation I am talking about.
- Also not talking about the perforation that occurs with trauma (which is a common reason for recommending NOT to use Qtips to clean ear wax)
- When untreated glue ear persists, the progressively thicker fluid takes up less space in the middle ear, and the eardrum is pulled inward. This stage is called eardrum retraction.
- The constant pull of the eardrum may cause it to thin out and makes it more susceptible to a perforation that does not heal.
Atelectasis
- This is a more extensive or severe form of eardrum retraction.
- As glue ear continues to be present, more advanced retraction occurs and varying amounts of the eardrum are pulled into the middle ear.
- There are dangers from the eardrum being pulled into the middle ear, including a complication called cholesteatoma.
- Sometimes, such a large amount of eardrum is pulled inward that it looks like an eardrum perforation.
- Check out this video which shows how the eardrum may look like it is perforated but instead, it has atelectasis.
Adhesive Otitis
- When retraction or atelectasis occur for a long time, the eardrum begins to irritate the lining of the middle ear, and scar bands form to attach the tissues together.
- At this stage, the eardrum no longer has the ability to move to its normal position, even if the eustachian functioning is improved or if an ear tube is inserted. An ear tube cannot reverse this chronic change to the eardrum.
- Severe cases require the eardrum to be reconstructed.
Fibro-adhesive Otitis
- This is one of the end-stage complications of glue ear
- The inflammation between the eardrum and middle ear structures become completely filled with scar tissue and the middle ear essentially becomes lined by the retracted eardrum
- Surgical repair is extremely difficult
Summary of the stages of glue ear complications
Over a long period of time, all the air in the middle ear gets absorbed and creates a negative pressure. (eustachian tube dysfunction)
- The negative pressure allows fluid to build up in the middle ear. (otitis media with effusion)
- The fluid becomes very thick and darker in color. (glue ear)
- The negative pressure in the middle ear pulls the eardrum inward. (retraction)
- The eardrum thins out and loses some of its strength. (atelectasis)
- Over time the drum becomes adherent to the middle ear structures. (adhesive otitis)
- The fluid may eventually resolve and become replaced with scar tissue but the negative pressure in the middle ear continues. (fibroadhesive otitis)
- As the negative pressure in the middle continues to pull the eardrum inward, skin cells may become trapped which leads to the formation of a cholesteatoma.
