Intratympanic Injections

Who will need intratympanic injections?

ENT specialists offer intratympanic injections as a part of treatment for Menier's disease, sudden hearing loss, autoimmune hearing loss or before a skull base inner ear surgery.

What does intratympanic injection mean?

In simple terms, it means that an ENT specialist is placing a medication in the middle ear with the help of a fine needle.

What happens on the day of the intratympanic injection procedure?

Before you leave for your appointment, have a painkiller medication. It would be best if you asked your family or a friend to drive you to the appointment. The doctor will go through the consent process and numb the ear canal with spray or cream when you arrive. Numbing medication is left in the ear canal for 30 to 45 minutes. Once the ear is numb, the cream and spray are cleaned, and a small needle is passed through the eardrum to inject medication in the middle ear space. The doctor will ask you to lie flat for 45min to one hour, allowing the medication to be absorbed into the inner ear.

What are the complications of intratympanic injections?

Ear pain is due to the buffer used in the steroid medication; it can sting when injected. It should only last for few minutes. It is advisable to have some painkillers before coming to your appointment.

Hearing loss: When the medication is injected into the middle ear, it can lead to muffled hearing for few days. Using gentamicin injections for Ménière's disease or skull base surgery can affect your hearing.

Hole in the eardrum: A hole in the drum made by a fine needle heals within few days. In a rare instance, it can lead to permanent perforation, which may need surgical repair.

Dizziness: Mild imbalance is usual after an injection. If you have injections before skull base surgery, this imbalance helps in post-op rehabilitation after a skull base surgery.

Ear infection and bleeding: these complications are exceedingly rare. While you have your treatment, you should avoid water getting into your ear by using a cotton ball with vaseline and an ear shower cap if you need to wash your hair.

How does an intra-tympanic steroid injection work?

The exact mechanism of action is not known. The medication injected into the middle ear helps in decreasing inner ear inflammation. There is strong evidence to suggest that intratympanic injections tend to work better in Meniere's patients in some cases.

Why did my Menière's disease not respond to intratympanic injections?

The patient has poorly defined Meniere's symptoms, associated vestibular migraine or bilateral Meniere's
The medication did not stay in the middle ear for a long time due to a wide eustachian tube and adhesions in it.

Boil in the Ear canal can be very painful...

How do I know I have boil in the ear canal? The ear canal is lined by skin up to the eardrum. Skin in the outer third of the ear canal has hair follicles. Hair follicles can get infected with bacteria and can form boil or furunculosis. It is challenging to look in our own ear canal. You can only feel a bump in the ear canal entrance which is tender to touch. Why is so painful when we have boil in the ear? Ear canal skin is very tightly attached to underlying cartilage. So any swelling in the skin stretches it and makes it very sore to touch. How do we get boil in the ear canal? Most common causes of boil in the canal is dryness of the skin and trauma. Dry skin leads to cracks and these cracks can get infected. People who use dry earbuds, fingers, towel edges or pens and traumatise ear canal skin, which can get infected with bacteria. How do I release the temptation of using earbuds? Some people can get very dry skin due to sensitivity to soup, shampoo or dy

Eustachian Tube Dysfunction

Are you unable to pop your ears or feeling pressure in your ears? Eustachian tube dysfunction is a very common problem after flu or cold or even after long haul flight when you feel hearing is muffled, feel pressure around the ears and sometimes you feel as if you are underwater. Good news is most of the time it is temporary. If you try decongestants, antihistamine ( hay fever tablets ) and Valsalva (ie try and pop your ears) things should improve after a few days to a week. Why do we have symptoms of Eustachian tube dysfunction? The eustachian tube is present at the back of our nose and connects the nose to the middle ear. It is there to maintain equal pressure on both sides of the eardrum. The eustachian tube also helps in clearing normal mucus from the middle ear. Hence opening and closing of this ventilation tube are very important for hearing. Normally every time we yawn and chew this tube opens and closes without us noticing it. So, if this opening of ventilation tube

Retracted Ear Drum

What Is a Retracted Eardrum? A retracted eardrum, also known as tympanic membrane retraction, is a condition where the eardrum (tympanic membrane) is pulled inward or drawn backwards from its normal position. The eardrum is a thin, delicate membrane that separates the outer ear from the middle ear. It plays a crucial role in transmitting sound vibrations from the outer ear to the middle ear, where the auditory ossicles (small bones) are located. Under normal circumstances, the eardrum is slightly concave and positioned at an angle that allows it to respond to changes in air pressure. The Eustachian tube, a tube connecting the middle ear to the back of the throat, helps equalize pressure between the middle ear and the outside environment. However, in cases of a retracted eardrum, the Eustachian tube might not function correctly or become blocked, leading to an imbalance in pressure. When negative pressure builds up in the middle ear, it causes the eardrum to retract inwa

Tonsil Stones or Tonsilloliths

Where do Tonsil Stones come from? Tonsil stones or tonsillolith are formed in the tiny crevices on the tonsil surface. Tonsils are present at the back of the throat. Two large tonsils on each side can catch food particles when we eat. This food debris can accumulate bacteria and give a bad smell. This mixture of bacteria and food debris can become solid to form tonsil stones. Can Tonsil Stones go away on their own? Tonsil stones form due to food particle and bacteria. You can prevent stone formation by regularly rinsing mouth after every meal, good oral hygiene and dental care. Gargling with salt water and gentle use of bud to deliver the stones can help in some cases. Soft water floss can help keep tonsil surface clean. If you have, post nasal drip due to sinusitis, seeking treatment advice from ENT surgeon can help. You should not use sharp objects to clean tonsil stones or make tonsil surface bleed. What symptoms do tonsil stones cause? Tonsil ston

LAX VOX

LAX VOX is a vocal therapy technique that can help improve voice quality, relaxation, and overall vocal health. It involves using a unique tube to create bubbling sounds while phonating. Here are the steps for practising LAX VOX: Relax and Focus on Posture and Breathing : Maintain a good posture with a long spine. Relax your face, neck, upper back, and chest muscles, allowing them to release toward gravity. Preparing for Bubbling with Phonation : Place a silicone tube (about 35 cm long and 9-12 mm in diameter) between or in front of your incisor teeth and above your tongue. Keep your tongue relaxed (imagine it as a piece of steak) and slightly touch the tube. Hold the water-filled bottle near your body to avoid using shoulder muscles. Inhale through your nose as if you’re yawning with your mouth closed. Prepare for phonation during exhalation, focusing on abdominal and lower back muscles. Finding the Target Voice : Create bubbling sounds with your voice: //hhhooooo// (both sh

Vertigo and Dizziness..

Are labyrinthitis and vertigo the same? The ear has three main parts: the outer ear, the middle ear, with small bones of hearing, and the inner ear, consisting of the labyrinth. The labyrinth has two parts as well, hearing processing part and balance part. When you get an infection in the inner ear, it is often called labyrinthitis. Common symptoms for Labyrinthitis are hearing loss or vertigo, however, there are also other causes for vertigo as well. What is the most important thing to remember when you have labyrinthitis symptoms? In the first few hours of symptoms, it is difficult to know between stroke and labyrinthitis. If you have vertigo and notice one side of your face becoming droopy, your arms or leg become weak and speech becomes slurred, you should call for urgent help. What is the difference between labyrinthitis and vestibular neuritis? If you only have vertigo symptoms, then it is due to vestibular neuritis. Vestibular neuritis oc

Cholesteatoma Ear Surgery

What is a Cholesteatoma? The ear has three parts outer ear (ear lobe and ear canal), the middle ear ( eardrum and bones of hearing) and inner ear. Cholesteatoma is skin from ear canal migrating into the middle ear. Like the skin on head keeps shedding and can cause dandruff. Similarly, skin in the middle ear can cause cholesteatoma, which can form a gradually expanding sac and can damage structures in the middle ear to give deafness, inner ear to give permanent deafness, nerve to the face to give a facial weakness or rarely give infection of the lining of the brain to cause meningitis Is cholesteatoma surgery or mastoidectomy done under general anaesthetic? Cholesteatoma is a surgical problem. Unfortunately, no medications work on it. Cholesteatoma surgery is called mastoidectomy, i.e. clearing cholesteatoma infection from the mastoid bone (the hard bone behind your ear). The procedure is done under general, i.e. you will be sleeping while the procedure is don
