Many parents hear the words myringotomy and ventilation tubes for the first time when their child has had repeated ear infections, or when a teacher notices that the child is not hearing well in class. These terms sound complicated, but the procedure is one of the most common in paediatric ENT and its purpose is straightforward: to ventilate the middle ear and restore hearing.
In this article we explain when ventilation tubes are needed, how the procedure is carried out and what care is required afterwards.
What the middle ear is and why it fills with fluid
The middle ear is a small air-filled space located behind the eardrum (the tympanic membrane). This space is ventilated through a narrow channel that connects the ear to the back of the nose — the Eustachian tube.
In young children this tube is shorter, narrower and more horizontal than in adults, so it becomes blocked easily — particularly during colds, with allergies, or when the adenoids are enlarged. When the tube does not work properly, fluid collects in the middle ear. This condition is called serous otitis media, or otitis media with effusion: the ear does not necessarily hurt, but hearing is reduced as though the child had cotton wool in the ear.
When ventilation tubes are needed
The decision is always made individually by the ENT specialist, after examination and the relevant tests. In general, the procedure is considered in the following situations:
- Persistent fluid in the middle ear that does not clear after several months of observation and conservative treatment.
- Hearing loss confirmed by testing, which affects speech, learning or the child's behaviour.
- Repeated acute ear infections within a short period, with pain, fever and successive courses of antibiotics.
- Changes in the eardrum, such as retraction of the membrane, which can lead to more difficult problems if left untreated.
- Ongoing pain or discomfort in the ear caused by negative pressure.
The signs parents notice most often are: the child turns the television volume up high, asks you to repeat words, does not respond when called from another room, has difficulty concentrating, is late in speaking, or seems irritable and sleeps poorly.
Which examinations are carried out before the decision
Before any procedure is discussed, the specialist examines the ear with an otoscope or an endoscope, and performs tests that assess middle ear function and hearing levels — usually tympanometry (which measures the mobility of the eardrum) and audiometry, or age-appropriate hearing tests. The condition of the adenoids is often assessed as well, since enlargement is a frequent cause of blockage.
How myringotomy and tube insertion are performed
A myringotomy is a very small incision in the eardrum through which the fluid collected in the middle ear is suctioned out. So that the opening does not close immediately and the ear continues to be ventilated, a ventilation tube is placed — a tiny cylinder made of silicone or another biocompatible material, a few millimetres in diameter.
A few points that are useful to know as a parent:
- In children the procedure is usually performed under a short general anaesthetic, because the child must remain completely still.
- It is carried out through the ear canal, using a microscope or endoscope — there is no incision in the skin and no visible marks remain.
- It is short — generally a few minutes for each ear; most of the time is taken up by preparation and waking from the anaesthetic.
- In most cases it is a day procedure: the child goes home the same day, after a period of observation.
- If the adenoids are enlarged and considered the main cause, the doctor may propose removing them during the same session.
Many parents notice an improvement in hearing very soon after the procedure, because the fluid that was blocking sound has been removed. Some children are initially startled by louder sounds — this is normal and passes within a few days.
Care after the procedure
The first few days
It is common for a child to be a little drowsy or unsettled from the anaesthetic during the first day. There may be mild discomfort in the ear and, for a few days, a small amount of fluid or blood draining from the ear canal. If the discharge continues, has an unpleasant odour, or is accompanied by fever and pain, the doctor should be contacted.
Treatment after the procedure — including ear drops or pain relief — is determined solely by the doctor who performed it. Do not give any medication on your own initiative.
Water and bathing
Recommendations regarding water vary from case to case and according to the doctor's assessment. In general, daily washing is not a problem as long as soapy water does not enter the ear under pressure. For swimming, diving or baths in which the child puts their head under water, follow the specific instructions of your specialist — in some cases custom-made protective plugs are recommended.
Returning to normal activities
Most children return to nursery or school within one or two days, as soon as the effects of the anaesthetic have worn off and they feel well. Everyday activities, play and air travel are usually not restricted — in fact, the tube equalises pressure and makes flying more comfortable.
Follow-up appointments
After the procedure, periodic check-ups are needed to see whether the tube is in place, whether the ear is clear and how hearing is progressing. A repeat hearing assessment is usually carried out after a certain period.
How long the tubes stay in and what happens next
Ventilation tubes are not permanent. In most cases they come out on their own, pushed out by the natural growth of the eardrum tissue, and the opening closes by itself. This may happen after a few months or after more than a year, depending on the type of tube and on the child. Often parents do not even notice when the tube falls out.
In some children the problem returns and a second insertion may be needed. This does not mean that the first procedure
