Ear tubes (tympanostomy tubes, ventilation tubes, pressure equalization tubes) are tiny cylinders, usually made of plastic or metal, that are surgically inserted into the eardrum. An ear tube creates an airway that ventilates the middle ear and prevents the accumulation of fluids behind the eardrum.
Ear tubes are often recommended for children who have persistent fluid buildup behind the eardrum, especially if the condition causes hearing loss and affects speech development. Your child's doctor may also recommend ear tubes if your child gets frequent ear infections.
Most ear tubes fall out within six to 12 months, and the holes heal shut on their own. Some tubes need to be removed, and some holes may need to be closed surgically.
The cost of Ear tube surgery with Ear Tube Insertion start from $180.
An ear tube is used most often to provide long-term drainage and ventilation to middle ears that have had persistent fluid buildup, chronic middle ear infections or frequent infections.
Normal ear ventilation
Ventilation of the middle ear is normally accomplished by the eustachian tubes, a pair of narrow tubes that run from each middle ear to high in the back of the throat. The throat end of the tubes opens and closes to:
Regulate air pressure in the middle ear
Refresh air in the ear
Drain normal secretions from the middle ear
Swelling, inflammation and mucus in the eustachian tubes from an upper respiratory infection or allergy can block them, causing the accumulation of fluids in the middle ear. This problem is more common in children, in part, because their eustachian tubes are narrower and more horizontal — factors that make them more difficult to drain and more likely to get clogged.
Ventilation with ear tubes
Ear tubes provide an alternative airway to keep the air in the middle ear refreshed, allow for normal drainage and equalize the pressure in the ear. The tubes are most often used in children with one of the following conditions:
Fluid trapped behind the eardrum is inflammation and fluid buildup (effusion) in the middle ear without bacterial or viral infection. This may occur because the fluid buildup persists even after an ear infection has resolved. It may also occur because of some dysfunction or noninfectious blockage of the eustachian tubes.
Hearing loss often results from otitis media with effusion. Hearing loss can lead to delays in speech development, communication problems, behavior problems and poor school performance.
Middle ear infections are generally considered frequent if there are three or more distinct episodes in six months or four or more episodes in a year. Ear tubes may help prevent recurring infections.
Chronic middle ear infections are long-term infections of the middle ear that don't improve with antibiotic treatment.
Chronic suppurative otitis media is a persistent ear infection that results in tearing or perforation of the eardrum.
Ear tube surgery in iran is a relatively safe procedure with a low risk of serious complications. Possible risks include:
Bleeding and infection
Persistent drainage of fluid
Blocked tubes from blood, mucus or other secretions
Scarring or weakening of the eardrum
Tubes falling out too early or staying in too long
Failure of eardrum to close after the tube falls out or is removed
Surgery for ear tube placement usually requires general anesthesia, which carries some risks as well. Although the risks of anesthesia are very low in otherwise healthy children, possible problems include:
Nausea or vomiting after the procedure
You'll receive instructions from the hospital on how to prepare your child for surgery to place ear tubes.
Information to provide may include:
All medications your child takes regularly
Your child's history or family history of adverse reactions to anesthetics
Known allergy or other negative reactions to medications, such as antibiotics
Questions to ask your doctor or the hospital staff:
When does my child need to start fasting?
What drugs can he or she take before surgery?
When should we arrive at the hospital?
Where do we need to check in?
What is the expected recovery time?
How will the anesthetic be administered — with a face mask, injection or intravenous (IV) line?
Tips for helping your child prepare include:
Start talking about the hospital visit a few days before the procedure.
Explain that the procedure will help make his or her ears feel better or make it easier to hear.
Explain that a special medicine will help him or her sleep during the surgery.
Let your child pick out a favorite comfort toy, such as a blanket or stuffed animal, that you can take to the hospital.
Explain that you will be there during the procedure.
A surgeon specializing in ear, nose and throat disorders performs the surgery for placing ear tubes.
The surgeon usually performs the procedure during general anesthesia, so your child isn't aware of anything during the procedure. The anesthetic medication may be inhaled through a mask, injected into a vein or both.
The surgical team places several monitors on your child's body to help make sure that his or her heart rate, blood pressure and blood oxygen remain at safe levels throughout the procedure. These monitors include a blood pressure cuff on the child's arm and heart-monitor leads attached to your child's chest.
During ear tube surgery
The procedure usually takes about 15 minutes. The surgeon:
Makes a tiny incision in the eardrum (myringotomy) with a small scalpel or laser
Suctions out fluids from the middle ear
Inserts the tube in the hole in the eardrum
After surgery, your child is moved to a recovery room where the health care team watches for complications from the surgery and anesthesia. If there aren't any complications, your child will be able to go home within a few hours.
Your child will likely be sleepy and irritable for the rest of the day and possibly nauseated from the anesthetic. In most cases, children resume regular activities within 24 hours of the surgery.
Your child's doctor will advise you about follow-up care after ear tube placement.
Standard follow-up care
If your child has no complications:
An initial follow-up appointment will be scheduled within the first two to four weeks after the procedure. At that time, your child's ear, nose and throat specialist will check for appropriate placement and function of the tubes. Other follow-up appointments with the otolaryngologist or your child's primary care physician will be scheduled at four- to six-month intervals.
Your child's ear, nose and throat specialist may prescribe eardrops to help minimize fluid discharge from the ear. Use the full course as directed by your doctor even if no drainage problems appear.
If the child had hearing loss before the procedure, the doctor will also order a hearing test (audiogram) to assess hearing outcomes after.
Your child's doctor may suggest that your child wear earplugs during swimming or bathing.
When to contact your doctor
Reasons to see your child's ear, nose and throat specialist outside of regularly scheduled follow-up appointments include:
Yellow, brown or bloody discharge from the ear (otorrhea) that continues for more than a week.
Persistent pain, hearing problems or balance problems.
