Ear Tubes

Ear tube insertion (myringotomy) is the placement of tubes through the tympanic membrane or eardrum. It is done to allow the fluid behind the patient's eardrums to drain so that the ears can function normally.

Description

While the patient is under general anesthesia (asleep and not able to feel pain), a small surgical cut is made in the eardrum. The built-up fluid is suctioned out through this cut. Then, a small tube is inserted through the eardrum. The tube allows air to flow in and fluid to constantly flow out of the middle ear.

Why the Procedure is Performed

Ear tube insertion may be recommended when fluid builds up behind the eardrum and does not go away after 4 months or longer. Fluid buildup may cause some hearing loss while it is present. But most patients do not have long-term damage to their hearing or their ability to speak even when the fluid remains for many months.

An ear infection is another reason for inserting an ear tube. If an infection does not go away with the usual medical treatment, or if a patient has many ear infections over a short period of time, the doctor may recommend ear tubes.

Ear tube insertion is also used sometimes for people of any age who have:

  • Barotrauma (pressure injury) from flying or deep sea diving
  • Hyperbaric oxygen therapy
  • A complication from a severe ear infection, such as mastoiditis, brain infection, meningitis, or facial nerve paralysis

Risks

The risks for any anesthesia are:

  • Breathing problems
  • Reactions to medicines
  • The risks for any surgery are:
  • Bleeding
  • Infection

Risks of this surgery are scarring of the eardrum and drainage from the ear. These complications do not usually last long. They also do not usually cause problems in patients. Your doctor can explain these complications in more detail. There is also a very small risk of a hole remaining in the eardrum after the tube comes out.

Before the Procedure

Your ear specialist may ask for a complete medical history and physical exam of your child before the procedure is done.

Always tell your doctor or nurse:

  • What drugs you are taking. Include drugs, herbs, and vitamins you bought without a prescription
  • What allergies you may have to any medicines, latex, tape, or skin cleaner

On the day of the surgery:

  • You will usually be asked not to drink or eat anything after midnight the night before the surgery.
  • Take a small sip of water with any drugs your doctor told you to give you to take. 
  • Your doctor or nurse will tell you when to arrive at the hospital.
  • The doctor will make sure you are healthy enough for surgery. This means your child has no signs of illness or infection. If you are ill, the surgery may be delayed.

After the Procedure

Patients usually stay in the recovery room for a short time and leave the hospital the same day the ear tubes are inserted. You may be groggy and irritable for an hour or so as you awaken from anesthesia. Your doctor may prescribe ear drops or antibiotics for a few days after the surgery.

Most patients can return to normal activities the day after the surgery.

Some ear specialists will recommend earplugs or swimmer’s headbands while swimming or bathing to keep water out of the ears. If earplugs are not recommended for these activities, they may be recommended for diving in deep water. Check with your ear specialist.

The surgical cut heals on its own, without stitches. The hole closes, and the ear tubes usually fall out on their own after 14 months or so.

Outlook (Prognosis)

After this procedure, most patients report they have fewer ear infections, recover fast from infections, and that they worry less about ear infections.

If the tubes do not fall out on their own, an ear specialist may have to remove them. If ear infections return after the tubes fall out, another set of ear tubes can be inserted.
