Myringotomy: Draining Fluid From the Middle Ear

When fluid keeps building up behind the eardrum — a common problem in young children — myringotomy offers a quick, minor procedure to drain it and often place a tiny ventilation tube to keep the ear clear going forward.

What Is Myringotomy?

Myringotomy is a minor surgical procedure in which a small incision is made in the eardrum to drain fluid that has built up in the middle ear. It's frequently combined with the insertion of a tiny ventilation tube (also called a grommet or tympanostomy tube) through the same opening, which keeps the middle ear aerated and prevents fluid from re-accumulating. It's one of the most common surgical procedures performed in young children.

Why Does Fluid Build Up in the Middle Ear?

• Otitis media with effusion ("glue ear") — fluid that lingers in the middle ear after an infection clears, or without ever having an obvious infection
• Recurrent acute ear infections that keep filling the middle ear space with fluid or pus
• Eustachian tube dysfunction — in young children especially, the tube connecting the middle ear to the back of the nose is shorter and more horizontal, making drainage less efficient
• Enlarged adenoids blocking the eustachian tube opening
• Allergies or colds that cause swelling around the eustachian tube

Fluid can build up in the middle ear space behind the eardrum

Signs and Symptoms

• Hearing loss or a feeling of fullness in the ear
• In children: delayed speech development, inattentiveness, or turning up the TV volume
• Recurrent ear infections
• Ear pain, particularly with active infection
• Balance issues or clumsiness in some children
• A feeling of popping or crackling in the ear

When Is the Procedure Recommended?

Myringotomy (often with tube placement) is typically considered when fluid has persisted in the middle ear for three months or more, when a child has had multiple, frequent ear infections despite treatment, or when the fluid is affecting hearing enough to impact speech or language development.

How the Procedure Works

1. Anesthesia. In children, this is almost always done under brief general anesthesia since it requires the ear to stay perfectly still; adults may have it done under local anesthesia in the office.
2. Making the incision. Using a microscope for magnification, the surgeon makes a very small, precise incision in the eardrum.
3. Draining the fluid. The trapped fluid behind the eardrum is suctioned out through the opening.
4. Placing a ventilation tube. A tiny tube is often inserted into the incision to keep it open, allowing the middle ear to stay ventilated and drained for months at a time rather than the incision healing over right away.

The entire procedure typically takes only 10–15 minutes.

Recovery

• Same day: Most children go home within an hour or two, often with noticeably improved hearing right away.
• Ear drops: Antibiotic ear drops may be prescribed for a few days after surgery.
• Water precautions: Ear plugs are often recommended during bathing and swimming while a tube is in place, following your surgeon's specific guidance.
• Tube lifespan: Ventilation tubes typically fall out on their own after six months to a couple of years as the eardrum grows and heals.

The eustachian tube, which normally drains the middle ear, connects to the back of the nose

Risks and Considerations

• Temporary drainage or minor bleeding from the ear
• Infection around the tube
• Tube blockage or premature falling out
• A small, usually harmless residual hole in the eardrum after the tube falls out (uncommon)
• Need for a repeat procedure if fluid recurs after the tube falls out

The Takeaway

Myringotomy, especially with ventilation tube placement, is a quick, low-risk procedure that resolves one of the most common causes of hearing trouble and recurrent ear infections in young children. If your child has had persistent fluid in the ear, frequent infections, or signs of hearing difficulty, an ENT evaluation can determine whether this simple fix is the right option.
