Tympanostomy

Tube Placement in the Ear

Why are children at risk for chronic ear infections?

Young children experience more ear infections than adults because the main ventillation tube for the air pocket under the eardrum (the eustachian tube) is immature, and predisposes to developing ear infections instead of preventing them.  The eustachian tube connects the ear to the back of the nose, and is what “pops” when you yawn, sneeze, fly, etc.

Ear infections also create thick fluid under the eardrum as well, and this is what muffles hearing and sets the stage for further infections.  Antibiotics may clear the infection, but may not be enough to resolve the fluid trapped under the eardrum.  This is why some children have chronic ear infections despite numerous antibiotics.

What are tympanostomy tubes and how do they work?

Ear tubes (i.e. tympanostomy tubes or myringotomy tubes) are small pieces of plastic or metal that is placed through the eardrum to ventilate the space underneath.  They prevent fluid from building up under the eardrum and provide better long term control of ear infections than antibiotics alone.

Tubes are placed for frequent and persistent ear infections that do not respond to antibiotics.  The risk of ear infections drops significantly after tympanostomy tubes are placed.  Persistent fluid in the ear that muffles hearing or causes speech delay in children is also effectively treated with tympanostomy tubes.

Tympanostomy tubes last 1-2 years, and then fall out on their own.  The chances of falling “in” under the eardrum are very low. Scarring of the eardrum is usually minimal and does not affect hearing. The chances of needing a second set of tympanostomy tubes are less than 20%.  Children typically do not feel the tubes while they are in place and cannot reach them.

Ear drainage with tubes is uncommon, and its appearance usually means an ear infection is present. Pain, fever, and irritability are usually not seen with ear infections with tympanostomy tubes.  Antibiotic ear drops are often all that is required to control ear drainage.

How involved is having tympanostomy tubes placed?

Placing tympanostomy tubes is done in the operating room and takes about 5 minutes of anesthesia (usually with only a mask).  Most children are ready to go home 15 minutes after the procedure is complete, and are normal by the end of the day.  While activity is not restricted after tympanostomy tube placement, ear plugs are recommended with exposure to untreated water (lake, river, ocean, etc).
