Ear Tubes
by Sharon L. Harp, MD
 
What are ear tubes?
     Ear tubes, also known as pressure equalizing (PE) or ventilating tubes, are small synthetic tubes placed through the eardrum.
 
What function do ear tubes perform?
     PE tubes provide a connection between the middle ear cavity and the external auditory canal via the eardrum.  This allows any fluid present in the middle ear to flow out into the canal, relieving the build-up of pressure and subsequent pain.  PE tubes also help to protect a child’s hearing that may be threatened if chronic fluid persists in the middle ear cavity.  PE tubes do not prevent ear infections.
 
Are tubes right for my child?
     If your child suffers from chronic fluid in the middle ear for a prolonged period of time (2-3 months) or has multiple ear infections (i.e. 4 infections in 4 months), your pediatrician may refer you to an otolaryngologist (ENT).  The ENT may recommend tube placement.  If indicated, PE tubes are placed under general anesthesia after which a small incision is made in the eardrum (also called a myringotomy).
 
After PE tube placement
    
Any build-up of fluid in the middle ear will drain through the tube.  Normal activities may resume, however earplugs are recommended for swimming, bathing, and other water activities.  Most ear tubes work their way out over a period of time between 6 and 8 months.
