Myringotomy with Tympanostomy Tubes

About Myringotomy with Tympanostomy Tubes

Myringotomy with insertion of tympanostomy tubes, also called grommets or ear tubes, is one of the most common operations performed on children. A tiny incision is made in the eardrum under a microscope, fluid is suctioned from the middle ear and a small tube is placed in the opening. The tube ventilates the middle ear space, equalizing pressure and allowing fluid to drain. The main indications are persistent fluid behind the eardrum with hearing loss, known as otitis media with effusion, and recurrent acute ear infections. Tubes are also used in some adults with eustachian tube problems. In children the procedure is usually done under brief general anesthesia, while in adults it may be performed in the clinic with local anesthesia. Most tubes are designed to fall out on their own as the eardrum heals, typically within months to a couple of years, while long term tubes stay in longer. Clinical practice guidelines from professional societies define which children are most likely to benefit.
