Tympanostomy tube

A Tympanostomy tube (pronounced: tim-pan-OS-toe-me tube), also known as a grommet, ear tube, or pressure equalization (PE) tube, is a small tube inserted into the eardrum to allow air to enter the middle ear.

Etymology

The term "tympanostomy" is derived from the Greek words "tympanon" (drum) and "stoma" (mouth or opening). The term "grommet" is of unknown origin, but it is used in British English to refer to a small tube inserted into a hole to protect or insulate something.

Usage

Tympanostomy tubes are often used in children who have chronic otitis media (middle ear infections) or otitis media with effusion (fluid in the middle ear). The tubes help to equalize the pressure between the middle ear and the atmosphere, which can help to alleviate symptoms such as hearing loss, pain, and speech delay.

Procedure

The procedure to insert a tympanostomy tube, known as a myringotomy, is usually performed under general anesthesia in children and local anesthesia in adults. A small incision is made in the eardrum, any fluid is suctioned out, and the tube is inserted. The procedure usually takes about 15 minutes.

Risks and Complications

As with any surgical procedure, there are risks associated with tympanostomy tubes. These can include infection, bleeding, and damage to the eardrum or nearby structures. In some cases, the tubes may fall out too soon or stay in too long, requiring additional procedures.
