How Do Ear Drains Work?

Published in Ear Drainage 2 mins read

Ear drains, also known as ear tubes, tympanostomy tubes, ventilation tubes, myringotomy tubes, or pressure equalization tubes, are small, hollow tubes surgically inserted into the eardrum. Their primary function is to allow air to enter the middle ear. This air flow serves two crucial purposes:

Equalizing Pressure and Draining Fluid

  1. Pressure Equalization: The tubes equalize the air pressure between the middle ear and the outside environment. This prevents the build-up of pressure that can cause pain and discomfort, especially during altitude changes (like in an airplane) or with changes in atmospheric pressure. [Cleveland Clinic]

  2. Fluid Drainage: By allowing air to flow freely, the tubes facilitate the drainage of any excess fluid that may accumulate behind the eardrum. This fluid buildup is a common occurrence during ear infections and can lead to hearing impairment. [Mayo Clinic] The drainage often appears as a yellowish or whitish discharge from the ear.

The Procedure

A surgeon creates a tiny hole in the eardrum (myringotomy) and inserts the tube. The tube remains in place for a period, usually several months to a year, after which it typically falls out on its own. During this time, the tube actively allows for air circulation and fluid drainage. [UVA Health, Children's Minnesota]

Post-Procedure Care

Following the procedure, some fluid drainage from the ear may be expected for about a week. [WebMD] It's crucial to avoid inserting anything into the ear canal and to follow the surgeon's instructions regarding ear care. [UVA Health] Swimming may be allowed depending on the absence of any drainage from the ear. [Seattle Children's] If an ear infection develops and discharge is evident, this is an indicator that the tubes are still functional and draining infection. [Total ENT Care]

While home remedies like warm compresses might provide some temporary relief, they cannot replace the function of surgically placed ear drains. [Verywell Health]
