What does the abbreviation PE tube stand for?

The abbreviation PE tube stands for Pressure Equalization tube. These tubes are commonly used in medical practice, particularly in otolaryngology, to treat conditions such as recurrent ear infections or fluid accumulation behind the eardrum. The purpose of a PE tube is to create a greater air pressure balance in the middle ear space, which helps to prevent the buildup of fluids that can lead to infections and hearing loss.

When placed, these tubes allow air to enter the middle ear, which promotes drainage and helps maintain equal pressure on both sides of the eardrum. This is crucial for the proper functioning of the eustachian tube, which helps to regulate pressure in the middle ear. Hence, the significance of the term "Pressure Equalization" directly relates to the tube’s function in managing ear pressure and preventing complications associated with middle ear disorders.
