What Experts Say"},"content":{"rendered":"

Hyperbaric chambers can cause ear pressure<\/a> and temporary discomfort, but permanent hearing loss from HBOT is not documented in large clinical studies. The most common ear issue is middle ear barotrauma<\/a>, a pressure equalization problem that affects roughly 9 to 15 percent of patients. Most cases are mild and self-resolving.<\/strong> This guide covers what the research shows, who is at higher risk, and how to protect your ears during HBOT.<\/p>\n

What Is Middle Ear Barotrauma?<\/h2>\n

Middle ear barotrauma (MEB) occurs when the air pressure outside your eardrum rises faster than the middle ear can equalize through the Eustachian tube. It is the same sensation you feel on an airplane during descent, amplified by the faster and larger pressure changes of a hyperbaric session<\/a>.<\/p>\n

During compression, if you cannot equalize the pressure difference, it creates pain, a feeling of fullness, and sometimes temporary muffled hearing. In mild cases the discomfort resolves once the chamber reaches operating pressure. In more severe cases, fluid may accumulate behind the eardrum, or the eardrum itself may be damaged.[2]<\/sup> Barotrauma and other ear and sinus effects are among the most frequently reported complications of HBOT overall.[5]<\/sup><\/p>\n

The condition is classified using the Teed Ear Drum (TEED) scale, from Grade 0 (no injury) to Grade 5 (tympanic membrane perforation). In Heyboer et al.’s study of 236 patients, 84 percent of MEB cases were Grade 1 to 2, meaning minor and requiring no medical intervention.[6]<\/sup><\/p>\n
