Ear barotrauma is caused by sudden changes of pressure on the ear as a ride dips, rises and twists.
Previously, ear barotrauma has been linked to air travel, scuba diving and bomb blasts.
We conducted a prospective study to determine the incidence of middle ear barotrauma in patients who were undergoing hyperbaric oxygen therapy (HBOT).
(1) However, increasing the partial oxygen pressure in tissue and the atmospheric pressure during therapy may result in complications, the most common of which appears to be middle ear barotrauma. (2) Barotrauma can manifest as pain and pressure in the ear, serous otitis media, hemotympanum, and tympanic membrane perforations.
Otoscopic findings were categorized according to the modified Teed classification system of middle ear barotrauma (table).
Among the several complications of HBOT that have been reported so far, middle ear barotrauma is the most common.
Following a mean of 6 days ([+ or -]3) of treatment, middle ear barotrauma was seen in 34 of the 100 ears (34.0%).
