Diver clearing ears Section of the human ear, the Eustachian tube is shown in colour. Ear clearing, clearing the ears or equalization is any of various maneuvers to equalize the pressure in the middle ear with the outside pressure, by letting air enter along the Eustachian tubes, as this does not always happen automatically when the pressure in the middle ear is lower than the outside pressure.
The maneuver is used to equalize pressure in the middle ear. Today, the maneuver is also performed by scuba divers, free divers and by passengers on aircraft as they descend. [1] [2] [3] The trapped air inside the mouth and nasal cavities is compressed by the movement of the tongue or larynx while doing Frenzel maneuver.
Middle ear barotrauma is the single most common diving disorder for which treatment is sought, at nearly 50% of all reported diving injuries. Many more milder cases may go unreported. A history of head and neck cancers, with associated radiation treatment, has been associated with a relatively higher incidence of MEBT, possibly due to radiation ...
The pressure in the middle ear not equalizing with external (ambient) pressure, usually due to failure to clear the Eustachian tube. [31] Ears can be equalized early and often during the descent, before the stretching is painful. The diver can check if the ears will clear on the surface as a precondition for diving. [31]

Variations of the maneuver can be used either in medical examination as a test of cardiac function and autonomic nervous control of the heart, or to clear the ears and sinuses (that is, to equalize pressure between them) when ambient pressure changes, as in scuba diving, hyperbaric oxygen therapy, or air travel.
