Frenzel maneuver

Frenzel maneuver is a technique often used by divers and aviators to equalize pressure in the middle ear. It is named after Hermann Frenzel, a German otolaryngologist who developed the maneuver during World War II to help Luftwaffe pilots avoid barotrauma.

History

The Frenzel maneuver was developed by Hermann Frenzel during World War II. Frenzel, a German otolaryngologist, was tasked with finding a solution to the common problem of barotrauma experienced by Luftwaffe pilots. The technique he developed is still widely used today by divers and aviators.

Technique

The Frenzel maneuver is performed by closing the mouth, pinching the nose, and making a swallowing or yawning motion. This action forces air up the Eustachian tubes, equalizing the pressure between the middle ear and the outside environment. The maneuver can be performed without the use of hands, making it particularly useful for divers and aviators who may need to equalize pressure while their hands are occupied.

Applications

While the Frenzel maneuver was originally developed for use by aviators, it is now commonly used by divers. The technique is particularly useful for scuba divers and free divers, who often need to equalize pressure in their ears as they descend and ascend. The Frenzel maneuver is also used in otolaryngology to treat patients with Eustachian tube dysfunction.
