What is the most common type of barotrauma experienced by divers?

Middle ear squeeze is the most common type of barotrauma experienced by divers due to the physiological changes that occur during descent and ascent in water. When a diver descends, the pressure increases on the outside of the ear, while the air space inside the middle ear remains at a lower pressure. If the diver cannot equalize the pressure in the middle ear through techniques such as swallowing, yawning, or using the Valsalva maneuver, this pressure difference can result in discomfort, pain, and potential injury to the ear structures.

This condition specifically highlights the importance of pressure equalization for maintaining ear health during diving activities. As divers go deeper, the risks of middle ear squeeze increase, making it essential for them to understand the mechanics of equalization and how to prevent this type of barotrauma.
