True or False: Outer ear barotrauma can occur in the hyperbaric chamber.

1. True

2. False

3. It depends on the individual

4. Only in cases of extreme pressure

The correct answer is: False

Outer ear barotrauma can indeed occur in a hyperbaric chamber due to the pressure changes experienced when ascending or descending in a pressurized environment. However, it is typically associated with scenarios in which the equilibrium of pressure between the external ear canal and the middle ear is disrupted, such as during rapid altitude changes or underwater diving, rather than solely within a hyperbaric chamber setting. In a hyperbaric chamber, the gradual pressurization process usually allows adequate time for individuals to equalize the pressure in their ears, which minimizes the likelihood of developing barotrauma. Therefore, while it is theoretically possible to experience outer ear barotrauma in a hyperbaric chamber, it is considered extremely uncommon under normal conditions in a properly managed hyperbaric environment.
