Which of these techniques is commonly used to equalize eustachian tube pressure?

  1. Frenzel maneuver

  2. Chewing gum

  3. Neck stretching

  4. Yawning

The correct answer is: Frenzel maneuver

The Frenzel maneuver is a specialized technique utilized to equalize pressure in the eustachian tubes, which connect the middle ear to the nasopharynx. This maneuver involves closing the mouth, pinching the nose shut, and using the back of the tongue to push air toward the eustachian tubes. By creating a pressure gradient, air is drawn into the tubes, helping to equalize the pressure in the middle ear with the ambient pressure. This method is particularly effective in situations where pressure changes occur, such as during descent in scuba diving. While chewing gum, neck stretching, and yawning may also help with pressure equalization, they are not as specifically effective as the Frenzel maneuver. Chewing gum can stimulate saliva production and promote swallowing, which may help open the eustachian tubes, but it does not actively control the pressure like the Frenzel maneuver. Neck stretching and yawning can also aid in opening the eustachian tubes, but they do not provide the same level of control over pressure changes as the Frenzel maneuver does. Thus, the Frenzel maneuver stands out as a direct and efficient technique to equalize eustachian tube pressure.
