What is the Toynbee Maneuver?

Published in Diving Physiology 3 mins read

The Toynbee maneuver is a technique used to equalize pressure in the middle ear, particularly useful during descent in scuba diving or air travel. It involves pinching your nose and swallowing simultaneously.

How the Toynbee Maneuver Works

The Toynbee maneuver relies on the body's natural mechanisms to equalize pressure. Here's a breakdown:

  1. Pinching the Nose: This blocks the nostrils, creating a closed system in the nasal cavity.
  2. Swallowing: This action does two key things:
    • Opens the Eustachian tubes, which connect the middle ear to the back of the throat.
    • Moves the tongue, compressing air against the closed nasal cavity.

The combination of these actions forces air through the Eustachian tubes and into the middle ear, thereby equalizing the pressure with the surrounding environment. This is crucial to prevent barotrauma, or ear squeeze, which can occur when pressure differences cause pain and damage to the eardrum.

When to Use the Toynbee Maneuver

The Toynbee maneuver is most effective during descent (in diving or flying) as the external pressure increases. Performing this maneuver frequently during descent can help prevent pressure imbalances before they become problematic. It is also helpful when a diver or flyer is having trouble equalizing using other methods.

Differences from the Valsalva Maneuver

While both the Toynbee and Valsalva maneuvers are used for ear equalization, they work differently. The Valsalva maneuver involves pinching the nose and blowing gently. This forces air into the Eustachian tubes. The Toynbee maneuver uses swallowing to achieve the same result. Some people find one method more effective than the other. In fact, some experts recommend that performing both the Valsalva and Toynbee maneuvers concurrently may be effective in cases where performing either method alone has not provided relief.

Considerations and Tips

  • Start Early: Begin equalizing pressure before you feel any discomfort.
  • Stay Relaxed: Tension can make equalization more difficult.
  • Descend Slowly: Give your ears time to adjust to the pressure changes.
  • If You Can't Equalize, Ascend Slightly: This can relieve pressure and allow you to try equalizing again.
  • Consult a Doctor: If you frequently have trouble equalizing your ears, consult with an ear, nose, and throat (ENT) specialist.
