This is the best place to learn how to equalize ear canals. Toynbee is a safe way to equalize ears. It doesn't use the Valsalva maneuver as it is most commonly used. Instead, the technique involves gently sucking in/out of the mouth. You'll notice a difference in your hearing after swallowing.
Eustachian tubes equalize when you swallow
The eustachian tubes are a series of passageways that connect the middle ear with the nasopharynx, or back of the nasal cavity. They work by equalizing the air pressure between the middle and back of the nasal cavity. Swallowing and chewing allow air to flow through the tubes. If the tubes become blocked, the middle of the ear can't function properly and this can cause hearing loss.
A clogged eustachian tube can cause pain and discomfort in the ears, and in some cases, may even result in ear damage. This condition is often temporary and can usually be treated by treating the underlying cause (e.g. sinus infection or nasal congestion). There are two options for treatment: decongestants and antibiotics. Some cases may require surgery in order to restore normal eustachian function.
Valsalva maneuver doesn't equalize ears
There are several methods that can equalize your ears. One is the Valsalva maneuver. This maneuver involves pinching your nostrils, blowing through your nose and creating excessive throat pressure. This pushes air through the Eustachian tubes, opening them. The Valsalva maneuver can be useful, even though it's not as effective as breathing through the mouth.
Another way to equalize the airflow is to squeeze the nostrils, and then blow the air into your sinuses. This is the easiest way to equalize your ears. Although this works well, avoid blowing too hard on your nose. It can cause more damage to your ears. Blowing your nose too hard can damage your ears' tissue and cause your round windows to burst.
Toynbee maneuver equalizes ear safely
Toynbee equalizes pressure in the middle. The middle ear is a dead space and must be equalized to match the inner and outer ear pressures. To do this, one should swallow and then gently pinch their nose. This can reduce pain due to middle ear pressure imbalance.
It's important to practice this maneuver in order to avoid locking the Eustachian tubes. These tissues can be damaged if too much pressure is applied. You should learn the Toynbee maneuver well.
Signs of an improper equalization
Proper equalization techniques are essential for free divers. Incorrect equalization techniques can result in inner ear barotrauma. Specifically, forceful Valsalva maneuvers can cause the round window to rupture. This happens when the fluid pressure rises and the round window bursts. This condition can be very dangerous and requires immediate medical attention.
If you feel pain during equalization, stop immediately. Equalization should not be extended beyond what is necessary to prevent the Eustachian tubs from locking up. Instead, try ascending a few feet. If equalization still feels painful, lower your head and try again. The Lowry technique, which combines both the Valsalva maneuver and the Toynbee maneuver, is recommended if pain persists. To equalize your ears, you can pinch your nose and swallow.
