The pressure difference between the middle ear and the outside, if not released, can result in a burst eardrum. [10] This damages hearing, [11] and if this occurs underwater, cold water in the middle ear chills the inner ear, causing vertigo. [12] The pressure difference can also cause damage to other body air spaces, such as the paranasal ...
It is far more targeted, effective, and ultimately safer (the increased pressure exerted by the Valsalva technique can actually harm your ears).This procedure is easier to do and does not require as much oxygen as the valsalva maneuver. It is effective in depths of up to -80 meters and can be performed multiple times quickly underwater.
The Valsalva maneuver can also help to temporarily unblock or equalize the pressure in the middle ear. To do this, simply pinch your nostrils closed with one hand and blow air through your nose.
There are several ways to unclog your ears safely, depending on what is causing your discomfort. Here, experts explain options for relief.
Opening pressure has been proposed as a method for preoperative and intraoperative evaluation of any obstructive process within the Eustachian tube. [3] As well, Valsalva CT scanning using advanced 64 slice or higher machines has been proposed as a way of diagnosing and localizing anatomic obstruction within the Eustachian tube.

Middle ear barotrauma (MEBT), also known to underwater divers as ear squeeze and reverse ear squeeze, is an injury caused by a difference in pressure between the external ear canal and the middle ear. It is common in underwater divers and usually occurs when the diver does not equalise sufficiently during descent or, less commonly, on ascent.
Other symptoms include the feeling of pressure in the brain, mostly around the frontal lobe area, headaches or migraine headaches, ear pain, ear fullness and possibly tinnitus. [citation needed] Fluctuations in weather also affect sufferers, in particularly hot weather and barometric pressure changes.
