![]() Middle ear squeeze occurs when you cannot equalize the pressure in your middle ear.This can damage the tissue in the ear canal, usually your eardrum. ![]() As the water pressure increases while you descend, the air pocket between the obstruction and the tympanic membrane (eardrum) shrinks. External ear squeeze occurs when your ear canal is blocked by something such as earplugs or earwax.However, if a diver ascends too quickly, nitrogen gas bubbles will form in body tissue rather than being exhaled. Because of the water pressure, body tissue absorbs nitrogen gas faster as a diver descends than when ascending to the surface. Decompression sickness, or "the bends," is related more to Henry's Law, which states that more gas will be dissolved in a liquid when the gas is pressurized.As you dive deeper when scuba diving, pressure increases, and this volume change in gas-filled spaces and organs within your body accounts for the distortion and damage to surrounding tissues. As the pressure increases, the volume decreases and vice versa. Boyle's law states that the product of the multiplication of pressure and volume remains a constant. (2017, June 13).What Facts Should I Know about Barotrauma/Decompression Sickness?īarotrauma refers to medical problems that arise from the pressure differences between areas of the body and the environment and is a particular concern for scuba divers.Ĭertain laws of physics apply to this topic.

Medical News Today has strict sourcing guidelines and draws only from peer-reviewed studies, academic research institutions, and medical journals and associations. However, surgeons rarely use this procedure to treat ear barotrauma. The use of ear tube placement surgery is common in children who have hearing loss due to recurrent infections or ongoing fluid collection in the middle ear. Using a particular surgical procedure, it is possible to implant small cylinders called ear tubes into the ear. In cases of chronic or severe ear barotrauma, a doctor may decide that surgery is necessary. If an infection is present, a doctor may prescribe antibiotic therapy. It is essential to keep the ear clean and away from contamination to prevent any infection while it is healing. People should avoid putting drops in the ear. Stopping a diving descent at the first sign of ear discomfort to allow time for equalizing.If a person has upper respiratory congestion or an allergy, this may help the eustachian tube to stay open. Taking an over-the-counter (OTC) nasal decongestant, antihistamine, or both.Using the mouth helps to open up the eustachian tube. Chewing gum, sucking on a lozenge, swallowing, or yawning.This allows air to enter or leave the middle ear to equalize the pressure. However, it should be possible to relieve the symptoms of mild ear barotrauma by using certain techniques to help open the eustachian tube. Most cases of ear barotrauma will resolve after a short period without the need for medical intervention. Share on Pinterest Chewing gum may help to relieve the symptoms of ear barotrauma. People with these symptoms may need to seek treatment to get symptom relief. pressure sensation in the ear, similar to how it feels being underwater.In moderate to severe cases, or if ear barotrauma persists without treatment, a person may experience additional or worsening symptoms. difficulty hearing or mild hearing loss.In mild cases, or when ear barotrauma first starts, a person may experience: Chronic cases occur for an extended period and have the potential to cause further complications. Acute cases are quite common and are generally harmless. However, people may experience additional symptoms when ear barotrauma results from illness or a blockage in the middle ear.ĭoctors classify ear barotrauma as either acute or chronic. When air pressure changes are responsible for ear barotrauma, it often goes away as soon as the air pressure outside has normalized, and should not cause any further symptoms. Initially, a person may only feel an uncomfortable pressure inside the ear, but sometimes the condition can progress and worsen. The symptoms of ear barotrauma differ according to how severe and prolonged it is. Share on Pinterest Scuba diving may cause ear barotrauma.
