History of difficult ear clearing or forced Valsalva manoeuvre: No history of eustachian tube dysfunction Low-risk dive profile: Depth >15 m, helium mixtures, helium to nitrogen gas switches, repetitive dives Isolated inner ear symptoms, or inner and middle ear on the same sides: Other neurological or dermatological symptoms suggestive of DCS
Diver clearing ears Section of the human ear, the Eustachian tube is shown in colour. Ear clearing, clearing the ears or equalization is any of various maneuvers to equalize the pressure in the middle ear with the outside pressure, by letting air enter along the Eustachian tubes, as this does not always happen automatically when the pressure in the middle ear is lower than the outside pressure.
The inner ear includes sensory organs for balance and hearing. When the inner ear is inflamed, vertigo is a common symptom. Other symptoms in adults include pain and drainage from ear or problems with hearing. [8] Symptoms in children can include excessive crying, touching at ears, drainage, and fever. [8]
Also, the diagnosis may be made in children who have mild bulging of the ear drum and recent onset of ear pain (less than 48 hours) or intense erythema (redness) of the ear drum. To confirm the diagnosis, middle-ear effusion and inflammation of the eardrum (called myringitis or tympanitis) have to be identified; signs of these are fullness ...
Balance is the result of several body systems working together: the visual system (eyes), vestibular system (ears) and proprioception (the body's sense of where it is in space). Degeneration or loss of function in any of these systems can lead to balance deficits. [1]
Cochlear hydrops preferentially affects the apex of the cochlea where low-frequency sounds are interpreted. Due to the fluid imbalance in this area, parts of the cochlea are stretched or under more tension than usual, which can lead to distortions of sound, changes in pitch perception, or hearing loss, all usually in the low frequencies.

It is especially important not to instrument ears when the skin is saturated with water, as it is very susceptible to injury, which can lead to external otitis. Avoid swimming in polluted water. Avoid washing hair or swimming if very mild symptoms of acute external otitis begin.
