Ear, Nose and Throat Conditions

Brief Description and Purpose

The inner ear is one of the most sensitive and finely organized sensory mechanisms in the human body. The hair cells of the cochlea, the auditory sensory receptors, and the blood vessels that supply them respond immediately to any disruption in blood flow or oxygenation, and because they lack collateral circulation, even transient ischemia can leave permanent effects.

Hyperbaric oxygen chamber therapy is incorporated into the otological field as one of the most well-documented applications of the method. The rationale is simple and scientifically sound: by restoring oxygenation to the cochlea and auditory nerve, the affected tissue is given the biological capacity to recover, provided that treatment is initiated promptly.

Always in an adjunctive role and under otological supervision.

Key Characteristics of the Treatment

In otolaryngological conditions, hyperbaric oxygen chamber therapy utilizes a fundamental physiological mechanism: the inner ear is supplied by a single end artery, the cochlear artery, without collateral vessels capable of compensating for any obstruction or ischemia.

This means that any disruption in blood flow directly and inevitably affects the oxygenation of cochlear tissue.

Hyperoxygenation under increased pressure allows oxygen to reach the cochlea through dissolution in the aqueous compartments of the inner ear, independently of blood flow.

At the same time, endolymphatic pressure is reduced, the inflammatory response associated with many otological conditions is inhibited, and regenerative mechanisms are activated in cochlear hair cells that are in a state of functional inhibition.

Scientific Basis

Sudden sensorineural hearing loss is the most well-documented otological indication for the use of hyperbaric oxygen. The UHMS and ECHM classify it as an approved indication, emphasizing that effectiveness is directly related to the speed of initiation; early intervention, within the first few days, produces significantly better outcomes than delayed treatment.

For tinnitus and other otological conditions with an ischemic basis, the scientific evidence is still developing but encouraging.

The common thread across all applications is the same pathophysiological mechanism: restoring oxygenation to a tissue that depends absolutely on a continuous and adequate supply of oxygen to function.
