Sensorineural hearing loss is a hearing impairment that results from damage to the inner ear. The most common cause of sensorineural hearing loss is age-related degeneration and damage to the cells in the cochlea, the part of the ear responsible for detecting sound vibrations and sending this information to the brain. However, other common causes include exposure to loud noises, ototoxic medications, certain diseases, infections, or trauma to the head or ears, leaving many searching for effective sensorineural hearing loss treatment. Although many treatments have arisen over the years, hyperbaric oxygen therapy (HBOT) has emerged as a promising treatment option for sensorineural hearing loss. At NexGen Hyperbaric in Edwards, CO, our team of scholarly physicians is constantly monitoring new research to find increasingly advanced applications for HBOT. Here, we share our current findings on sensorineural hearing loss and HBOT studies. We explain what hyperbaric treatment is and how it works, as well as provide an overview of the evidence supporting its use for the treatment of sensorineural hearing loss.
