Tinnitus after a dive may indicate serious cochlear damage. Discover when it requires urgent attention and what treatments exist.
Persistent ringing in the ear after diving generates great anxiety in the community. Many users describe episodes that last for days or weeks and fear they will become permanent hearing damage. The discussion covers the thresholds at which diving should be suspended, available treatments (including betahistine), and whether it is possible to continue diving with already established tinnitus without worsening the condition.
Tinnitus after a dive can be a sign of acute hearing damage. Injuries from barotrauma can damage the hair cells of the cochlea, and if the damage reaches the synapses between the inner hair cells and the auditory nerve fibers (cochlear synaptopathy), tinnitus may become chronic and irreversible. Divers who experience ringing, especially if accompanied by vertigo or hearing loss, should seek ENT care within 48 hours, as corticosteroid treatment is most effective the sooner it is initiated.
