Sudden deafness


The annual number of new cases is estimated at 10-20 cases per 100,000 inhabitants. A more recent German study increases these figures to 160 new cases per 100,000 inhabitants.

Characteristics of Sudden Deafness

Clogged ear sensation, hearing loss, tinnitus. The hearing loss is confirmed with the audiogram by the ENT doctor.

Spontaneous evolution

HBOT clinical studies

Practical use of HBOT

HBOT should be started as soon as sudden hearing loss occurs. 15 consecutive sessions are prescribed until the first auditory evaluation. HBOT still appears to be effective in cases where other forms of treatment have failed. However, HBOT should be started as soon as failure of the first treatment has been established. Many patients come to us too late or have to give up treatment for economic reasons.
