Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Age between 12 and 75 years Unilateral idiopathic sudden sensorineural hearing loss diagnosed by Pure tone test, CT and MRI Symptoms of sudden deafness occur within ≥ 7 days and, after conventional treatment, the average thresholds at 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz are ≥ 80 dBHL
