If the hearing loss happens suddenly or develops over a period of up to three days, it is called sudden hearing loss.<\/p>

Sudden hearing loss may have various causes. The first aetiologic factor that must be excluded is a benign tumour of the auditory nerve, called acoustic neuroma. This is why a CT-scan or MRI is usually ordered for the case assessment.<\/p>

Perilabyrinthine fistula is another cause of sudden hearing loss, usually suspected from the history. This happens in cases of high pressure gradient between the inner ear and the middle ear cavity, as in diving. If the diver forces equalization by blowing with mouth and nose closed (forced Valsalva), and the eustachian tube is blocked, as in an upper respiratory tract infection, the pressure gradient can cause rupture of inner ear membranes and leakage of inner ear fluid in the middle ear cavity.<\/p>

Unfortunately, in the vast majority of cases, the cause of sudden hearing loss is unknown. We believe that two major etiologic categories play the most important role: The vascular and the immunologic causes. Vascular causes include contraction and occlusion of the minute feeding vessels of the inner ear, while immunologic causes refer to immunological reactions within an infection, usually viral.<\/p>

Sudden Hearing Loss is considered an otological emergency. The sooner the treatment starts, the higher the chance for recovery of hearing. There is no general consensus on its management. Several therapeutic regimens have been proposed, including:<\/p>
