  Usually, within a few hours to a few weeks evidence of eighth nerve involvement appears, manifested by tinnitus, nausea, vomiting, vertigo, and bilateral progressive loss of hearing. [jamanetwork.com]

  The vestibuloauditory manifestations consist of a Ménière’s-like disease including vertigo, nausea, vomiting, tinnitus, and hearing loss. [jrheum.org]

  The administration of a combined immunosuppressive treatment resolved ocular inflammation, dizziness, nausea, and vertigo but gave little results in controlling progressive hearing loss. [ojrd.biomedcentral.com]

  Cogan syndrome is a systemic disease manifesting interstitial keratitis, sensorineural hearing loss, tinnitus, and rotatory vertigo. Renal complications of this syndrome are very rare. [ncbi.nlm.nih.gov]

  Shortly following these ocular (eye) symptoms, patients develop bilateral audiovestibular (ear) symptoms, including hearing loss, vertigo (dizziness) and tinnitus (ringing in the ears). [aarda.org]

• Fluctuating Hearing Loss

  The histopathologic manifestations appear to explain the audiovestibular dysfunction that has been reported in Cogan's syndrome, including bilateral fluctuating hearing loss, tinnitus, and severe vertigo. [ 2, 4 ]. [pubs.sciepub.com]

  However, every attempt to decrease and stop the steroid treatment has been followed by fluctuating hearing loss and conjunctivitis. [pediatrics.aappublications.org]

The prognosis of typical CS is excellent with life-threatening aortic insufficiency (AI) developing in only 10% of reported cases. Serious systemic necrotizing vasculitis (SNV) rarely, if ever, complicates typical CS. [ncbi.nlm.nih.gov]

Atypical CS tends to be more aggressive and has a worse prognosis [1]. [medcraveonline.com]

Prognosis The prognosis is dominated by the risk of definitive deafness and by cardiovascular complications, notably aortic insufficiency. Severe visceral involvement or death related to cardiac or vascular involvement is unusual. [orpha.net]

Although CSy is considered to be an autoimmune disease and is associated with IBD, immunomodulatory IBD maintenance treatment and even anti-TNF therapy do not seem to prevent disease onset. [zora.uzh.ch]

There are similar autoimmune diseases such as Menieres, that are more widely recognized and diagnosed, but treatment of Cogan's Syndrome requires an immediate diagnose to prevent the disease from doing permanent damage. [amazon.com]
