Presentation
Diagnosis is based on the clinical presentation, a sensorineural defect detected with tuning fork tests and on hearing tests. ISSHL should be treated as a medical emergency and an urgent consultation of an otolaryngologist is indicated. [books.google.com]
ABSTRACT: Primary care providers should obtain hearing testing whenever a patient presents with a sudden change in hearing. [consultant360.com]
Case Presentation A 67 years old female patient, who had hypertension and type II diabetes mellitus for a long time, presented to the emergency clinic with a three weeks history of exertional chest pain. [omicsonline.org]
Tinnitus is present in the ear to a variable degree, and the hearing loss sometimes is preceded by the onset of tinnitus. Vertigo or disequilibrium is present to a variable degree in approximately 40% of patients. [otologytextbook.net]
In our study, 21 out of 37 patients presented within 3 days. Delay in presentation and thus in starting treatment is a negative prognostic factor as concluded by Bullo et al. [8]. [ejo.eg.net]

Hearing Impairment
This kind of hearing impairment is often temporary. After some time the trauma will stop. Permanent acoustic trauma If the acoustic trauma continues, it will typically lead to hearing impairment within a relatively narrow frequency around 4 kHz. [hear-it.org]
Stem Cell Treatment Stem Cells as a form of treatment for hearing impairment is a relatively new concept. [tinnituspill.org]

Sensorineural hearing loss (SNHL) or nerve deafness can be defined as a type of hearing impairment that is caused due to dysfunction of the sensory receptors present in the inner ear. [news-medical.net]

Workup
The role of imaging is still not well defined in SSNHL workup as it does not seem to affect treatment much; however, to label SSNHL as idiopathic, MRI is essential to rule out vestibular Schwannoma as it is found in about 2% of SSNHL and has been associated [ejo.eg.net]
Treatment
There is research evidence, albeit limited, to support the early and short term use of corticosteroids in patients with no contraindications to steroid treatment. [books.google.com]
All reports describing treatments indicated that earlier initiation of treatment was associated with better hearing outcome. [masseyeandear.org]
Optimal treatment is still under research and controversies exist but treatment versus non-treatment and early initiation of treatment is proved to give better result. 1. [entcare.wordpress.com]

The sooner a response is seen, the better the overall prognosis. Patients who get all the way to the end of their course of steroid treatment with no demonstrable benefit have a poor prognosis for further hearing recovery. [masseyeandear.org]
Reduced speech discrimination appears to carry a poor prognosis. [otologytextbook.net]
Some 35 patients had mild idiopathic hearing loss and prognosis was relatively good. [ci.nii.ac.jp]
Etiology
Etiology There are three main causes of acquired sensorineural hearing loss: ototoxic drugs (ototoxicity); overstimulation (acoustic trauma); and age (presbycusis). [cochlea.eu]
Finally a microemboli due to postoperative hypercoagulability could be the etiologic factor. [omicsonline.org]
Still other treatment ideas are directed at other presumed etiologies. [otologytextbook.net]

The best epidemiologic data suggest it strikes one person per 5,000 per year. In metropolitan Boston, for example, this would mean that 300 or 400 people per year develop idiopathic SSNHL. It’s a fairly common problem. [enttoday.org]

Pathophysiology
The postulated pathophysiology for the SSNHL with dizziness after head trauma has four possible pathways. First, microfractures resulting from the head trauma could account for the labyrinthine concussion. [ejao.org]
Note - the following pages concern either clinical aspects of hearing loss, or experimental results that describe the pathophysiological and molecular mechanisms that cause it. [cochlea.eu]
Various etiologies had thus been proposed to look into the pathophysiology of this phenomenon and thus offer a possible preventive or curative measure. [omicsonline.org]
Actually, it is well known that two different pathophysiological mechanisms are involved: mechanical and metabolic. [latunisiemedicale.com]

Blocking (inhibiting) these mechanisms would prevent further cell death and thus the size of the damage could be limited. AM-111 is a peptide that inhibits (blocks) one of these biochemical mechanisms. [ema.europa.eu]
