“…This number includes a total of 919 etiologic and pathologic studies. Many different causes of Mé-nière's disease have been proposed, such as an anomaly or variant vestibular aqueduct [11][12][13] , local autoimmune disorder [14][15][16][17] , viral infection [19] , water metabolic disorder [18] , and gene mutation [20][21][22] ; however, the exact cause remains unknown. Although we cannot rule out the possibility that Ménière's disease is a hydrops complex of 11.7% 88.3% -n = Number of audiogram pairs; recovery = shift to a milder category; worsening = shift to a more severe category.…”

“…Investigators interested in the disease have looked at endolymphatic sac pathology [8][9][10] , morphology of the vestibular aqueduct [11][12][13] , local allergy and immunology [14][15][16][17] , water metabolism [18] , viral infection [19] , and gene mutation [20][21][22] . It is quite striking that causes of the disease and effective therapies are still unknown despite the vast number of experimental and clinical studies conducted over the past half century.…”

Purpose: To identify personal causative factors for Ménière’s disease. Procedures: Patterns of hearing loss progression were studied in patients with Ménière’s disease and low-tone sensorineural hearing loss, and the involvement of stress and the relation of stressors to the onset or progression of the disease were analyzed. Results: Low-tone loss recurred in 40% of patients even after hearing was restored, and low-tone loss progressed to high-tone loss after frequent repetitions of recovery and recurrence. High-tone loss tended to proceed to all-tone loss. Eighty percent of patients reported that stress was involved or deeply involved in the onset or progression of the disease. Common causative stressors were business-related pressure, insufficient sleep, and troubles at the workplace or at home. Conclusions: The present findings indicate that recovery and recurrence may be influenced by the strength and duration of stress that is produced when patients do not feel rewarded for engrossment in their work or for self-inhibiting behaviors.

What is the Current and Potential Future Role of Imaging in the Investigation of Patients with Suspected Meniere's Disease?

Meniere's disease (MD) represents a diagnostic challenge. It's symptoms of episodic vertigo, hearing loss, tinnitus, and a sense of aural fullness share overlap with multiple other conditions. It remains a diagnosis of exclusion, with imaging only used to rule out other pathologies, notably acoustic neuroma. Technological advance has brought increased resolution to the inner ear. In the future it is likely that MD will become a radiological diagnosis.Keywords: Hydrops; Imaging; Dizziness; Vertigo Meniere's DiseaseCurrently, the primary role of imaging in the investigation of suspected MD is to exclude other pathology. MD can present with asymmetrical hearing loss. In such circumstances it is usual to perform an MRI to exclude an acoustic neuroma or other forms of cerebellopontine angle tumour. The guidance on precisely when a patient requires an MRI to investigate asymmetrical SNHL is less clear. A comparison of eight screening protocols found that the best compromise between sensitivity and specificity was achieved by a criterion requiring either a 20 dB asymmetry at two neighbouring frequencies, or 15 dB asymmetry at two frequencies between 2 and 8 kHz [1]. Similarly, in the vertiginous patient an MRI can be used to exclude, space occupying lesions such as endolymphatic sac tumours, cholesteatoma fistulas, and brain metastasis [2].In the acute setting, the symptoms of a Meniere's attack can be mimicked by an anterior inferior cerebellar artery (AICA) stroke, which shares the symptoms of vertigo, tinnitus, deafness. The other symptoms of hemiplegia, and facial weakness offer greater distinction. However, all patients presenting with such a first episode of such symptoms should have a Computed Tomography (CT) scan to exclude a central cause [3]. The symptoms of AICA occlusion, display the lack of collateral vessels to the inner ear and its high metabolic rate, an anatomical fact which may have a bearing on the pathophysiology of MD.The future importance of imaging in the investigation of the suspected MD patient will depend on the other diagnostic modalities with which it is competing. Therefore it is necessary to comparatively discuss their diagnostic accuracy.A pure tone audiogram (PTA) is a basic step in the Meniere's diagnosis. MD classically produces a fluctuating low frequency hearing loss that becomes permanent as the disease progresses. However, it can cause many other patterns of hearing loss, which may mimic differentials such as otosclerosis, or noise induced losses [4]. Electronystagmography(ENG), is another routine investigation as MD causes a reduced vestibular response in the ear affected. However, it has limited sensitivity as recent work shows only a 50% positive rate in confirmed MD cases [5].Electrocochleography (ECoG) provides electrophysiological verification. An elevated summating potential/ nerve action potential of greater than 35% is a sign of MD. However, whilst a useful part of the diagnostic battery, specificity and sensitivity remains low particularly when performed in betwee...

“…Compared with normal controls, the endolymphatic duct and sac may be difficult to visualize on high-resolution T2-weighted imaging in MD. [30][31][32] The gap between the vertical part of the posterior semicircular canal and the posterior fossa may also be narrower than that in healthy subjects (2.9 mm in MD versus 3.8 mm in controls) (Fig 7). 33 Patients with MD usually have high-intensity tinnitus, the severity of which may increase with longer duration of the disease; a higher MD stage; and the presence of bilateral disease, hearing impairment, or hyperacusis.…”

SUMMARY:Tinnitus affects 10% of the US general population and is a common indication for imaging studies. We describe a sequential compartment-based diagnostic approach, which simplifies the interpretation of imaging studies in patients with tinnitus. The choice of the initial imaging technique depends on the type of tinnitus, associated symptoms, and examination findings. Familiarity with the pathophysiologic mechanisms of tinnitus and the imaging findings is a prerequisite for a tailored diagnostic approach by the radiologist.ABBREVIATIONS AV ϭ arteriovenous; AVF ϭ arteriovenous fistula; AVM ϭ arteriovenous malformation; CPA ϭ cerebellopontine angle; DSA ϭ digital subtraction angiography; IAC ϭ internal auditory canal; ICA ϭ internal carotid artery; IIH ϭ idiopathic intracranial hypertension; MD ϭ Mé niè re disease; NSAIDs ϭ nonsteroidal anti-inflammatory drugs; PSA ϭ persistent stapedial artery; TMJ ϭ temporomandibular joint.
