“…Another limitation was that the imaging criteria employed to diagnose EVA in this study were the classic Valvassori criterion. Compared to the recent Cincinnati criteria, the lower sensitivity of Valvassori criterion may also contribute to the small sample size involved ( 38 ). Therefore, the small sample size may limit the generalizability of our findings and future prospective study involving a larger cohort of EVA patients are warranted.…”

Background: By examining the clinical features and results of video head impulse test (vHIT) and caloric tests in patients with enlarged vestibular aqueduct (EVA) presenting with vertigo, we aimed to investigate the function of angular vestibulo-ocular reflex (VOR) and its clinical implications.Methods: Nine patients with EVA manifesting with vertigo were enrolled. The medical history, audiological examination, imaging, and the results of the caloric test and the vHIT were analyzed.Results: Of the nine patients with EVA (eight bilateral and one unilateral case), five were pediatric cases. All 17 ears exhibited sensorineural hearing loss (SNHL). Enlarged vestibular aqueduct patients can present with recurrent (seven cases) or single (two cases) vertigo attack, trauma-induced (two cases), or spontaneous (seven cases) vertigo. Diminished caloric responses were observed in 77.8% (7/9) of the patients (four cases unilaterally and three bilaterally), while unilateral abnormal vHIT results in 11.1% (1/9) patients. Abnormal caloric and normal horizontal vHIT responses were found in 66.7% (6/9) of EVA patients.Conclusions: Vestibular manifestations in EVA are diverse. Enlarged vestibular aqueduct patients with vertigo can present with a reduced caloric response and normal horizontal vHIT, and this pattern of angular VOR impairment was also found in other hydropic ear diseases.

“…However, many other hypotheses have been proposed, including events that cause the variation of cerebrospinal fluid pressure [30]. HRCT is the choice of imaging modality to diagnose EVA [31]. However, MR imaging can give additional information about inner ear fluid status, which CT cannot provide.…”

In the multidisciplinary management of patients with inner ear malformations (IEMs), the correct diagnosis makes the differences in terms of clinical and surgical treatment. The complex anatomical landscape of the inner ear, comprising several small structures, makes imaging of this region particularly challenging for general radiologists. Imaging techniques are important for identifying the presence and defining the type of IEM and the cochlear nerve condition. High-resolution magnetic resonance imaging (MRI) sequences and high-resolution computed tomography (HRCT) are the mainstay imaging techniques in this area. Dedicated MRI and HRCT protocols play an important role in the diagnosis and treatment of patients with inner ear disease. The most suitable technique should be selected depending on the clinical setting. However, in cases of congenital malformation of the inner ear, these techniques should be considered complementary. Since prompt intervention has a positive impact on the treatment outcomes, early diagnosis of IEMs is very important in the management of deaf patients. This article reviews the key concepts of IEMs for clinical radiologists by focusing on recent literature updates, discusses the principal imaging findings and clinical implications for every IEM subgroup, thus providing a practical diagnostic approach.

“…The endolymphatic duct extends from the posterior aspect of the vestibule toward the posterior cranial fossa, and ends in a blind pouch, the endolymphatic sac, at the posterior margin of the petrous ridge. The bony vestibular aqueduct surrounds the endolymphatic duct and normally measures up to 1 mm at the midpoint and 2 mm at the operculum, according to the Cincinnati criteria [1].…”

“…15.4). There The most sensitive criteria is the Cincinnati criteria which defines abnormal as >0.9 mm at the midpoint or >1.9 mm at the operculum in the axial view [1]. Other criteria are using the semicircular canal as reference-enlarged if width at the proximal intraosseous portion exceeded that of the adjacent posterior semicircular canal.…”

Tinnitus and hearing loss in the adult can have profound effects on the quality of life. Tinnitus is the perception of sound when no external sound is present and may be described as ringing, buzzing, swishing, or clicking sensations. Hearing loss ranges from partial to a total inability to hear sounds. Hearing loss and tinnitus can occur concurrently or in isolation. The role of imaging is to help identify the etiology of these symptoms and evaluate for the extent of disease. 15.2 Causes of Tinnitus and Hearing Loss 15.2.1 Tinnitus Tinnitus may be categorized as (1) pulsatile or non-pulsatile, (2) primary (idiopathic) or secondary (due to another condition), and (3) subjective or objective. Evaluation of tinnitus starts with otoscopic examination to determine if there is a vascular retro-tympanic mass, audiometric examination, and review of medical history and medications. This evaluation helps to determine if imaging is necessary and if so, what study(ies) are indicated. 15.2.1.1 Pulsatile Tinnitus Causes include vascular masses (glomus tympanicum), aberrant arterial or venous anatomy, vascular malformations, and intracranial hypertension. Objective tinnitus (auscultation of a bruit on physical examination) is uncommon and has been attributed to turbulent flow in the setting of dural fistulas, atherosclerotic carotid artery disease, jugular bulb abnormalities, and large condylar or mastoid emissary veins. 15.2.1.2 Non-pulsatile Tinnitus Causes are wide ranging and include cerumen impaction, middle ear infection, mass, medications, noise-induced hearing loss, presbycusis or chronic bilateral hearing loss, hemorrhage, neurodegeneration, and spontaneous intracranial hypotension.
