Abstract Background Patients suffering from vestibular migraine (VM) are known to have various vestibular test abnormalities interictally and ictally. Recently, vestibular evoked myogenic potentials (VEMPs) have become accepted as a valid method for otolith function assessment. Many studies have identified various vestibular symptoms and laboratory abnormalities in migraineurs. Since migraineurs with no accompanying vestibular symptoms might exhibit subclinical vestibular dysfunction, we investigated vestibular function using ocular and cervical VEMPs in migraine patients. The aim was to study cervical VEMP and occular VEMP in migraineurs with and without vestibular symptoms interictally. Results Migraine and VM patients showed significantly longer P13 latency of cVEMP compared to controls. A statistically significant cVEMP interaural P13 latency difference was found in VM compared to healthy controls. Cervical VEMP N23 latency, peak-to-peak amplitude, interaural N23 latency, and amplitude asymmetric ratio did not show any significant difference in migraine and VM patients compared to healthy controls as well as no significant difference across the three groups regarding oVEMP parameters. Conclusions Abnormal interictal cVEMP results in migraineurs might indicate subclinical vestibulo-collic pathway dysfunction.

Vestibular Symptoms

Vestibular migraine (VM) has emerged as one of the major vestibular syndromes. Although probiotics have exhibited beneficial effects on migraine headache, its effect on VM is not clear. This trial aimed to investigate the treatment efficacy of the probiotic Lactobacillus casei Shirota (LcS) on symptoms of VM. 247 VM patients were enrolled, of which 204 eligible patients receiving either LcS or placebo on a daily basis completed the 4 month study. They were re-visited at 2 and 4 months after study initiation to assess treatment outcomes. The primary endpoints were vestibular symptoms, evaluated by the number of vertiginous attacks during the past week, the Vertigo Severity Score (VSS), and Dizziness Handicap Inventory (DHI) scores. The secondary endpoints were anxiety and depressive symptoms, evaluated using Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) scores. Efficacy of LcS over placebo was not obvious at 2 month follow-up. At 4 month follow-up, while both LcS and placebo groups of VM patients displayed alleviated symptoms, the extents of the improvements were significantly better in LcS group than those of placebo group, with regard to vestibular symptoms using DHI and VSS, as well as anxiety and depressive symptoms using BAI and BDI. Although placebo effect cannot be ignored in intervention for VM patients, the probiotic LcS still exhibits considerable efficacy against VM symptoms over a 4 month study period, supporting further clinical study of a larger and more diverse cohort.

Objectives: The purpose of this study was to investigate the correlation between grades of endolymphatic hydrops (ELH) and clinical characteristics and determine the detailed clinical characteristics of Ménière’s disease (MD) patients with evidence of hydrops based on magnetic resonance imaging (MRI). Methods: One hundred ninety-eight MD patients (396 ears) with MRI evidence of hydrops were included. ELH grades were evaluated using the Nakashima grading standard. Correlations between the extent of ELH and clinical features were evaluated. Detailed clinical characteristics were analyzed to assess the clinical diagnostic criteria. Results: Of 198 patients, ELH was observed in 100% of cases on the clinically affected side and 8.6% of cases on the asymptomatic side. In addition, 98.5% of ELH was classified as moderate or significant grade. Low-frequency hearing loss was significantly correlated with the extent of both vestibular and cochlear hydrops, whereas the vertigo attack frequency showed no significant correlation with ELH grades. The disease duration of MD with bilateral ELH was longer than that with unilateral ELH. The clinical characteristics were variant and did not completely fit the proposed diagnostic criteria. Conclusions: MRI findings have relevance to the clinical severity, to a certain extent, but not vestibular symptoms. The proposed diagnostic criteria based on clinical characteristics may be partially effective; analysis of the detailed clinical characteristics of MD was meaningful. Diagnosis of MD based on both MRI and clinical symptoms could facilitate an early diagnosis.

Abstract The cases of 16 patients with acoustic neurinomas confined to the intracanalicular area are presented. These represent 2.7% of the 600 patients with acoustic neurinomas consecutively operated upon at the Neurosurgical Clinic at Nordstadt Hospital during the last 8 years. The comparatively earlier onset of vestibular symptoms and signs was characteristic of this group and precipitated diagnosis. The diagnostic reliability of magnetic resonance imaging was at least equivalent to that of air computed tomographic cisternography. Complete tumor removal was accomplished via the suboccipital approach in all patients, with 100% preservation of facial nerve and facial function; the cochlear nerve was preserved anatomically in 100% of the patients and functionally in 57%. No recurrence has occurred during follow-up periods of up to 8 years in all 16 patients. A broad spectrum of the current literature is considered, and purely intracanalicular acoustic neurinomas are discussed with regard to clinical characteristics, diagnostic steps—including neuroradiological and neurophysiological approaches—and surgical treatment and results.

Results Of Surgery

A perilymphatic fistula of a labyrinthine window may initially present with various cochlear or vestibular symptoms. Vestibular perilymph leaks can occur spontaneously with or without hearing loss and are most readily diagnosed by a positive Hennebert's sign. Surgical correction is indicated and should initially consist of grafting of the perilymph leak. A significant incidence of recurrence warrants further investigation of grafting materials and techniques.

Autoimmune Hearing Loss

<b><i>Introduction:</i></b> The aim of this study was to illustrate clinical and audiological patterns of hearing impairment in patients with autoimmune hearing loss (AIHL). <b><i>Methods:</i></b> Fifty-three patients with AIHL were retrospectively recruited, and a tapering schema of steroid treatment was administered in all these patients. The diagnosis of AIHL was essentially based on clinical symptoms, such as recurrent, sudden (sensorineural hearing loss [SSHL]), fluctuating, or quickly progressing (&#x3c;12 months) SSHL (uni-/bilateral), in association with the coexistence of autoimmune diseases, high antinuclear antibodies (ANA) and the presence of human leukocyte antigen (HLA) B27, B35, B51, C04, and C07. Logistic regression analysis was applied to correlate the clinical data and laboratory features of AIHL with final outcomes. <b><i>Results:</i></b> The onset of AIHL was mainly progressive (49%), followed by SSHL (39.6%) or fluctuating (11.3%). The pure-tone audiogram showed more commonly a downsloping pattern (42.6% of ears), but also an upsloping, flat, cookie-bite, or inverse cookie-bite shape. Bilateral progressive AIHL was more frequently simultaneous (23 patients) than heterochronous (4 patients). Nineteen patients (35.8%) showed a favorable response to steroid therapy. The presence of recurrent, bilateral SSHL versus recurrent, unilateral SSHL had statistically negative effect on hearing recovery (OR = 0.042, <i>p</i> &#x3c; 0.05). The heterochronous bilateral SSHL may have better prognosis than simultaneous bilateral SSHL (OR = 10.000, <i>p</i> = 0.099). The gender, age, concomitant autoimmune disease, high ANA, HLA alleles, tinnitus, and vestibular symptoms had no statistical effect on a favorable outcome of AIHL. <b><i>Conclusions:</i></b> A bilateral, simultaneous, and progressive hearing loss combined with downsloping audiogram occurred more often in patients with AIHL. Bilateral simultaneous SSHL with recurrences represents the worse prognostic form of AIHL.

Vestibular Symptoms

AbstractPersistent postural-perceptual dizziness (PPPD) was defined for the International Classification of Vestibular Disorders in 2017. It is a chronic vestibular disorder that manifests with waxing and waning symptoms of dizziness, unsteadiness, or nonspinning vertigo that last for 3 months or more and are exacerbated by upright posture, active or passive motion of self, and exposure to environments with complex or moving visual stimuli. Triggers of PPPD include a wide variety of conditions that may cause vestibular symptoms or disrupt balance functioning, including neuro-otologic and other medical conditions and psychological distress. The diagnosis is made by identifying key symptoms in patients' histories and conducting physical examinations and diagnostic testing of sufficient detail to establish PPPD as opposed to other illnesses. Ongoing research is providing insights into the pathophysiological mechanisms underlying PPPD and support for multimodality treatment plans incorporating specially adapted vestibular rehabilitation, serotonergic medications, and cognitive-behavior therapy.

Conductive Hearing

Otic capsule dehiscences create a pathological third window in the inner ear that results in a dissipation of the acoustic energy consequent to the lowered impedance. Superior semicircular canal dehiscence (SSCD) was identified by Minor et al in 1998 as a syndrome leading to vertigo and inner ear conductive hearing loss. The authors also reported the relation between the dehiscence and pressure- or sound-induced vertigo (Tullio’s phenomenon). Prevalence rates of SSCD in anatomical studies range from 0.4% to 0.7% with a majority of patients being asymptomatic. The observed association with other temporal bone dehiscences, as well as the propensity toward a bilateral or contralateral “near dehiscence,” raises the question of whether a specific local bone demineralization or systemic mechanisms could be considered. The present report regard a case of a patient with a previous episode of meningitis, with a concomitant bilateral SSCD and tegmen tympani dehiscence from the side of meningitis. The patient was affected by dizziness, left moderate conductive hearing loss, and pressure/sound-induced vertigo. Because of disabling vestibular symptoms, the patient underwent surgical treatment. A middle cranial fossa approach allowed to reach both dehiscences on the symptomatic side, where bone wax and fascia were used for repair. At 6 months from the procedure, hearing was preserved, and the vestibular symptoms disappeared.
