To evaluate video-head-impulse test (vHIT) results in normal subjects, to determine the normative values of vHIT for vestibulo-ocular reflex (VOR) and characterise catch-up saccades (CSs).Prospective cohort study.Tertiary care academic referral centre.Fifty healthy subjects with no history vestibular impairment, ten each their 20's, 30's, 40's, 50's 60's, underwent vHITs lateral semicircular canal plane.vHIT gains incidence amplitudes covert overt CSs.The mean gain was 1.02 ± 0.07, asymmetry...
Abstract Objective: To evaluate the therapeutic efficacy of intratympanic dexamethasone (ITD) injections added to systemic steroids in patients with idiopathic sudden sensorineural hearing loss (HL). Materials and Methods: A total 120 diagnosed HL were treated ITD (0.3 mL on days 1, 3, 5) plus 48 mg methylprednisolone (ITD group) or alone (control group). Results: The recovery rate after treatment was 73.3% group 70.0% control group. Although improvements pure‐tone average same two groups,...
Background Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular disorder, and its prevalence substantial. While primary BPPV has been well studied, understanding of secondary still limited. Objective To investigate clinical characteristics in a national multicenter retrospective analysis. Methods The study involved analysis medical records from 17 institutions across South Korea, between January June 2022. We evaluated features, presumed etiologies,...
Objectives We investigated changes in video head impulse test (vHIT) gains and corrective saccades (CSs) at the acute follow-up stages of vestibular neuritis to assess diagnostic value vHIT. Study Design Case series with chart review. Setting Tertiary medical center. Subjects Methods Sixty-three patients who underwent vHIT an initial presentation approximately 1-month were included. gains, gain asymmetry (GA), peak velocities CS, interaural difference CS (CSD) analyzed. Results Mean...
<h3>BACKGROUND AND PURPOSE:</h3> According to recent research, modern MR imaging can detect the presense of abnormalities on labyrinthine. Our aim was report patterns and prognostic role abnormal findings labyrinthine in patients with sudden sensorineural hearing loss. <h3>MATERIALS METHODS:</h3> This study comprised 113 who were diagnosed unilateral loss underwent 3T imaging, including pre-/postcontrast 3D fluid-attenuated inversion recovery T1-weighted imaging. We analyzed correlated them...
To report the incidence of vestibular migraine (VM) in patients with Ménière's disease (MD) and investigate whether management outcomes MD differ by association VM.Retrospective cohort study.Tertiary care academic center.MD (n = 251) with/without VM who were managed for 5 years a dizziness clinic.Influence on hearing at latest follow-up stepwise options.Incidence was 35% patients. more common women than men (40 vs. 22%) probable definite (43 29%). Bilateral frequent coexistence without (14...
Objectives To describe vertical and horizontal components of head‐shaking nystagmus ( HSN ) in various vestibular disorders. Design Retrospective case review. Setting Tertiary care academic referral centre. Participants Head‐shaking was assessed 66 neuritis VN patients at acute (<7 days) follow‐up (2 months), 65 M eniere's disease MD 76 migrainous vertigo MV interictal period. Main outcome measures categorised as pure horizontal, or mixed. Horizontal classified monophasic biphasic paretic...
Objectives We evaluated vestibular function test results in migraine (VM) patients, including caloric, evoked myogenic potential (VEMP), and dynamic posturography measurements assessed their relationship with treatment responses. Study Design Retrospective case series review. Setting Tertiary referral center. Methods investigated a cohort of 80 VM patients who had suffered recurrent vertigo attacks for more than 6 months. A combination lifestyle modifications prophylactic medications were...
Objective: To report the prevalence of hearing loss (HL) and associated factors in a nationwide study. Design: Cross-sectional Study sample: We investigated HL 10,845 participants ≥12 years age analysed with from 7434 ≥40 age. Results: The worse ear was 21.9% (1.2% youngest 81.9% oldest) that better 12.5% (none 65.3% oldest). Based on HL, more common men, related low education income. In univariable analysis, hypertension, smoking, diabetes, depressive mood, stroke or cardiac disease,...
Conclusion: Benign paroxysmal positional vertigo (BPPV) could be treated with specific maneuvers for the involved canals. Management on a daily basis gave earlier relief than weekly treatment, especially in apogeotropic BPPV. Apogeotropic and multi-canal BPPVs were related to increased numbers of follow-ups trauma was recurrence. Objective: We aimed report short-term outcomes our protocol BPPV evaluate factors influencing results Methods: In 210 patients, posterior semicircular canal (PSCC),...
Sodium selenite is a trace element essential for many physiological functions in the body. It involved various biological processes; it acts as cofactor antioxidant enzymes that protect against free radicals and reported to limit metal-mediated oxidative DNA damage. In present study, we investigated effect of sodium on neomycin ototoxicity wild-type transgenic zebrafish (Brn3C: EGFP). Five or six days post-fertilization, larvae were co-exposed 125 μM concentrations (10 μM, 100 250 500 μM) 1...
Objectives Direction-changing positional nystagmus (PN) was considered to indicate the presence of benign paroxysmal vertigo involving lateral semicircular canal in most cases. We investigated incidence PN on supine head-roll test and compared characteristics patients with vestibular neuritis (VN) Meniere disease (MD). Methods A retrospective review patients, who were diagnosed unilateral VN or definite MD between September 2005 November 2011, conducted. Sixty-five 65 enrolled. Eye movements...
Objectives: To evaluate whether video head impulse test (vHIT) gains are dependent on the measuring device and method of analysis. Study Design: Prospective study. Methods: vHIT was performed in 25 healthy subjects using two devices simultaneously. were compared between these instruments five different methods comparing position velocity during movement intervals. Results: The produced gain results with same There also significant differences measured analytical methods. analytic that...
<b><i>Objectives:</i></b> Severe-to-profound sudden sensorineural hearing loss (SSNHL) has a poor prognosis. We aimed to compare the efficacy of simultaneous and sequential oral intratympanic steroids for this condition. <b><i>Methods:</i></b> Fifty patients with severe-to-profound SSNHL (>70 dB HL) were included from 7 centers. The group (27 patients) received steroid injections 2 weeks. (23 was treated weeks subsequent Pure-tone averages...
