OBJECTIVE: Various types of laser, microdrill, and perforator are effectively used in the surgical treatment of otosclerosis. However, they have certain disadvantages along with advantages. The aim of this study was to evaluate the effects of carbon dioxide (CO2) laser and perforator stapedotomy techniques on audiological outcomes and postoperative vestibular functions via videonystagmography (VNG). MATERIALS AND METHODS: This prospective and randomized clinical study was conducted in an academic tertiary medical center...

OBJECTIVE: The aim of this study is to define an experimental model in order to promote the functional recovery of the nerves using grafts with vascular support (Vascular Nerve Grafts - VNG). The aim of this study is to define, on an experimental model in normal recipient bed, whether the functional recovery with VNG is superior to that obtained non-vascularized graft (NNG). METHODS: Twenty male rabbits, which underwent dissection of sciatic nerve, were later treated by reinnervation through an autograft...

CONCLUSION: It was found that JIR children had potential sensory neural hearing loss and vestibular affection. Therefore, this study recommends: early complete audiologic evaluation of JIA child followed by regular follow-up, including TOAEs, extended high-frequency audiometry, and VNG. This follow-up is important for preliminary diagnosis and management in order to prevent the negative impact of hearing loss on a child's life. OBJECTIVE: The aim of this study was to assess hearing in children with Juvenile idiopathic arthritis (JIA) and compare them with a healthy control group...

OBJECTIVES/HYPOTHESIS: To evaluate the clinical features of audiologic impairment and its relationship with the nasal, vestibular, and rheumatologic profile in a cohort of patients with eosinophilic granulomatosis with polyangiitis (EGPA), formerly named Churg-Strauss syndrome. STUDY DESIGN: Prospective cross-sectional study. METHODS: Thirty-nine patients with EGPA, considered controlled according to the Birmingham Vasculitis Activity Score and the Vasculitis Damage Index, underwent a complete audiologic evalutaion with otomicroscopy, impedance audiometry, speech audiometry, and auditory brainstem responses; rhinologic evaluation was made by means of fiberoptic endoscopy and nasal cytology; the clinical evaluation was completed with analysis of the facial function and, in patients with referred vertigo, with videonystagmography (VNG)...

INTRODUCTION: The aim of this work was to evaluate the diagnostic value of the neck torsion test in VNG, Doppler ultrasonography and brainstem auditory evoked potentials in patients with vertigo and/or hearing loss due to intracranial vascular malformations. MATERIAL AND METHODS: The study covered 47 patients, 30 female and 17 male (mean age, 55.5 years; range, 19-74 years) with vertigo and/or hearing disorders and the asymmetry of vertebral arteries. Each patient underwent a subjective examination, an otolaryngological examination, otoneurological diagnostics, VNG with gaze tracking in the straight ahead position and in the 600 left and right neck torsion, the neck torsion test, audiological diagnostics including I-, III- and V-wave latency of the brainstem evoked potentials in the straight ahead position and the right ear stimulation in the 600 right neck torsion and the left ear stimulation in the neck torsion to the left, Doppler ultrasonography with measuring the diameter of vertebral arteries and the velocity of the blood flow in these vessels with the use of the neck torsion test...

BACKGROUND: The differential diagnosis of a dizzy patient >4 yrs old is often aided by videonystagmography (VNG) testing to provide a global assessment of peripheral and central vestibular function. Although the value of a VNG evaluation is well-established, it remains unclear if the VNG test battery is as applicable to the pediatric population as it is for adults. Oculomotor testing specifically, as opposed to spontaneous, positional, and caloric testing, is dependent upon neurologic function...

The objective of this study is to report the surgical outcome after middle fossa approach (MFA) plugging in patients suffering from a superior semi-circular canal dehiscence (SCD) syndrome. This is a retrospective case review. Tertiary referral center. Sixteen ears in 13 patients with a SCD syndrome suffering from severe and disabling vestibular symptoms with a bony dehiscence on CT scan >3 mm and decreased threshold of cervical vestibular evoked potentials (cVEMPs). We assessed preoperatively: clinical symptoms, hearing, cVEMPs threshold, size of dehiscence and videonystagmography (VNG) with caloric and 100 Hz vibratory tests...

OBJECTIVES: The aim of the study was to assess the usefulness of bedside examination for screening of vestibular and balance system for occupational medicine purposes. Study group comprised 165 patients referred to Audiology and Phoniatric Clinic due to vestibular and/or balance problems. Caloric canal paresis of 19% was the cut off value to divide patients into 43 caloric-positive vestibular subjects and 122 caloric-negative patients. The latter group comprised 79 subjects revealing abnormalities of videonystagmographic (VNG) oculomotor tests (central group) and 43 subjects with normal VNG...

Introduction Vertigo can be due to a variety of central and peripheral causes. The relative incidence of central causes is underestimated. This may have an important impact of the patients' management and prognosis. Objective The objective of this work is to determine the incidence of central vestibular disorders in patients presenting to a vestibular unit in a tertiary referral academic center. It also aims at determining the best strategy to increase the diagnostic yield of the patients' visit. Methods This is a prospective observational study on 100 consecutive patients with symptoms suggestive of vestibular dysfunction...

Surface-enhanced Raman spectroscopy (SERS) technique was used to analyze the Raman peaks of thiabendazole pesticides in the present paper. Surface enhanced substrates of silver nanoparticle were made based on microwave technology. Raman signals of thiabendazole were collected by laser Micro-Raman spectrometer with 514. 5 and 785 nm excitation wavelengths, respectively. The Raman peaks at different excitation wavelengths were analyzed and compared. The Raman peaks 782 and 1 012 at 785 nm excitation wavelength were stronger, which were C--H out-of-plane vibrations...

OBJECTIVE: Enlarged vestibular aqueduct (EVA) is the most common inner ear malformation. While a strong correlative relationship between EVA and hearing loss is well established, its association with vestibular dysfunction is less well understood. In this study, we examine the effects of EVA on the vestibular system in patients with EVA. STUDY DESIGN: Prospective, cross-sectional study of a cohort ascertained between 1999 and 2013. SETTING: National Institutes of Health Clinical Center, a federal biomedical research facility...

CONCLUSIONS: Although combined utricular and canal paresis has been described previously, this is the first report of canal hyperactivity associated with utricular hypofunction. Unsteadiness and swaying were the most common symptoms, and patients with shorter duration of symptoms also had positional vertigo. We propose that this syndrome is a variant of utricular dysfunction and should be considered in the differential diagnosis of peripheral vestibular disorders. OBJECTIVE: To describe a syndrome of instability associated with utricular dysfunction and hyperactive caloric responses...
