Evolution of migraine vertigo in overlapping syndrome with ménière’s disease: Prognostic role of instrumental examination
2021
Migraine vertigo (MV) and Ménière's disease (MD) share several signs and symptoms such as tinnitus, fullness, photophobia, phonophobia, headache and vertigo spells lasting hours.The aim of the present study was to prospectively observe patients with MV with a sporadic audiological symptom evaluated with clinical examination, Vestibular Evoked Myogenic Potentials (VEMPs), ECochG and v-HIT.The finding of VEMP asymmetry, according to our cut-off of 33% of difference between sides, resulted in 20 cases, of which 6 had asymmetry of both c-VEMPs and o-VEMPS, all with development of fluctuating hearing during follow-up. ECochG was positive for endolymphatic hydrops in 12 patients.The evolution of …
Tinnitus and tinnitus disorder: Theoretical and operational definitions (an international multidisciplinary proposal)
2021
As for hypertension, chronic pain, epilepsy and other disorders with particular symptoms, a commonly accepted and unambiguous definition provides a common ground for researchers and clinicians to study and treat the problem. The WHO's ICD11 definition only mentions tinnitus as a nonspecific symptom of a hearing disorder, but not as a clinical entity in its own right, and the American Psychiatric Association's DSM-V doesn't mention tinnitus at all. Here we propose that the tinnitus without and with associated suffering should be differentiated by distinct terms: "Tinnitus" for the former and "Tinnitus Disorder" for the latter. The proposed definition then becomes "Tinnitus is the conscious a…
302 Hearing Abnormalities in Children with Fabry Disease: Data from FOS - the Fabry Outcome Survey
2005
Background: Fabry disease is an X-linked glycosphingolipid storage disorder due to a deficiency of the enzyme alpha-galactosidase A. Accumulation of substrate results in a progressive and life-threatening multisystemic disease. Early clinical manifestations include pain and gastrointestinal symptoms. Sensorineural hearing loss and vertigo are well-recognized features of the disorder, occurring in approximately 50% of adults with Fabry disease. We have investigated the audiological symptoms of Fabry disease in children using pure-tone and impedance audiometry. Methods: Symptom history was obtained using a standardized questionnaire from FOS − the Fabry Outcome Survey. Hearing was measured us…
Traumatic arteriovenous fistula as consequence of TMJ arthroscopic surgery. A case report
2016
The ocurrence of a traumatic arteriovenous fistula after arthroscopic surgery of TMJ represents an extremely rare event. Specifically, this uncommon complication has been described only in a few case reports. In this light, the most frequent symptoms showed by this disease are thrills, bruits, pulsatile tinnitus, and an expansible vascular mass. Importantly, the severity of these symptoms is also dependent on the vessels involved. With regard to the management, is important to note that the vessel ligation with surgery as well as vessel emolization with endovascular procedures have been shown to be effective in the treatment of these cases. In view of that, the present study describes a cas…
Causes of Tinnitus: Cerebrovascular Diseases
2011
1. Tinnitus can be divided into two broad groups: objective and subjective tinnitus. 2. Several layers of complexity are involved in the pathophysiology and the cause of tinnitus, and it is rarely known what causes an individual’s tinnitus. 3. Disorders that affect the brain are often accompanied by tinnitus. 4. Cerebrovascular diseases can be the cause of both objective and subjective tinnitus. 5. This chapter discusses cerebrovascular diseases as a cause of tinnitus and how it is produced.
Lateralization Effects on Cerebral Blood Flow in Patients With Unilateral Pulsatile Tinnitus Measured With Arterial Spin Labeling
2020
Purpose: To investigate cerebral blood flow (CBF) differences in patients with left- and right-sided pulsatile tinnitus (LPT and RPT) and healthy controls (HCs) to further explore the lateralization effects of PT using arterial spin labeling (ASL). Methods: ASL data from 21 RPT patients, 17 LPT patients and 21 HCs were reviewed. Voxel-wise analysis and region of interest analysis were performed to explore differences in CBF among the three groups. Tinnitus Handicap Inventory (THI) score and tinnitus duration were obtained from each patient. Results: Voxel-wise analysis showed that the CBF of the left inferior parietal gyrus was increased in both RPT and LPT patients compared with HCs (P < 0…
Cortisol suppression and hearing thresholds in tinnitus after low-dose dexamethasone challenge
2012
Abstract Background Tinnitus is a frequent, debilitating hearing disorder associated with severe emotional and psychological suffering. Although a link between stress and tinnitus has been widely recognized, the empirical evidence is scant. Our aims were to test for dysregulation of the stress-related hypothalamus-pituitary adrenal (HPA) axis in tinnitus and to examine ear sensitivity variations with cortisol manipulation. Methods Twenty-one tinnitus participants and 21 controls comparable in age, education, and overall health status but without tinnitus underwent basal cortisol assessments on three non-consecutive days and took 0.5 mg of dexamethasone (DEX) at 23:00 on the first day. Corti…
Akustikusneurinom als Ursache einer progredienten kindlichen Hörstörung
2003
Background: Neurinomas of the vestibulocochlear nerve unrelated to neurofibromatosis in children are extremely rare. Only 20 cases in children under the age of 16 are reported in the literature. Progressive unilateral hearing loss, tinnitus, vertigo and neurological deficits due to cranial nerve or brainstem compression are clinical signs. Patient and Results: We report on the case of a 12-years-old girl with an unilateral hearing loss, progressing to total deafness. Otoacoustic emissions were normal. In the MRI a large cerebellopontine angle tumor was found, identified as schwannoma of the vestibulocochlear nerve. Conclusions: The importance of MR Imaging in children with progressive unila…
Diagnosis of Tinnitus: Neurological Examination
2011
1. There is an urgent need for a set of assessment methods to be agreed upon and utilized by the international tinnitus research community. 2. Neurological examination of tinnitus patients is essential to achieve a good diagnostic approach to the different forms of objective and subjective tinnitus. 3. This chapter summarizes the neurological examination in tinnitus, including the protocol used in the authors’ tinnitus clinic, which is based on the consensus of the Tinnitus Research Initiative (TRI).
