Observational study on risk factors determining residual dizziness after successful benign paroxysmal positional vertigo treatment: The role of subcl…
2018
Studio osservazionale sui fattori di rischio che causano residual dizziness dopo il trattamento della vertigine parossistica posizionale benigna: il ruolo della VPPB subclinica.Alcuni pazienti, dopo il trattamento della vertigine parossistica posizionale benigna concluso con successo, possono lamentare un disequilibrio residuo. La possibile spiegazione potrebbe essere: la persistenza di otoliti canalari insufficienti a provocare un nistagmo clinicamente evidente, una disfunzione utriculare, coesistenza di altri disordini del sistema vestibolare. Abbiamo condotto uno studio osservazionale prospettico caso-controllo, focalizzando l’attenzione sul ruolo di fattori di rischio che possono causar…
Sudden sensorineural hearing loss associated with inner ear lesions detected by magnetic resonance imaging.
2017
Although recent advances in magnetic resonance imaging (MRI) techniques have contributed to the detection of tiny lesions in the internal auditory canal (IAC) that may be responsible for sudden sensorineural hearing loss (SSNHL), there have been relatively few studies on the clinical characteristics of intra-labyrinthine hemorrhage (ILH) and labyrinthitis versus those regarding IAC tumors. Our purpose was to investigate the frequency of those IAC lesions on MRI and their clinical characteristics. Initial MRIs of 200 patients with SSNHL (93 men, 107 women; mean age = 48.61 years, range: 18-84 years), as well as detailed clinical histories, audiological examinations, and thyroid function, lip…
A multicenter observational study on the role of comorbidities in the recurrent episodes of benign paroxysmal positional vertigo
2014
Objective: Primary objective of this study was to find a statistical link between the most worldwide comorbidities affecting the elderly population (hypertension, diabetes, osteoarthrosis, osteoporosis and depression) and recurrent episodes of BPPV. Secondary objective was defining possible "groups of risk" for people suffering recurrent positional vertigo related to the presence of a well documented comorbidity. Methods: This was an observational, cross-sectional, multicenter, spontaneous, non-pharmacological study. The data of 1092 patients suffering BPPV evaluated in 11 different Departments of Otolaryngology, Otoneurology and Neurology, referring Centers for positional vertigo evaluatio…
Malignant paroxysmal positional vertigo
2011
Objective: An insidious percentage of paroxysmal positional vertigo appears to be intractable with canalith repositioning maneuver and also is not self-limiting. This type of positional vertigo is sustained by the action of intracranial tumors that mimics the clinical aspects of benign paroxysmal positional vertigo.Aim of this study is to clarify the features of these forms of positional vertigo, which we indicate as malignant paroxysmal positional vertigo. Methods: We retrospectively reviewed the clinical records of all the patients who presented with vertigo spells and were managed at our tertiary care referral centre over a three years period. Two hundred and eleven patients with diagnos…
Benign paroxysmal positional vertigo as a complication of osteotome expansion of the maxillary alveolar ridge.
2001
Benign paroxysmal positional vertigo (BPPV) is a common vestibular end organ disorder characterized by short, often recurrent episodes of vertigo that are triggered by certain head movements in the plane of the posterior semicircular canals. BPPV may be idiopathic or secondary to a number of underlying conditions such as head injury, viral labyrinthitis, stapes surgery, and chronic suppurative otitis media. 1,2 The most commonly accepted theory postulates the development of BPPV as a result of canalolithiasis, 3 heavy, inorganic particles detached from the otoconial layer by degeneration or head trauma gravitate into the posterior semicircular canal and act as a plunger on the endolymph and…
Understanding benign paroxysmal positional vertigo: the management of lateral canal involvement
2013
Benign paroxysmal positional vertigo (BPPV) represents the most common cause of peripheral vertigo. The treatment of this apparently intractable disease is actually a physical treatment: performing manoeuvres on the patient to restore the normal condition of the inner ear. However, the following information will help readers who are unfamiliar with BPPV to improve their knowledge of the condition.
Vertigo and multiple sclerosis: aspects of differential diagnosis.
2002
Equilibrium disorders caused by involvement of brainstem and cerebellar structures are common in patients with multiple sclerosis (MS), but peripheral conditions such as benign paroxysmal positional vertigo (BPPV) can be sometimes confused with those of a central origin. Therefore, an accurate otoneurologic investigation paying attention to differential diagnosis aspects should be performed in these subjects. Among available diagnostic tools, electro-oculography, posturography and vestibular evoked myogenic potentials (VEMPs) are especially suited to assess vestibulo-oculomotor and vestibulospinal systems. This paper briefly describes the most recent otoneurologic diagnostic strategies for …
