The need for Class I and II studies on the efficacy of Semont’s liberatory maneuver (SLM) in the treatment of posterior canal benign paroxysmal positional vertigo (PC-BPPV) motivated the present double-blind randomized trial on the short-term efficacy of SLM. A total of 342 patients with unilateral PC-BPPV were recruited for a multicenter study. Patients(More)
The aim of this study is to verify the hypothesis that free-floating particles could sometimes localize into the distal portion of the non ampullary arm of the posterior semicircular canal (PSC) so that assuming the Dix-Hallpike's positions, the clot could move towards the ampulla eliciting a inhibitory torsional-down beating paroxysmal positional nystagmus(More)
OBJECTIVES/HYPOTHESIS The need for class I and II studies on the efficacy of liberatory maneuvers in the treatment of lateral canal benign paroxysmal positional vertigo (LC-BPPV) motivated the present double-blind randomized trial on the short-term efficacy of the Gufoni liberatory maneuver (GLM). STUDY DESIGN Double-blind randomized controlled trial. (More)
We lately reported the cases of patients complaining positional vertigo whose nystagmic pattern was that of a peripheral torsional vertical positional down beating nystagmus originating from a lithiasis of the non-ampullary arm of the posterior semicircular canal (PSC). We considered this particular pathological picture the apogeotropic variant of PSC(More)
Epidermoid cysts are rare congenital tumors of the central nervous system (CNS), histologically benign and slow-growing lesions. Their frequency among primitive intracranial tumors is about 1% and they account for 40% of all in-tracranial epidermoid of the cerebellopontine angle (CPA); there they constitute the third most frequent neoplasm (5%), after(More)
