Incidence of unilateral and bilateral benign paroxysmal positional vertigo when the left and right Dix-Hallpike manoeuvres are positive: a model based on the sense of torsional nystagmus

Patients presenting with nystagmus indicative of benign paroxysmal positional vertigo (BPPV) during the left and the right Dix-Hallpike manoeuvres (DHMs) are frequently seen in clinical practice. In such cases, BPPV may be unilateral or bilateral. The aim of this study is to describe the incidence o...

description Patients presenting with nystagmus indicative of benign paroxysmal positional vertigo (BPPV) during the left and the right Dix-Hallpike manoeuvres (DHMs) are frequently seen in clinical practice. In such cases, BPPV may be unilateral or bilateral. The aim of this study is to describe the incidence of unilateral and bilateral BPPV when both DHMs are positive, taking into account the sense of the torsional component of nystagmus. This is a prospective multicentre study. BPPV patients were classified into three groups: patients with only one positive DHM (control group, CG), patients showing positive bilateral DHM with nystag - mus in the same sense in both DHMs (same sense group, SSG) and patients showing posi - tive bilateral DHM with the torsional component of nystagmus beating in opposite senses in each DHM (opposite sense group, OSG). Only one Epley Manoeuvre (EM) was performed on all patients. Based on the ipsilateral result of the EM, the contralateral result of the same EM and the BPPV resolution rate in the control group, a model was developed to predict the incidence of unilateral and bilateral BPPV in the SSG and the OSG. There were 234 patients in the control group, 20 in the SSG and 23 in the OSG. The model estimated that the percentage of unilateral BPPV would be 89.5% in SSG and 38.7% in OSG. Using these findings, we conclude that when both DHMs are positive, BPPV may be unilateral or bilateral. If the torsional components of both nystagmuses beat in the same sense, it is more likely to be unilateral BPPV. If the torsional components beat in opposite senses, both situations can be considered equally likely.

In questi casi la BPPV può essere unilaterale o bilaterale. Lo scopo del presente studio è quello di descrivere l’incidenza della BPPV uni - laterale e bilaterale, quando entrambe le DHM sono positive, considerando il verso della componente torsionale del nistagmo. In questo studio prospettico multicentrico i pazienti sono stati suddivisi in tre gruppi: pazienti con solo una DHM positiva (gruppo di controllo, CG), pazienti con DHM positiva bilateralmente e con nistagmo battente nello stesso verso evocabile in entrambe le manovre (gruppo stesso verso, SSG), pazienti con DHM positiva bilateralmente e con nistagmo avente componente torsionale con verso opposto nelle due manovre (gruppo verso opposto, OSG). La manovra di Epley (EM) è stata condotta su tutti i pazienti. Considerando i risultati ottenuti dalla EM e il tasso di risoluzione della BPPV nel CG, è stato sviluppato un modello predittivo dell’incidenza della BPPV unilaterale e bilaterale negli SSG e OSG. Il CG comprendeva 234 pazienti, 20 erano inclusi invece nel SSG e 23 nell’OSG. Il modello ha stimato che la percentuale di BPPV unilaterale ammonterebbe a 89,5% nel SSG e 38,7% nel OSG. In conclusione, se entrambe le DHM sono positive, la BPPV può essere sia unilaterale che bilaterale. Se la componente torsionale dei nistagmi batte nello stesso verso, è più probabile che la BPPV sia unilaterale; se invece tale componente ha verso opposto alle DHM, le due condizioni possono considerarsi ugualmente probabili.Pacini EditoreCirugía2020info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://hdl.handle.net/11441/146907https://doi.org/10.14639/0392-100X-2214reponame:idUS.
