“…This finding is in agreement with the researched literature, which affirms that BPPV is one of the most frequent diseases of the vestibular system and prevalent among women, and with other studies that point out women as more susceptible than men to neurotological changes. This "sensibility" may be considered in part as a consequence of the natural hormonal variance common to women [2][3][4]23 .…”

“…BPPV is one of the most common causes of dizziness and its main symptom is the feeling of spinning dizziness caused by the change in the position of the head 21 .In the United States, between 17 and 42% of the patients with vertigo are diagnosed with BPPV and, although this disorder affects people throughout their lifetime, it has the tendency to affect people between 50 and 70 years old, having, therefore, attention called to it in terms of social security and health assistance 2,3 .…”

“…The diagnosis of BPPV of the posterior semicircular canal includes careful attention to the history of vertigo associated with changes in the position of the head, confirmed by the Dix-Halpike maneuver 3 . The operational procedure was carried out with anamnesis by trained evaluators, followed by the Dix-Hallpike maneuver, being considered a case of BPPV every patient that presented one or two-sided nystagmus.…”

OBJETIVO:verificar a prevalência da vertigem posicional paroxística benigna e identificar suas prováveis associações em uma população de idosos.MÉTODOS:estudo transversal realizado em idosos, submetidos à avaliação audiológica, questionário e à Manobra de Dix-Hallpilke. Aplicaram-se os testes não paramétricos: Qui-quadrado e regressão multivariada com intervalo de confiança de 95%.RESULTADOS:a amostra final foi de 494 indivíduos, com mediana de idade de 69(64,75- 74,00) anos. Observou-se a prevalência de 23,9% de vertigem posicional paroxística benigna e 51,6% de dor cervical e 37,9% de cefaléia. Houve associação estatisticamente significante entre a vertigem posicional paroxística benigna e dor cervical, gênero e cefaléia nesta população.CONCLUSÃO:conclui-se que nesta população de idosos a prevalência da vertigem posicional paroxística benigna foi de 23,9% e da dor cervical foi de 51,6% e houve associação significante entre a vertigem posicional paroxística benigna com a dor cervical e com o gênero feminino.

“…For example, repositioning treatment of BPPV involves rotation in the plane of the affected canal in order to exert inertial forces upon the otoconia crystals within the SCC so as to move them from the SCC into the vestibule (Bhattacharyya et al 2008). Otoconial movement is determined by the component of the force that is tangential to the SCC.…”

We report a precise, simple, and accessible method of mathematically measuring and modeling the threedimensional (3D) geometry of semicircular canals (SCCs) in living humans. Knowledge of this geometry helps understand the development and physiology of SCC stimulation. We developed a framework of robust techniques that automatically and accurately reconstruct SCC geometry from computed tomography (CT) images and are directly validated using micro-CT as ground truth. This framework measures the 3D centroid paths of the bony SCCs allowing direct comparison and analysis between ears within and between subjects. An average set of SCC morphology is calculated from 34 human ears, within which other geometrical attributes such as nonplanarity, radius of curvature, and inter-SCC angle are examined, with a focus on physiological implications. These measurements have also been used to critically evaluate plane fitting techniques that reconcile many of the discrepancies in current SCC plane studies. Finally, we mathematically model SCC geometry using Fourier series equations. This work has the potential to reinterpret physiology and pathophysiology in terms of real individual 3D morphology.
