What is the effect of vestibular neuritis on postural control?
Benign paroxysmal positional vertigo (BPPV) of the anterior canal is rare. The rarity of this clinical form is probably due to anatomical reasons (common growth of the anterior and posterior canals, and verticality of the anterior canal). It may also be due to a lack of consideration and clinical elucidation.
The acute and isolated vertiginous symptoms, heterogeneous in their presentation, are a frequent reason for consultation in the emergency room and are a source of diagnostic errors.
Three main aetiologies are involved: positional vertigo, vestibular neuritis and more rarely posterior fossa stroke.
A well-conducted clinical examination, including the nystagmoscopic examination, the head impulse test and the cover test has high diagnostic sensitivity. The diffusion sequence MRI is essential, but its sensitivity remains low in the first hours, especially in small infarcts.
Orofacial dyspraxias are defi ned by dysfunctions, deviation, or even hypersol licitation of the orofacial sphere. They are closely related to postural abnormalities. They mainly include anomalies of ventilation, swallowing, phonation, mas tication, bruxism and other parafunctions.
