[Case report: ipsilateral association of posterior and anterior canalolithiasis].

Benign paroxysmal positional vertigo (BPPV) is the most frequently occurring dizzy syndrome. The literature provides ample descriptions of the forms determined by canalo/cupulolithiasis of the posterior canal, the most common, as well as canalo/cupulolithiasis of the horizontal canal. Descriptions of the forms of canalo/cupulolithiasis of the anterior canal are, instead, very rare and, sometimes questioned: this is fundamentally due to its superior position, which makes it a much less likely site for the accumulation of debris, both from a conceptual and practical point of view. For these reasons, the Authors feel that the presentation of this case of PPV is of particular interest. After analyzing and excluding other interpretations as less probable, they considered the syndrome as determined by the association of right posterior and anterior canalolithiasis. This form, as in the case of posterior canalolithiasis, responded to treatment with Semont's liberatory procedure.
