[Anatomical variation of the helix root (Radicis Helicis)].
The root of the helix is not a smooth structure and morphologically constant but shows a series of irregularities, which are described in this article. 288 patients were aleatory studied and found some prominences, localized on the root of the helix. There are two tubercules--upper and lower--and one cleft or groove facing the lower branch of the antehelix. We report these variants as well as the prevalences dues to the age and sex.
