[The vallecula: an anatomic reality?].

The vallecula epiglottica is a borderline area between the pharynx and the larynx, though covered by the epiglottis, and a functionally strategic site and breeding ground for epidermoid carcinoma, but it has remained unappreciated by anatomists. The borders of the vallecula within the oropharynx are represented by the anchoring systems of the epiglottic cartilage; the basilingual margin is sometimes inaccurate. We would like to emphasize the topographical relationships in the vallecular region, in particular: --the proximity to the base of the tongue, which is the preferred are of extension of epitheliomas, --and the features of the hyoepiglottic membrane, which is a veritable barrier for neoplastic infiltration. The valleculae epiglotticae are a definite oropharyngeal anatomical entity, and deserve the attention of maxillofacial surgeons, who should be able to suggest a surgical treatment of cancers that would be practicable both from a functional and from an oncological point of view.
