Summary
The authors of the present study were able to expose the tractus angularis (the mandibulo-stylohyoid ligament), which was consistently found as a large ligament extending from the angle of the mandible to the stylohyoid ligament, with prolongations in the direction of the stylohyoid m. and the posterior belly of the digastric. The ligament forms part of the structures which separate the submandibular gland from the parotid gland. We believe that this ligament should be included in anatomy textbooks, and we affirm our perception of these structures as potentially important for clinical and surgical anatomy.
Résumé
Les auteurs ont mis en évidence un ligament mandibulostylo-hyoïdien (tractus angularis) retrouvé de façon constante comme une dépendance et un prolongement de l'aponévrose cervicale. C'est un ligament large, tendu entre l'angle de la mandibule et le ligament stylo-hyoïdien avec des prolongements vers le m. stylo-hyoïdien et le ventre postérieur du digastrique. Ce ligament fait partie des structures qui séparent les loges de la glande sous-maxillaire de la glande parotide. Nous proposons que ce ligament figure dorénavant dans les ouvrages anatomiques, en rappelant l'importance de cette structure pour l'anatomie clinique, ainsi que pour l'anatomie chirurgicale.
