Summary
During dissection of the submandibular region of a forty year old male a unilateral left accessory mylohyoid muscle was revealed. This muscle was located between the left anterior belly of the digastric and left mylohyoid muscles. It arose from the left mylohyoid line of the mandible and was inserted into the lower portion of the mylohyoid raphe and hyoid bone. This unilateral accessory mylohyoid muscle is a rare anomaly, which is thought to contribute to the functional support of the floor of the mouth.
Résumé
Au cours de la dissection de la région submandibulaire, un m. mylohyoïdien accessoire gauche a été trouvé chez un homme de 40 ans. Ce muscle é tait situé entre le ventre antŕieur du m. digastrique gauche et le m. mylo-hyoïdien gauche. Il naissait de la ligne mylo-hyoïdienne gauche de la mandibule et s’insérait sur la partie inférieure du raphé mylo-hyoïdien et sur l’os hyoïde. Le m. mylo-hyoïdien accessoire unilatéral est une anomalie rare, qui, nous le pensons, peut participer à la fonction du plancher oral.
