Summary
The peripheral, extraparotid course and localisation of the marginal mandibular branch of the facial n. is described, with variations, based on the dissection of 40 cadaver half heads. Its anatomical relationships with the ramus of mandible and facial a. are studied and morphometric features are reported. Knowledge of the accurate course and relationship of the marginal mandibular branch should help to protect this nerve from surgical injury.
Réumé
Sur la base de la dissection de 40 hémi-têtes, le trajet distal extra-parotidien et la situation du rameau marginal de la mandibule du nerf facial sont décrits. Les rapports anatomiques entre ce rameau et l'artère faciale sont étudiés et les aspects morphologiques décrits. La connaissance du trajet précis et des rapports du rameau marginal de la mandibule est utile pour la protection de ce nerf au cours des interventions chirurgicales.
