Summary
The results of the surgical anterior approach to the cervical spine are marked in a number of cases by dysphagia and dysphonia, especially when the approach is extensive or performed at the upper cervical spine. 35 cadaver dissections were performed to define the topography of the nerve structures during operative exposure at various vertebral levels : superior and recurrent laryngeal nerves, hypoglossal nerve and its superior root of the ansa cervicalis. The authors suggest some technical improvements, for each stage of surgical dissection.
Résumé
Les suites de la chirurgie du rachis cervical par voie antérieure présternocléidomastoïdienne sont marquées dans un nombre de cas non négligeable par des troubles de la déglutition et de la phonation, et ce, d'autant que l'abord est étendu. 35 dissections sur cadavres ont été réalisées afin de préciser la topographie par rapport aux niveaux vertébraux, le trajet et les variations des éléments nerveux rencontrés lors de cet abord cervical : nerfs laryngés supérieur et récurrent, nerf hypoglosse et la racine supérieure de l'anse cervicale. A partir de cette étude morphologique, les auteurs suggèrent quelques points d' amélioration technique, à chacune des étapes de la dissection, en pratique chirurgicale.
