Summary

The aim of this study was to provide some specific information about the morphology and topography of the superior laryngeal n., its branches, and its anastomoses with the cervical sympathetic chain, as well as its relations with the thyroid gland. Sixty adult cadavers, ie 120 superior laryngeal nn., were dissected and analysed. An anastomotic loop connecting the cervical sympathetic chain and the distal laryngeal n. was present in 111 of the 120 cases. The morphology of this loop made it possible to define 5 different groups. This study supplies information valuable in thyroid surgery.

Résumé

Le but de ce travail était d'apporter des précisions sur la morphologie et la topographie du nerf laryngé supérieur de sa branche de division et de ses anastomoses avec la chaîne sympathique cervicale, ainsi que sur les rapports avec la glande thyroïde. 60 cadavres adultes, soit 120 nerfs laryngés supérieurs, ont été disséqués et analysés. Une anse anastomotique unissant la chaîne sympathique cervicale et le nerf laryngé extrême existait 111 fois sur 120. La morphologie de cette anse a permis de définir 5 groupes différents. Ce travail apporte des informations précieuses pour la chirurgie thyroïdienne.
