The major horn of the hyoid bone is a useful repair in lateral neck surgeries.
Its highlight allows us to specify the location:
- towards the upper: of the hypoglossal nerve next to the ranine veins and of the lingual artery (in the triangle of Beclard).
- downwards: from the nerve and the superior laryngeal vessels (in the Portmann quadrilateral).
