The carotid triangle is one of the paired triangles in the anterior triangle of the neck. The triangles of the neck are surgically focussed, first described from early dissection-based anatomical studies which predated cross-sectional anatomical description based on imaging (see deep spaces of the neck).
- superior: posterior belly of digastric
- anteroinferiorly: superior belly of omohyoid
- posterior: sternocleidomastoid
- floor: thyrohyoid, hyoglossus, middle and inferior pharyngeal constrictors
- roof: skin, superficial fascia, platysma, deep fascia
The internal carotid artery initially lies postero-laterally to the external carotid artery. It then becomes posterior to it.
Branches of the external carotid artery are found in the triangle including:
Corresponding veins to these branches drain into the internal jugular vein.
Crossing both the internal and external carotid artery is the hypoglossal nerve.
