Anatomy
[ edit ]
One carotid sheath is situated on each side of the neck,[3] [4] : 266 [2] [4] : 266 [4] : 266
Superiorly, the carotid sheath encircles the margins of the carotid canal and jugular foramen .[2]
Inferiorly, it terminates at the arch of the aorta ;[2] axillary sheath at the venous angle .[3] sternum inferiorly (varying between the levels of C7 and T4 ).[citation needed
Structure
[ edit ]
The carotid sheath is a fibrous connective tissue formation surrounding several important structures of the neck.[2] [2] [1] : 578
The three major fascial layers in the neck contribute to the carotid sheath: the investing fascia , the pretracheal fascia , and the prevertebral fascia . The carotid sheath has limited loose connective tissue .[5]
Contents
[ edit ]
Structures contained within the carotid sheath include the:
Relations
[ edit ]
The carotid sheath occurs at the level of the oropharynx .[3]
The cervical sympathetic trunk is situated posteriormedial to the carotid sheath.[2] : 551
The carotid sheath is situated at each lateral boundary of the retropharyngeal space ,[3] sternocleidomastoid muscle .[2] : 579 [3] [2]
The pharynx is situated medial to the carotid sheath, (in the suprahyoid region) the parotid gland laterally to it, in the suprahyoid region the infratemporal fossa anterior to it, and the prevertebral fascia posterior to it.[2]
Function
[ edit ]
The carotid sheath acts to protect and separate the structures contained within.[2]
Clinical significance
[ edit ]
The carotid sheath may act as a conduit for infections , although this is rare due to the limited connective tissue .[5]
