Neck Spaces

But don t worry these triangles are not hard to remember and they are very important for understanding neck anatomy.

Neck spaces. The neck spaces are often divided into the suprahyoid between the base of the skull and hyoid bone and infrahyoid between the hyoid bone and clavicles spaces as the anatomy of the deep cervical fascia is slightly different above and below the hyoid bone. These spaces are present in the neck between the layers of cervical fascia. These spaces are important from the point of view of clinician because of the propensity of infections to involve this space and to spread along these spaces to involve other areas like the mediastinum.

Arrangement of superficial and deep layers of cervical fascia the importance of this spaces is that they may limit to some degree the spread of most infections and some tumors a proper understanding of their anatomy will also aid in the diagnosis of various conditions. Intr0duction basis for dividing neck into spaces and compartments. The neck triangles are actually spaces bordered by the neck muscles.

Retropharyngeal space between visceral division of middle layer and alar division of deep layer extend from skull base to t2 level more common in children due to presence of retropharyngeal node. This space predominantly contains fat and can be easily identified arrows in b and c on both ct hypodense on ct and mr bright on t1 weighted sequences images. Space involving entire length of neck 1.

Many of these spaces could as well be inconsequential. You may be shocked that we re mentioning triangles here as you probably didn t enroll in anatomy because you love maths. Axial graphic a ct b and t1 weighted mr c images show the normal anatomy of the parapharyngeal space pps.
