Structures in this region commonly assessed by clinicians include the cervical lymph nodes, external jugular vein, brachial plexus, SCM and scalenus muscles.
A moderate decrease in right lateral flexion and right rotation associated with muscular spasms (bilaterally) at the cervical paraspinal and scalenus muscles was present.
It blends with the parietal pleura and is reinforced by the scalenus minimus muscle.

The key points in both the approaches are (1) complete resection of bony, cartilaginous, and fibrous parts of (2) complete resection of the scalenus anterior muscle at the scalene tubercle on the first rib and (3) arterial exploration and reconstruction.
