Findings and procedure details
As the neural structures are not visible in CT and aiming to make and anatomical-radiological correlation,
we performed a CT scan of an anatomical piece from the nasal bone to the sternal manubrium.
The piece was later converted into axial sections of about 1,5 cm gross parallel to the hard palate,
in which we identify the neural structures to,
after that,
locate them in the respective CT images (Fig. 16) .
We also compare the cross-section images with the CT images (Figs.
17-27) and cervical ultrasound (Fig. 28) in living subjects.
Ansa cervicalis (anterior or superior branch)
Anatomic reference: the anterior dihedral angle between the internal jugular vein and the common carotid artery,
posterior to the sternocleidomastoid muscle in the upper segments (Fig. 18,
Fig. 20) and posterior to the omohyoid in the lower ones (Fig. 22, Fig. 24).
Vagus nerve
Anatomic reference: Posterior dihedral angle between the internal jugular vein and the common carotid artery,
anterior to the scalene muscles (Fig. 18,
Fig. 20,
Fig. 22, Fig. 24).
Recurrent laryngeal nerve
Anatomic reference: Lateral to the oesophageal wall,
posterior and medial to the lateral lobes of the thyroid gland in the lower segments (Fig. 27) and anterior to the pyriform sinus in the upper segments (Fig. 20).
