Cervical Soft Tissues

The cervical soft tissues show normal configuration, and the cervical spine is normally positioned.

The oral floor muscles are bilaterally symmetrical and normally developed. The spaces of the oral floor and neck are clear and well defined.

Imaged portions of the parotid and submandibular glands show no abnormalities.

The pharynx and larynx show normal boundaries and normal wall thickness.

The thyroid gland shows reasonable symmetry and normal size. The thyroid lobes have a normal internal structure. Cervical vessels that can be evaluated with CT have a normal appearance.

The muscular structures of the neck appear normal, and there are no signs of cervical lymphadenopathy.
