Ultrasonography-Based Thyroidal and Perithyroidal Anatomy and Its Clinical Significance.

Ha EJ, Baek JH, Lee JH - Korean J Radiol (2015)

Bottom Line: For a safe and effective US-guided procedure, knowledge of neck anatomy, particularly that of the nerves, vessels, and other critical structures, is essential.Therefore, the aim of this article was to elucidate US-based thyroidal and perithyroidal anatomy, as well as its clinical significance in the use of prevention techniques for complications during the US-guided procedures.Knowledge of these areas may be helpful for maximizing the efficacy and minimizing the complications of US-guided procedures for the thyroid and other neck lesions.

ABSTRACT
Ultrasonography (US)-guided procedures such as ethanol ablation, radiofrequency ablation, laser ablation, selective nerve block, and core needle biopsy have been widely applied in the diagnosis and management of thyroid and neck lesions. For a safe and effective US-guided procedure, knowledge of neck anatomy, particularly that of the nerves, vessels, and other critical structures, is essential. However, most previous reports evaluated neck anatomy based on cadavers, computed tomography, or magnetic resonance imaging rather than US. Therefore, the aim of this article was to elucidate US-based thyroidal and perithyroidal anatomy, as well as its clinical significance in the use of prevention techniques for complications during the US-guided procedures. Knowledge of these areas may be helpful for maximizing the efficacy and minimizing the complications of US-guided procedures for the thyroid and other neck lesions.

Transverse ultrasonography images of neck muscles.A-C. Muscles are basic anatomic structures for understanding thyroid and neck anatomies. ASM = anterior scalene muscle, LCo = longus colli muscle, MPSM = middle and posterior scalene muscles, SCM = sternocleidomastoid muscle, SH = sternohyoid muscle, ST = sternothyroid muscle

Figure 15: Transverse ultrasonography images of neck muscles.A-C. Muscles are basic anatomic structures for understanding thyroid and neck anatomies. ASM = anterior scalene muscle, LCo = longus colli muscle, MPSM = middle and posterior scalene muscles, SCM = sternocleidomastoid muscle, SH = sternohyoid muscle, ST = sternothyroid muscle

Mentions: The strap muscles are a group of 4 pairs of muscles in the anterior part of the neck consisting of the thyrohyoid, sternohyoid, omohyoid, and sternothyroid muscles (Fig. 15) (5960). The strap muscles originate from or insert into the hyoid bone, and function to depress the hyoid bone and larynx during swallowing and speech. Because the sternothyroid and thyrohyoid muscles attach to the thyroid cartilage, the thyroid gland moves together during swallowing. The omohyoid muscle consists of superior and inferior bellies. The inferior belly forms a flat, narrow fasciculus at the lower part of the neck, and becomes tendinous behind the SCM muscle (5960). The tendinous portion of the omohyoid muscle can be misdiagnosed as a mass on transverse US; however, it can easily be identified by following the oblique course of the muscle on US.
