The infrahyoid muscles , or strap muscles , are a group of four pairs of muscles in the anterior frontal part of the neck. Excluding the sternothyroid, the infrahyoid muscles either originate from or insert on to the hyoid bone. The term infrahyoid refers to the region below the hyoid bone , while the term strap muscles refers to the long and flat muscle shapes which resembles a strap. The stylopharyngeus muscle is considered by many to be one of the strap muscles, [ citation needed ] but is not an infrahyoid muscle. The origin , insertion and innervation of the individual muscles: [3]. All of the infrahyoid muscles are innervated by the ansa cervicalis from the cervical plexus C1 - C3 [4] [5] except the thyrohyoid muscle, which is innervated by fibers only from the first cervical spinal nerve travelling with the hypoglossal nerve.

The infrahyoid muscles or strap muscles are a group of four paired muscles in the anterior neck below the hyoid bone , within the muscular triangle. They are responsible for depressing the hyoid during swallowing. These muscles can be remembered by the mnemonic "TOSS". The strap muscles are ensheathed by the middle layer of the deep cervical fascia , thereby forming one of the deep fascial compartments of the neck , although it is not commonly recognized as such 4. Each muscle is supplied by different nerves from the ansa cervicalis. Sternohyoid receives supply from branches of the superior thyroid artery. Thyrohyoid, omohyoid and sternothyroid receive supply from branches of the superior thyroid and lingual arteries 5. The name "strap muscles" comes from their long and flat shape, similar to a belt or strap 3. The muscles are retracted apart in the midline to access the thyroid gland for thyroidectomy.

Wide and adequate exposure of the surgical field is essential for successful thyroid surgery. The most common procedure for conventional open thyroidectomy is the midline approach, in which the strap muscles are divided along the linea alba and separated from the thyroid gland. An insufficient surgical field exposure not only increases operation time and blood loss, it also increases the risk of injury to the recurrent laryngeal nerve RLN and parathyroid gland PG due to poor visibility during surgical dissection 1. The aim of this study was to evaluate the U-shaped strap muscle flap USMF approach that provides excellent exposure of the surgical field. Postoperative objective voice analysis and subjective assessment of voice and swallowing were also performed to evaluate USMF outcomes, including voice and swallowing function.

Insights into Imaging volume 7 , pages 77—86 Cite this article. Metrics details. Thyroid nodules are a common occurrence in the general population, and these incidental thyroid nodules are often referred for ultrasound US evaluation. US provides a safe and fast method of examination. However, given the financial burden on the health service and unnecessary anxiety for patients, it is unrealistic to biopsy every thyroid nodule to confirm diagnosis. In this pictorial review, we provide a complete series of sonographic images to illustrate benign and malignant features of thyroid nodules according to the U1—5 classification.

The sternothyroid muscle is a wide muscle, located underneath the sternohyoid in the deep plane of the neck. These muscles and other important muscles of note in the thyroid region are:. It also tenses the skin of the neck during clenching of the jaw, often seen when making facial expressions of anger. Epub Feb 1. CA Cancer J. The omohyoid also has a function in ensuring proper venous blood return through its attachment to the carotid sheath. Blood Supply and Lymphatics The thyroid region has an extensive blood supply. They can be divided into two groups:. Contact Us. All authors reviewed the manuscript.
