The infrahyoid neck muscles are four strap-like, paired muscles that are situated in the anterior compartment of the neck below the hyoid bone. These include:Sternohyoid muscleOmohyoid muscleSternothyroid muscleThyrohyoid muscleLevator glandulae thyroideae muscleThese are mainly innervated by branches from the ansa cervicalis. This risks denervation of the mus- cles but avoids a difficult dissection freeing the strap muscles from the previous operative bed. from publication: Deep Neck Space infections in Of note is that the strap muscles themselves can be mistaken for hypertrophied thymic tissue at CT because of their similar densities (Fig. Because of their appearance, they are also known as strap muscles. Infrahyoid muscles The infrahyoid muscles of mammals are a group of strap-like muscles in the ventral aspect of the neck with a rather complex pattern of innervation. They can be divided into two groups: Superficial plane – omohyoid and sternohyoid muscles. They act mainly to depress the hyoid bone and larynx during swallowing and speech. The arterial supply to the infrahyoid muscles is via the superior and inferior thyroid arteries, with venous drainage via the corresponding Levator Scapulae Muscle Subglottic Space Longus Colli and Capitus Muscles Infrahyoid Strap Muscles Trachea Anterior Jugular Vein Anterior Scalene Muscle The infrahyoid muscles (a. Deep plane – sternothyroid and thyrohyoid muscles. The 2 most common complications of TDC are infection and malignancy, the latter of which occurs in 1-4% of cases. A nuclear thyroid scan demonstrated radioactive iodine uptake in both of these extrathyroidal masses confirming multiple sites of ectopic thyroid tissue.

Muscle activity was observed at various pitches during the glissandos. They are responsible for depressing the hyoid during swallowing. 3 cm mass embedded in the left strap muscle without adenopathy. Most of these muscles are attached to the inferior aspect of the hyoid bone, except for the sternothyroid, which connects the sternum with the thyroid cartilage. These muscles can be remembered b Dec 7, 2009 · The CT section is at the level of the supraglottic larynx and the thyroid cartilage. The infrahyoid muscles, or strap muscles, are a group of four pairs of muscles in the anterior (frontal) part of the neck. Thyroglossal duct cyst and branchial cleft cyst. Therefore, complementary sonography or comparison with prior CT is sometimes needed for precise delineation of a hyperplastic thymus. a Axial contrast-enhanced CT image shows a pathology proven thyroglossal duct cyst located anterior to the carotid vessels (arrowheads) and anteromedially to the sternocleidomastoid muscle (asterisks) with a tail-like extension medially to the hyoid bone (arrow).

[1] The four infrahyoid muscles are the sternohyoid, sternothyroid, thyrohyoid and omohyoid muscles. The strap muscle activity during the production of glissandos appears to be synergistic. Thyroglossal duct cyst (TDC) is usually diagnosed clinically, but ultrasonography is the preferred imaging technique in children. [1] Excluding the sternothyroid, the infrahyoid muscles either originate from or insert on to the hyoid bone. CT scan demonstrated the nodular thyroid gland, a 1. At the lowest frequency, the CT is inactive but strap muscles (TH, ST, SH) are active. Occasionally, division of the strap muscles, particularly in surgery for recurrent parathyroid or thyroid disease, can be avoided by a vertical split lateral to the sternohyoid. Ultrasonography showed a unilocular cystic mass and a normal-appearing thyroid gland. b Axial contrast-enhanced CT Radiopaedia’s mission is to create the best radiology reference the world has ever seen and to make it available for free, for ever, for all. Radiopaedia’s mission is to create the best radiology reference the world has ever seen and to make it available for free, for ever, for all. Computed tomography (CT) of the neck demonstrated a cystic structure below the strap muscles ( figure 2). They are all connected to the hyoid and depress the hyoid bone and larynx during swallowing and speaking. aaijy5, 2dgb, dfulb, yqhhz, ntcu5, cghxw, d57lfo, 3lzqq, s7r3dt, hpizu,
