Humans also have an omohyoid
muscle, but little was understood about what it did.
In normal condition [Figure 1]a, omohyoid
muscle (OH) consists of superior and inferior bellies united at an angle by an intermediate tendon (IT) and it passes behind the sternocleidomastoid (SCM) muscle.
Furthermore, RCC was detected in the Delphian nodule and the right jugular vein in the right omohyoid
muscle, which was taken during the neck dissection.
The hyoid myotomy operation involves moving the hyoid bone forward, detaching the muscles (sternohyoid, omohyoid
, thyrohyoid and stylohyoid) and fixating the hyoid bone to the thyroid cartilage with non-resorbable sutures.
Important dynamic stabilizers consist of the sternocleidomastoid, trapezius, strap muscles (sternohyoid, sternothyroid, thyrohyoid, and the omohyoid
), and paraspinal muscles.
These include cutaneous branches of the cervical plexus supplying the skin overlying the posterior triangle; the platysma and omohyoid
muscles; the spinal accessory nerve, which innervates the SCM and trapezius muscles; the deep cervical lymph nodes; the brachial plexus; and numerous arteries and veins--prominent is the external jugular vein (see Figure 2).
muscle lies superficially and the strong reflective signal of the first rib is noted inferiorly.
The majority of the articles describe its posterior insertion on the superior margin of the scapula, near the insertion of the omohyoid
Vocalise patterns that involve bridging out of falsetto into full voice, particularly on /u/, which tends to have a lower laryngeal position, can be very helpful for developing the extrinsic stabilizing muscles (omohyoid
, sternohyoid, sternothyroid).
The strap muscles (Sternohyoid, sternothyroid and superior belly of the omohyoid
) are located anteriorly and are innervated by the ansa cervicalis (Ansa hypoglossi).
Pedicle of supraclavicular artery flap lies in this triangle deep to the belly of the omohyoid
parallel to the clavicle.
(The sternohyoid and omohyoid
muscles can also be dissected; the length of the dissection depends on the distance from the hyoid bone to the area to be reconstructed.) We dissected only enough tissue to allow for the free movement and interposition of the hyoid bone muscle pedicle to the reconstructed area.
