Check out this video on the omohyoid muscle one of the infrahyoid muscles of the neck.
. Locating and studying the omohyoid muscle was technically challenging. Take a closer look at the omohyoid muscle in our atlas. CT showed an isodense enlargement of the left omohyoid muscle with the greatest dimension of 16 cm.
The omohyoid is a paired flat strap of muscle that is made up of superior and inferior bellies joined by an intermediate tendon. Anuj Bhatia MBBS MD FRCA FFPMRCA FIPP FRCPC EDRA CIPS Philip Peng MBBS FRCPC Founder Pain Med in Essentials of Pain. The deep cervical fascia which usually envelopes the omohyoid muscle may be weakened by stress as 20 of cases had a preceding traumatic event.
The purpose of this study is to explore the anatomical relationship between the omohyoid muscle and the internal jugular vein on ultrasound guidance and. Open or endoscopic transection of the muscle and ultrasound-guided botulinum toxin injection were 3 treatment options with no recurrence at 4 years 6 months and 6 months respectively. Anaplastic thyroid cancer is an uncommon entity that is usually seen in older patients.
However the omohyoid muscle which is adjacent to the internal jugular vein is a rarely mentioned muscle of the infrahyoid muscles group. The sternothyroid sternohyoid thyrohyoid and omohyoid muscles. Ultrasoundguided injection of botulinum toxin in a patient with omohyoid muscle syndrome.
This technique can also be utilized for injection of botulinum toxin into the omohyoid muscle. PDF Background Internal jugular vein catheterization is widely used in clinical practice and there are many related studies on internal jugular vein. It is a group of four pairs of muscles in the anterior part of the neck.
The strap muscles are arranged in a superficial layer sternohyoid and omohyoid muscles and a deep layer sternothyroid and thyrohyoid. The common carotid artery 6 the sternocleidomastoid muscle 8 the omohyoid muscle 9 the long muscle of the neck 12 the scalene muscles 14 and the vertebral artery 15. The omohyoid muscle is located slightly lateral and deep to the clavicular head of the sternocleidomastoid muscle approximately ¾ to 1 inch above the superior margin of the clavicle.
Musculoskeletal Ultrasound Scan of Long Axis of Omohyoid Muscle from insertion on Scapula to its origin by Dr Stanley Lam. Studies on internal jugular vein catheterization. We present a case of omohyoid muscle syndrome diagnosed based on the clinical presentation and a dynamic imaging study.
It surrounds the front and sides of the visceral space and posteriorly it is related to the carotid space. They run closely together from the lateral neck toward the scapular notch. On ultrasound a hypoechoic ovoid smooth bordered lesion is seen at the level of the hyoid bone and slightly right off midline left image.
However the omohyoid muscle which is adjacent to the internal jugular vein is a rarely mentioned muscle of the infrahyoid muscles group. In addition the omohyoid muscle is easily ignored in a clinical setting. In addition to medication treatment for omohyoid syndrome includes stretching ice heat and ultrasound therapy.
Real-time ultrasonography establishes the diagnosis demonstrating the anterolateral displacement of the sternocleidomastoid muscle by a thickened omohyoid muscle during swallowing. Sternohyoid sternothyroid and thyrohyoid. C Ultrasound image of the sub-omohyoid plane showing the inferior belly of the omohyoid muscle omohyoid and the adjoining suprascapular nerve arrow seen just lateral to the brachial plexus BP.
Ultrasound-Guided Procedures for Pain Management. A case report PoHsien Su MD Department of Physical Medicine and Rehabilitation National Taiwan University Hospital 7 ChanShan South Road 100 Taipei Taiwan ROC. They are all attached to the hyoid bone and look like a strap.
The literature reports that in the clinical setting omohyoid. Physical therapy including heat ice ultrasound and. The target for the injection is marked by the arrowhead and is a fascial plane.
MRI showed a 5 2 4 cm ovoid mass T1 isointense to muscle and T2 very slightly hyperintense to muscle embedded within the left strap. The omohyoid muscle is an infrahyoid muscle of the neck that is innervated by the ansa cervicalis of the cervical plexus receiving fibers from the ventral rami of C1C3 spinal nerves. Omohyoid muscle syndrome has a characteristic feature of a protruding lateral neck mass during swallowing.
Ultrasound-guided fine-needle aspiration and core needle biopsy revealed benign skeletal muscle. The function of this muscle is to depress the hyoid bone and larynx and reestablish breathing following the act of swallowing. The primary function of the omohyoid muscle is to.
The pectoralis major PMaj muscle is seen superficially. The omohyoid muscle is a thin long muscle located on both sides of the neck. Find read and cite all the research.
The suprascapular nerve SSN courses deep and parallel to the omohyoid muscle OM from its origin off the upper trunk of the brachial plexus in the lateral cervical region to its passage through the suprascapular foramen Standring 2008The OM muscle begins as a superior belly originating from the hyoid bone narrowing to a central. The omohyoid muscle is a key to finding the suprascapular nerve when it is hard to find. The purpose of this study is to explore the anatomical relationship between the omohyoid muscle and the internal jugular vein on ultrasound guidance and provide a theoretical reference for jugular puncture.
The geniohyoid muscle inserts on to the anterior and upper surface of the body of the hyoid bone. The paired geniohyoid muscles lie adjacent to one another and are immediately superior to the mylohyoid muscle s on the floor of the mouth and inferior to the genioglossus muscles that form the roof of the mouth. MRI scans of the neck can look for injury to the muscle and to exclude other causes such as tumors.
Omohyoid is a paired muscle located in the anterior region of the neck. Ultrasound may demonstrate a large poorly circumscribed neck mass with involvement of the trachea strap muscles or lateral neck vessels Fig. The Omohyoid Syndrome is usually caused by trauma such as whiplash or by excessive vomiting.
Treatment is conservative and includes non-steroidal anti-inflammatories and muscle relaxants. The anterior cervical space is located deep to the sternocleidomastoid muscle and infrahyoid muscles. The deep cervical fascia which usually envelopes the omohyoid muscle may be weakened by stress as 20 of cases had a preceding traumatic event.
For example early ultrasound-guided technology was rarely used in internal jugular vein catherization. It belongs to a group of muscles called infrahyoid muscles along with three others.
