We present a case of omohyoid muscle syndrome diagnosed based on the clinical presentation and a dynamic imaging study.

. Omohyoid muscle syndrome has a characteristic feature of a protruding lateral neck mass during swallowing. The aim of this study was to obtain normative ultrasonography US data on the suprascapular nerve SSN and omohyoid muscle OM in the lateral cervical region. The anterior cervical space is located deep to the sternocleidomastoid muscle and infrahyoid muscles.

However the omohyoid muscle which is adjacent to the internal jugular vein is a rarely mentioned muscle of the infrahyoid muscles group. 2 also showed the lateral movement of the omohyoid muscle with tenting phenomenon to the adjacent sternocleidomastoid muscle utilizing dynamic computed tomography during swallowing.

They run closely together from the lateral neck toward the scapular notch. 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. 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.

The geniohyoid muscle inserts on to the anterior and upper surface of the body of the hyoid bone. It surrounds the front and sides of the visceral space and posteriorly it is related to the carotid space. A case report PoHsien Su MD Department of Physical Medicine and Rehabilitation National Taiwan University Hospital 7 ChanShan South Road 100 Taipei Taiwan ROC.

However the omohyoid muscle which is adjacent to the internal jugular vein is a rarely mentioned muscle of the infrahyoid muscles group. 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 Omohyoid Syndrome is usually caused by trauma such as whiplash or by excessive vomiting.

Ultrasoundguided injection of botulinum toxin in a patient with omohyoid muscle syndrome. Musculoskeletal Ultrasound Scan of Long Axis of Omohyoid Muscle from insertion on Scapula to its origin by Dr Stanley Lam. The pectoralis major PMaj muscle is seen superficially.

Anatomical relationship between the omohyoid muscle and the internal jugular vein on ultrasound guidance inproceedingsXiong2022AnatomicalRB titleAnatomical relationship between the omohyoid muscle and the internal jugular vein on ultrasound guidance authorZhao-Zhao Xiong year2022.

Treatment is conservative and includes non-steroidal anti-inflammatories and muscle relaxants. The deep cervical fascia which usually envelopes the omohyoid muscle may be weakened by stress as 20 of cases had a preceding traumatic event. Omohyoid m uscle syndrome is a rare clinical condition.

The target for the injection is marked by the arrowhead and is a fascial plane. In addition the omohyoid muscle is easily ignored in a clinical setting. Ultrasound-Guided Procedures for Pain Management.

Physical therapy including heat ice ultrasound and. This technique can also be utilized for injection of botulinum toxin into the omohyoid muscle. MRI scans of the neck can look for injury to the muscle and to exclude other causes such as tumors.

The purpose of this study is to explore the anatomical relationship between the omohyoid muscle and the internal jugular vein on ultrasound guidance and. Real-time ultrasonography establishes the diagnosis demonstrating the anterolateral displacement of the sternocleidomastoid muscle by a thickened omohyoid muscle during swallowing. 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.

Besides real time ultrasound Kim et al. The literature reports that in the clinical setting omohyoid. Locating and studying the omohyoid muscle was technically challenging.

For example early ultrasound-guided technology was rarely used in internal jugular vein catherization. Of the left omohyoid muscle as well as anterolateral gliding of the overlying sternocleidomastoid muscle during swallowing. 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 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. Ultrasound guidance may improve the accuracy of needle. Studies on internal jugular vein catheterization.

That shows unmistakable signs of an X-shaped lateral. PDF Background Internal jugular vein catheterization is widely used in clinical practice and there are many related studies on internal jugular vein. Sternocleidomastoid muscle superficially due.

The strap muscles are arranged in a superficial layer sternohyoid and omohyoid muscles and a deep layer sternothyroid and thyrohyoid. The SSN and OM are known to be related throughout the nerves course yet little imaging data exists on these structures at areas more proximal than the suprascapular foramen.
