Accessory Clavicular Head of Sternocleidomastoid Muscle: A Case Report
نویسنده
چکیده
A unilateral (Left side) additional Clavicular head of sternocleidomastoid (SCM) was found during routine dissection of head and neck region in 43 years old male cadaver. The additional slip was extended its origin almost whole the length of middle third of clavicle. The fusion failure or abnormal mesodermal splitting during development may be the reason for present variation at origin of sternocleidomastoid. The internal jugular can be approached at the lesser supra clavicular fossa for cannulation during central venous access, temporary haemodialysis, and the placement of inferior vena cava filters. The anatomical knowledge of the SCM and its variations is identical significant for surgeons during branchial cyst removal, while dealing with myocutaneous flap.

The sternocleidomastoid, a prominent landmark of neck, offers protection to the major blood vessels and the nerves of this region. In recent era, this muscle has received a great attention of oncologists, general surgeons and plastic surgeons as it can be used as an excellent myocutaneous flap in reconstructive surgeries of head and neck region. The sternocleidomastoid is the key muscle of the ...

Introduction The sternocleidomastoid (SCM) which is shortly called as sternomastoid extends obliquely across the side of the neck and divides the neck into anterior and posterior triangle. The SCM occupies key position since a host of important structures of neck like great vessels and branches of cervical plexus are overlapped by the muscle [1]. It takes origin by two heads (sternal and clavic...

Morphological variations of the sternocleidomastoid (SCM) muscle assume relevance during attempted surgical interventions in the cervical region. The present study reports bipartite clavicular attachment of the SCM in the neck of an adult male cadaver during performance of a routine anatomy demonstration. The anomaly was unilaterally observed on the left side of the neck. The clavicular head of...

The sternocleidomastoid muscle (SCM) functions as a landmark for physicians such as anatomists, orthopaedic surgeons, neurosurgeons, and anaesthesiologists, who intervene in the minor supraclavicular fossa located at the base of the neck. The variability of SCM anatomy may cause complications while trying to access the vital elements that are located in the minor supraclavicular fossa. This stu...

A rare case of unilateral third head of sternocleidomastoid and an extra muscle – levator claviculae were determined unilaterally in a 70-year-old male cadaver during the routine dissections. In the left neck side, it was observed that the sternocleidomastoid muscle also had a third part in addition to known sternal and clavicular heads and levator claviculae muscle which arose from the posteri...
