Cleidohyoideus Accessorius - an Additional Strap Muscle in the Neck
Öz
Variations of the muscles in the infrahyoid region assume clinical significance during diagnostic and surgical procedures in the region of neck. Accessory muscles are rare anatomical variants which may have clinical implications. The present case reports the existence of an accessory muscle, the cleidohyoid. The muscle was unilaterally observed arising from the upper surface of the middle of the clavicle and inserting into the hyoid bone. The occurrence of this muscle in the densely packed region as in the neck may have functional, diagnostic, surgical and pathological implications.
