Cleido-Occipital Platysma Muscle: An Uncommon Variation of the Sternocleidomastoid

The Cleido-Occipital Platysma Muscle (COPM) is a rare anatomical variant characterized by an additional slip of muscle fibers that extends from the sternocleidomastoid muscle to the occipital bone. This abstract explores the anatomy and clinical significance of COPM, shedding light on its potential impact on neck movement, surgical procedures, radiological interpretation, and its role in causing pain and discomfort. This rare anatomical variant underscores the complexity of human anatomy and the need for healthcare professionals to recognize its presence for safe and effective medical practice. Further research may provide valuable insights into the prevalence and functional aspects of this intriguing anomaly.
