The Case of Asymmetry of the Omohyoid Muscle

The asymmetry of omohyoid muscles was found during topographic anatomical preparation of female cadaver (using methods: anatomical preparation and morphometry) which was use in medical student’s training. The detected deviations in structure of this muscle, accordingly to many articles, have not only anatomic value but also a significant importance for clinical surgeons of different fields. The described anatomical variation of omohyoid muscle structure (the asymmetry) has some very important clinical aspects, concerning front neck region surgery. Omohyoid muscle is a reliable landmark for endoscopic examination of brachial plexus and searching for metastases in neck lymphatic nodes. In some cases, hypertrophy of omohyoid muscle can cause development of functional dysphagia and spastic torticollis.
