Abstract:-Background: The omohyoid muscle is one of the infrahyoid muscles of the neck. It has superior and inferior bellies and an intermediate tendon. Variations in the omohyoid muscle are quite rare. Main observations: We report a case where the superior belly of the omohyoid muscle was absent. Its inferior belly originated from the upper border of scapula near suprascapular notch and passed across the posterior triangle, behind the sternocleidomastoid muscle. The muscle then blended with the fascia of the sternocleidomastoid muscle on its posterior surface. It was supplied by the ansa cervicalis. Due to the absence of the superior belly, division of the anterior triangle of the neck was incomplete. Conclusions: The omohyoid is important in radical neck dissections because it is the surgical landmark for level III and IV lymph node metastases. Thus, knowledge of anomalies of this muscle is important to minimize the complications during the surgical procedures of the cervical region.
Keywords:-Infrahyoid muscles, omohyoid muscle, absence of superior belly. |
