Strap muscle of neck are dissected.
Reconstructed CT scan of the neck as shown in the picture above demonstrates a midline cystic lesion i.e Thyroglossal duct cyst with a slightly enhancing wall.
In the management of thyroglossal cyst, the central portion of hyoid is excised.
Thyroglossal cyst is managed by Sistrunk operation in which the cyst is completely excised along with the thyroglossal tract. Since the thyroglossal tract is intimately related to the hyoid bone, the central portion of the hyoid bone is also removed.
