Thyroglossal cysts are fluid-filled sacs formed by residual cells left along the thyroid gland’s embryological migration pathway. Commonly located in the neck region, they are among the most frequently encountered neck masses in childhood. These cysts typically appear in the midline of the front of the neck. Similarly, dermoid cysts are also commonly seen in this area and often present with similar signs and in nearly the same location.

Symptoms

Thyroglossal and dermoid cysts are frequently observed in children and adolescents. They may appear at birth or during early childhood. They are usually diagnosed when symptoms such as neck swelling, pain, inflammation, infection, or discharge develop.

On physical examination, a midline cystic structure is typically noted in the neck. A key clinical sign is that if the cyst moves when the child swallows or protrudes the tongue, it suggests a thyroglossal cyst. If there is no movement, a dermoid cyst is more likely. Ultrasonography can provide a more definitive differential diagnosis.

Treatment

If not treated properly, both types of cysts may progress and cause infection, discharge, swelling, or even breathing difficulties and trouble swallowing.

In cases of infected cysts, antibiotic therapy should be administered first, followed by surgical removal of the cyst a few weeks later.

• If the diagnosis is a dermoid cyst, simple excision of the cyst is sufficient.

• In thyroglossal cysts, however, the tract between the cyst and the base of the tongue must also be completely removed. This procedure is known as the Sistrunk operation.

Although rare, postoperative complications such as infection and recurrence can occur in both conditions. Thyroglossal and dermoid cysts are very likely to be benign and can be effectively managed with appropriate treatment. Early diagnosis and proper surgical intervention reduce the risk of complications and help preserve the overall health and well-being of the child.
