Abstract
Thyroid ectopia (TE) is an embryological aberration of the thyroid gland migration most commonly observed in the lingual region followed by the sublingual, hyoid, and mediastinal regions. TE is often complicated by local compressive symptoms resulting in dysphagia, dysphonia, and dyspnea. Surgical removal of TE is frequently complicated by difficulties in intubation, increased perioperative bleeding, and severe primary hypothyroidism; on the other hand, I131 ablation is limited by high doses needed and the concern for long-term effects especially in children. We report three children with TE who all presented with compressive symptoms and were managed conservatively with levothyroxine resulting in resolution of compressive symptoms and favorable outcomes. Levothyroxine supplementation is effective and has an important role in managing TE, not only in correcting the associated hypothyroidism but also in resolving the associated compressive symptoms by reducing the size of the ectopic thyroid tissue.
