When deciding the treatment of lingual thyroid, the fact that more than 70% of lingual thyroid cases have no orthotopic thyroid tissue should be kept in mind. That is to say, removal of lingual thyroid may cause hypothyroid function.
In this brief paper, a case of lingual thyroid that was treated successfully by transposition is reported. The patient was a 6 year old female and complained of dysphagia that had increased recently. The ectopic thyroid feeding artery was not demonstrated preoperatively. One side of the intrinsic and extrinsic muscles of the tongue was conserved as much as possible, and a pedicled flap was made. Lingual thyroid was included at the terminal segment of the flap, and transposed inferior to the right submandibular area. Postoperatively, thyroid function was retained and the mass of the base of the tongue disappeared.
This technique is widely indicated for the conservative surgery of lingual thyroid.
