Subtotal thyroidectomy with transposition of the remnant gland to the subcutaneous space. A new alternative technique in benign thyroid disease.

BACKGROUND

Thyroidectomy is the preferred surgical option for the treatment of benign disease of the thyroid in a wide rage of indications. Controversy exists concerning the extent of the primary excision for optimal results. A subtotal thyroidectomy with transposition of the thyroid remnant to the subcutaneous space prevents thyroid hormone supplementation for life and laryngeal nerve damage during a re-operation.

METHODS

We present the case of a 42-year-old female with nontoxic multinodular goitre who underwent subtotal thyroidectomy in which a thyroid remnant of the left upper pole was placed subcutaneously through a buttonhole incision at the junction of the left sternocleidomastoid and the pre-thyroidal muscles. The remnant of thyroid nourished by the vascular pedicle of the superior pole vessels was sutured to the pre-thyroidal muscles.

RESULTS

One month after operation, the remnant was palpated as a small well-limited mass without signs of inflammation and thyroid function tests were normal. A contrast-enhanced computed tomography (CT) scan confirmed the subcutaneous position of the thyroid tissue without pathological signs. The scintigraphy showed uptake radioactivity by the transported thyroid remnant. One year after operation the patient was clinically euthyroid with TSH and T4 levels within normal limits.

CONCLUSIONS

This report documents the feasibility and efficacy of subtotal thyroidectomy with transposition of the thyroid remnant to the subcutaneous space in multinodular goitre.
