Endoscopic Thyroidectomy via Breast Approach for Patients with Graves’ Disease

Background Endoscopic thyroidectomy via breast approach provides excellent results from a cosmetic viewpoint. We applied this procedure to Graves’ disease and evaluated its feasibility and outcomes. Methods From May 2006 to November 2009, a total of 37 patients (34 women and 3 men) with Graves’ disease were included in this study. Bilateral subtotal thyroidectomy, which left behind 4–6 g of thyroid remnant, was the standard procedure. For markedly enlarged goiter, fractional resection was performed. Results This procedure was performed successfully in all 37 patients. The mean operative time, mean blood loss, and mean excised thyroid weight were 84.7 min, 64 ml, and 51.8 g, respectively. Fractional resection was performed in six cases, where the mean operative time, mean blood loss, and mean excised thyroid weight were 119 min, 138.3 ml, and 102.2 g, respectively. Postoperative transient hypocalcemia occurred in 5 cases (13.5%), and no other complications were noted. The average postoperative hospital stay was 3.4 (range, 3–5) days. One case experienced recurrent hyperthyroidism during a mean follow-up period of 13 months. All patients were satisfied with the cosmetic result of the procedure. Conclusions Endoscopic subtotal thyroidectomy performed via breast approach is a technically feasible and safe procedure with excellent cosmetic results for patients with Graves’ disease. In patients with markedly enlarged thyroid glands, subtotal thyroidectomy can be achieved through a fractional resection strategy.
