Endoscopic total thyroidectomy.

BACKGROUND AND

OBJECTIVE

Endoscopic neck surgery for the thyroid and parathyroid is being tested as an alternative to open thyroidectomy. The aim of this study was to determine the safety and feasibility of endoscopic transaxillary total thyroidectomy (ETTT).

METHODS AND

RESULTS

Twenty-two consecutive patients from January 2006 to September 2008 underwent ETTT. No conversions to open were necessary. Mean age was 49.3+/-12.9 years, 20 were female, and 2 were male. Mean operating time was 238 minutes+/-72.7. Mean blood loss was 40mL+/-28.3mL. Mean weight of the gland was 137.05g+/-129.21g. The recurrent laryngeal nerve was identified with no permanent injury. Six patients developed hoarseness of the voice for a mean of 15.1+/-8.01 days. No patient developed tetany or hypocalcemia requiring treatment. Six patients experienced transient numbness in the anterior chest wall lasting 2 weeks in 5 patients and 2 months in one. All patients were discharged within 24 hours of admission.

CONCLUSION

ETTT requires additional operative time compared with the open approach, but is cosmetically favorable. Visualization of the nerve and parathyroid is much better. Although the learning curve is steep, with experience the operative time will decrease. ETTT is different but safe and feasible.
