Single Biaxillary Tunneling for Working Space Creation in Bilateral Axillo-Breast Approach (BABA) Thyroidectomy.

BACKGROUND: Endoscopic thyroidectomy using the bilateral axillo-breast approach (BABA) achieves excellent cosmetic results. However, concerns have been raised about the extensive dissection and violation of the breast during working space preparation.

MATERIALS AND METHODS: We developed a "single biaxillary tunneling" technique for working space creation in BABA thyroidectomy; this technique was applied in 30 cases.

RESULTS: Skin bruise was hardly visible, and only minor and small bruises were observed. The whole process of working space creation typically finished within 20 to 30 minutes.

CONCLUSIONS: Limited blunt dissection by a single stroke of biaxillary tunneling is a simple method, which significantly reduces ecchymosis formation and is time-efficient. This method can be used in routine practice and is feasible for beginner surgeons.
