After two sets of Kirschner wires were inserted transversely in the subcutaneous tissue of the anterior neck, the wires were lifted up and fixed to an L-shaped prop (Mizuho, Tokyo, Japan) to yield a working space (Figure 3).
Operative view. Parathyroid adenoma appeared adjacent to the left lower pole of the thyroid gland (arrow).
