Z-shaped skin incision applying Kraissl's lines for an axillary thoracotomy

A Z-shaped skin incision applying Kraissl's lines for a thoracotomy is presented herein. The center of the Z-shape is located on the intercostal space of the thoracotomy. Parallel Z-shaped lines are described on circular Kraissl's lines in the axillary region. The oblique cross-line of the Z-shape is drawn from the dorsal edge of the cranial line to the anterior edge of the caudal line. The angle of the triangular skin flaps is adjusted to 30 degrees or greater in order to keep good microcirculation. The incision gives good exposure for the operative fields and results in a cosmetically satisfactory scar.
