Figure 3.

Anatomic schema displaying the surface anatomy and underlying course of the SSN in a left shoulder. After sterile preparation and draping of the shoulder, the acromion, distal clavicle, and coracoid process are outlined with a marking pen. The portal sites should also be marked (shown in blue) before insufflation because palpable anatomic landmarks can be lost with intraoperative edema. The posterior, midlateral, anterolateral, anterior, Neviaser, and accessory Neviaser portals are marked.
