ABSTRACT
Preop Preoperative lymphoscintigraphy may be necessary if dissection is performed for
melanoma of the trunk and the nodal drainage pattern is ambiguous.
Procedure Step 1. A soft roll is placed longitudinally beneath the shoulder and flank to
displace the axilla anteriorly and allow easier access to the axilla. The arm is placed at slightly less than a 90° angle from the trunk. Care is taken to prevent hyperexten sion of the shoulder by elevating the arm on pillows and then securing it to an arm board in a stationary position.
