Incision: Anatomy and Surgical Technique
Considerations • Access to upper outer
quadrant and axillary tail • Sentinel lymph node:
axillary counter-incision vs mastectomy incision
• Dissection technique:
cautery vs tumescent • Reduced traction on flaps • Completion lymph node
dissection required • Positive nipple-areolar
pathology
