Duct Excision
- The duct can be localized using a lacrimal duct probe or via preoperative ductography.
- If the lesion cannot be localized, a complete subareolar duct excision is indicated. A circumareolar incision is made, and the subareolar area and 2 to 3 cm of breast parenchyma can often be excised.
- If the lesion can be localized, that corresponding duct can be resected. Terminal duct excision is typically performed using a circumareolar incision. Resection is limited to the region of disease to prevent parenchymal disruption or future difficulty with lactation.
