Interpectoral approach to dissection of the axillary apex: an elegant and effective approach.

BACKGROUND

Axillary dissection is the gold standard for treatment of the axilla. It provides important prognostic information, accurately stages the axilla, and has the lowest recurrence rate among all modalities. In today's age of conservation surgery, the axilla is often addressed through a cosmetically acceptable small incision with limited access, thereby making clearance of the level III nodes difficult.

METHODS

We describe a method of apical lymph node dissection through the interpectoral plane, which effectively clears the apex despite the constraints of limited exposure.

RESULTS

This method has been used in nearly 5,000 axillary dissections performed at our institute, with excellent results. It preserves the innervation of the pectoral muscles and affords access to the interpectoral nodes.

CONCLUSIONS

Our method has a short learning curve, provides good exposure of a difficult area and consistently provides a good yield of nodes.
