Langer's axillary arch

Abstract

Langer's axillary arch is usually asymptomatic and difficult to detect preoperatively. When present, it is important for surgeons operating in the axillary region, to identify correctly the relevant anatomy. Simple surgical division is curative and necessary in order to achieve exposure of the axillary contents, lymphatic dissection, and neurovascular preservation.

Keywords: Axilla; Langer's arch; axillary arch; axillary dissection; sentinel lymph node.
