Transaxillary endoscopic breast augmentation is a method of breast augmentation in which breast implants are inserted through an incision in the armpit. The incision is small, about an inch long, and can be easily hidden under the armpit. Once the incision heals, it is barely visible. The transaxillary endoscopic breast approach allows breast implants to be placed under or over the pectoral muscle with great precision. The endoscope is a long, thin tube with a camera on the end that is used to help form the breast implant pocket and place the implant correctly.
