Brief Summary

Oncoplastic breast surgery, combining oncological resection with plastic surgical techniques, has emerged as an important surgical strategy to optimize conventional breast-conserving surgery. The upper inner quadrant is one of the most difficult and challenging tumor locations for surgeons to perform oncoplastic breast surgery. There is a pressing need to develop a simple and effective oncoplastic surgical technique to cope with the unfavorable anatomy and location of tumors in the UIQ. Here, we present a new oncoplastic volume displacement technique for UIQ using the DSG flap. This trial was design to estimate the aesthetic outcomes of an oncoplastic technique using a droplet-shaped glandular flap for breast cancer in the upper inner quadrant.

Oncoplastic technique with a droplet-shaped glandular flap

Intervention Type: PROCEDURE

A droplet-shaped glandular flap (DSG) is in a shape of a water drop, with the pedicle at the top of the defect and the base underlying nipple-areolar complex (NAC). It runs from the outer upper quadrant to the center along a line parallel to the radial line. We harvest a DSG flap by dissociating the supplement mammary gland from the lateral of the defect after resection, developing deep to the pectoralis fascia, from the cusp at the defect and the round pore underlying nipple-areolar complex (NAC). The DSG flap was rotated inwards around the cusp, reaching the top of the defect. This tailored redistribution allowed the defects to be "plugged" with the lateral glandular flaps.
