Nipple-Areola Complex Ischemia or Necrosis in Freestyle Perforator Flap Reduction Mammoplasty Operations.

[BACKGROUND] Necrosis of the nipple-areolar complex (NAC) is one of the most devastating complications of reduction mammoplasty. A variable, asymmetrical pattern of blood supply from the main sources was found in the same individual. To solve this problem, we present a method to be sure that the blood supply to the NAC is contained within the designed pedicle during reduction mammoplasty. This is done using the colored duplex scan and handheld Doppler to perform freestyle perforator flap reduction mammoplasty.

[METHODS] This is a prospective randomized study that has been performed on 105 patients in the period between January 2014 and 2019 at the Plastic and Reconstructive Surgery Department, Tanta University Hospitals. Freestyle perforator flaps were performed for all cases after perforator detection using handheld Doppler and confirmed by colored duplex scan.

[RESULTS] The procedure was performed as freestyle on medial perforators in 35 (33.3%) cases, on lateral perforators in 20 (19%) cases, on combined medial and lateral perforators, as a bipedicle in 30 (28.7%) cases, on upper pole perforators in 12 (11.4%) cases, and on lower pole perforators in 8 (7.6%) cases.

[CONCLUSIONS] The use of handheld Doppler and the confirmation by duplex scan are mandatory to decrease the incidence of NAC necrosis or ischemia.
