Inferior and Medially Based Breast Parenchymal Rotation Flap: A New Mastopexy Technique for Replacing Breast Volume After Breast Implant Explantation.

[BACKGROUND] Recently, a growing number of patients have been opting for the removal of breast implants. This often results in a degree of volume loss that can vary from mild to substantial, contingent on the size of the implant, with many patients requiring a mastopexy. Although autoaugmentation mastopexy serves as the primary surgical approach to restore shape and fill the void left by the implant, the fullness attained with the implant cannot be replicated through autoaugmentation.

[OBJECTIVES] Our goal was to present the technical details and utilization of an inferomedial pedicle-based breast parenchymal flap, without rotational restriction from the parenchyma, for autoaugmentation after explantation.

[METHODS] A retrospective chart review was performed of 12 patients who underwent surgery with this technique between the years of 2019 to 2022, with emphasis on reasons for explantation, early and late complications, and satisfaction scores on a Likert scale.

[RESULTS] Capsular contracture was the most common reason for explantation, and only 2 patients experienced minor wound dehiscence in the early postoperative period. With a mean follow-up of nearly 2 years, no bottoming out was encountered in any of the patients, and satisfactory breast shape was obtained. Further, postoperative satisfaction was significantly higher than preoperative satisfaction.

[CONCLUSIONS] The inferomedial-based parenchymal rotation flap is a new procedure that can be applied in this patient group because of its wide rotation arc and reliable vascularity. It is also an effective option for creating the desired conical breast shape in patients who do not want breast implants over the long term.
