Breast Implant Reconstruction in the Ptotic Patient: Evaluation of Wise and Vertical Skin Sparing Mastectomy

Abstract

Introduction: Post-mastectomy reconstruction in patients with severe breast ptosis can be challenging. Traditionally, a skin sparing mastectomy (SSM) with a circumareolar incision or a horizontal elliptical extension results in a long, horizontally-oriented scar in the central breast. The Wise pattern SSM with an inferiorly-based dermal flap addresses skin redundancy and provides added vascularized implant coverage in ptotic patients with macromastia. The purpose of this study is to compare outcomes in ptotic patients undergoing SSM with Wise pattern and a modified vertical technique which also uses de-epithelialized excess skin under the incision. Methods: A retrospective chart review was performed on patients that underwent SSM using a Wise or vertical skin reducing technique. The Wise pattern was performed using an inferiorly-based dermal flap and the vertical method used a laterally-based dermal flap covering the implant/tissue expander (TE). Results: SSM with the use of autoderm was performed in 42 patients (67 breasts) using either the Wise (n = 49 breasts) or vertical (n = 18 breasts) method. Both groups had similar BMI (35.4). The prepectoral plane was used in 93.5% of Wise pattern patients and all vertical patients. All cases of seroma and hematoma occurred in the Wise pattern group (10.2%). Mastectomy skin necrosis requiring unplanned return to surgery for debridement occurred in 20.4% of those undergoing Wise pattern SSM and 11.1% undergoing the vertical pattern (p = 0.49). Conclusion: Severely ptotic patients undergoing SSM have a high risk of skin necrosis. A dermal flap under the closure has the advantage of vascularized tissue reinforcing the wound in implant based reconstruction. The vertical pattern SSM using a laterally-based dermal flap may be a safe, simple alternative to the Wise pattern in select patients.
