A review of nipple-areola complex reconstruction and tattooing techniques.

Breast cancer is the most common malignancy among women, and as survival continues to improve, increasing attention has been placed on optimizing quality of life after treatment. Breast reconstruction is an important part of this process and remains among the top five reconstructive procedures performed in the United States. Reconstruction of the nipple-areola complex (NAC) is often the final-and in many ways the most rewarding-step in the reconstructive sequence. NAC reconstruction plays a critical role in psychological recovery by helping patients regain a sense of wholeness after mastectomy. The objective of this study was to provide an overarching review on NAC reconstruction techniques, drawing from published literature and current institutional practices. A narrative review was conducted by querying PubMed using the terms ("NAC" OR "nipple-areolar complex") AND ("reconstruction" OR "tattoo") to synthesize contemporary literature on NAC reconstruction techniques including local flaps, grafts, implant devices, and tattooing. Additionally, patients who underwent NAC reconstruction at a single academic institution were reviewed and outcomes included. Local flaps are the foundation of surgical NAC reconstruction, though projection loss can vary from 40-75% depending on flap type. Adjuncts such as acellular dermal matrix (ADM), bioabsorbable scaffolds, and implant devices can improve projection durability. Tattooing techniques have advanced substantially able to deliver three dimensional results with a high patient satisfaction and minimal down time; however, pigment fading is common. NAC reconstruction is an individualized process that can be achieved using a variety of tools including flaps, implant devices, and tattooing. These techniques can be used in combination or on their own depending on patient preference and anatomy with the goal of delivering symmetry, durability, and high satisfaction.
