Nipple-areola-complex preservation and obesity-Successful in stages. Microsurgery 2023
The superiority of nipple-sparing mastectomy (NSM) on breast aesthetics and patient-reported outcomes has previously been demonstrated. Despite 42.4% of adults in the United States being considered obese, obesity has been considered a contraindication to NSM due to concerns for nipple areolar complex (NAC) malposition or ischemic complications. This report investigates the feasibility and safety of a staged surgical approach to NSM with immediate microsurgical breast reconstruction in the high-risk obese population.Only patients with a body mass index (BMI) of >30 kg/m2 who underwent bilateral mastopexy or breast reduction for correction of ptosis or macromastia (stage 1), respectively, followed by bilateral prophylactic NSM with immediate microsurgical breast reconstruction with free abdominal flaps (stage 2) were included in the analysis. Patient demographics and surgical outcomes were analyzed.Fifteen patients with high-risk genetic mutations for breast cancer with a mean age and BMI of 41.3 years and 35.0 kg/m2 , respectively, underwent bilateral staged NSM with immediate microsurgical breast reconstruction (30 breast reconstructions). At a mean follow-up of 15.7 months, complications were encountered following stage 2 only and included mastectomy skin necrosis (5 breasts [16.7%]), NAC necrosis (2 breasts [6.7%]), and abdominal seroma (1 patient [6.7%]) all of which were considered minor and neither required surgical intervention nor admission.Implementation of a staged approach permits NAC preservation in obese patients who present for prophylactic mastectomy and immediate microsurgical reconstruction.

Lymphatic Microsurgical Preventive Healing Approach (LYMPHA) for Lymphedema Prevention after Axillary Lymph Node Dissection-A Single Institution Experience and Feasibility of Technique. Journal of clinical medicine 2021; 11 (1)
While surgical options exist to treat lymphedema after axillary lymph node dissection (ALND), the lymphatic microsurgical preventive healing approach (LYMPHA) has been introduced as a preventive measure performed during the primary surgery, thus avoiding the morbidity associated with lymphedema. Here, we highlight details of our operative technique and review postoperative outcomes. For our patients, limb measurements and body composition analyses were performed pre- and postoperatively. Intraoperatively, axillary reverse lymphatic mapping was performed with indocyanine green (ICG) and lymphazurin. SPY-PHI imaging was used to visualize the ICG uptake into axillary lymphatics. Cut lymphatics from excised nodes were preserved for lymphaticovenous anastomosis (LVA). At the completion of the microanastomosis, ICG was visualized draining from the lymphatic through the recipient vein. A retrospective review identified nineteen patients who underwent complete or partial mastectomy with ALND and subsequent LYMPHA over 19 months. The number of LVAs performed per patient ranged between 1-4 per axilla. The operating time ranged from 32-95 min. There were no surgical complications, and thus far one patient developed mild lymphedema with an average follow up of 10 months. At the clinic follow up, ICG and SPY angiography were used to confirm intact lymphatic conduits with an uptake of ICG across the axilla. This study supports LYMPHA as a feasible and effective method for lymphedema prevention.

A Review of Anatomy, Physiology, and Benign Pathology of the Nipple ANNALS OF SURGICAL ONCOLOGY 2015; 22 (10): 3236-3240
The nipple and areola are pigmented areas of modified skin that connect with the underlying gland of the breast via ducts. The fairly common congenital anomalies of the nipple include inversion, clefts, and supernumerary nipples. The anatomy of the nipple areolar complex is discussed as a foundation to review anatomical variants, and the physiologic development of the nipple, including changes in puberty and pregnancy, as well as the basis of normal physiologic discharge, are addressed. Skin conditions affecting the nipple include eczema, which, while similar to eczema occurring elsewhere on the body, poses unique aspects in terms of diagnosis and treatment. This article concludes with discussion on the benign abnormalities that develop within the nipple, including intraductal papilloma and nipple adenoma.
