Introduction: The increase in the incidence of breast cancer at a global and national level, presupposes a challenge both for the surgical elimination of breast cancer and for breast reconstruction postmastectomy, as an integral part of the definitive treatment. There is an important group of techniques, within which breast reconstruction with the use of the myocutaneous flap of the Dorsal Ancho muscle is one of the most implemented. Objective: To evaluate the use of the myocutaneous flap of the Dorsal Ancho muscle in postmastectomy mammary reconstruction and definitive prosthesis placement. Material and methods: A retrospective, descriptive and longitudinal study was carried out by the Plastic Surgery Department of the Hermanos Ameijeiras Hospital in the implementation of this surgical procedure, between 2016 to 2018, 22 mastectomized patients were operated on for breast restoration using a Dorsal Ancho myocutaneous flap breast endoprosthesis placement. Results: The 22 postmastectomy patient's predominantly infiltrating ductal carcinoma and they performed the Madden technique mostly. In more than 70% of the cases a skin island of horizontal design was planned on the muscle and complications were scarce except for the seroma in the donor area, which was observed in 63% of the cases. In general in more than 80% of the cases, results were obtained between very good and good. Conclusions: The complication rate was low, with very good results and a high degree of satisfaction of the majority of the patients, which allowed to show the utility of the application of this procedure in postmastectomy breast reconstruction.

Introduction: Surgical removal of modeling substances is the treatment of choice in iatrogenic allogenosis. This is a disease caused by the injection of substances misnamed “biopolymers” with high antigenicity and low histocompatibility. Symptoms can be local or general, leading to a systemic inflammatory autoimmune syndrome induced by adjuvants. Method: A patient operated by open method for the surgical extraction of allogenic substances in the gluteal region is described. Results: A 46-year-old female patient with a history of injection of more than 1000 ml of liquid silicone in both buttocks and face 11 years ago is presented. Two years later, she presented erythema, increased consistency, pruritus, and hyperemia, associated with general symptoms that limited her daily activities. She was diagnosed with an adjuvant-induced systemic inflammatory autoimmune syndrome and was admitted for surgical removal of the causative agent. Surgical extraction of alloplastic material in the gluteal region was performed for the first time in Cuba without local postoperative complications. Conclusion: Surgical treatment by the open biopolymer extraction method is deforming, but it is the only solution to improve the symptoms of iatrogenic allogenosis.

Introduction: The skin and nipple sparing mastectomy is a technique currently on the rise. It arises for the treatment of benign breast lesions; but with the high worldwide incidence of breast cancer, it is used in risk-reducing surgery and breast cancer. In this perspective, numerous technical modifications are described for the minimally invasive surgical approach through low visibility accesses in breast cancer surgery. Objective: To present a technical modification for the Skin-Sparing Modified Radical Mastectomy with preservation of the nipple areola complex and immediate reconstruction with implants by Minimally Invasive Surgery. Methods: We present three patients with left breast cancer operated on for Skin-Sparing Left Modified Radical Mastectomy with preservation of the nipple areola complex and immediate reconstruction with placement of retropectoral implants by minimally invasive surgery through a single periareolar incision. Results: Skin-Sparing Left Modified Radical Mastectomy was performed with preservation of the nipple areola complex and immediate reconstruction with retropectoral prosthesis by minimally invasive surgery in three patients. The evolution was favorable, with good clinical and aesthetic results, without complications and with a high degree of satisfaction according to the international Breast Q scale. Conclusion: Minimally invasive surgery with single periareolar access is safe and effective for Skin-Sparing Radical Mastectomy with preservation of the nipple areola complex, as well as the axilla approach and immediate reconstruction with the placement of retropectoral breast implants.

Introduction: The reconstruction of the breast after mastectomy is included in the treatment of breast cancer and one of the most used techniques is tissue expansion. Objective: To evaluate the use of tissue expansion in postmastectomy breast reconstruction. Material and methods: A descriptive and retrospective study was carried out in the plastic surgery service of Hermanos Ameijeiras Hospital. We included 25 patients from the consultation of oncological deformities of the breast, from January 2016 to August 2018. Tissue expansion consists of expanding the skin and placing a silicone prosthesis. A temporary prosthesis is introduced with a valve, under the muscular plane in a deferred form. In the postoperative period, it will be filled until it reaches the necessary size that allows to place a definitive implant. Results: 96% of women were over 30 years of age, 68% were white and histologically diagnosed with infiltrating ductal carcinoma 60%. 64% were reconstructed before the 2 years after the radical mastectomy and in the healthy breast; reductive mastoplasty was performed to achieve symmetry. Complications were present in 20% of the patients and the results obtained were good in 82.6% of the patients. Conclusions: The use of tissue expanders with endoprotesis in postmastectomy breast reconstruction is a safe and effective technique with a high degree of satisfaction for the majority of patients.

Introduction: The healing is the result of the natural restoration of the organism before a corporal aggression produced by a surgical wound or trauma. Poor wound and injury healing represents a functional and aesthetic problem, which is why it deserves special attention. Objective: To evaluate the aesthetic results of the treatment of pathological scars with lipotransfer by nanofat. Method: A prospective longitudinal and descriptive study was carried out with 8 patients from Plastic Surgery Hospital ‘‘Hermanos Ameijeiras” with pathological scars, who received lipotransfer treatment by Coleman method and processing of adipose tissue by nanofat from January to June 2020. Results: 8 patients with ages between 25 and 50 years with a mean age of 39 years were included. The female sex predominated with 75%. The predominant skin color was grades 3 and 5 of the Fitzpatrick classification, both with 50%. The most frequent etiologies were post acne, postoperative and injection scars of allogenic substances, all with 25%. The main anatomical locations were the facial region and in the breasts with 3 patients each, followed by 2 cases in the gluteal region. The postoperative aesthetic results at three months were 100% good, observing macroscopic and microscopic positive changes with the nanograft. No patient presented complications. Conclusions: The treatment of pathological scars with lipotransfer by nanofat is an available, simple and reproducible option that offers objective improvement of the scar with rapid recovery.
