ABSTRACT

Postoperative sensitivity of the nipple-areola complex (NAC) is an important concern for women after reduction mammoplasty. Previous studies have demonstrated that sensory branches of the fifth anterior intercostal nerve are important for innervating the NAC and that using an inferior pedicle technique is associated with improved sensory retention. The significance of this case report is that it demonstrates the importance of the fifth anterior intercostal sensory nerve branches using a prototype fluorescent imaging camera. The benefit of this device is that it can detect intraoperative auto-fluorescence of nerves and facilitate their identification and preservation, potentially facilitating the retention of sensation in the NAC and surrounding skin. The goals of this article are, therefore, to demonstrate the importance of this neurovascular pedicle when the inferior pedicle technique is used for breast reduction; and to provide demonstrative evidence of the nerve's presence within the fifth anterior intercostal artery perforator pedicle. The case involved a woman with mammary hypertrophy who underwent bilateral reduction mammoplasty using the inferior pedicle technique. Full NAC sensation was demonstrated on postoperative day 3 with complete sensory recovery at 1- and 3-month follow-up confirmed. To our knowledge, this is the first reported instance of the fifth intercostal nerve being visualized during aesthetic breast surgery, demonstrating the importance of this neurovascular bundle for sensory preservation when an inferior pedicle reduction mammaplasty technique is used.

ABSTRACT

RESUMEN Antecedentes: la reconstrucción mamaria inmediata prepectoral con implantes es la incorporación técnica más reciente al arsenal de reconstrucción mamaria. Esta técnica proporciona un aspecto más natural a la reconstrucción, elimina complicaciones, como la deformidad por animación, y disminuye el dolor posoperatorio. Objetivo: describir los resultados quirúrgicos en una serie de pacientes con reconstrucción mamaria inmediata prepectoral con implantes de silicona. Material y métodos: se realizó un estudio retrospectivo descriptivo; fueron revisadas las historias clínicas y los informes de anatomía patológica de pacientes operadas con la técnica descripta entre marzo de 2018 y diciembre de 2021, por carcinoma invasor, no invasor y sarcoma de mama. Todas fueron evaluadas en el preoperatorio con mamografía digital y presentaban más de 2 cm de cobertura grasa en la mama intervenida. Resultados: se registraron 52 reconstrucciones en 40 pacientes. El promedio de edad fue de 52 años (rango 30-76). En todas se realizó mastectomía con preservación del complejo aréolapezón. Con un promedio de seguimiento de 40 meses, no se registraron complicaciones mayores. No se encontró animación, desplazamiento ni rotación del implante. Se observó contractura capsular grados III y IV después del año de seguimiento en 3 pacientes que realizaron radioterapia posoperatoria. Los resultados estéticos fueron excelentes y buenos en 40 mamas (80,0%), regulares en 8 mamas (12,0%) e insuficientes en 4 mamas (8,0%). Se necesitó revisión quirúrgica posoperatoria inmediata por hematoma en 4 mamas (7,7%). Conclusiones: la reconstrucción inmediata con implantes prepectorales posmastectomía fue una técnica segura y con alto porcentaje de satisfacción.


ABSTRACT Background: Prepectoral implant-based breast reconstruction has recently been added to the armamentarium for breast reconstruction. This technique provides natural-looking breasts, avoids complications, such as animation deformity, and reduces postoperative pain. Objective: The aim of this study was to describe the surgical outcomes in a series of patients undergoing immediate prepectoral breast reconstruction with silicone implants. Material and methods: A descriptive and retrospective study was carried out with review of the medical records and pathology reports of patients who underwent surgery using the described technique for invasive carcinoma, non-invasive carcinoma, and sarcoma of the breast from March 2018 to December 2021. All the patients were evaluated preoperatively with digital mammography and had fat coverage thickness in the operated breast > 2 cm. Results: A total of 52 reconstructions were performed on 40 patients. Mean age was 52 age (range 30- 76). The nipple sparing mastectomy was undertaken in all the cases. There were no major complications during the 40-month average follow-up. None of the patients experienced animation deformity, implant displacement, or rotation. After one year of follow-up, three patients who underwent postmastectomy radiotherapy showed grades III and IV capsular contracture. The aesthetic results were excellent and good in 40 breasts (80.0%), fair in 8 breasts (12.0%) and insufficient in 4 breasts (8.0%). Four breasts (7.7%) required surgical revision in the immediate postoperative period. Conclusions: Immediate prepectoral implant-based breast reconstruction is a feasible technique with enduring results and high level of satisfaction.

ABSTRACT

BACKGROUND: There are differing opinions with regard to the specific mechanical forces related to contraction of the frontalis muscle and how it exerts its effects on eyebrow motion. OBJECTIVES: To perform a detailed anatomic and clinical study of the frontalis muscle in cadavers and patients to better define the movement of the frontalis muscle. METHODS: This study consisted of four arms that included: 1) dynamic ecography to evaluate movement of the frontalis muscle, 2) anatomical study of the relationship between the frontalis muscle and the deep fascia, 3) histological study to define the frontalis muscle attachments and 4) clinical study to evaluate the action of the frontalis muscle in patients undergoing a temporal face lift. RESULTS: The frontalis muscle was attached, inserted, and adhered to the deep layer of the fascia in the superior cephalic and middle third of the forehead. In the superior cephalic third of the forehead, loose areolar tissue was observed deep to the frontalis muscle and the deep layer of the fascia. Within the middle third of the forehead, the deep layer of the galea was fused with the periosteum and firmly adhered. In the inferior caudal third of the forehead, the frontalis muscle was separated from the deep galeal aponeurosis and interdigitated with the orbicularis muscle. When the frontal muscle end was dissected free from the deep fascia by approximately 1 cm and pulled upward, no movement of the eyebrows was observed. Eyebrow elevation was only achieved by pulling on the inferior part of the muscle. CONCLUSIONS: Frontalis muscle movement occurs from the inferior caudal end towards the mid part of the muscle as it contracts centripetally on its superficial layer sliding over the deep part strongly attached to the deep fascia.

ABSTRACT

BACKGROUND: The central inframammary incisional approach for breast augmentation surgery disrupts the fifth anterior intercostal nerve-artery-vein-plexus. The authors hypothesized that preservation of the fifth anterior intercostal neurovascular pedicle might completely preserve nipple-areola complex (NAC) sensitivity after implant breast augmentation. OBJECTIVES: The aim of the study was to analyze if the use of a laterally displaced incision achieves better sensitivity results than the conventional median submammary incision in females who underwent primary breast augmentation surgery. METHODS: A group of 25 female patients (50 breasts) underwent a surgical protocol for primary prepectoral implant breast augmentation with a laterally displaced submammary incision. This group was compared to a similar group of 25 patients (50 breasts) who underwent breast augmentation through a conventional submammary central approach. Sensitivity testing with Semmes-Weinstein monofilaments was performed in both groups preoperatively and on postoperative days 2, 14, and 30, and after 6 months. RESULTS: Both groups were similar in age, BMI, comorbidities, and implant volumes. Preoperatively, all patients reported normal sensory function in both breasts. Postoperatively, in the laterally displaced incision group, sensory function remained normal in NAC areas, whereas in the conventional incision group, all cases presented the same degree of sensitivity diminution at Days 2, 14, and 30 (P = .000). At 6 months, all values were the same as at Day 30. CONCLUSIONS: Preservation of the fifth AIC pedicle resulted in complete preservation of preoperative NAC sensitivity. The laterally placed inframammary incision should be considered for patients undergoing primary prepectoral implant breast augmentation.

ABSTRACT

The use of nipple-sparing mastectomies has increased steadily over the past 10-15 years. However, one major source of patient dissatisfaction with both skin- and nipple-sparing mastectomies is lost skin and/or nipple sensation postoperatively due to intraoperative, iatrogenic sensory nerve injury. We summarize the case of a 41-year-old woman with BRCA(+) breast cancer who underwent bilateral, risk-reducing nipple-sparing mastectomies, immediately followed by bilateral, direct-to-implant breast reconstruction, in whom a prototype fluorescent imaging camera was used to facilitate sensory nerve identification and preservation. Preoperatively, tactile and thermal quantitative sensory testing were performed using a 30-gauge needle to determine baseline sensory function over both breasts. Then, nipple-sparing mastectomies and direct-to-implant reconstruction were performed. Using a laterally-displaced submammary approach, the anterior intercostal artery perforator neurovascular pedicle was preserved. Then a prototype camera, which emits near-ultraviolet light, was used to detect nerve autofluorescence. Intraoperatively under near-ultraviolet light, both the fifth intercostal nerve and its sensory branches auto-fluoresced clearly, so that surgery was completed without apparent injury to the fifth intercostal nerve or any of its branches. Postoperatively, the patient reported full sensory function throughout both breasts and both nipple-areolar complexes, which was confirmed on both tactile and thermal sensory testing at 3-month follow-up. The patient experienced no complications and rated her overall satisfaction with surgery on both breasts as 10 out of 10. To our knowledge, this is the first time sensory nerve auto-fluorescence has been reported to reduce the likelihood of intraoperative, iatrogenic nerve injury and preserve sensory function.

ABSTRACT

INTRODUCTION: The traditional donor sites for autologous breast reconstruction include the abdomen, thigh, buttock, and posterior thorax. Herein, we describe the use of the reverse lateral intercostal perforator (LICAP) flap originating from the submammary region as an option for breast reconstruction. METHODS: Fifteen patients (30 breasts) were included in this retrospective review. The procedure was performed for immediate reconstruction following a nipple sparing mastectomy utilizing an inframammary incision or an inverted T pattern with preservation of the fifth anterior intercostal perforator (n = 8), volume replacement after implant explantation (n = 5), and partial lower pole resurfacing with exteriorization of a portion of the LICAP skin paddle (n = 2). RESULTS: Flap survival was achieved in all patients. Three flaps (10%) had 1-2 cm of intraoperative distal tip ischemia, which was managed by excision prior to inset and closure. At the 12-month postoperative follow-up, stable results with good nipple position, breast shape, and projection were achieved in all patients. CONCLUSIONS: The reverse LICAP flap is a safe, effective, and reliable option for breast reconstruction following mastectomy.

ABSTRACT

BACKGROUND: The traditional design for truncal perforator flaps is ipsilateral without midline decussation. The presumed rationale is to minimize the risk of distal flap necrosis. In this article, the authors present their experience and results with contralateral truncal perforator flaps designed and raised crossing the midline. METHODS: This retrospective analysis included 43 patients (25 men and 18 women) who underwent reconstructive surgery from 1984 to 2021 using a contralateral flap design crossing the midline in the anterior trunk and upper back. Considerations included pathology, location, and the dimensions of the defect and flap. Arithmetic and weighted means with their 95% confidence intervals were estimated to compare ipsilateral and contralateral techniques. RESULTS: Contralateral flaps used included the internal mammary perforator flap ( n = 28) superficial superior epigastric artery flap ( n = 8), superior epigastric perforator flap ( n = 2), and the second or ninth dorsal intercostal artery perforator flap ( n = 5). All of these flaps, excluding the superficial superior epigastric artery flap, demonstrated length and coverage surface averages that were significantly greater than those of traditional ipsilateral flaps. However, with the contralateral superficial superior epigastric artery, both measures were statistically similar to those of traditional ipsilateral flaps. CONCLUSION: The anatomical variation design suggests that the trunk midline is not a barrier and that perforator flaps in these two regions may be raised on different longitudinal axes without compromising vitality. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

ABSTRACT

Introduction: Malignant primary lymphoma represents only 1%-5% of all gastric tumours. Spontaneous gastric perforation in the absence of chemotherapy in these cases is extremely rare. The vast majority of primary gastric lymphomas have a B-cell phenotype that originates from mucosa-associated lymphoid tissue and primary gastric lymphomas with a T-cell phenotype are rarely reported. This report describes a case of a primary gastric T-cell malignant lymphoma associated to spontaneous perforation and peritonitis. Case presentation: An 80-year-old woman referring 24 hours of abdominal pain associated to cognitive impairment consulted to our Emergency Department. Her past medical history revealed smoking, hypothyroidism, dilated cardiomyopathy, hypertension, celiac disease with poor adherence to gluten-free diet and a Non-Hodgkin T cell lymphoma associated to enteropathy in 2010. At physical examination, she presented with tachycardia, hypotension and abdominal tenderness. Lab test revealed low red cell count and an abdomen computed tomography scan showed pneumoperitoneum secondary to a large gastric perforation located in the anterior wall of the antrum. Urgent surgery was performed. At exploratory laparoscopy, a 5 cm perforation of the anterior wall of prepyloric antrum was observed associated to a 4-quadrant peritonitis. Conversion to open surgery was decided to perform an open antrectomy and Billroth II gastro-jejunostomy. The patient was transferred to ICU after surgery under mechanical respiratory assistance for closed monitoring but evolved with a cardiogenic shock and deceased on the first postoperative day. The final histopathological and immunohistochemical analysis reported enteropathy-associated T-cell lymphoma of gastric localisation with concomitant celiac disease. Discussion: We present a rare case of a patient with a history of celiac disease who developed a gastric perforation secondary to an enteropathy-associated T-cell lymphoma of gastric localisation. To the best of authors' knowledge, there have been reported less than 30 cases of spontaneous perforation of gastric lymphoma in the absence of chemotherapy in the last 35 years. Malignant gastric lymphoma, accounting only for 1% of primary gastric malignancies, is usually a diffuse large B-cell lymphoma. Incidence of perforation of gastric lymphomas in patients receiving chemotherapy rounds 0.9%-1.1%. However, it is a rare condition in patients not receiving chemotherapy. Conclusion: This is a rare case of a patient with an enteropathy-associated T-cell lymphoma of gastric localisation, who developed a spontaneous gastric perforation in the absence of chemotherapy. Despite it is a rare condition, it must be suspected in patients with a history of lymphoma in the context of acute abdominal pain.

ABSTRACT

BACKGROUND: Preoperative vascular mapping has been demonstrated to be an excellent adjunct to perforator flap surgery by reducing operative times and enhancing surgical precision. This study evaluated the benefit of preoperative vascular mapping using magnetic resonance imaging and Doppler ultrasonography to identify the different perforators to the breast and compared it to postoperative mapping. The authors' intent was to determine whether preoperative knowledge of the various vascular sources to the nipple-areola complex affected the outcome and vitality of the nipple-areola complex. METHODS: A prospective study was performed on 15 patients undergoing 25 nipple-sparing mastectomies for breast cancer or genetic predisposition. Ten patients underwent bilateral mastectomy, and five underwent unilateral mastectomy. Mean age was 52 years (range, 30 to 76 years). The mean patient body mass index was 22.4 kg/m2 (range, 20 to 35 kg/m2). Inclusion criteria consisted of breast cancer or genetic predisposition and grade 1 or 2 breast ptosis. Exclusion criteria included prior breast surgery, grade 3 ptosis, and gigantomastia. All patients underwent immediate direct-to-implant reconstruction. RESULTS: Preoperative vascular mapping by magnetic resonance imaging and external Doppler ultrasonography was performed in all 15 patients. In all 25 breasts, the fifth anterior intercostal artery perforator was identified preoperatively and preserved intraoperatively. Postoperative imaging demonstrated patency of the fifth anterior intercostal artery perforator vessels in all patients. Nipple-areola viability was demonstrated in all breasts. CONCLUSIONS: This study demonstrates that preoperative magnetic resonance imaging and Doppler ultrasonography for mapping breast perforator vessels is a useful strategy and should be considered for select patients undergoing nipple-sparing mastectomy. Identification of dominant perforators to the breast allowed mastectomy planning with preservation of the important perforator to the mastectomy skin flaps and nipple-areola complex. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

ABSTRACT

INTRODUCTION: Achieving breast symmetry following unilateral mastectomy remains a challenge. Contralateral procedures are usually necessary to achieve breast symmetry. Controversy exists regarding whether these symmetry procedures should be performed at the time of the initial reconstruction or on a delayed basis. MATERIALS AND METHODS: The study included 105 patients who had unilateral mastectomy, of which 55 had a simultaneous (immediate) contralateral symmetry procedure and 50 had a delayed contralateral symmetry procedure. Outcomes were compared and assessed for each cohort based on demographics, complications, and patient satisfaction. RESULTS: The delayed cohort required more procedures (3.4 vs. 1.8, p < 0.0001) but shorter overall hospitalization length (2.8 vs. 4.1 days, p < 0.0001). The two cohorts experienced a similar rate of revision (38.3% vs. 49.3%, p = 0.17) The delayed cohort required a contralateral balancing procedure after completion of reconstruction more often than the immediate cohort (p = 0.021). Overall reconstruction-specific complication rates were similar in both cohorts. The 36-Item Short-Form Health Survey (SF-36), a validated questionnaire for quality-of-life assessment, was administered 3 months after surgery and demonstrated that both cohorts reported similar outcomes when comparing their satisfaction with treatment. CONCLUSIONS: The results of this study demonstrate that immediate contralateral symmetry operations can be performed safely without increased morbidity. A new algorithm is presented.

ABSTRACT

BACKGROUND: The authors describe the vascular anatomy of the fifth anterior intercostal artery perforator and its role for perfusion of the nipple-areola complex following nipple-sparing mastectomy. METHODS: Twenty fresh cadavers were injected with 20 cc of colored latex through the internal mammary artery. The catheter was placed at the level of the second intercostal space after removal of the rib. The fifth intercostal space was dissected under magnification to observe the origin and trajectory of the fifth anterior intercostal artery perforator. Six selective computed tomographic angiograms of the fifth intercostal artery perforator were performed. A clinical case of nipple-sparing mastectomy in a woman with mammary hypertrophy is provided to demonstrate the utility of preserving the fifth anterior intercostal artery perforator. RESULTS: The fifth anterior intercostal artery perforator was consistently observed in all the cases and confirmed by angiography. The perforator gives rise to several branches that traverse in all directions. The ascending branches of the fifth anterior intercostal artery perforator are directed toward the nipple-areola complex and course within the subcutaneous layer between the skin and the parenchyma. The fourth and fifth anterior intercostal artery perforators are independent of one another. CONCLUSION: The main ascending branch of the fifth anterior intercostal artery perforator reaches the nipple-areola complex by the subcutaneous tissue independently of the Würinger fascia.

ABSTRACT

ABSTRACT: Current understanding of the vascular anatomy of the anterior chest wall suggests that perfusion of the deltopectoral flap may be compromised when crossing the midline at the anterior thoracic wall. The traditional deltopectoral flap is designed longitudinally over the ipsilateral side to avoid the risk of distal flap necrosis. The purpose of this article is to present our experience and results with 26 deltopectoral flaps that were designed and raised with the perforating vessels on the ipsilateral side with the majority of the flap crossing the midline extending to the contralateral side. This anatomic variation in flap design indicates that the sternal midline is not a barrier and that the internal mammary perforator flap may be raised on different longitudinal axes.

ABSTRACT

Surgical treatment of breast cancer has changed during the last few decades. Long-term evaluation of several studies performed worldwide have confirmed that conservative surgery (CS) and radical mastectomy have similar survival rates. Due to CS being the gold standard for treatment for most women with breast cancer, advances in materials, mastectomy and reconstructive surgery techniques, now give us the possibility to perform on our patients a great outcome with oncological security. Both advances, in plastic and oncologic surgery, created a new discipline, called oncoplastic breast surgery, that allow surgeons to resect large breast specimens preventing subsequent deformities with the correct previous planning. This is particularly important when more than 30% of the breast volume will be resected because it allows for planning CS depending on the site of the lesion and for establishing the limits between CS and mastectomy.

ABSTRACT

Advances in reconstructive breast surgery with new materials and techniques now allow us to offer patients the best possible cosmetic results without the risks associated with oncological control of the disease. These advances, in both oncological and plastic surgery, have led to a new field, oncoplastic breast surgery, which enables us to undertake large resections and, with advance planning, and prevent subsequent deformities. This is particularly important when more than 30% of the breast volume is removed, as it allows us to obtain precise information for conservative surgery according to the site of the lesion and to set the boundary between conservative surgery and mastectomy.
