RESUMEN

Carbon peel laser treatment has been described for the improvement of skin texture, with pore reduction and acne lesion treatment. The technique consists of applying a carbon mask to the face for about ten minutes followed by laser irradiation with a Q-switched 1064 nm laser. This mechanism of action seems to be related to small carbon molecules binding both the corneocytes and serum within the hair follicles; the effect of the laser eliminates carbon bound to skin particles and the high temperature generated reduces sebum production by sebaceous glands and inhibits Cutibacterium acnes replication. Although this method was described 20 years ago, scientific data supporting its efficacy and safety have only recently been reported in small case series. For this reason, we performed a retrospective study including patients treated from January to May 2022 in the context of a private practice. Even if this study is limited by the low number of patients and its retrospective nature, this is the first research to show that carbon peel laser, performed with a standardized technique, is an effective and safe treatment for patients with acne lesions, showing pores and wrinkles, and is able to improve the overall skin aspect.

RESUMEN

Botulinum neurotoxin-A and botulinum neurotoxin-B have been shown to play a potential role in improving flap survival in animal models. The aim of this study is to review indications as well as to study injection timing, technique, and doses of botulinum neurotoxin-A and botulinum neurotoxin-B in animal models. Seventeen articles describe a total of 266 animals that underwent botulinum toxin injections before or during flap harvesting or vascular anastomosis procedure. All the studies demonstrated a beneficial effect of botulinum toxin administration in flap surgery or vascular anastomosis. Botulinum neurotoxin-A injection was shown to be a reliable approach in reducing vascular complications rate and increasing survival of flaps in animal models. The main conclusions drawn from the study include the following: perivascular injections targeting each vascular pedicle are preferred in cases of free flaps or axial flaps; subdermal injections are favorable in cases of random pattern skin flaps; and injections should be performed 7 days before flap elevation.

RESUMEN

BACKGROUND: Nasal septal deviation is one of the major causes of nasal respiratory flow disorders. During the rhinoseptoplasty, the septum can be treated through a closed traditional access or through an open access. To date, there are still no objective functional indications of the best access to use in rhinoseptoplasty. For this reason, we evaluated, objectively and subjectively, the functional efficiency of open access and compared it with that of closed access. The aim is to highlight any functional outcome differences between the 2 types of access. METHODS: The study involved up to 50 patients, from January 2006 to June 2017; 20 patients underwent modified extracorporeal rhinoseptoplasty with open access, and 30 patients underwent modified extracorporeal rhinoseptoplasty with closed access. We evaluated the nasal obstruction by using the validated questionnaire Nasal Obstruction Symptoms Evaluation (subjective method) and by performing the anterior active rhinomanometry (objective method). Both evaluations were performed in 3 different times: preoperative period, 3 months, and 6 months after surgery. RESULTS: In the open cohort, the rhinomanometric analysis showed a statistically significant increase between preoperative period and sixth month after surgery; however, the nose score had a statistically significant increase in both 3 and 6 months after surgery. At 3 months after surgery, the rhinomanometric score was higher in patients with closed access than patients with open access; this difference has disappeared at 6 months after surgery. At 3 and 6 months after surgery, the improvement in the Nasal Obstruction Symptoms Evaluation average score was greater in patients with open access compared with patients with closed access. No complications were observed. CONCLUSIONS: Based on the results obtained from our work, we can declare that open access is a functionally valid procedure. At 6 months after surgery, the 2 accesses have a comparable functional efficacy.

RESUMEN

INTRODUCTION: Skin-sparing mastectomy (SSM) entails complete removal of the breast tissue and the nipple and areola complex (NAC) with preservation of as much of the overlying skin as possible. The preservation of the natural skin envelope during SSM improves the aesthetic outcome of immediate breast reconstruction, but the lack of NAC determines that the reconstructed breast remains anatomically incomplete with not always satisfactory final results. For this purpose, the aim of the present study was to investigate and evaluate the impact of nipple reconstruction after skin sparing and skin reducing mastectomy on the patients' perception and intimate life. MATERIALS AND METHOD: This was a comparative single-center prospective study that involved 42 patients underwent NAC reconstruction after SSM. A pre- and postoperative quality-of-life and psychological questionnaires Breast-Q questionnaire (Breast Conserving therapy module) were given to all the patients before the surgery and 6 months after. The statistical analysis with chi-square test was performed. RESULTS: After 6 months a prevalence of patients reported to be very satisfied in regard to shape, appearance, naturalness, projection, position and symmetry. The study shows an overall improvement in all the psychological items analyzed with statistically significant difference regarding: "patient's satisfaction," "self-confidence," "appearance of the breast." CONCLUSION: The authors believe that the NAC reconstruction has useful functional and aesthetic results particularly appreciated by patients who feel demoralized after breast demolition surgery.

RESUMEN

INTRODUCTION: Breast-conserving surgery (BCS) is a valid method for the reconstruction of partial breast defects, however, there is a great variety of final aesthetic outcomes depending on the location of the tumor in the breast and also on the initial breast volume and the degree of ptosis. Specifically, defects affecting the upper inner/central quadrant represent a reconstructive challenge with not always satisfactory final results. For this purpose, the authors investigated the use of the central mound technique in breast-conserving surgery. The aim of the study was to apply the central mound as an oncoplastic technique and assess the satisfaction rate of the patients. MATERIALS AND METHODS: This was a retrospective study that involved 40 patients (80 breast) underwent breast conserving surgery and contextual bilateral breast remodeling with central mound technique. A pre- and postoperative Breast-Q questionnaire (breast conserving therapy module) was given to all the patients before the surgery, 3 months and 9 months after. The statistical analysis with chi-square test was performed. RESULTS: After 9 months the author found a major increase of all BREAST-Q parameters; the most valuable increments concerned the "Satisfaction with breast" and "Psychosocial well-being." None of the patients experienced a decreased in the quality of life related to the surgical procedure. CONCLUSION: The authors believe that this technique has useful functional and aesthetic results particularly appreciated by patients with upper pole lesion who have a slightly or moderately breast ptosis and a small cup size.

RESUMEN

INTRODUCTION: Seroma is a common complication after prepectoral prosthetic breast reconstruction with ADM, leading to wound dehiscencse, infection, and even loss of reconstruction at last. A new ultrasound (US) guided follow-up protocol has been applied to compare primary and secondary complications incidence and their treatment, and evaluate the effect of precocious seroma detection and its evacuation in reducing secondary complications. METHODS: We enrolled 406 patients from January 1st, 2021 to July 1st, 2023 who underwent mastectomy and 1-stage prepectoral reconstruction with ADM. Experimental group counted 96 patients, whom have been treated as protocol fashion, therefore with multiple US-guided evaluations and eventual evacuations along with postoperative period; control group (310 patients) has exclusively been clinically evaluated. RESULTS: Seroma incidence detected rate among experimental group, after 1-year follow-up, was 32.2%, compared to 16.8% in control cohort, additionally no other secondary complications were detected in the first group. Referring to the wound dehiscence incidence, a statistically significant higher frequency was observed in control group compared with treatment 1 (21.2% vs. 0%; P = .0027). CONCLUSIONS: Seroma and correlated secondary complications may lead to additional surgeries, higher sanitary costs and even reconstructive failure. With a seriated US follow-up protocol application, the surgeon could promptly manage and treat seroma, decreasing additional complications rate, particularly wound dehiscence. LEVEL OF EVIDENCE: III.

RESUMEN

Background: In prepectoral breast reconstruction (PPBR) the acellular dermal matrix (ADM)'s integration capacity into the tissue is known. The aim of this study was to analyze the effect of the ADM on development and composition of the peri-implant breast capsule in a dynamic setting of breast tissue expansion during two-stage prepectoral breast reconstruction. Methods: This is a prospective single-center study in which 50 patients who underwent mastectomy and breast reconstruction with prepectoral tissue expander and Braxon ADM (group A) and submuscular tissue expander (group B) were enrolled. One-year post implantation hematoxylin & eosin (H&E) staining and immunohistochemistry analyses were done on capsule tissue samples. Results: The analysis conducted on H&E-stained samples showed a significant reduction of cellular density and a decrease of the cellular infiltration in capsules of ADM-covered expanders compared with naked expander capsules (P < 0.05). The immunohistochemical analyses showed that group A capsules presented significantly less M1 CD68+ macrophages (P < 0.05), lower alfa-SMA expression levels, and a lower number of myofibroblasts (P < 0.05) compared with group B capsules. Presence of lymphatic vessels was minimally detected in both groups. Conclusions: The ADM presence around the prepectoral tissue expander influences the development of the peri-implant capsule, causing a significant reduction of the number of cells and inflammatory infiltrate, especially M1 macrophages and myofibroblasts. The ADM Braxon is therefore effective in creating a noninflamed capsule around the implant and in dynamic tissue conditions, and such an environment is maintained in time.
