RESUMEN
The purpose of this study was to assess the medium-term results of using thread-lift sutures as a means to support soft tissues in facial reconstructive surgery. The rationale for the introduction of this method was to provide support for tissues used in the reconstruction in cases where this would otherwise have been difficult to achieve, or would have demanded major additional surgery in patients already undergoing major surgical procedures. The outcome of the procedure was assessed 12 and 24 months after surgery. Patients were satisfied with the results. Judging from the findings of this study, Silhouette sutures are a valuable asset in facial reconstruction surgery when associated with a scrupulous technique and used for the right indications.

OBJECTIVE: We will present our experience in vulvar reconstruction using a local fascio-cutaneous flap, in order to get an easier intra-operative management and a good post-operative outcome. METHODS: Between May 2006 and December 2008, eight patients with vulvar carcinomas underwent a vulvar reconstruction, using a V-Y advancement flap of the gluteal fold. This fascio-cutaneous flap, based on the perforator vessels originated from the internal pudendal artery, was used for the reconstructive treatment of patients who had undergone a vulvectomy with medium-size defects. RESULTS: All the 16 flaps prepared survived without major complications. Walking and sitting positions were restored in few post-operative days. Length of hospitalisation was 2-3 weeks. The flaps restored sensitivity few months after surgery. In no case the surgical scars needed being revised. CONCLUSIONS: The follow-up results proved satisfactory in terms of patients' compliance and morphological results. The flap appeared to be thin, well vascularised and very flexible in its advancement. The post-operative follow-up is characterised by a rapid healing and a low incidence of short- and long-term complications.

BACKGROUND: After loss of a thumb, the big toe is a possible donor site for reconstruction with wrap-around free flap and trimmed-toe transfer techniques. Early reconstructions seem to reduce the risk of post-operative infections, despite several studies that show different infection rates of the recipient site in immediate toe-to-hand transfer. The authors carried out a retrospective analysis of their experience in thumb reconstruction with big toe transfer and evaluated the results achieved with both immediate and delayed reconstructions in terms of infection occurrence. PATIENTS AND METHODS: From 2000 to 2017, patients who presented cut, crush and avulsion injuries in the thumb were selected and 33 toe-to-thumb transfers were performed. Patients were divided into two groups: in group A, patients underwent immediate reconstruction, while in group B delayed reconstructions were performed. The two groups received identical antimicrobial prophylaxis. Reliability of the immediate or delayed reconstruction was compared in terms of flap survival, requirement for a secondary intention healing and, in particular, rate of infection. RESULTS: 29 male and 4 female patients were treated. Toe-to-thumb transfers were performed in both groups: in group A, 8 wrap-around free flaps and 4 trimmed toe transfers; in group B, 11 wrap-around and 10 trimmed toe transfers. No flap loss occurred in either groups. No cases of infection were detected in the transferred toes. CONCLUSION: For toe-to-thumb transfer, there are published reports of a wide range of infection rates of the recipient sites. The authors compared their results in terms of infection rate between immediate reconstruction, group A, and delayed reconstruction, group B. Immediate toe-to-thumb transfer showed equal success rates to delayed transfer. No statistically significant difference in risk of infection between the two groups was found. Results showed that the immediate reconstruction was as safe and reliable as the delayed one.

INTRODUCTION: Autologous fat grafting is commonly used to correct soft-tissue contour deformities. However, results are impaired by a variable and unpredictable resorption rate. Autologous adipose-derived stromal cells in combination with lipoinjection (cell-assisted lipotransfer) seem to favor a long-term persistence of fat grafts, thus fostering the development of devices to be used in the operating room at the point of care, to isolate the stromal vascular fraction (SVF) and produce SVF-enhanced fat grafts with safe and standardized protocols. Focusing on patients undergoing breast reconstruction by lipostructure, we analyzed a standard technique, a modification of the Coleman's procedure, and three different commercially available devices (Lipokit, Cytori, Fastem), in terms of 1) ability to enrich fat grafts in stem cells and 2) clinical outcome at 6 and 12 months. METHODS: To evaluate the ability to enrich stem cells, we compared, for each patient (n=20), the standard lipoaspirate with the respective stem cell-enriched one, analyzing yield, immunophenotype and colony-forming capacity of the SVF cells as well as immunophenotype, clonogenicity and multipotency of the obtained adipose stem cells (ASCs). Regarding the clinical outcome, we compared, by ultrasonography imaging, changes at 6 and 12 months in the subcutaneous thickness of patients treated with stem-cell enriched (n=14) and standard lipoaspirates (n=16). RESULTS: Both methods relying on the enzymatic isolation of primitive cells led to significant increase in the frequency, in the fat grafts, of SVF cells as well as of clonogenic and multipotent ASCs, while the enrichment was less prominent for the device based on the mechanical isolation of the SVF. From a clinical point of view, patients treated with SVF-enhanced fat grafts demonstrated, at six months, a significant superior gain of thickness of both the central and superior-medial quadrants with respect to patients treated with standard lipotransfer. In the median-median quadrant the effect was still persistent at 12 months, confirming an advantage of lipotransfer technique in enriching improving long-term fat grafts. CONCLUSIONS: This comparative study, based on reproducible biological and clinical parameters and endpoints, showed an advantage of lipotransfer technique in enriching fat grafts in stem cells and in favoring, clinically, long-term fat grafts.
