Adipofascial flaps have proven to be an excellent tool for multipurpose reconstruction as free or pedicled flaps. The anatomical studies in this field are now focused on improving esthetics in reconstruction while maintaining a minimal donor site morbidity. An anatomical cadaver study has been carried out to investigate the medial thigh region as a potential donor site for adipofascial flaps. Eighteen thighs from fresh cadavers were dissected and a new territory with autonomous vascular supply was defined through vascular injection, anatomical dissection, transillumination, and angiography. Cutaneous access was made in a "T" shape. The fascia harvests had to be centered on the adductor longus and gracilis muscles bearing in mind the position of the flap pedicle. The fascial flap was isolated from adductor longus and gracilis muscles and isolated on his pedicle (medial circumflex femoral artery). After our anatomical study, we used the flap in 2 clinical cases. The results of our anatomical study and clinical cases confirmed the suitability and reliability of a new flap: the "Medial Fascia Lata Flap." Flap size ranged from 20 to 25 cm and has the advantage of preserving the functionality of the thigh muscles. The study showed that the "Medial Fascia Lata Flap" is easy to harvest, and the resulting scar is concealed. In consideration of its suitability, reliability and aesthetical advantages, it could be proposed as a good option in selected cases., (© 2023 The Authors.)

In this review, we examine the multiple roles of ROS in the pathogenesis of melanoma, focusing on signal transduction and regulation of gene expression. In recent years, different studies have analyzed the dual role of ROS in regulating the redox system, with both negative and positive consequences on human health, depending on cell concentration of these agents. High ROS levels can result from an altered balance between oxidant generation and intracellular antioxidant activity and can produce harmful effects. In contrast, low amounts of ROS are considered beneficial, since they trigger signaling pathways involved in physiological activities and programmed cell death, with protective effects against melanoma. Here, we examine these beneficial roles, which could have interesting implications in melanoma treatment., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2021 Isabella Venza et al.)

Objectives: "Form and function restoration" is the ultimate goal of reconstructive surgery, which is oriented toward regeneration rather than reparation. Recently, research in reconstructive surgery has focused on the regenerative potential of the adipose tissue. The aim of the study is to illustrate the surgical methods and show the functional and aesthetic results achieved by the reconstruction of finger soft-tissue defects using homodigital dorsal adipofascial reverse flap (HDARF)., Materials and Methods: A total of 63 cases (45 acute and 18 elective) were included between September 2010 and August 2016. In each case, we preliminarily performed surgical debridement and then harvested an adipofascial flap from the back of the finger. Nine injured thumbs that were repaired with the flap as emergency cases were also included. The average age of the patients was 46 (range: 4-69) years., Results: All flaps survived without any complications during the 24-month follow-up. Good nail regrowth through the flap and full regeneration were observed in approximately all cases. Sensitivity tests and histological analysis of biopsy samples of the regenerated fingers confirmed full regeneration of the epidermis, dermis, cutaneous adnexa, and nerves. All the patients were satisfied with the hand functionality and aesthetic appearance., Conclusion: The HDARF represents a very useful alternative for the reconstruction of nailbed crushes, achieving regeneration of injured segments in deformities caused by trauma or infection., (© 2018 The Authors.)

Nerve fibers are attracted by sutureless end-to-side nerve coaptation into the recipient nerve. Opening a window in the epineurium enhances axon attraction and myelination. The authors analyze the features of nerve repair by end-to-side coaptation. They highlight the known mechanisms of axon sprouting and different hypotheses of start up signals (presence or absence of an epineurial window, role of Schwann cells, signaling from the distal trunk). The clinical literature is also presented and differences between experimental and clinical applications are pointed out. The authors propose their point of view and perspectives deriving from recent experimental and clinical experiences., Competing Interests: Conflicts of interest: None declared.

Five years after both right ulnar and median nerve decompression for paraesthesias and palsy, a patient, coming from Nigeria but living in Italy, came to our unit claiming to have persistent pain and combined median and ulnar palsy. Under suspicion of leprosy, skin and left sural nerve biopsy were performed. Skin tests were negative, but Schwann cells resulted as positive for acid-fast bacilli (AFB), leading to the diagnosis of Pure Neuritic Leprosy (PNL). The patient was given PB multidrug therapy and recovered from pain in two months. After nine months both High Resolution Ultrasonography (HRUS) and Magnetic Resonance Imaging (MRI) were performed, revealing thickening of the nerves. Since demyelination is common in PNL, the Authors started to use Diffusion Tensor Imaging Tractography (DTIT) to get better morphological and functional data about myelination than does the traditional imaging. DTIT proved successful in showing myelin discontinuity, reorganization, and myelination, and the Authors suggest that it can give more information about the evolution of the disease, as well as further indications for surgery (nerve decompression, nerve transfers, and babysitting for distal effector protection), and should be added to traditional imaging tools in leprosy., Competing Interests: The authors declare that they have no competing interests.

Aim: Cicatricial ectropion is secondary to an excessive scar contraction after trauma, burns, skin conditions, scarring skin tumours, medication, allergies, blepharoplasty complications 1,2. The estimates for ectropion incidence following removal of eyelid lesions have been reported as varying from 2.5% to 7% 3. A variety of surgical techniques can be applied to achieve the correct shape and position of lower lid 4-7. Fat grafts in association with other technique are commonly used in orbital reconstruction in a variety of procedures 8 including of the correction of cicatricial ectropion 9,10., Material of Study: The Authors propose the use of fat graft as only procedure for the correction of cicatricial lower eyelid ectropion. Two male patients with cicatricial ectropion were treated with this technique in two time and followed for 12 months., Results: Lipofilling for cicatricial eyelid ectropion give excellent outcomes, with release of the scar without recurrence, 11., Discussion: Autologous fat grafting has many clinical applications, and its use in Plastic Surgery is increasing: The key point is the presence into fat of Adipose stem cells (ASCs), that have been identified as an ideal source of cells for regenerative medicine, with potential and rapid improvement of healing process and complete recovery of tissue integrity after surgery to confirm the regenerative effect of fat graft., Conclusion: Lipografting can be considered a safe and effective alternative procedure 12,13., Key Words: Defect of lower lid, Ectropion, Lipograft.

Background: Sub-muscular positioning of breast implants requires interrupting as well as disinserting both the abdominal and sterno-chondral fibers of the pectoral muscle; this can produce a muscular strength reduction which reveal bothering and is often detected in some daily motions, such as cutting bread into slices., Material and Methods: The revision of anatomy and literature induced the authors to search for a conservative approach for breast augmentation. They describe a new technique defined "Tri-plane" where the muscular fibers are not cut but simply split to create the pocket for breast implants., Results: Our experience evidenced that this technique gave good aesthetic results together with a more significant projection of the NAC without any strength diminution either in adduction or abduction of the arms., Conclusions: This technique is a valid alternative to other techniques of breast augmentation as it conjugates the advantages of sub-glandular and sub-muscular implants without muscular deficit.

Background: Squamous cell carcinoma (SCC) is the second most common skin cancer in humans. Because the incidence of metastasis from SCC of the skin is rare, regional lymphadenectomy is generally not recommended for the patients with clinically node-negative disease. However, in patients with an intermediate and high risk of metastasis, evaluation of the lymph nodes to detect the absence of metastatic nodal disease is a difficult task., Patients and Methods: The authors reviewed the pertinent demographic and surgical data in a consecutive series of six patients with squamous cell carcinoma who underwent sentinel lymph node staging. The tumour size was greater than 2 cm (T2) and the patients had clinically non-palpable regional lymph nodes (N0). All nodes were examined using haematoxylin-eosin staining. Sentinel Lymph Node Biopsy (SLNB) and Selective Lymphadenectomy (SL) using preoperative lymphoscintigraphy and intraoperative radiolymphoscintigraphy and vital dye injections was used to identify the sentinel lymph node avoiding complete axillary node dissection., Results: No false-negative results were observed. At a median follow-up of 10 months (mean 15 months), neither local or regional recurrences in sentinel node-negative basins have been noted., Conclusions: Sentinel node biopsy is a minimally invasive staging procedure useful in identifying occult regional lymph node disease in selected patients with squamous cutaneous malignancies of the arm. Furthermore sentinel lymph node histology is possibly the most important negative predictor of early recurrence and survival in patients with American Joint Committee on Cancer stage I and II squamous cell carcinoma. Although sentinel node-negative patients are a prognostically favourable group, this small series of patients demonstrates that further studies to verify these findings and develop formal guidelines are indicated

Aim of the Study: The superior pedicle mammaplasty is a technique frequently employed in the treatment of breast ptosis, associated or not with hypertrophy of the gland, followed by satisfactory results. This technique is normally not indicated in severe breast ptosis (pendulous breast) because of the excessive length of the pedicle supplying nipple-areola-complex (NAC), with the risk of ischemia. In these cases the standard technique is the free-nipple-graft mammaplasty. However, the deepen knowledge about vascular anatomy of the breast and the aptitude to perform superior pedicle mammaplasty, induced the authors to indicate this technique even in these cases improving the aesthetic and functional outcomes., Material and Methods: The authors present a series of 30 patient with pendulous breasts, with sternal notch-nipple distance equal or superior to 32 cm (45 cm maximum; mean value 35.1), treated with the superior pedicle mammaplasty with inverted "T" scar. The results confirm the reliability of superior pedicle for the nipple-areolar complex blood supply, associated with satisfactory aesthetic results due especially to the good breast projection., Conclusions: They conclude that superior pedicle technique mammaplasty, even if normally not indicated in these cases, is instead suitable for the treatment of pendulous breasts with great sternal notch-nipple distance, permitting to take advantages of this technique.

Introduction: Coverage of soft tissue defects in the lower leg is often made by use of free flap, also because of the improving of anaesthesiology techniques in the last decades. However, there are disadvantages in the use of free flaps like the need for a remote donor site, increased operative time, use of a major vessel to the leg, and microsurgical skills. Besides these, trauma in the lower limb are often cause of damage for a major vessels of the leg, so the use of free flaps in these patients may be related to an higher incidence of complications; also associated pathologies, like diabetes and vascular pathology, can increase the incidence of complications when a free flap is utilized. In all these cases local fascio-cutaneous flaps, like the sural reverse flap, because of their easy and short time harvesting, can be a very good alternative to free flaps. Superficial sural artery flap is a adipofasciocutaneous flap based on the vascular axis of the sural nerve, which gets reverse blood flow through communication with the perforating branch of the peroneal artery, situated in the region of lateral malleolar gutter., Patients and Methods: Between 2000 and 2005, 11 patients, mean age 68 (range 58-78 years), were treated at the Plastic and Reconstructive Surgery Unit of Messina University, for soft tissue defects of lower limb and foot, using the distally based sural artery flap. The defects were related to post-traumatic damage of soft tissue, diabetic and vascular ulcers, osteomyelitis and oncological resection. Mean follow-up time was 20 months (range 6-55 months). All patients were pre-operatively assessed for vascular patency of peroneal axis and associated morbidity that could increase risk offlap necrosis. This included diabetes mellitus type II, osteomyelitis and peripheral arterial diseases., Results: All flaps survived with the exception of one that sustained partial skin necrosis, in the ratio of 25% of the skin island. All defects were covered with no major complications and none of the patients required a blood transfusion. Moreover aesthetic results were good with satisfaction of all the patients., Conclusion: In our cases we found the sural reverse flap to have a good reliability with low incidence of complication and surgical outcomes. This flap is an excellent option for covering defects of minor deficiency of skin in the third distally of lower limb, ankle and heel. It allows rapid, reliable coverage of defects extending as far distally as the forefoot. Because of the sparing of major vessels, the short surgery time in harvesting the flap, and the good vascular pattern of the flap, we retain the flap a first choose technique for reconstruction in lower leg, especially in politrauma and in patients with associated pathology as vascular diseases or diabetes.

The technology of flap prefabrications is a new, powerful tool in plastic and reconstructive surgery. It is based on an old idea, while applying the latest innovations in surgery. It involves any modification of a surgical flap done before its transfer to the final donor site, including surgical delay, pre-expansion, pre-grafting, the use of tissue engineering, biomaterials and perforators surgery, or the creation of a new pedicle by staged transfer of a vascular bundle. The different possibilities are discussed, with special reference to their biologic basis.
