Superficial Fascia

Localized scleroderma (LS), also called circumscribed scleroderma or morphea, comprises a heterogeneous group of diseases that can be classified into four subtypes: limited, linear, generalized, and mixed LS. All manifestations are primarily due to chronic progressive fibrosis of the skin or structures close to the skin. Involvement of internal organs or the transition to systemic sclerosis is excluded by definition. A distinction is made between forms that primarily affect the skin (up to the dermis) or that severely involve subcutaneous fat tissue, muscle fascia or muscles...

Following its initial description by Koshima in 2004, the superficial circumflex iliac artery perforator (SCIP) flap has become a ubiquitous and extremely useful flap in coverage of defects whereby bulkiness must be avoided. It also allows direct closure and concealment of the donor site. Its use as a free tissue transfer has been demonstrated by various surgeons globally. Nevertheless, there are few cases illustrating the utility of the pedicled SCIP flap in the reconstruction of lower abdominal defects. We present a case of a pedicled SCIP flap utilized as a chimeric flap incorporating external oblique muscle fascia on a deep branch along with the typical fasciocutaneous component based on the superficial branch to cover the suprapubic defect after vesicocutaneous fistula repair...

Nodular fasciitis (NF) is a benign, reactive, myofibroblastic proliferative solitary lesion that commonly develops in the subcutaneous or superficial fascia. We present a case of a 35-year-old male with a rapidly enlarging upper eyelid mass postiatrogenic incisional trauma. Subsequent en toto excisional biopsy demonstrated NF. Given the rapid clinical course of this patient and the reactive nature of NF, we hypothesize that the initial incisional trauma likely incited an inflammatory response resulting in rapid proliferation and growth of the lesion...

BACKGROUND: The anterolateral thigh flap (ALTF) is a kind of lateral thigh flap that uses branches of the lateral circumflex femoral artery (LCFA) as the vessel pedicle and is widely used in plastic surgery. During classic ALTF surgery, some perforators from the descending branch of the lateral circumflex femoral artery (LCFA-db) are hard to harvest due to their anatomical variants and individual differences; thus, it is necessary to design an appropriate alternative surgical plan. The transverse branch of the LCFA (LCFA-tb) has unique advantages and can be a potential complement to ALTF vascular pedicle selection...

OBJECTIVE: The superficial cervicofacial musculoaponeurotic system (SMAS) is a complex network formed by mimic muscles and conjunctive tissue of the superficial fascia of the face.This study aimed to introduce new anatomofunctional data on the importance of the trans-SMAS distribution pattern of the skin microperfusion of the face and to underline the role of SMAS in maintaining the homeostasis of the vascular network that crosses it. Considering the fibrous and muscular matrix of the SMAS, using COLIII and MyoH2 antibodies, together with endothelial immunohistochemistry(IHC)intercellular adhesion molecule 2 marker, we determined the correlation of these structures and their interaction...

BACKGROUND: Injections around the Achilles tendon (AT) are commonly performed in clinical practice to manage non-insertional Achilles tendinopathy, but the presence/distribution of the injectate with relation to its sheath has not been assessed specifically. Accordingly, the aim of this cadaveric investigation was to demonstrate the feasibility of Achilles paratenon injection under ultrasound guidance - by confirming the exact needle positioning as well as the dye distribution inside the paratenon lumen...

Dendritic fibromyxolipoma (DFML) is a benign, very rare, and slow-growing soft tissue tumor commonly involving the muscular fascia of the foot, calf, shoulders, back, or head and neck muscles. Many authors consider dendritic fibromyxolipoma a variant of spindle cell lipoma composed of a plexiform vascular pattern, dendritic cytoplasmic processes, and keloidal collagen. Only a few cases have been reported in the shoulder region, and the presented case represents the second case in English literature whose histopathology showed intramuscular involvement...

INTRODUCTION: Thread lifting is a non-surgical cosmetic procedure that utilizes threads to lift and tighten sagging skin on the face. In Lateral face lifting with anchoring technique, the threads are inserted into the skin and anchored in place to provide support to the skin at artery free zone. This technique utilizes a long cog thread, allowing for stronger fixation points. The optimal location for thread anchoring is in the fascia of the treatment area. METHOD AND MATERIALS: The study was performed with twelve cadavers with twenty-four specimens of head from cadavers and was processed using phosphotungstic acid-based contrast enhancement micro-computed tomography and conventional computed tomography...

BACKGROUND: Histologic grade, size, and depth are well-known prognostic factors in soft tissue sarcomas (STS). Small (< 5 cm) and superficial STS generally have an excellent prognosis when treated with appropriate surgery. However, they are often misdiagnosed and mistreated. We reported that in midterm follow-up (5 to 7 years), patients with unplanned resections of tumors with positive margins who immediately underwent a reoperation with margin-widening re-resection and postoperative radiotherapy had survival comparable to that of patients who were initially treated correctly...

OBJECTIVE: To investigate the clinical application of high-frequency color Doppler ultrasound (HFCDU) in detecting perforators in the deep adipose layers for harvesting super-thin anterolateral thigh flap (ALTF). METHODS: Between August 2019 and January 2023, 45 patients (46 sides) with skin and soft tissue defects in the foot and ankle were treated, including 29 males and 16 females, aged from 22 to 62 years, with an average of 46.7 years. The body mass index ranged from 19...

Introduction Incisional hernia is a common complication of midline laparotomy that may develop even after several years of surgery. Abdominal fascia closure with ideal suture material reduces the incidence of incisional hernia. This study compared the clinical equivalence of PD Synth (Healthium Medtech Limited) and PDS (Ethicon, Johnson & Johnson) slowly absorbed polydioxanone suture with respect to the occurrence of incisional hernia, following elective/emergency midline laparotomy. Methods Eighty-eight subjects undergoing elective/emergency midline laparotomy were randomized to PD Synth (n=45) and PDS (n=43) groups of this prospective, multicenter, randomized (1:1), single-blind, two-arm, parallel-group study (December 2020-May 2023)...

BACKGROUND AND OBJECTIVES: The temporoparietal fascia (TPF) flap is an alternative for revision endoscopic skull base reconstruction in the absence of the nasoseptal flap, and we aimed to investigate the anatomy and surgical application of TPF flap transposition in endoscopic endonasal surgery. METHODS: Six lightly embalmed postmortem human heads and 30 computed tomography angiography imaging scans were used to analyze the anatomic features of the TPF flap transposition technique...

BACKGROUND: The suspensory ligamentous system of the penis supports the penis when erect and plays a key role during coitus. These ligaments are prone to injury during coitus and clinically they are important in penile reconstruction procedures. The origin, course, insertion, dimensions, and tissue composition of these ligaments is highly debated and not clearly elucidated. OBJECTIVES: The current study investigated the macro and micro-anatomy of the suspensory ligamentous system of the penis...

Musculoskeletal infections in the ER are not an uncommon presentation. The clinical context is critical in determining the suspicion for infection and degree of tissue involvement which can involve all layers from the skin to bones. The location, extent, and severity of clinically suspected infection directly relate to the type of imaging performed. Uncomplicated cellulitis typically does not require any imaging. Localized and superficial infections can mostly be evaluated with ultrasound. If there is a diffuse site (an entire extremity) or suspected deeper involvement (muscle/deep fascia), then CT is accurate in diagnosing, widely available, and performed quickly...

OBJECTIVE: To explore the feasibility and effectiveness of plantar medial thin skin flaps preserving plantar fascia with its superficial fascia tissue to repair skin defects in hands and feet. METHODS: Between July 2017 and January 2023, 35 cases of hand and foot defects were repaired with plantar medial thin skin flaps preserving plantar fascia with its superficial fascia tissue (13 pedicled flaps and 22 free flaps). There were 18 males and 17 females, with an average age of 38...

Objective: To investigate the architecture of the cutaneous branch-chained blood vessels in the medial lower leg and provide the anatomical basis for design and clinical application of the cutaneous branch-chained flap from this region. Methods: The experimental research method was used. From March to May 2023, the anatomical study was conducted on the 5 voluntarily donated fresh adult (aged 50 to 70 years, all male) cadaveric specimens from Hangzhou Normal University School of Basic Medical Sciences. The fine anatomy under microscope was performed on each lower leg specimens of 5 corpses (1 lower leg specimen was conducted with digital radiography (DR) scan before fine anatomy), to observe, measure, and record the course of posterior tibial artery, quantity of perforator, the distance between the perforating point of each perforator and the medial condyle of tibia, the external diameter of posterior tibial artery perforator, the length of perforator pedicle, the horizontal distance between the posterior tibial artery perforator and the saphenous nerve, and the course of each perforator within superficial fascia after crossing the deep fascia and the distribution of the cutaneous branch-chains...

The study analyzed vascular variations in microtia associated with hemifacial microsomia (HFM). A retrospective analysis was conducted on 47 patients with microtia and HFM, who underwent computed tomography angiography between November 2011 and May 2022. The vascular course and branching supplying the TPF were analyzed. Craniometric measurements were conducted to determine the horizontal distance from the porion and fronto-zygomatic suture (F-Z suture) to the vessels. On the affected side, the TPF was primarily supplied by either the superficial temporal artery (STA) or the postauricular artery-originated STA (Po-STA)...

Lymphedema is characterized by the abnormal accumulation of lymphatic fluid in the skin and subcutaneous tissue owing to impaired lymph flow. This condition may be primary or secondary to other diseases. Most lymphedema occurs in the lower extremities, which greatly interferes with the activities of the patients, especially walking. Further, it may affect the psychological condition of patients. In Indonesia, several patients with severe lymphedema have visited our clinic. In our center, lymphography is not available...

Delayed onset muscle soreness (DOMS) of the lower back is considered a surrogate for acute low back pain (aLBP) in experimental studies. Of note, it is often unquestioningly assumed to be muscle pain. To date, there has not been a study analyzing lumbar DOMS in terms of its pain origin, which was the aim of this study. Sixteen healthy individuals (L-DOMS) were enrolled for the present study and matched to participants from a previous study (n = 16, L-PAIN) who had undergone selective electrical stimulation of the thoracolumbar fascia and the multifidus muscle...

BACKGROUND: Previous studies demonstrated that mast cells with their degranulated component heparin are the major endogenous factors that stimulate preadipocyte differentiation and promote fascial adipogenesis, and this effect is related to the structure of heparin. Regarding the structural and physiological properties of the negatively charged polymers, hexasulfonated suramin, a centuries-old medicine that is still used for treating African trypanosomiasis and onchocerciasis, is assumed to be a heparin-related analog or heparinoid...
