[Clinical diagnosis and treatment of 14 cases of scar cancer ulcer wound on head and face].

Objective: To analyze the clinical characteristics of scar cancer ulcer wound of head and face, and to investigate its diagnosis and treatment. Methods: The clinical data of 14 patients with head and facial scar cancer ulcer wounds who met the selection criteria and admitted between January 2021 and March 2022 were retrospectively analyzed. There were 8 males and 6 females. The age of onset ranged from 21 to 81 years with an average age of 61.6 years. The incubation period ranged from 1 month to 70 years, with a median of 4 years. Site of the disease included 7 cases of head, 6 cases of maxillofacial region, and 1 case of neck region. Injury factors included trauma in 5 cases, scratch in 5 cases, scalding in 2 cases, burn in 1 case, and needle puncture in 1 case. Pathological results showed squamous cell carcinoma in 9 cases, basal cell carcinoma in 3 cases, sebaceous adenocarcinoma in 1 case, papillary sweat duct cystadenoma combined with tubular apocrine sweat gland adenoma in 1 case. There was 1 case of simple extensive tumor resection, 1 case of extensive tumor resection and skin grafting repair, 7 cases of extensive tumor resection and local flap repair, and 5 cases of extensive tumor resection and free flap repair. Results: All the 14 patients were followed up 16-33 months (mean, 27.8 months). Two patients (14.29%) had scar cancer ulcer wound recurrence, of which 1 patient recurred at 2 years after 2 courses of postoperative chemotherapy, and was still alive after oral traditional Chinese medicine treatment. One patient relapsed at 1 year after operation and died after 2 courses of chemotherapy. One patient underwent extensive resection of the left eye and periocular tumor and the transfer and repair of the chimaeric muscle axial flap with the perforating branch of the descending branch of the left lateral circumflex femoral artery, but the incision healing was poor after operation, and healed well after anti-infection and debridement suture. The wounds of other patients with scar cancer ulcer did not recur, and the wounds healed well. Conclusion: Scar cancer ulcer wound of the head and face is common in the middle-aged and elderly male, and the main pathological type is squamous cell carcinoma. Local extensive resection, skin grafting, or flap transfer repair are the main treatment methods. Early active treatment of wounds after various injuries to avoid scar repeated rupture and infection is the foundamental prevention of scar cancer.

The Application of Preoperative Computed Tomography Angiography and Color Ultrasound Assisted Lower Limb Perforator Flap Design in the Repair of Lower Limb Soft Tissue Defects.

Objective: The goal of this study was to explore the application effect of preoperative computed tomography (CT) angiography and color ultrasound-assisted design of lower limb perforator flaps in the repair of lower limb soft tissue defects. Repair of soft tissue defects in the lower limbs is a challenging surgical task, and accurate preoperative location of vascular structures and detailed design of the surgical plan are crucial to the success of the surgery. This study aims to improve the accuracy and effectiveness of lower limb perforator flap repair surgery by introducing CT angiography and color ultrasound technology. Methods: Sixty-four patients who underwent lower limb soft tissue defect repair with perforator flaps were enrolled at our hospital from February 2020 to February 2023. According to their admission time, they were divided into two groups: 32 patients admitted before June 31, 2022, were included in the control group, and preoperative color Doppler ultrasound was used to assist in designing the lower limb perforator flap; 32 patients admitted after June 31, 2022, were included in the study group, and preoperative CT angiography and color Doppler ultrasound were used to assist in designing the lower limb perforator flap. Specifically, we conducted detailed records and analyzes of patients' age distribution, gender ratio, and relevant medical history. This demographic information will help reveal whether there are differences in the effectiveness of preoperative CT angiography and color ultrasound-assisted lower extremity perforator flap design among different patient groups. By considering these key factors, we can more accurately assess the actual utility of new technologies in different patient groups and provide more specific guidance for clinical practice.The therapeutic effects of the two groups of patients were recorded. The differences between the preoperative CT angiography measurements and intraoperative actual measurements of the study group were compared. Clinical indicators, sensory function in the graft area, flap survival rate, flap complication rate, and donor area complication rate were compared between the two groups. The satisfaction of patients in the two groups with the recovery of the surgical area was also compared. Results: The treatment success rate of the study group was higher than that of the control group (P < .05). There was no significant difference in the preoperative CT angiography measurements (shallow branch localization, shallow branch starting diameter, shallow branch length, deep branch starting diameter) and intraoperative actual measurements of the study group (P > .05). The operation time and intraoperative blood loss of the study group were shorter than those of the control group (P < .05), and there was no significant difference in flap harvesting area and length of hospital stay between the two groups (P > .05). There was a difference in sensory function in the graft area between the two groups, with a higher proportion of S4 grade in the study group and better recovery compared to the control group (P < .05). There was no significant difference in satisfaction evaluation between the two groups (P > .05). Conclusion: Preoperative CT angiography and color ultrasound-assisted design of lower limb perforator flaps have shown significant clinical advantages in repairing lower limb soft tissue defects, improving treatment effects and surgical efficiency. In clinical practice, this technology is expected to reduce surgical complexity, shorten surgical time, reduce the risk of intraoperative bleeding, and achieve effective defect repair while maintaining or improving the patient's sensory function.However, there are some limitations to the study, such as the relatively small sample size and single-center nature. Future research can optimize the operation process of this technology, expand the scope of research, and explore its application in the repair of soft tissue defects caused by specific causes. This technology may provide more precise and effective options for personalized treatment, especially for patients who need to preserve more sensory function.

[Curative effects of bi-pedicled deep inferior epigastric perforator flap in repairing large soft tissue defects in the lower limbs].

Objective: To investigate the curative effects of bi-pedicled deep inferior epigastric perforator (DIEP) flap in repairing large soft tissue defects in the lower limbs. Methods: A retrospective observational study was conducted. From February 2016 to June 2020, 16 patients with large soft tissue defects in the lower limbs caused by trauma or after tumor/scar resection were admitted to the Department of Hand Surgery of the Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University, including 9 males and 7 females, aged 25-58 years, with the area of soft tissue defects ranging from 14.0 cm×8.0 cm to 32.0 cm×18.0 cm. Using the abdomen as the donor site, the conjoined abdominal wall flap, i.e., the bi-pedicled DIEP flap (with an area ranging from 15.0 cm×9.0 cm to 32.0 cm×20.0 cm) carrying two sets of the trunk of the deep inferior epigastric artery was designed and resected to repair the wound. The donor site wound was sutured directly. The flap survival and wound healing in the donor and recipient areas were observed after operation. The curative effect was evaluated during the follow-up. At the last follow-up, the American Knee Society score and lower extremity functional scale were used to assess the functions of knee joint and lower limb, respectively. Results: The flaps of 15 patients survived after operation; the flap of one patient had partial infection at the edge after operation but healed after debridement and dressing change. The wounds in the donor and recipient areas of 16 patients all healed well. Follow-up of 16-28 months showed that the recipient area had a good shape and pliable texture, and there was no obvious swollen appearance, hyperpigmentation, or abnormal hair growth; the donor site had linear scar only, with no complications such as abdominal hernia or hyperplastic scar; the functions of knee joint and lower limb were well reconstructed, with no recurrence of tumor. At the last follow-up, among the 4 patients with knee joint injury, 3 cases were excellent and 1 case was good in the evaluation of knee joint function; among the 12 patients with lower limb injury, 9 cases were excellent and 3 cases were good in the evaluation of lower limb function. Conclusions: The donor site of bi-pedicled DIEP flap is concealed with abundant tissue and large area for resection, with which can be used to repair large soft tissue defects in the lower limbs, achieving good short-term results of appearance and function restoration.

The Impact of Flap Vascular Pressurization Technique on the Repair of Large-Area Soft Tissue Defects in Limbs.

Objective: This study investigated the impact of the flap vascular pressurization technique on repairing large-area soft tissue defects in the limbs. Methods: This study employed a randomized controlled trial design to enroll patients with large-area skin defects in the limbs, accompanied by exposed deep tissues such as nerves, blood vessels, bones, and tendons, for various reasons between July 2020 to July 2022. The patients were randomly assigned into two groups using a random number table method. The control group (n = 30) underwent traditional anterior lateral thigh flap repair, while the experimental group (n = 30) underwent flap repair using the vascular pressurization technique. Clinical indicators, flap survival, scar formation, and satisfaction were compared between the two groups. Results: There were no significant differences in operation time, intraoperative blood loss, and length of hospital stay between the two groups (P > .05). The flap survival rate in the experimental group (90.00%, 27/30) was significantly higher than that in the control group (66.67%, 20/30) (P < .05). The Manchester Scar Scale (MSS) scores in the experimental group were significantly higher than those in the control group (P < .05). The satisfaction rate in the experimental group (93.33%, 28/30) was significantly higher than that in the control group (73.33%, 22/30) (P < .05). Conclusion: The use of the flap vascular pressurization technique for the repair of soft tissue defects in the limbs can significantly increase flap survival rate, improve scar formation, and enhance patient satisfaction, thereby demonstrating good clinical value. The flap vascular pressurization technique can be promoted as a reliable method for repairing large-area skin defects in the limbs, thereby contributing to the advancement of specialized fields.

Treatment of Multiple Finger Laceration Caused by Green Onion Cutting Machines in South Korea.

Background: Finger injuries caused by green onion cutting machines in Korean kitchens have unique characteristics of an incomplete amputation in which multiple parallel soft tissues and blood vessels are injured in the same form. In this study, we aimed to describe unique finger injuries and to report the treatment outcomes and experiences of performing possible soft tissue reconstructions. Methods: This case series study included 65 patients (82 fingers) from December 2011 to December 2015. The mean age was 50.5 years. We retrospectively classified the presence of fractures and the degree of damage in patients. The injured area involvement level was categorised as distal, middle or proximal. The direction was categorised as sagittal, coronal, oblique or transverse. The treatment results were compared according to the amputation direction and injury area. Results: Of the 65 patients, 35 had a partial finger necrosis and needed additional surgeries. Finger reconstructions were performed through stump revision or local or free flap use. The survival rate was significantly lower in patients with fractures. As for the injury area, distal involvement led to 17 out of 57 patients displaying necrosis and all 5 patients showing the same in proximal involvement. Conclusions: Unique finger injuries caused by green onion cutting machines can easily be treated with simple sutures. Then prognosis is affected by the extent of injury and the presence of fractures. Reconstruction is necessary for finger necrosis owing to extensive blood vessel damage and limitations when making this selection. Level of Evidence: Level IV (Therapeutic).

Multidisciplinary treatment of a complicated crural degloving injury in a diabetic patient.

Diabetes is a common disease that potentially interferes with healing processes after lower limb trauma. In our presented case a trimalleolar ankle fracture with undiscovered serious soft-tissue injuries resulted in chronic soft-tissue complications in a diabetic patient, requiring three and a half months of hospitalization in a higher level center and the application of state-of-the-art wound treatment, including vacuum-assisted closure therapy, Integra bioengineered skin substitute, split-thickness skin-grafting, and methods enhancing wound healing, such as polarized light therapy and transdermal CO2 delivery. The presented case emphasizes the importance of soft-tissue care and multidisciplinary approach in diabetic trauma patients with poor compliance.

Lower limb paediatric trauma with bone and soft tissue loss: Ortho-plastic management and outcome in a major trauma centre.

AIM: We examined the management and outcome of patients suffering complex paediatric lower limb injuries with bone and soft tissue loss. METHOD: Patients were identified from our prospective trauma database (2013-2018). Inclusion criteria were age (<18 years) and open lower-limb trauma. We assessed severity of soft tissue and/or bone loss, fracture complexity, surgical techniques and time to surgery. Paediatric quality of life and psychological trauma impact scores (HRQOL and CRIES), Ganga Hospital Injury Severity score (GHISS), union and complication rates were measured. RESULTS: We identified 32 patients aged between 4 and 17 years. Twenty-nine patients had open tibia fractures including 14 patients with bone loss, one patient had an open femur fracture, one patient an open talus fracture and one an open ankle fracture with dorsal degloving. Thirty injuries were classified intra-operatively as Gustilo IIIB (or equivalent) and two injuries as Gustilo IIIC. In 10 patients primary skin closure was achieved by acute shortening following segmental bone loss. Twenty-two patients required soft tissue coverage: 17 free vascularised flaps, two fascio-cutaneous flaps and three split skin grafts were used. Two patients required vascular repair. Soft tissue coverage was achieved within 72 hours in 26 patients (81%) and within a week in 30 patients (94%). The surgical techniques applied were: circular fine wire frame (19), monolateral external fixator (4) and open reduction internal fixation (8). Median follow up time was 18 (7-65) months. Paediatric quality of life scores were available in 30 patients (91%) with a median total score of 77.2 out of 100. The psychological trauma impact scores showed one in three patients was at risk of developing post-traumatic stress symptoms (PTSD). The GHISS scores ranged from 6-13. All fractures went on to unite over a median time of 3.8 (2-10) months. Three patients (9%) had major complications; two flap failures requiring revision, one femur non-union requiring revision fixation. CONCLUSION: Limb salvage and timely fracture union is possible in children with complex lower limb trauma. Early intervention providing adequate debridement, skeletal stabilisation and early soft-tissue cover including the option of free microvascular reconstruction in small children when required, delivers acceptable outcomes. A multidisciplinary team approach including clinical psychologists to address the psychological impact of trauma provides optimal holistic care for these children and adolescents. Therefore, treatment for these patients should only be performed in paediatric major trauma centres.

Do Not Use Water Jets on Skin Hematoma.

Morel-Lavallée lesions are posttraumatic hemolymphatic collections related to shearing injury of variable mechanism (severe trauma or low-velocity crush injury), resulting in disruption of interfacial planes between subcutaneous soft tissue and muscle and perforating lymphatics and blood vessels. A 69-y-old woman, without medical history, was admitted to the emergency ward for important pain located from her behind to the anterior face of the thighs. Physical examination revealed large semirecent hematoma with a large soft fluctuant area with hypermobility of the skin and cutaneous hyperesthesia, spreading from her behind to the anterior face of her thigs. Her symptoms were typical of a Morel-Lavallée lesion. The ultrasound examination revealed hypoechoic heterogeneous compressible fluid containing fat debris with irregular margins and lobular shape, localized between subcutaneous fat and deep fascia, without flow on color Doppler, confirming the acute Morel-Lavallée lesion. After evacuation by needle puncture, the collection reappearance was probably due to hemolymphatic fluid corresponding to type 1 of the Mellado and Bencardino classification of Morel-Lavallée lesions. Patients and Physicians should be aware of the worsening effects of balneotherapy on skin hematoma to prevent dramatic extension of Morel-Lavallée lesions.

Is hyperbaric oxygen therapy indispensable for saving mutilated hand injuries?

Mutilated hand injuries are a profound challenge to the plastic surgeon, and such injuries often lead to limb loss and severe functional impairment. Hyperbaric oxygen therapy (HBOT) appears to counteract tissue hypoxia and stimulate acute wound healing. This study was performed to evaluate the efficacy of HBOT as an adjunctive therapy in patients with a mutilated hand injury. Between January 2006 and December 2014, 45 patients with a mutilated hand injury were enrolled. After reconstruction or revascularisation, patients underwent 120 minutes of HBOT with oxygen at 2·5 atmospheres absolute while breathing 100% oxygen. Outcomes such as amputee survival and surgery-related complications were recorded. The patients were 38 men and 7 women with average age of 37·2 years (range 18-62). The mean defect area was 131·5 cm2 (range 40-300). Most patients experienced a pure crush injury (53%). The average number of operations from the initial debridement to the first reconstruction was 3·8 (range 1-6). A total of 33 patients (73%) underwent replantation during the initial reconstruction. For flap coverage, most patients received a free flap using an anterolateral thigh flap (18 patients) or local flap using an abdomen/groin flap (nine patients). The average time from the first reconstruction or revascularisation to the first HBOT was 6·5 hours (range 2-12). The average number of HBOT sessions was 9·1 (range 6-14 sessions). The survival rate of the replanted fingers was 81%, and the survival rate of the palms was 100%. Most complications in the initial reconstruction involved partial loss of an avulsed flap, and most complications in the chronic stage (≥3 months) involved scar contracture. When combined with delicate microsurgery, early intervention using adjunctive HBOT was effective in preserving partially viable tissue and restoring hand function in patients with a mutilated hand injury.

Improving the care of patients with severe open fractures of the tibia: the effect of the introduction of Major Trauma Networks and national guidelines.

AIMS: The management of open lower limb fractures in the United Kingdom has evolved over the last ten years with the introduction of major trauma networks (MTNs), the publication of standards of care and the wide acceptance of a combined orthopaedic and plastic surgical approach to management. The aims of this study were to report recent changes in outcome of open tibial fractures following the implementation of these changes. PATIENTS AND METHODS: Data on all patients with an open tibial fracture presenting to a major trauma centre between 2011 and 2012 were collected prospectively. The treatment and outcomes of the 65 Gustilo Anderson Grade III B tibial fractures were compared with historical data from the same unit. RESULTS: The volume of cases, the proportion of patients directly admitted and undergoing first debridement in a major trauma centre all increased. The rate of limb salvage was maintained at 94% and a successful limb reconstruction rate of 98.5% was achieved. The rate of deep bone infection improved to 1.6% (one patient) in the follow-up period. CONCLUSION: The reasons for these improvements are multifactorial, but the major trauma network facilitating early presentation to the major trauma centre, senior orthopaedic and plastic surgical involvement at every stage and proactive microbiological management, may be important factors. TAKE HOME MESSAGE: This study demonstrates that a systemised trauma network combined with evidence based practice can lead to improvements in patient care.

Low energy KTP laser in oral soft tissues surgery: A 52 patients clinical study

Objectives: Since 1962 laser appliances have been used for soft tissues surgery of oral cavity with significant advantages compared to the traditional instruments: excellent bleeding control, possibility to avoid the use of suture, good patient compliance thanks to a decrease of intra- and post-operative discomfort and biostimulating effect. Unfortunately, the wavelengths so far used have been seen to cause, in association with an excellent ablation capacity, heat damage of the tissues that can decrease healing process and cause a greater discomfort to patients. The aim of this study was to evaluate the laser-assisted KTP laser surgery at low power in terms of characteristics of intervention and patients compliance. Study design: In this study, we describe the application of a new and recently introduced in dentistry wavelength, the KTP laser (532 nm), used with low power (1 Watt - CW), evaluating the time of interventions and, by a Numerical Rating Scale, the intra and postoperative pain. Results: KTP laser used at low power permits to obtain good pain control during operations that were carried out with only a topic an aesthetic (EMLA, Astratech), as shown in VAS tests. Good healing with limited or absent burning areas in treated portion of tissue. Conclusions: These preliminary study allows us to affirm that KTP laser with low parameters permits to perform oral surgery with good pain control and good wound healing. A greater number of clinical cases are however necessary to confirm the result obtained (AU)

[Further improvement of apparatuses for the hemostasis, processing and treatment of the infected wounds using high-temperature stream].

The bleeding stoppage and the wound sanitation constitute an important problem of modern surgery. There is information presented concerning the apparatuses elaboration for the bleeding stoppage, processing of the soft living tissues wounds, including the infected, during surgical operations conduction, using high-temperature stream of air. The data adduced about the apparatuses trial and preclinical investigations of the method, realized with their help, had confirmed a high efficacy of hemostasis and sanation effects as well as significant reduction of the wounds processing time.

Use of topical as only anesthetic for suturing a traumatic facial laceration.

A case is described where only topical anesthetic was used for suturing facial lacerations. The patient had sustained facial lacerations after a motor vehicle accident. After some initial treatment the patient refused injection anesthesia so only topical anesthetics lidocaine-prilocaine was used for one of the lacerations. Suturing was possible to perform with only topical anesthesia with good patient comfort.

[Lateral superior genicular flap combined with Tuihuang xiaozhong decoction for the treatment of soft tissue defects around the knee joint].

OBJECTIVE: To evaluate the early combination of Chinese and Western medicine for anti-inflammation and lateral superior genicular flap for the treatment of soft tissue defects around the knee joint. METHODS: From June 2004 to September 2008, 8 patients with soft tissue defects around the knee joint were treated with lateral superior genicular flap. Among the patients, 5 patients were male and 3 patients were female, ranging in age from 32 to 56 years, with an average of 35.2 years. The defected area ranged from 7.6 cm x 4.5 cm to 15.2 cm x 7.5 cm. The disease course ranged from 3 months to 3 years. Three patients had the defects at the posterior of the knee, 2 patients had the defects at the popliteal fossa, and 3 patients had the defects at the lateral side of the knee. At the early stage, all the patients were treated with Tuihuang Xiaozhong decoction and antibiotics for 3 to 5 days. RESULTS: All the flaps survived, and the knee function recovered. One patient had epidermis necrosis at the distal end of the flap of lateral side of the knee. CONCLUSION: The early combination of Chinese and Western medicine for anti-inflammation is a simple, easy to promote, and no special microsurgical instruments are needed.

Use of vacuum-assisted closure and a dermal regeneration template as an alternative to flap reconstruction in pediatric grade IIIB open lower-extremity injuries.

Severe degloving injuries to the pediatric lower extremity are difficult to treat, traditionally requiring local or free flaps for coverage. Combining vacuum-assisted closure techniques with a dermal regeneration template is proposed as a means for covering these difficult wounds. We retrospectively reviewed the charts of 7 consecutive patients (age range, 2-12 years) who underwent this treatment. All extremities healed without flap reconstruction or amputation. Mean follow-up was 24.4 months, and mean wound size was 196 cm2. There were 2 superficial graft complications, 1 nonunion successfully treated with bone grafting, 2 patients with subsequent bony deformity, and 1 patient who underwent subsequent soft-tissue procedures for equinus contracture. Use of vacuum-assisted closure and a dermal regeneration template has shown good results as a means of successfully managing grade IIIB injuries without performing complicated flap reconstructions.

Autologous platelets and leukocytes can improve healing of infected high-energy soft tissue injury.

Despite advances in surgical techniques and pharmacology, healing of injury-associated soft tissue defects is frequently complicated by infections, which often requires a secondary intervention. Cytokines are important mediators of healing. Application of autologous platelet-rich plasma enriched in growth factors and antimicrobial proteins, known also as platelet-leukocyte rich plasma (PLRP), represents a novel approach to the treatment of soft tissue and bone healing disturbances. This case is the first report on the application of PLRP in an infected high-energy soft tissue injury and shows that the volume and concentration of platelets and leukocytes is adequate to induce healing processes despite concurrent infection.

Surgical debridement of mineral pitch and nonviable penile tissue using water-jet power: a preliminary report.

OBJECTIVE: To report our experience of debriding genital wounds embedded with mineral pitch (MP) from asphalt, using a water jet-powered surgical tool, the Versajet Hydrosurgery System (VHS, Smith and Nephew, Key Largo, FL) before reconstruction. PATIENTS AND METHODS: We used the VHS for penile debridement in two patients. The first was 42-year-old Hispanic man involved in a truck-bike accident, who was dragged approximately 60 m after the collision. He presented with 25% body-surface abrasion impregnated with MP. The scrotal soft tissue had been lost and both testicles were exposed and ruptured, with no viable tissue. Moreover, the distal two-thirds of the penile urethra and the ventral glans were completely damaged and his penis entirely degloved. Several procedures were required for surgical debridement and reconstruction, including the skin grafting to 25% of his body surface. All surgical debridement was done with the VHS. A modified Thiersch-Duplay urethroplasty was used over a 16 F Foley catheter to reconstruct the missing urethra. The second patient was a 32-year-old man with no previous medical history, who presented with Fournier's gangrene after a penile abrasion following unprotected sexual intercourse. He required several surgical debridements. The VHS was applied to an 8 x 10 cm area, followed by a free-radial graft to the inferior epigastric. RESULTS: The clinical follow-up was 9 and 6 months, respectively; both patients had satisfactory granulation tissue and proper wound healing. Neither of the patients had infection after surgical debridement with the VHS, even when used in the case of Fournier's gangrene. CONCLUSION: The VHS appears to be effective for genital soft-tissue surgical debridement even when the tissue is impregnated with MP or infected, without causing any spread of infection. Larger series and a longer follow-up are needed to validate the effectiveness of the VHS in managing complex genital wounds.
