الوصف: Background Surgical scars subjected to excessive tension tend to widen and become hypertrophic due to strong mechanical stretching forces. In this study, we evaluated the clinical outcomes of combined intraoperative and postoperative long-term tension reduction techniques for the revision of scars subjected to excessive tension. Methods In total, 64 cases (62 patients) underwent scar revision and were followed for 6 months or more. The long-term tension reduction technique included intraoperative subcutaneous fascial and deep dermal closure using nonabsorbable nylon sutures and postoperative long-term skin taping for 3 to 8 months. The final scars were objectively evaluated using our Linear Scar Evaluation Scale (LiSES, 0-10 scale), which consisted of five categories: width, height, color, texture, and overall appearance. Results All 64 cases healed successfully, without early postoperative complications such as infection or dehiscence. The follow-up period ranged from 6 months to 6 years. The LiSES scores ranged from 5 to 10 (mean: 8.2). Fifty-one cases (79.6%) received a score of 8 to 10, which was assessed as “very good” by the evaluator. Two cases with a score of 5 (3%) showed partial hypertrophic scars at the last follow-up visit. All patients were highly satisfied with their final outcomes, including the two patients who experienced partial hypertrophic scars. Conclusions A combination of intraoperative and postoperative long-term tension reduction techniques can achieve the goal of long-term dermal support and satisfactory aesthetic outcomes for scar revision in areas subjected to excessive tension.

الوصف: Abstract This study aimed to (1) evaluate the preoperative Hb cut-off value for transfusion after unilateral and bilateral staged (1 week apart) TKAs, respectively, and (2) determine whether cause of preoperative anemia can affect transfusion rate after TKA. A total of 951 patients who underwent TKA (unilateral: 605, bilateral staged: 346) from 2016 to 2019 were reviewed retrospectively. Patient demographics, comorbidities, preoperative Hb level, surgery types, and cause of anemia were evaluated as possible risk factors. The cut-off values for preoperative Hb level to reduce transfusion after TKA were evaluated in each surgery type. Preoperative Hb level, surgery type, and cardiac disease were identified as the risk factors for transfusion after TKA, and preoperative Hb levels of 11.8 (AUC 0.88) and 12.8 (AUC 0.76) were the cut-off values for transfusion after unilateral and staged bilateral TKAs, respectively. Although transfusion rate was higher in anemia with iron deficiency (ID) group than anemia without ID group, preoperative Hb level was also lower in anemia with ID group than anemia without ID group. Single use of preoperative Hb level with different cut-offs depending on the surgery types can be useful indicator for preoperative optimization regardless of cause of anemia.

الوصف: Giant congenital melanocytic nevi are rare, and it is recommended to excise due to the possibility of malignancy. Although tissue expansion for nevus removal involves multiple stages, the advantages of tissue expansion are known well. We report a case of a giant congenital melanocytic nevus of the upper extremity that extended from the elbow to the shoulder. This case was challenging due to the circumferential nature of the lesion, the lack of healthy skin, the need to ensure minimal scarring, and the desire to impact the patient’s daily life as little as possible. The use of a pre-expanded thoracodorsal artery perforator (TDAP) flap and re-expansion of the transferred flap were considered most appropriate. A pre-expanded pedicled TDAP flap can be transferred to any anatomical region with its versatility. The re-expansion of the transferred flap ensures the health of the skin and minimizes donor site scarring. Here, we achieved the optimal outcome through the combined use of a pre-expanded pedicled TDAP flap and sequential re-expansion of the transferred flap in the treatment of a giant nevus of the upper extremity.

الوصف: Background: Cultured allogenic keratinocyte (CAK) and epidermal growth factor (EGF) are commonly used biological treatments for partial-thickness burn wounds. A comparative study was conducted on whether the combination therapy of CAK and EGF promotes partial-thickness burn wound healing.Methods: From January 2020 to March 2021, 73 patients who visited the hospital with partial-thickness burns were enrolled in the study. Patients were treated with CAK (Kaloderm) (n=20), EGF (Easyef) (n=17), and CAK+EGF (n=24). Wound healing rate, time to heal, factors affecting wound healing (age, sex, underlying disease, mode of injury, location of injury, initial wound size), and scarring were comparatively analyzed.Results: The wound healing rate for 20 days was 85% (17/20) in the CAK group, 88% (15/17) in the EGF group, and 92% (22/24) in the CAK+EGF group. The average healing time was 11.0±6.0 days, with the CAK group taking 12.6±5.5 days, EGF group taking 11.5±6.0 days, and CAK+EGF group taking 9.0±6.3 days. The patients who received CAK+EGF treatment had higher hazard than the patients without CAK+EGF treatment (hazard ratio, 2.078; 95% confidence interval, 1.021–4.228). Smaller wound size

الوصف: Background: Conservative treatment of deep dermal or full-thickness skin defects often results in hypertrophic scars or contractures; thus, compressive therapy has been used after wound closure to prevent or treat scar deformities. However, wound contraction begins in the early proliferative phase and peaks after 2 weeks. We therefore attempted early compression therapy as a means of conservative treatment of deep-skin defects and evaluated its clinical outcomes. Methods: In 21 cases of deep skin defects (19 patients), early compressive therapy was started the second week after injury. Saline-moistened gauze or foam dressings were placed on open wounds, and foam dressings or silastic plates were used after epithelialization. The compression materials included elastic bandages, adhesive tapes, or garments. The final scars were assessed using the Vancouver Scar Scale (VSS) and satisfaction degree.Results: Defect size ranged from 1.4×0.7 to 5×5 cm. The duration of compression was 4 to 12 months. The follow-up periods were 4 to 61 months. Mild scar hypertrophy or contracture occurred in 15 cases and subsided after application of topical corticosteroid or triamcinolone injection. The final scar shapes were linear (n=12), geographic (n=5), and oval (n=4). The mean VSS score was 2.3. The degrees of satisfaction were excellent (61.9%) and good (23.8%). In most cases, aesthetically and functionally satisfactory outcomes without pathologic scars were demonstrated with minimal scar size, high scar quality, and high satisfaction.Conclusion: Early compression therapy might be a good option to prevent pathologic scars in the conservative treatment of deep skin defects.

الوصف: Purpose: In general orthopedic surgery, the use of prophylactic antibiotics to prevent infection is recommended to be administered within 24 hours. However, there was no analysis on the incidence of surgical site infection according to the duration of use of prophylactic antibiotics for upper extremity fractures. This study aims to derive the appropriate prophylactic antibiotic using time by analyzing the incidence of infection according to the time of prophylactic antibiotic use in distal radius fractures.Methods: We retrospectively analyzed patients who used prophylactic antibiotics among patients who underwent open reduction and internal fixation for distal radius fractures from April 2018 to May 2021. The time of use of prophylactic antibiotics was classified into the 1-day group used, from 1 hour before surgery to 24 hours after the first administration, and the long-term group, continuously administered until discharge after surgery. Demographic characteristics, infection rate, C-reactive protein, risk factors for surgical site infection, and bone union were compared between the two groups.Results: A total of 168 patients were included in the study, 73 in the 1-day group and 95 in the long-term group. Superficial infection occurred in seven patients in the 1-day group and nine in the long-term group, and there was no statistically significant difference in the incidence rates of the two groups (p=0.980). Conclusion: The use of prophylactic antibiotics for 24 hours does not show a significant increase in the infection rate compared to the case of continuous use during open reduction and internal fixation of distal radius fractures.

الوصف: Titanium micro-mesh implants are widely used in orbital wall reconstructions because they have several advantageous characteristics. However, the rough and irregular marginal spurs of the cut edges of the titanium mesh sheet impede the efficacious and minimally traumatic insertion of the implant, because these spurs may catch or hook the orbital soft tissue, skin, or conjunctiva during the insertion procedure. In order to prevent this problem, we developed an easy method of inserting a titanium micro-mesh, in which it is wrapped with the aseptic transparent plastic film that is used to pack surgical instruments or is attached to one side of the inner suture package. Fifty-four patients underwent orbital wall reconstruction using a transconjunctival or transcutaneous approach. The wrapped implant was easily inserted without catching or injuring the orbital soft tissue, skin, or conjunctiva. In most cases, the implant was inserted in one attempt. Postoperative computed tomographic scans showed excellent placement of the titanium micro-mesh and adequate anatomic reconstruction of the orbital walls. This wrapping insertion method may be useful for making the insertion of titanium micro-mesh implants in the reconstruction of orbital wall fractures easier and less traumatic.

الوصف: Stickler syndrome is a genetic disorder of connective tissue. One of the major symptoms associated with this disorder is an oro-facial malformation, which may cause a submucous cleft or a complete cleft of the hard palate. A 32-year-old man diagnosed with Stickler syndrome and a submucosal cleft palate (SMCP) visited our hospital with a chief complaint of excessive daytime sleepiness. The patient was diagnosed with severe obstructive sleep apnea (OSA), and administration of a polysomnography test revealed an apnea-hypopnea index (AHI) of 30.9 events/hour (h). Auto-titrating continuous positive airway pressure was initiated to control the OSA symptoms and subsequently the patient showed some improvement. However, due to continuous velopharyngeal insufficiency symptoms, intravelar veloplasty was performed. Three months after surgery, the AHI had decreased to 12.4 events/h. Recent studies have described a greater risk for OSA in individuals with cleft palate, than in the general population. The present case demonstrates surgical success in a patient with OSA and SMCP, suggesting that palatal surgery may be considered an optional surgical treatment for OSA patients with SMCP.
