RESUMO
BACKGROUND: Treatment protocols for macrodactyly have not been elucidated due to its rarity and variety of clinical manifestations. This study aims to share our long-term clinical results of epiphysiodesis in children with macrodactyly. METHODS: A retrospective chart review was performed for 17 patients with isolated macrodactyly treated with epiphysiodesis over 20 years. Length and width of each phalanx in both the affected finger and the corresponding unaffected finger in the contralateral hand were measured. Results were presented in ratios of the affected to unaffected side for each phalanx. Measuring of length and width of phalanx was performed preoperatively and postoperatively at 6, 12, and 24 months, and the last follow-up session. Postoperative satisfaction scoring was done with visual analogue scale. RESULTS: The mean follow-up period was 7 years and 2 months. In the proximal phalanx, length ratio significantly decreased compared with preoperative state at after more than 24 months, in the middle phalanx after 6 months, in the distal phalanx after 12 months. When classified by the growth patterns, the progressive type showed significant decrease in length ratio at after 6 months, and the static type after 12 months. Patients were overall satisfied with the results. CONCLUSION: Epiphysiodesis effectively regulated longitudinal growth with different degree of control for different phalanges in the long-term follow-up.

BACKGROUND: Acral lentiginous melanoma (ALM) is a rare subtype of malignant melanoma that usually involves the weight-bearing plantar area. Plantar defect reconstruction has traditionally been performed with skin grafts or free flaps. This study examined the efficacy and safety of a medial plantar artery perforator flap (MPAPF) for plantar defect reconstruction after wide excision of an ALM. METHOD: Twenty-five patients who underwent reconstruction with a MPAPF between 2011 and 2021 were enrolled in this study. The defects were classified into 6 plantar zones. Demographic and clinical data were retrospectively analyzed. RESULTS: Reconstruction with medial plantar fasciocutaneous island flaps was performed in all cases, except for 4 patients who had lesions in forefoot, which required free medial plantar flaps. Defects in lateral and posterior heel were more likely to present with venous congestion and require longer healing times and revision surgery (P < 0.05). The average follow-up period was 49 months. Four and 5 patients developed local recurrence and distant metastasis, respectively. Four cases of hyperkeratosis and paresthesia were documented, but there were no cases of ulceration or wound dehiscence. None of the cases required secondary debulking procedures. CONCLUSIONS: The MPAPF is safe and effective for plantar defect reconstruction among patients with ALM. Meticulous dissection and adequate tunneling are needed, particularly for defects in the lateral and posterior heel, to minimize flap congestion and revision operations.

Giant lipomas are rarely found in the head and neck region. A 67-year-old male patient presented with a massive ventral swelling of his neck extending from the lower margin of the mandible to the clavicle. The mass had slowly grown over 20 years without causing any symptoms, except for considerable psychological stress because of the disfiguration of the patient's profile appearance. Contrast magnetic resonance imaging suggested a lipomatous soft tissue lesion. The surgically removed tumor measured 32 × 20 × 4âcm. Surgery was completed without any intraoperative complications or injury to the critical structures of the neck. The patient was satisfied with the cosmetic result of the operation, and histopathological examination confirmed a lipoma.

In hand and upper extremity replantation surgery, simultaneous free flap reconstruction restores the physiologic circulation to the amputated part, ensuring its survival, and promotes wound healing through anatomic restoration. Especially in digit replantation, an arterialized venous flap serves to reconstruct both vessel and soft tissue defects simultaneously. Delayed free flap reconstruction aims to enhance both functional improvement and cosmetic acceptance in a successfully replanted part using flaps that include functioning muscle, bone, joint, nerve, and soft tissue.

BACKGROUND: Traditional skin grafts for syndactyly often cause color mismatches and unsightly donor sites, whereas no-skin-graft methods leave noticeable dorsal hand scars. This study presents plantar full-thickness skin graft (FTSG) from the weight-bearing midline area for syndactyly repair, a novel approach not previously reported in the literature. METHODS: The study included three groups of patients with congenital syndactyly of the hand who underwent primary operations with plantar FTSG (n=70), groin FTSG (n=20), and no-skin-graft techniques (n=22). Postoperative outcomes were evaluated by an assessment panel, and guardians' satisfaction scores were measured. Color similarity between the graft and surrounding skin was assessed using a three-dimensional color space. RESULTS: The plantar FTSG group demonstrated a significantly higher likelihood of receiving an 'excellent' rating compared to the groin FTSG group, with an odds ratio of 6.30 (p<0.001). Color difference analysis showed that plantar FTSG more closely matched surrounding skin color than groin FTSG (6.33 vs. 22.57, p<0.001). Guardians reported greater satisfaction with outcomes on the hand in the plantar FTSG group compared to the groin FTSG and no-skin-graft groups (7.16 vs. 5.05 and 4.36, p<0.001). Satisfaction with donor sites was also significantly higher in the plantar FTSG group than in the groin FTSG group (8.23 vs. 6.30, p<0.001). CONCLUSION: Correction of congenital hand syndactyly using midline plantar FTSG from the weight-bearing area can reduce scarring on the hand dorsum, ensure superior color similarity with surrounding skin, and offer inconspicuous donor sites compared to no-skin-graft or groin FTSG techniques.
RESUMO
Reconstruction of traumatic nail bed defects in the digits is a frequently encountered procedure, yet often presents many challenges. In such scenarios, staged procedures may be required with significant limitations in shape and increased donor site morbidity, particularly when multiple defects are present. In this study, we introduce a simple method for the reconstruction of nail bed defects using an acellular dermal matrix (ADM). The study involved 19 digits with nail defects, which underwent reconstruction using an ADM graft. The surgical procedure was performed on all patients on the day of injury, after which they were promptly discharged. The dimensions of the defect ranged from 0.5â ×â 0.5 cm to a maximum of 2â ×â 3 cm (average, 0.9â ×â 1.4 cm). Final examinations were performed at postoperative 5-11 months (average, 6.6 months). All ADM grafts were successfully taken. Nail growth was observed at an average of 4 months after surgery in the treated finger. The surgical results were retrospectively evaluated using the Zook criteria. Outcomes were "excellent" in 11 patients (57.9%), "very good" in five patients (26.3%), "good" in two patients (10.5%), and "fair" in one patient (5.2%). The expanded application of ADM explored in this study illustrates a straightforward method for the reconstruction of traumatic nail bed defects, providing effective results in a single stage without incurring donor site morbidity.
RESUMO
Refractory chylous ascites can cause significant nutritional and immunologic morbidity, but no clear treatment has been established. This article introduces a case of a 22-year-old female patient with an underlying lymphatic anomaly who presented with refractory chylous ascites after laparoscopic adnexectomy for ovarian teratoma which aggravated after thoracic duct embolization. Ascites (>3,000 mL/d) had to be drained via a percutaneous catheter to relieve abdominal distention and consequent dyspnea, leading to significant cachexia and weight loss. Two sessions of hybrid lymphovenous anastomosis (LVA) surgery with intraoperative mesenteric lymphangiography guidance were performed to decompress the lymphatics. The first LVA was done between inferior mesenteric vein and left para-aortic enlarged lymphatics in a side-to-side manner. The daily drainage of chylous ascites significantly decreased to 130 mL/day immediately following surgery but increased 6 days later. An additional LVA was performed between right ovarian vein and enlarged lymphatics in aortocaval area in side-to-side and end-to-side manner. The chylous ascites resolved subsequently without any complications, and the patient was discharged after 2 weeks. The patient regained weight without ascites recurrence after 22 months of follow-up. This case shares a successful experience of treating refractory chylous ascites with lymphatic anomaly through LVA, reversing the patient's life-threatening weight loss. LVA was applied with a multidisciplinary approach using intraoperative mesenteric lipiodol, and results showed the possibility of expanding its use to challenging problems in the intraperitoneal cavity.
RESUMO
BACKGROUND: The goals of heel reconstruction are functional and aesthetic. Primarily due to the particular function of the heel in supporting the entire weight of the body while standing, these goals can be achieved by providing the heel with a durable and weight-bearing surface with adequate contour. Various methods such as skin graft, fasciocutaneous, and musculocutaneous local flaps have been reported for reconstructing this area. This retrospective study introduces different kinds of free flaps for heel reconstruction. METHODS: Between July 2010 and September 2016, 13 patients underwent soft tissue reconstruction of the heel with anterolateral thigh flap, lateral arm flap, superficial circumflex iliac artery perforator flap, and temporalis muscle flap. Immediate and delayed postoperative results of the surgery were evaluated with satisfaction assessed subjectively among the patients. RESULTS: There were 8 cases of anterolateral thigh flap (61.5%), 2 cases of lateral arm flap (15.3%), 2 cases of superficial circumflex iliac artery perforator flap (15.3%), and 1 case of temporalis muscle flap (7.6%). The mean duration of surgery was 261.69 (range, 114-442) minutes and the average length of absolute immobilization was 8.38 (range, 6-11) days. All flaps survived with 3 cases of minor revision due to partial necrosis, wound dehiscence, and bulky flap. There were no morbidities among donors. Satisfactory aesthetic and functional results were observed among all the patients. CONCLUSION: This article suggests that various free flaps can be considered as reliable options in heel reconstruction, resulting in acceptable functional and aesthetic outcomes.

Anatomies of the vascular and lymphatic systems have been vital research topics in reconstructive surgery. Harvey was a pioneer who provided the earliest descriptions of the cutaneous vasculature in the 17th century. The concept of vascular territories of the skin was first described by Manchot. The radiographic injection method in cadavers was developed by Salman, who defined more than 80 vascular territories. The arterial system has been thoroughly investigated with the development of regional and free flaps. The concept of axial and random pattern flaps was introduced by McGregor and Morgan. Manchot's vascular territories were refined by Taylor and Palmer as the angiosome concept. Detailed information about the venous circulation is essential for reconstructive surgeries. The concept of intrinsic and extrinsic venocutaneous vascular systems was introduced by Nakajima and led to the development of the venoadipofascial flap. The importance of venous augmentation in flap survival was emphasized by Chang. The lymphatic system was discovered much later than the arterial and venous systems. Aselli was credited for discovering the lacteal vessels in the 17th century; mercury was popularly used as a contrast agent to distinguish lymphatic vessels for the next three centuries. A radiographic method in cadavers was developed by Suami. Lymphatic imaging devices are constantly upgrading, and photoacoustic imaging was recently introduced for three-dimensional visualization of architecture of superficial layers of the lymphatic and venous systems.
RESUMO
BACKGROUND: Acellular dermal matrices (ADMs) have become an essential material for implant-based breast reconstruction. No previous studies have evaluated the effects of sterility of ADM under conditions of radiation. This study compared sterile (irradiated) and aseptic (non-irradiated) ADMs to determine which would better endure radiotherapy. METHODS: Eighteen male Balb/C mice were assigned to the control group with no irradiation (group 1) or one of two other groups with a radiation intensity of 10 Gy (group 2) or 20 Gy (group 3). Both sterile and aseptic ADMs were inserted into the back of each mouse. The residual volume of the ADM (measured using three-dimensional photography), cell incorporation, α-smooth muscle actin expression, and connective tissue growth factor expression were evaluated. The thickness and CD3 expression of the skin were measured 4 and 8 weeks after radiation. RESULTS: In groups 2 and 3, irradiated ADMs had a significantly larger residual volume than the non-irradiated ADMs after 8 weeks (P<0.05). No significant differences were found in cell incorporation and the amount of fibrosis between irradiated and non-irradiated ADMs. The skin was significantly thicker in the non-irradiated ADMs than in the irradiated ADMs in group 3 (P<0.05). CD3 staining showed significantly fewer inflammatory cells in the skin of irradiated ADMs than in non-irradiated ADMs in all three groups after 4 and 8 weeks (P<0.05). CONCLUSIONS: Under radiation exposure, irradiated ADMs were more durable, with less volume decrease and less deposition of collagen fibers and inflammatory reactions in the skin than in non-irradiated ADMs.
RESUMO
BACKGROUND: In postaxial polysyndactyly of the foot, the choice of which toe to excise is controversial. It is often treated by resection of the fifth toe to save the lateral neurovascular bundles of the sixth toe. However, the sixth toe is often short and laterally deviated, which may require wedge osteotomy, potentially shortening the phalanx and compromising circulation. This study outlines an individualized method to spare the length and axis of the fifth toe in polysyndactyly with a short and deviated sixth toe. METHODS: We retrospectively analyzed 38 patients who underwent surgery between 2006 and 2019. The fifth toe was spared in 18 cases, and the sixth toe in 20 cases. The ratios of the forefoot width, angle difference, and toe length were compared between the affected and unaffected sides postoperatively. Complications and subjective judgments on cosmetic results were recorded and compared. RESULTS: No significant between-group differences were observed for sex, age at surgery, or the follow-up period. The forefoot width ratio did not significantly differ between the groups. However, the angle difference and toe length ratios showed significantly better results in the fifth toe-spared group than in the sixth toe-spared group (P<0.05 and P<0.01, respectively). There were no cases of impaired circulation, and subjective evaluations revealed satisfactory results in the fifth toe-spared group. CONCLUSIONS: In cases with short and deviated sixth toes, sparing the fifth toe is an effective method of cosmetic treatment. The surgical results were satisfactory, with an improved appearance and no residual deformities.
