Traumatic defects are mostly accompanied by hard and soft tissue loss. This report describes the surgical and prosthetic treatment of a patient with post-traumatic mandibular defect. A split-thickness skin graft was performed prior to implant placement and prefabricated acrylic stent was placed to hold the graft in place. The esthetic and functional demands of the patient were fulfilled by implant-supported screw-retained fixed prosthesis using CAD-CAM technology.
Purpose: In extensive deep burn of the lower limb, due to less amount of soft tissue, bone is easily exposed. When it happens, natural healing or reconstruction with skin graft only is not easy. Local flap is difficult to success, because adjacent skins are burnt or skin grafted tissues. Muscle flap or free flap are also limited and has high failure rate due to deep tissue damage. The authors acquired good outcome by performing one - stage operation on bone exposed soft tissue defect with AlloDerm$^{(R)}$(LifeCell, USA), an acellular dermal matrix producted from cadaveric skin. Methods: We studied 14 bone exposed soft tissue defect patients from March 2002 to March 2009. Average age, sex, cause of burn, location of wound, duration of admission period, and postoperative complications were studied. We removed bony cortex with burring, until conforming pinpoint bone bleeding. Then rehydrated AlloDerm$^{(R)}$(25 / 1000 inches, meshed type) was applicated on wound, and thin split thickness(6 ~ 8 / 1000 inches) skin graft was done at the immediately same operative time. Results: Average age of patients was 53.6 years(25 years ~ 80 years, SD = 16.8), and 13 patients were male(male : female = 13 : 1). Flame burn was the largest number. (Flame burn 6, electric burn 3, contact burn 4, and scalding burn 1). Tibia(8) was the most affected site. (tibia 8, toe 4, malleolus 1, and metatarsal bone 1). Thin STSC with AlloDerm$^{(R)}$ took without additional surgery in 12 of 14 patients. Partial graft loss was shown on four cases. Two cases were small in size under $1{\times}1cm$, easily healed with simple dressing, and other two cases needed additional surgery. But in case of additional surgery, granulation tissue has easily formed, and simple patch graft on AlloDerm$^{(R)}$ was enough. Average duration of admission period of patients without additional surgery was 15 days(13 ~ 19 days). Conclusion: AlloDerm$^{(R)}$ and thin split thickness skin graft give us an advantage in short surgery time and less limitations in donor site than flap surgery. Postoperative scar is less than in conventional skin graft because of more firm restoration of dermal structure with AlloDerm$^{(R)}$. We propose that AlloDerm$^{(R)}$ and thin split thickness skin graft could be a solution to bone exposured soft tissue defects in extensive deep burned patients on lower extremities, especially when adjacent tissue cannot be used for flap due to extensive burn.
Purpose: Anatomically, the foot is provided with insufficient blood supply and is relatively vulnerable to venous congestion compared to other parts of the body. Soft tissue defects are more difficult to manage and palliative treatments can cause hyperkeratosis or ulcer formation, which subsequently requires repeated surgeries. For weight bearing area such as the heel, not only is it important to provide wound coverage but also to restore the protective senses. In these cases, application of flaps for hind foot reconstruction is widely recognized as an effective treatment. In this study, we report the cases of soft tissue reconstruction for which various types of flaps were used to produce good results in both functional and cosmetic aspects. Methods: Data from 37 cases of hind foot operation utilizing flaps performed between from June 2000 to June 2008 were analyzed. Results: Burn related factors were the most common cause of defects, accounting for 19 cases. In addition, chronic ulceration was responsible for 8 cases and so forth. Types of flaps used for the operations, listed in descending order are radial forearm free flap (18), medial plantar island flap (6), rotation flap (5), sural island flap (3), anterolateral thigh free flap (2), lattisimus dorsi muscular flap (2), and contra lateral medial plantar free flap (1). 37 cases were successful, but 8 cases required skin graft due to partial necrosis in small areas. Conclusion : Hind foot reconstruction surgeries that utilize flaps are advantageous in protecting the internal structure, restoring functions, and achieving proper contour aesthetically. Generally, medial plantar skin is preferred because of the anatomical characteristics of the foot (e.g. fibrous septa, soft tissue for cushion). However alternative methods must be applied for defects larger than medial plantar skin and cases in which injuries exist in the flap donor / recipient site (scars in the vicinity of the wound, combined vascular injury). We used various types of flaps including radial forearm neurosensory free flap in order to reconstruct hind foot defects, and report good results in both functional and cosmetic aspects.
The cervical flap, comprising skin, fascia, and platysma muscle, has significant application in the head and neck region after radical ablative surgery for cancer of the oral cavity. The flap may be used for reconstruction of the cheek, floor of the mouth, and lateral side of the tongue. This flap minimizes donor morbidity by use of cervical operation wound and flap size available is adequate for most oral defects and the procedure is relatively simple and time-saving. However the flap is not applicable in patients where there are large tissue defects and metastasis is suspected. We have used the cervical flap for its rapid, simple, and effective closure of oral defects after cancer ablation and found it is very useful for the reconstruction of relatively small oral defects.
The soft tissue defects including the Achilles tendon are complex and very difficult to reconstruct. Recently, several free composite flaps including the tendon have been used to reconstruct large defects in this area in an one-stage effort. Our case presents a patient reconstructed with free composite dorsalis pedis flap along with the extensor digitorum longus and superficial peroneal nerve for extensive defects of the Achilles tendon and surrounding soft tissue. A 36-year-old-man sustained an open injury to the Achilles tendon. He was referred to our department with gross infection of the wound and complete rupture of the tendon associated with loss of skin following reduction of distal tibial bone fracture. After extensive debridement, $6{\times}8cm$ of skin loss and 8cm of tendon defect was noted. Corresponding to the size of the defect, the composite dorsalis pedis flap was raised as a neurosensory unit including the extensor digitorum longus to provide tendon repair and sensate skin for an one-stage reconstruction. One tendon slip was sutured to the soleus musculotendinous portion, the other two were sutured to the gastrocnemius musculotendinous portion with 2-0 Prolene. The superficial peroneal nerve was then coaptated to the medial sural cutaneous nerve. The anterior tibial artery and vein were anastomosed to the posterior tibial artery and accompanying vein in an end to end fashion. After 12 months of follow-up, 5 degrees of dorsiflexion due to the checkrein deformity and 58 degrees of plantar flexion was achieved. The patient was able to walk without crutches. Twopoint discrimination and moving two-point discrimination were more than 1mm at the transferred flap site. The donor site healed uneventfully. Of the various free composite flaps for the Achilles tendon reconstruction when skin coverage is also needed, we recommand the composite dorsalis pedis flap. The advantages such as to control infection, adequate restoration of ankle contour for normal foot wear, transfer of the long tendinous portion, and protective sensation makes this flap our first choice for reconstruction of soft tissue defect including the Achilles tendon.
Purpose: The venous flap is used as an alternative method to the standard free flap for the management of small and thin soft tissue defects. Especially, the venous flap has advantages of being thin, easy harvest and various donor sites, as well as it having lower morbidity. Yet their clinical applications have been limited by their unstable postoperative course and also by their complications such as partial necrosis. The aim of this study is to extend the clinical indications of venous flaps with using various methods. Methods: From May 2005 to March 2006, total of 19 patients(21 cases) underwent various venous flaps for soft tissue defects as a result of trauma(15 cases), facial skin cancer(3 cases), chronic ulcer(1 case) and surgical wound for congenital anomaly(2 cases). The arterialized venous free flap were applied in 18 cases, the pure venous free flap was applied in 1 case and the pure venous pedicled flap were applied in 2 cases. Among them, two flow-through arterialized venous free flaps were applied that used the great saphenous vein to reconstructed major arteries as well as the injured skin and soft tissues in the arm. All the flap were harvested from the volar wrist(11 cases), dorsum of foot(5 cases), thenar(2 cases), and medial thigh(3 cases). Results: The sizes of the flap ranged from $0.75cm^2$ to $264cm^2$(mean size: $40.06cm^2$). The follow-up period ranged from two to twelve months. In the majority of cases, we obtained satisfying results, which was the excellent reconstruction of skin and soft tissue defects and especially in the case of limb salvage, replantation and cancer reconstruction. However, there were 5 cases of partial necrosis and 2 cases of complete failure. The donor sites were closed primarily in 7 cases and wound closure with skin graft were in 14 cases. Conclusion: We conclude that the venous flap will not only be useful for reconstruction of small defect in the hand and foot, but also be useful for various other clinical indications.

Background Repair of facial laceration in the emergency department can pose a number of difficulties. Children can be uncooperative, but adults can also be if they have sustained head trauma or are intoxicated. Leukosan SkinLink consists of topical adhesive and adhesive tape that can be applied easily to long or tense wounds. In this study, the authors compared conventional suturing with Leukosan SkinLink for facial laceration patients in the emergency department. Methods The prospective study was carried out from March 2013 to September 2013 with linear facial laceration patients visiting the emergency department. Exclusion criteria were open fractures, joint injuries, skin defects, hairy skin, and mucosa. The author used Leukosan SkinLink for skin closure in the experimental group and used conventional suturing in the control group. The scar evaluation using the Patient and Observer Scar Assessment Scale (POSAS) along with satisfaction scores, procedure times, and complications were compared. Results A total of 77 patients (30 in the control group and 47 in the experimental group) participated and underwent follow-up for 6 months postoperatively. The scar assessment using the POSAS and the satisfaction score in both groups were similar. The average procedure time in the experimental group was shorter. In the control group, there were four cases of wound dehiscence, two of infection, and one of skin necrosis, whereas four cases of wound dehiscence and one allergic reaction occurred in the experimental group. Conclusions With a simple application technique, Leukosan SkinLink is a new effective method for facial laceration repair especially useful for children and uncooperative adults.
Purpose: We performed vastus lateralis (VL) muslce or myocutaneous flap for close of the trochanteric skin defect usually happened in paraplegia and report our 6 cases. Materials and Methods: Between March 2004 and August 2005 we performed 4 cases of VL muscule flap with skin graft and 2 cases of VL myocutaneous flap for close of the trochanteric skin defect in 6 paraplegia patients. There were 5 men and 1 woman and mean age was 52.2 years and mean diameters of skin defect was $8.3{\times}8.3\;cm$. The mean follow up period was 18 months. The survival of flap, complications, healing time and patient's satisfaction were evaluated. Results: All flaps were survived except 1 case of margin necrosis. In 2 cases, blood-serous discharges were continued after operation which might be due to dead space and treated with $2{\sim}3$ times debridement and delayed close. Mean time to heal the skin defect was 7.6 weeks. No infection and recurrence in follow up periods. Cosmetic results judged by patients are that 3 cases are good and 3 cases are fair. Conclusion: VL muscle and myocutaneous flap is good treatment method among the numerous methods in treatment-failed cases of trochanteric skin defects of paraplegia patients. This surgical procedure is simple, constant blood supply, good pliability, cosmetic results and also appliable to other skin defect of pelvis girdle like sacrum and ischium.
Objective : Spinal dysraphism defects span wide spectrum. Wound dehiscence is a common postoperative complication, and is a challenge in the current management of cerebrospinal fluid (CSF) leaks and wound healing. The purpose of this study is to evaluate the risks of CSF-related morbidity in the surgical treatment of spinal dysraphism. Methods : Ten patients with spinal dysraphism were included in this retrospective study. The median age of the cohort was 4.8 months. To assess the risk of CSF morbidity, we measured the skin lesion area and the percentage of the skin lesion area relative to the back surface for each patient. We then analyzed the relationship between morbidity and the measured skin lesion area or related factors. Results : The overall median skin lesion area was 36.2 $cm^2$ (n=10). The percentage of the skin lesion area relative to the back surface ranged from 0.6% to 18.1%. During surgical reconstruction, 4 patients required subsequent operations to repair CSF morbidity. The comparison of the mean area of skin lesions between the CSF morbidity group and the non-CSF morbidity group was statistically significant (average volume skin lesion of $64.4{\pm}32.5cm^2$ versus $27.7{\pm}27.8cm^2$, p<0.05). CSF morbidity tended to occur either when the skin lesion area was up to 44.2 $cm^2$ or there was preexisting fibrosis before revision with an accompanying broad-based dural defect. Conclusion : Measuring the lesion area, including the skin, dura, and related surgical parameters, offers useful information for predicting wound challenges and selecting appropriate reconstructive surgery methods.

Background: Cases of simultaneous multiple skin cancers in a single patient have become more common. Due to the multiplicity of lesions, reconstruction in such cases is more difficult than after a single lesion is removed. This study presents a series of patients with multiple facial skin cancers, with an analysis of the surgical removal, reconstruction process, and the results observed during follow-up. Methods: We reviewed 12 patients diagnosed with multiple skin cancers on the face between November 2004 and March 2016. The patients' medical records were retrospectively reviewed to identify the type of skin cancer, the site of onset, methods of surgical removal and reconstruction, complications, and recurrence during follow-up. Results: Nine patients had a single type of cancer occurring as multiple lesions, while three patients had different skin cancer types that occurred together. A total of 30 cancer sites were observed in the 12 patients. The most common cancer site was the nose. Thirteen defects were reconstructed with a flap, while 18 were reconstructed with skin grafting. The only complication was one case of recurrence of basal cell carcinoma. Conclusion: Multiple skin cancers are removed by performing Mohs micrographic surgery or wide excision, resulting in multiple defect sites. The authors emphasize the importance of thoroughly evaluating local lesions surrounding the initially-identified lesions or on other sites when reconstructing a large defect which can not be covered by primary closure. Furthermore, satisfactory results can be obtained by using various methods simultaneously regarding the condition of individual patients, the defect site and size, and the surgeon's preference.
