RESUMO
BACKGROUND: This paper discusses the treatment protocol for patients with frostbite. METHODS: We performed a retrospective analysis of a series of 17 patients with second- and higher-degree frostbite who had been treated at our medical institution between 2010 and 2012. RESULTS: Our clinical series of patients (n=17) included 13 men and four women, whose mean age was 42.4+/-11.6 years (range, 22-67 years). The sites of injury include the foot in six patients (35.3%), the hand in six patients (35.3%) and the facial region in five patients (29.4%). Seven patients with second-degree frostbite were completely cured with only conservative treatment during a mean period of 12.7+/-3.3 days (range, 8-16 days). Of the five patients with third-degree frostbite, two underwent skin grafting following debridement, and the remaining three achieved a complete cure with conservative treatment during a mean period of 35+/-4.3 days (range, 29-39 days). Five patients with fourth-degree frostbite were treated with surgical procedures including amputation. CONCLUSIONS: With the appropriate conservative management in the early stage of onset, surgeons should decide on surgery after waiting for a sufficient period of time until the demarcation of the wound. Continuous management of patients is also needed to achieve functional recovery after a complete cure has been achieved. This should also be accompanied by patient education for the avoidance of re-exposure to cold environments.

BACKGROUND: An area of the skull exposed by burn injury has been covered by various methods including local flap, skin graft, or free flap surgery. Each method has disadvantages, such as postoperative alopecia or donor site morbidities. Due to the risk of osteomyelitis in the injured skull during the expansion period, tissue expansion was excluded from primary reconstruction. However, successful primary reconstruction was possible in burned skull by tissue expansion. METHODS: From January 2000 to 2011, tissue expansion surgery was performed on 10 patients who had sustained electrical burn injuries. In the 3 initial cases, removal of the injured part of the skull and a bone graft was performed. In the latter 7 cases, the injured skull tissue was preserved and covered with a scalp flap directly to obtain natural bone healing and bone remodeling. RESULTS: The mean age of patients was 49.9+/-12.2 years, with 8 male and 2 female. The size of the burn wound was an average of 119.6+/-36.7 cm2. The mean expansion duration was 65.5+/-5.6 days, and the inflation volume was an average of 615+/-197.6 mL. Mean defect size was 122.2+/-34.9 cm2. The complications including infection, hematoma, and the exposure of the expander were observed in 4 cases. Nonetheless, only 1 case required revision. CONCLUSIONS: Successful coverage was performed by tissue expansion surgery in burned skull primarily and no secondary reconstruction was needed. Although the risks of osteomyelitis during the expansion period were present, constant coverage of the injured skull and active wound treatment helped successful primary reconstruction of burned skull by tissue expansion.

BACKGROUND: Pediatric hand burns are a difficult problem because they lead to serious hand deformities with functional impairment due to rapid growth during childhood. Therefore, adequate management is required beginning in the acute stage. Our study aims to establish surgical guidelines for a primary full-thickness skin graft (FTSG) in pediatric hand burns, based on long-term observation periods and existing studies. METHODS: From January 2000 to May 2011, 210 patients underwent primary FTSG. We retrospectively studied the clinical course and treatment outcomes based on the patients' medical records. The patients' demographics, age, sex, injury site of the fingers, presence of web space involvement, the incidence of postoperative late deformities, and the duration of revision were critically analyzed. RESULTS: The mean age of the patients was 24.4 months (range, 8 to 94 months), consisting of 141 males and 69 females. The overall observation period was 6.9 years (range, 1 to 11 years) on average. At the time of the burn, 56 cases were to a single finger, 73 to two fingers, 45 to three fingers, and 22 to more than three. Among these cases, 70 were burns that included a web space (33.3%). During the observation, 25 cases underwent corrective operations with an average period of 40.6 months. CONCLUSIONS: In the volar area, primary full-thickness skin grafting can be a good indication for an isolated injured finger, excluding the web spaces, and injuries of less than three fingers including the web spaces. Also, in the dorsal area, full-thickness skin grafting can be a good indication. However, if the donor site is insufficient and the wound is large, split-thickness skin grafting can be considered.

BACKGROUND: Deep burns of the elbow lead to soft tissue necrosis and infection, with exposure of deep structures. Adequate wound coverage of this area requires thin, pliable, and durable tissue, while optimal functional recovery requires early coverage and functional rehabilitation. We have found 3 types of island flaps that provide reliable coverage for the elbow. METHODS: A retrospective study was performed on all patients who underwent flap coverage of an elbow defect at our hospital. The patients' data including age, sex, cause of injury, wound dimensions, timing of flap coverage, postoperative elbow motion, and complications were investigated. RESULTS: Between 2001 and 2012, 16 patients were treated at our hospital. The mean age was 53.3 years. Three kinds of flaps were performed: 9 latissimus dorsi flaps, 4 lateral arm flaps, and 4 radial forearm flaps. The average defect size was 183.5 cm2 (range, 28 to 670 cm2). Wound coverage was performed at mean duration of 45.9 days (range, 14 to 91 days). The mean postoperative active elbow flexion was 98degrees (range, 85degrees to 115degrees). Partial flap failure occurred in 1 latissimus dorsi flap. Minor complications included partial flap loss (11.8%), hematoma (23.5%), seroma (35.3%), and wound infection (5.9%). CONCLUSIONS: Flap selection for elbow reconstruction is determined by the defect size and the extent of the adjacent tissue injury. Elbow reconstruction using an island flap is a single-staged, reliable, and relatively simple procedure that permits initiation of early rehabilitation, thereby improving a patient's functional outcome.

PURPOSE: As a central feature of the face, the nose has considerable significance in appearance and expression. Reconstruction of full thickness defects of the nasal ala has always been a challenge because of the 3-dimensional structure. For reconstruction of post burn defects of ala, skin graft, local or pedicled flap and composite graft are optionally available. We have reconstructed the ala defects using adiposocutaneous graft and observed the outcome. METHODS: From March 2003 to December 2010, 19 cases in 11 patients with scar contracture and defect on ala portion were performed operation using adiposocutaneous graft. As a donor site, we used the inguinal crease and posterior auricular area and the donor site was primarily closed. We made incision through the superior rim of ala and released fully. A graft is applied to recipient site with larger size than recipient volume. RESULTS: The mean age of the patient was 38.6 years (16~51), males are seven patients and females are four patients. The operation was performed bilaterally in 5 patients and unilaterally in 6 patients. Composite grafts were harvested from inguinal area in 13 cases and posterior auricular area in 6 cases. In one case, we did 4 times of operation to get enough volume. All the grafts were well taken. The mean size of the graft was 3.63 cm2. CONCLUSION: For reconstruction of post burn defects of ala, it's not easy to use local flap or pedicled flap because of hardness and fibrosis of surrounding tissue. So, we choose adiposocutaneous graft for ala deformity reconstruction, got satisfactory outcome in color matching and texture.

PURPOSE: The objective of this study is to analyze the epidemiological characteristics of pediatric burn patients and to determine the targets for a pediatric burn prevention program. METHODS: A retrospective review of all medical records of acute pediatric burn patients (age < 15 years old) admitted to our hospital between January 2005 and December 2009 was performed. RESULTS: 1472 males and 1323 females were investigated, with a male to female ratio of 1.11 : 1. The greatest number of burn patients were those with an age of 1~2 years (1,463, 52.3%). Scalding burn was the most common cause of injury, which accounted for 2183 (78.1%) patients, followed by contact burns (10.5%), flame burn (4.9%), steam burn (3.6%). Especially steam burn was the second cause of injury in the age under 1 year, while flame burn was the second cause of injury in the age over 7 years. During recent 5 years, incidence of flame burn, steam burn, electrical burn gradually decreased. Variation of seasonal incidence is minimal and most of the patients (2,716 cases, 97.2%) had burns less than 20% TBSA (Total body surface area). The median hospital stay was 18.79 days, and the rate of operation was 28.6% with a high rate in electrical burn (76.2%), flame burn (50.0%), steam burn (46.1%). 6 patients died in this series, which yielded a mortality rate of 0.2%. CONCLUSION: Prevention efforts should reflect recent study results. Focused prevention program and campaign to make people aware of risk factors and their avoidance is required to reduce the number of burn accidents in children.

PURPOSE: Patients with serious burns are prone to chondritis due to lack of soft tissue in the auricle, which can cause severe defects in the auricular morphology. In addition, skin damage occurs frequently in the vicinity of post-burn wounds, presenting difficulties in reconstruction surgery. An auricular reconstruction has functional and cosmetic significance. The aim of this study is to develop appropriate reconstruction methods for auricular defects. METHODS: Thirty seven patients, who were treated for auricular defects from 2005 to 2009, were enrolled in this study. A local flap, multiple regional flaps and cartilage framework with or without a temporal fascial flap were applied in reconstruction surgery according to the location of the auricular defect. RESULTS: The age of the subjects ranged from 11 to 56. Some subjects had defects that cover more than half of the helical rim with most exhibiting post-burn scars in the vicinity, for whom a multiple regional flap was used. A single use of a tubed flap was sufficient for subjects with defects that covered less than half of the helical rim. A regional flap was also used for reconstruction in subjects with defects covering both the helical rim and antehelix. CONCLUSION: Achieving satisfactory results from the skin flaps and skin grafts for post-burn auricular defects in both functional and cosmetic aspects is a difficult task. Therefore, selecting an appropriate surgical method through proper diagnosis of the auricular defect and the state of the available skin in the vicinity is essential.

PURPOSE: Spontaneous tendon rupture of finger is defined the rupture of tendon without any intrinsic or extrinsic pathological processes in finger. Spontaneous flexor tendon ruptures are rare. Burn affects not only skin but also muscle and tendon according to the depth. Particularly, burn in hand badly affects movement of finger. Thus, We report the case of spontaneous flexor tendon rupture of finger that happened after burn. METHODS: We studied a 42 year old male presented with third degree electrical burn at the palm of the right hand. And then, Terudermis(R) was applied on 23rd day after burn and split thickness skin graft was applied on 37th day after burn. After operation, there were no special symptoms for some period. But, on 74th day after burn, while providing physical therapy to finger, he could not flex his thumb of the hand with popping sound and edema. So we performed US and MRI scan, finally diagnosed complete tear on FPL tendon of the right hand which was in flexor tendon injury zone IV. We harvested donor from Palmaris longus and tendon graft was applied. RESULTS: After operation, graft was well taken without other problem. And after applying splint, 4th day after tendon graft, active finger extension was done with passive flexion achieved using a rubber band attached to the finger tip. 4 weeks after the operation, splint was removed and the patient gently started active exercise. CONCLUSION: Spontaneous rupture of flexor tendon is rare and moreover, there was no case report of rupture after burns so far. We are now reporting that we early diagnosed the spontaneous flexor tendon rupture of the burned hand and functionally corrected by tendon graft.

PURPOSE: Recently there are upgrowing public interest of cosmetics and anti-aging and also public request of chemical peel and its complications. It is a strong chemical agent and can occur severe chemical burn. METHODS: This research surveyed from August 2008 to March 2010 by 3 patients who had gotten chemical burn by phenol peel. We investigated age, sex, site, size and treatment. RESULTS: The average age of cases was 43 years old. They were all female. Damaged area was all on face. Wound size was 3.3% in average. Wound depth was deep second degree in 2 cases and mid second degree in 1 case. In one case, ectropion on both lower eyelids was occurred by scar contracture. We did release and thick split thickness skin graft to resolve ectropion. To other milder cases, we managed conservatively. CONCLUSION: People who had gotten chemical burn by phenol therapy didn't get proper therapy instantly. We suggest that phenol peel must be performed very carefully and by professional and experienced surgeon.

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.

PURPOSE: The purpose of this study is to evaluate the effectiveness and validity of the wound dressing using heterogenic type I collagen dressing (Collaheal(R)). METHODS: From January 2010 to April 2010, 46 burn patients with deep second degree or third degree burn wound were treated with Collaheal(R). And we followed up the patients to assess the treatment result with Vancouver scar scale after 6 months. RESULTS: Of the 46 patients, 42 patients had deep second degree burn only and 4 patients had deep second degree burn with third degree burn. It took 18.5 days to re-epithelialize for patients with deep second degree burn and 40.5 days for third degree burn wound. After 6 months, follow-up was performed to assess the wound result. We can observe that 24 patients had mild scar and 5 patients had moderate scar and 2 patients had severe scar. The severity of scar increased as the re-epithelialization period increased. CONCLUSION: It took 18.5 days to re-epithelialize the deep second degree burn wound with collagen dressing. And the long term result was good. Type I collagen dressing can be used for treatment option for the patients with deep second degree burn wound and the patients with small third degree burn wound who cannot be operated.

PURPOSE: Massive pediatric burns are subject to progress to wound infection and sepsis at early stage. Early escharectomy and allograft made it safer to treat the pediatric burn patients from this morbidity. The purpose of this study is to analyze the impact of the early escharectomy and temporary wound coverage with allograft on massive pediatric burns. METHODS: From January 1999 to August 2010, 55 pediatric burn patients aged 1 to 10 years whose total burn surface area was over 20% were reviewed. Among them, only 19 patients underwent escharectomy (Pediatric escharectomy group, PEG) and 36 patients underwent escharectomy and allograft (Pediatric allograft group, PAG) And 533 allograft patients (Allograft group, AG) aged over 10 whose total burn surface area were over 20% were reviewed to compare with the pediatric allograft patients. RESULTS: PAG was operated earlier (mean 3.6 days from injury) than PEG (mean 5.9 days). The mortality of PAG (8.3%) was lower than the mortality of PEG (31.6%) significantly. And the PAG were operated earlier than AG (mean 5.8 days from injury). But the difference of mortality was not significant statistically between PAG and AG. CONCLUSION: Early escharectomy and allograft is safe and effective treatment procedure for massive pediatric burn patients by preventing wound sepsis.

PURPOSE: The wound of a patient who has chronic venous insufficiency is easy to recur. Also they develop a complication even after the conservative therapy or skin graft. We have to diagnose the venous stasis ulcer correctly and remove the cause to improve the effectiveness of treatment. We operated endoscopic perforating vein ligation and splitt thickness skin graft on a patient with venous stasis ulceration on right leg. METHODS: A 26 year old male patient who had a scalding burn on his right leg in July 2005 checked into our hospital in March 2008. Even though he got three operations-the split thickness skin graft-at different clinics, the wound did not heal. The size of the wound was 12 by 8 cm2 and granulation with edema and fibrosis had been formed. We kept observation on many collateral vessels and perforating vein through venogram and doppler sonography and firmly get to know that the wound came with chronic venous insufficiency. After a debridement and an application of VAC(r) for two weeks, the condition of granulation got better. So we proceeded with the operation using subfascial endoscopic perforating surgery and split thickness skin graft. RESULTS: Through the venogram after the operation, we found out that the collateral vessels had been reduced compared to the previous condition and the widened perforating vein disappeared. During a follow up of 6 months, the patient did not develop recurrent stasis ulcer and postoperative complications. CONCLUSION: Subfascial endoscopic perforator ligation is a relatively simple technique with a low complication rate and recurrence rate. Split thickness skin graft with subfascial endoscopic perforator surgery can be a valuable method for treating severe venous stasis ulcers.

PURPOSE: Wide scars occurring on the lower face and neck cause both functional and esthetic problems. Consequently, we can use skin grafts, pedicled flaps, free flaps, and tissue expansion for the reconstruction of this area. Compared with other reconstruction techniques, tissue expansion is advantageous in that it enables the maintenance of a color and texture similar to that of the adjacent tissue. However, the conventional method of tissue expansion has been reported to lead to an unnatural cervicomental angle and to the deformity of adjacent structures. We have therefore made efforts to prevent these problems through the use of several operative procedures. METHODS: Forty-one patients with lower facial and cervical scars underwent tissue expansion. The tissue expansion was performed using a rectangular-shaped Nagosil(R) tissue expansion device. On insertion of the tissue expander, the intermediate area of superficial fat layer was dissected and then the tissue expander was inserted to make a flap that was as thin as possible. In advancement of the flap, a capsule formed by the tissue expander was used for the interrupted fixed suture of the flap to the fascia of the platysma muscle of the neck. This procedure was performed multiple times and also performed between the flap and the periosteum of the mandible, such that the tension was removed during the suture of the flap margin. Finally, the patients were fitted with a Jobst(R) facial garment in order to stabilize the operation site at least twelve months. RESULTS: The most prevalent location of the scar was the cheek(15 cases), followed by the chin in 14 cases and the neck in 12 cases. The mean size of scar was 55.7+/- 39.4cm2. CONCLUSION: Using our procedures, we have experienced no significant deformities and have also achieved a more natural cervicomental angle in the patients.

PURPOSE: The face is very important body area. So, for burns on the face, early wound healing is important of all. Since B.C.1500, Greeks started using phototherapy for wound healing. Although phototherapy has been studied a long time, the mechanism and result of researches have not been clearly defined. So, the authors will evaluate the effectiveness of the phototherapy, spectrum of 633 nm and 830 nm, and the effectiveness in second degree facial burn. METHODS: We studied 30 burn patients with second degree burn wounds with symptoms of edema, discharge, and redness whom admitted from August 2006 to May 2008. Wound healing of phototherapy was compared to that with hydro-gel dressing. We evaluated each groups by the time it took for wound to epithelize, swelling disappearance, the amount of exudates, hospital days. Satisfaction question surveyed by patients ranging from 0 to 5 scales with 0 being the lowest and 5 being the highest. RESULTS: The duration of epithelization was 10+/-2.3 days in cases with phototherapy. Setting the factor's point becoming 1, the duration of cases with hydro-gel dressings was redness 5+/-2.2 days, discharge 6+/-1.8 days, and the average admission days were 11+/-1.6 days. The group with phototherapy was evaluated superior to the control group in satisfaction index by 30%. CONCLUSION: Simple hydro-gel dressing on facial burn is a routine job. Considering the fact that face is the most prominent sight-catching point, we should try to heal the wound as soon as possible. Phototherapy is the choice that we can use to shorten the duration of redness, the time it takes to epithelize and increase satisfaction index. So if possible, when got a burn on face, authors recommend the phototherapy.

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 succeed, 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 in four cases. Two cases were small in size under 1x1cm, 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 of short surgery time and less limitations in donor site than flap surgery. Postoperative scar is smaller compared to in conventional skin graft because of firmer 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: Most burn scar contractures are curable with skin grafts, but free flaps may be needed in some cases. Due to the adjacent tissue scarring, local flap is rarely used, and thus we may consider free flap which gives us more options than local flap. However, inappropriate performance of free flap may lead to unsatisfactory results despite technical complexity and enormous amount of effort. The author will discuss the points we should consider when using free flaps in treating burn scar contractures METHODS: We surveyed patients who underwent free flaps to correct burn scar contractures from 2000 to 2007. We divided patients into two groups. The first group was those in which free flaps were inevitable due to exposure of deep structures such as bones and tendons. The second group was those in which free flap was used to minimize scar contracture and to achieve aesthetic result. RESULTS: We performed 44 free flap on 42 patients. All of the flaps were taken well except one case of partial necrosis and wound dehiscence. Forearm free flap was the most common with 21 cases. Most of the cases(28 cases) in which free flaps were inevitable were on the wrist and lower limbs. These were cases of soft tissue defect due to wide and extensive burns. Free flaps were done in 16 cases to minimize scar contracture and to obtain aesthetic outcome, recipient sites were mostly face and upper extremities. CONCLUSION: When using free flaps for correction of burn scar contractures, proper release and full resurfacing of the contracture should be carried out in advance. If inadequate free flap is performed, secondary correction is more challenging than in skin grafts. In order to optimize the result of reconstruction, flap thickness, size and scar of the recipient site should be considered, then we can achieve natural shape, and minimize additional correction.

PURPOSE: The latissimus dorsi flap and the serratus anterior flap have been used as combined flaps to reconstruct extensive defects. Because these two muscles are usually supplied by the subscapular- thoracodorsal vessels, the two flaps can be based on vascular pedicle that is long and anatomically reliable. In this case, we reported that serratus anterior possessed an anomalous arterial supply totally independent from the subscapular pedicle while raising combined latissimus dorsi and serratus anterior flap. METHODS: A 35-year-old male with extensive soft tissue defect in the left perineum and thigh visited. Muscle defects of the medial thigh were observed, and femoral nerve and vessels were exposed. Combined latissimus dorsi and serratus anterior free flap was raised to reconstruct defect. On raising flaps, artery supplying the serratus anterior muscle originated from the axillary artery directly, was lying on the undersurface of the serratus anterior muscle. RESULTS: Because two flap pedicles had no communication and latissimus dorsi muscle was large enough to cover soft tissue defect, we transferred only latissimus dorsi free flap with 1:3 meshed skin graft. Patient had limb salvage and satisfactory functional outcome. CONCLUSION: There are many variations of arterial pedicles of flaps. However, most of these variations remain within known anatomical consistence, thus is an indicator in planning the dissection of the vessels. According to documents, arterial pedicle to the serratus muscle not originated from the thoracodorsal artery is rarely reported, and in most of these cases, the arteries are originated from the subscapular artery. Thus pedicle directly originated from the axillary artery to serratus muscle is a very rare variation in its vascular anatomy.
