Background: The standard treatment of nasal bone fractures in pediatric patients is closed reduction. Conservative treatment is sometimes performed, but poses a risk of nasal deformity. The aim of this study was to evaluate the outcomes of bone remodeling in pediatric nasal fractures. Methods: Information was extracted from the medical records of patients under 12 years of age who received conservative treatment for a nasal bone fracture and underwent follow-up computed tomography (CT) examinations. The initial fracture and its outcomes over time were graded as excellent, good, or fair according to the malalignment, displacement, or irregularity of the fractured segments. The outcomes of remodeling were evaluated through changes in the grade of the fracture between initial and subsequent CT scans. Results: The review identified 16 patients between March 2015 and December 2019. Their mean age was 6.2 years, and the average follow-up period was 4.9 months. Three of the five patients with a plane I frontal impact showed improved outcomes of remodeling from good to excellent, and the remaining two patients, improved from fair to good. Eight of the 11 patients with plane I lateral impacts showed improved outcomes, from good to excellent, while one patient, improved from fair to good, one patient, improved from fair to excellent, and one patient showed no interval changes. Conclusion: In 15 of these 16 patients with non-severe fractures, the bony contour improved through remodeling, without surgical intervention. Therefore, we suggest that conservative treatment is a feasible option for mild pediatric nasal fractures.

Purpose: Pediatric burn still generates social problem leading to physical and mental sequelae for ages. We studied to help make a program for the prevention of pediatric burn. Methods: We analyzed retrospectically 2759 acute burn patients under the age of 15 years in recent 5years (January 2000 - December 2004). Results: 1553 males and 1226 females were investigated, with a male to female ratio of 1.25 : 1. The greatest number of burn patients were those with an age of 1 - 2 years(1435, 52%). Scalding burn was the most common cause of injury, which accounted for 1980 (71.8%) patients, followed by contact burns(286, 10.4%), flame burn(229, 8.3%), steam burn(141, 5.1%). Especially steam burn was the second cause of injury in the age under 1 year, while flame burn was the same in the age over 3 years. During recent 5 years, incidence of contact burn increased over twofold despite the others did not changed substantially. Variation of seasonal incidence is minimal and most of the patients(2545 cases, 92.2%) had burns of ${\leq}20%$ TBSA. The median hospital stay was 18.3 days, and the rate of operation was 35.4% with an high rate in electrical burn(70.6%), steam burn(68.8%), contact burn(65%). 27 patients died in this series, which yielded a mortality rate of 1%. Conclusion: We expect that these data will be used as a basis for prevention of pediatric burn.
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: Because of traffic accidents and many criminal violences, the incidence of facial trauma has been increasing not only in adults but also in children. We planed this study to introduce our experience about pediatric blow out fracture and provide more information. Methods: We made retrospective study in 76 children with blow out fracture from January 2001 to September 2005 by retrospective chart review including detailed preoperative and postoperative evaluations, age, sex, cause, symptom and sign, and their post-operative complications. Results: Among our patients, 69 were male and 7 were female. The ages ranged from 7 to 18 years, which shows the greatest incidence of blow out fracture. Physical violence(46%) was the most common cause in this group and was followed by vehicle accident(28%), and fall down accident(17%). Left side(64%) showed slightly more incidence than right side(36%), but there were no statistical importance. Ecchymosis(88%) was the most common symptom and followed by periorbital swelling(68%) and diplopia(30%). 30 patients was diagnosed with another facial bone fracture and nasal bone(51%) was the most common associated facial bone fracture. Fourty four Patients(60%) got an orbital wall reconstruction in 7 days after trauma. After the operation, only 3 patients(4%) suffered from diplopia postoperative 3 month, and resolved in 4 years. Conclusion: The incidence of blow out fracture in children has been increasing every year, and violence has become more important etiology of pediatric blow out fracture and public and private education institutions were the most common place that blow out fracture originated. Accurate diagnosis and careful treatment plans are important in pediatric blow out fracture.
Background Chloral hydrate (CH) is the primary agent most commonly used for pediatric sedation prior to diagnostic, therapeutic procedures. In the management of pediatric facial laceration, the initial dose of CH has to balance the need for adequate sedation against the need to minimize sedative complications. Methods A retrospective review of medical records of 834 children who visited our emergency room for facial lacerations from August 2010 to September 2012 was conducted. They were divided into six groups on the basis of the initial dose of CH administered. Further, each group was compared with the standard group (70 to ${\leq}80mg/kg$) with respect to sedation success, augmentation dose, failed sedation, time to procedure, and time of stay. Results With respect to the complication rate, only group 1 (range, 40 to ${\leq}50mg/kg$) showed a significantly lower complication rate. In the case of all the other variables considered, there were no significant differences among any of the groups. Conclusions An initial CH dose of $48{\pm}2mg/kg$ does not negatively affect the success rate of sedation or the need for additional sedative during the primary closure of facial lacerations in pediatric patients. Further, lower doses reduce the incidences of adverse effects and do not delay procedure readiness. Therefore, $48{\pm}2mg/kg$ of CH can be considered the optimal initial dose for pediatric sedation.
Purpose: Reconstruction of soft tissue defect using tissue expander can provide better flap which is more similar to surrounding tissue in color, skin texture and hair compared to other methods. Many pediatric patients need reconstruction of soft tissue defect because of giant congenital nevi, congenital or acquired malformations and burn scars. Reconstruction using tissue expander is adequate to minimize dysmorphism in these patients. We intended to assess outcomes of using tissue expander in pediatric patients by retrospective study. Methods: Total cases were 168 of pediatric patients who received soft tissue reconstruction using tissue expander by the same surgeon from February, 1982 to May, 2009. All patients who received soft tissue reconstruction were under 10 years old. Mean age was 4.3 years old, the youngest 13 months, the oldest 8 years. Eightynine cases were male and 79 cases were female. Most common cause was giant hairy nevi (67 cases, 39.9%), secondary cause was burn scar/scar contracture (61 cases, 36.3%). Trunk (38 cases, 22.6%) was most common anatomical location. Results: Soft tissue defects were successfully covered using tissue expander in 149 cases (88.7%) without major complications. There was infection on 8 cases (4.7%) and we treated by adequate antibiotics in these cases. There were tissue expander folding or valve displacement on 5 cases (3%). Conclusion: Usage of tissue expander is useful on pediatric patients because tissue expansion is rapid on children and there are less secondary contractures on operation site than full thickness skin graft. Because of psychological stress due to tissue expander, operation should be performed before school age.

Purpose: Owing to improvement of microscope, microsurgery implements, and microsuture, finger replantation has shown much development. With high success rate of microsurgery in children, positive results have been reported ever from distal amputation. Here, we report the patients demographics, methods, and results of the microsurgery performed in children in our hospital for the last 8 years. Methods: From the medical records of 21 patients who had given the treatment in our hospital from January 2000 to December 2007, we analyzed patients' sex, age, operative method, and complication retrospectively. Results: The number of male patients was twice as many as female, where most patients belong to the ages of five to ten years. Operative methods performed in this study included end - to - end anastomosis of artery and vein, vein graft, and epineurial suture. As a result, 19 out of 21 cases were successfully accomplished, and four of them went through the debridement of necrotic tissue due to the partial necrosis of the lesion. A one - year follow - up observation was done after surgery and most of them were almost fully recovered like in their previous state. Conclusion: The success rate of finger replantaion in children is continuously improving despite the difficulty of vessel anastomotic procedure, rehabilitation treatment and management after surgery. We report the satisfactory results of pediatric finger replantation technically and aesthetically.

Epignathus is a rare congenital orofacial teratoma that arises from the sphenoid region of the palate or the pharynx. It occurs in approximately 1:35,000 to 1:200,000 live births representing 2% to 9% of all teratomas. We present the case of a newborn of 39.4 weeks of gestation with a tumor that occupied the entire oral cavity. The patient was delivered by cesarean section. Oral resection was managed by pediatric surgery. Plastic surgery used virtual 3-dimensional models to establish the extension, and depth of the tumor. Bloc resection and reconstruction of the epignathus were performed. The mass was diagnosed as a mature teratoma associated with cleft lip and palate, nasoethmoidal meningocele that conditions hypertelorism, and a pseudomacrostoma. Tridimensional technology was applied to plan the surgical intervention. It contributed to a better understanding of the relationships between the tumor and the adjacent structures. This optimized the surgical approach and outcome.

Background: Bone grafts can provide an optimal environment for permanent tooth to erupt and enhance the stability of the alveolar maxilla. Although autologous bone is an optimal source for osteogenesis, its inevitable donor site morbidity has led to active research on bone substitutes. This study was designed to evaluate the safety and feasibility of using biphasic calcium phosphate (BCP; Osteon) as a bone substitute in dogs. Methods: Bilateral third and fourth premolars of four 15-week-old mongrel dogs were used. All teeth were extracted except the third premolar of the right mandible, which was used as a control. After extraction of the premolars, each dog was administered BCP (Osteon), demineralized bone matrix (DBM; DBX), and no graft in the hollow sockets of the right fourth premolar, left fourth premolar, and left third premolar, respectively. Radiographs were taken at 2-week intervals to check for tooth eruption. After 8 weeks, each dog was sacrificed, and tooth and bone biopsies were performed to check for the presence of tooth and bone substitute particle remnants. Results: Four weeks after the operation, permanent tooth eruptions had started at all the extraction sites in each dog. Eight weeks after the operation, all teeth had normally erupted, and histological examination revealed BCP particles at the right fourth premolar. Conclusion: In all four dogs, no delay in the eruption of the teeth or shape disfigurement of permanent teeth was observed on gross inspection and radiologic evaluation. On histological examination, most of the BCP and DBM were replaced by new bone. Bone substitutes can be used as graft materials in patients with alveolar clefts.
