In Fibrous dysplasia(FD) of the jaws, the majority of cases can await the cessation of growth before surgical intervention, and it seems prudent to delay surgery whenever possible until growth has ceased. In craniofacial FD, however, the dangers of dystopia, dystopia and loss of vision may require early surgery to prevent or control cranio-orbital complications. Delaying surgery in those circumstances may be significantly detrimental to such patients. Conservative surgical management of FD is widely practised and we advocate an extension to this conservative treatment by combining surgical recontouring with appropriate osteotomies if indicated, to achieve an optimal esthetic and functional results in craniofacial FD. One case will be presented to illustrate the feasiblility of such combined treatment, to report the uneventful healing of osteotomies in the FD of the jaws, and to demonstrate the use of titanium miniplate fixation in dysplastic bone. The other case had expansile disease of the left facial and fronto-temporal bones and osteolytic change left mandible. This patient complained of severe spontaneous bleeding of left mandibular premolar area and it was suspected as central hemangioma of the left mandible and craniofacial FD. Angiogram disclosed generalized dilation of the external carotid artery and its branches, especially terminal branches of the left facial and inferior alveolar arteries. But no specific abnormalities, such as A-V shunt, venous lake, or early venous drainage, was seen. So it was diagnosed craniofacial FD with hypercellularity and generalized bony recontouring was performed via coronal and transoral approaches.

Background Facial fractures are infrequent in children and adolescents and have different clinical features from those in adults. The low incidence in children and adolescents reflects the flexibility and underdevelopment of their facial skeletons, as well as their more protected environments. Only a few reports have reviewed such patients in Korea. The authors performed a retrospective study to analyze the characteristics of facial fractures in the Korean pediatric population. Methods We conducted a retrospective review on a series of 741 patients, aged <18 years, with facial fractures who had been treated at our hospital between 2006 and 2010. The following parameters were evaluated: age, sex, cause, location and type of fractures, associated injuries, treatment and complications. Results A total of 741 consecutive patients met the inclusion criteria. The ratio of boys to girls was 5.7:1. Facial fractures most commonly occurred in patients between 13 and 15 years of age (36.3%). The most common causes of injury was violence. The nasal fracture was the most common type of fracture (69%) and the blowout fracture was the second most common (20%). Associated injuries occurred in 156 patients (21%). Conclusions The incidence of pediatric facial fractures caused by violence is high in Korea. Our results show that as age increases, etiological factors and fracture patterns gradually shift towards those found in adults. This study provides an overview of facial fractures in these age groups that helps illustrate the trends and characteristics of the fractures and may be helpful in further evaluation and management.

Background Polydactyly of the foot is one of the most frequent anomalies of the limbs. However, most classification systems are based solely on morphology and tend to be inaccurate and less relevant to surgical methods and results. The purpose of this study is to present our new classification of polydactyly of the foot, which can serve as a predictor of treatment and prognosis. Methods To find a correlation between the various morphologic traits of polydactyly of the foot and the treatment plan and outcomes, we reviewed 532 cases of polydactyly of the foot in 431 patients treated in our hospital, expanding on our previous study that described polydactyly based on the importance of metatarsal bone status and varus deformity. The records of patients were evaluated and compared with previous studies at other centers. Results Unsatisfactory results were seen in 36 cases, which included 5 cases of incomplete separation due to syndactylism, 23 cases of axis deviation, and 8 cases of remnants of extradigit metatarsal bones. The locus of the polydactyly, or the digit which was involved, did not seem to affect the final postoperative outcomes in our study. Three factors-syndactylism, axis deviation, and metatarsal extension-are the major factors related to treatment strategy and prognosis. Therefore, we developed a new classification system using three characters (S, A, M) followed by three groups (0, 1, 2), to describe the complexity of polydactyly of the foot, such as $S_1A_2M_2$. Conclusions Our new classification could provide a communicable description to help determine the surgical plan and predict outcomes.

The relation of endocrine in the western medicine and zangfu-organ functions in Korean medicine, related to growth disturbance, was studied and derived the following results. 1. The hormone most related to growth disturbance is, directly secreted from the anterior pituitary or is stimulated and secreted in the target grands, growth hormone, thyroid, adrenocortical hormone, gonadial hormone and is insulin secreted from $\beta$ cell of langerhans' slands of pancreas. 2. the pituitary has the most close relation with the kidney in the five zang-organ. Because the kidney is innate origin(先天之本) and promotes qi and blood(生化氣血), stores the essence of life(藏精), dominates the bones(主骨) and promotes the marrow(生骨髓). Especially it is connected with brain(通於腦). 3. In the children growth, the endocrine action in the pituitary has the most close relation with the kidney, As in the reports of the brain and spinal cord, bone, store essence of life, sexual maturation and decline(kidney-qi, sexual functions of both sexes(天癸)) etc, and cause of cretinism, dwarf in the main subject. 4. Somatomedin is the most important factor of the growth factors, IGF in another word. The unification of IGF and secretion is controlled firstly according to growth hormone, however is very closely related to the nutrition status in the non-hormonic causes. Also, it is affected very much by the insulin. 5. Insulin is one of the important hormone related to the growth and is secreted from the pancreas. Pancreas belongs to the functional system of spleen in oriental medicine, thus the growth disturbance, occurred due to error in insulin secretion and nutrition(in another words, the lack of postnatal essential substance from food-stuff(水穀精氣)), is closely related to the spleen. 6. From the results driven above, the hormone action of endocrine and problem in secretion, related to the growth disturbance, must be focused on the differentiation of symptoms and signs of the kidney and the spleen in oriental medicine.

Purpose: Heterotopic calcification is the abnormal deposition of calcium salts in tissues other than bone and enamel, and it occurs in the form of dystrophic calcification or metastatic calcification. This deposition can occur under many conditions, but in some rare cases, it may develop in burns and nonhealed scars. It is difficult to treat the combination of heterotopic calcification and ulceration in scar tissues by using conservative therapy and to determine the margin of excision in such cases. Our study proposes the use of intraoperative C-arm-guided mapping of lesions with heterotopic calcification, and adequate excision of ulcers in chronic scars where heterotopic calcification is also observed. Methods: This study included 2 patients and was conducted from January 2010 to July 2010. The first patient was a 63-year-old woman who presented with atypical calcium deposits and chronic ulceration in the lower one-third region of the right leg. The second patient was a 38-year-old man who presented with a nonhealing ulcer that had developed on the right leg 3 months earlier he had a history of 40% scalding burns on the entire body. Surgery is the most reliable method for treating heterotopic calcification therefore, both patients were treated using intraoperative C-arm-guided marginal mapping of heterotopic calcification, followed by release of contracture, and eventually split-thickness skin grafting. Results: Plain radiographs of the leg showed spotty radiopaque areas in the hard part of the scar well superficial to the underlying bones. Histopathological analysis revealed multiple foci of calcified deposits, increased fibrosis, and inflammation in the scar tissue. Surgery-related complications were not observed. Conclusion: C-arm guided excision of calcified scars and the release of contracture can cure nonhealing ulcers and may therefore prevent recalcification.

This study was undertaken to investigate the effect of cingulate cortical ablation upon gastric ulceration, and the pathway through which cingulate cortex exerts the effect. 56 female rats were divided equally into cingulate (cingulate cortical ablation), cingulate-vagal (cingulate cortical ablation and vagotomy), normal control and vagal (vagotomy) groups. Cingulate cortex was ablated through a slit-shaped opening (1 mm in width, 13 mm in length) which was made symmetrically on both sides of, and parallel to, the sagittal suture by removing a bone flap from parietal and frontal bones on each side. Vagus nerves on both sides were transected around the distal end of the esophagus. In the normal control animals, surgical intervention ended with scalp incision. All rats were kept without restraint or food deprivation for 3 weeks after surgery. The stomach of each rat was inflated with 7 ml of physiological saline and then removed under deep anesthesia. The mucosal surface was examined under dissecting microscope for the location, shape and number of ulcers, and then enlarged photograph $(4{\times})$was taken. The incidence of ulcer in each group was counted and the number of ulceration as well as the total area of glandular mucosa were measured on the photograph. Results obtained were as follows: 1. The mean number of ulcer per stomach and the total area of ulcer exprssed as permillage of the total area of glandular mucosa were significantly higher in the cingulate group than the cingulate-vagal, the normal control and the vagal groups. There was no difference among the latter three groups. 2. The incidence of ulcer in the cingulate group was significantly higher than that in the .normal control group and was also higher, though not significantly, than those in the cingulate-vagal and the vagal groups. There was no difference among the normal control, the cingulate-vagal and the vagal groups. It is inferred from the above results that the cingulate cortex exerts an inhibitory influence upon gastric ulceration and that this influence is mediated by controlling the vagal activity.

Purpose: The authors applied Bilhaut-Cloquet procedure to Wassel type III and IV duplicated thumb, which was limited to patients with Wassel type I, II. This procedure was applied in order to improve the growth potential, range of joint motion, joint stability and cosmetic outcome. Methods: Sixteen patients received Bilhaut-Cloquet procedures to correct duplicated thumbs from May, 2005 to December, 2010. Seven patients were Wassel type III, nine patients were type IV. This procedure was applied not only to balanced type, but also unbalanced type or convergent type. Five patients were balanced type and eleven patients were unbalanced type. Convergent type of Wassel type IV was three. Sex ratio was the same, mean age at the operation was 20.1 months old (8~52 months old). Angular deformity, joint stability and range of joint motion and cosmetic outcome were considered together and estimated in Tada score. Also, postoperative subjective satisfaction score of the parents was evaluated by a 100-points scale. Results: Mean subjective satisfaction scored 75 points at 28 months after the operation. Radiologic study showed bony union of proximal phalangeal bone and stable joint in all patients. Range of motion was mean 20 degrees in interphalangeal joint and mean 73 degrees in metacarpophalangeal joint. Tada score showed 'good' in eleven patients (68.8%), 'fair' in three patients (18.7%) and 'poor' in two patients (12.5%). In seven patients those who were able to follow up for a long term showed no significant difference in length of proximal and distal phalangeal bones compared to the opposite thumb. Conclusion: Bilhaut-Cloquet procedure can be applied not only to balanced type of Wassel type III, IV duplicated thumb, but also to unbalanced type or convergent type that focused on functional reconstruction and cosmetic improvement.

Purpose: Dystrophic calcification occurs in damaged or devitalized tissues in the presence of a normal calcium and phosphorus metabolism. There are many reports on dystrophic calcification caused by injections of various types of drugs. The aim of this report is to highlight the fact that dystrophic calcification can be caused by the injection of a foreign body for aesthetic augmentation. Methods: This case report describes a patient presenting with dystrophic calcification caused by an injection of an unknown foreign body approximately 50 years ago. An 80-year-old man had localized cellulitis with swelling and ulceration on the dorsum of the left hand. The radiographs demonstrated a $5{\times}3.5{\times}1.7cm$ lesion between the first and second metacarpal bones and a $5{\times}2.5{\times}1.5cm$ lesion in the hypothenar region. The laboratory data and physical examinations were generally within the normal limits. The microscopic examination revealed dead bone fragments and dense collagenous tissue with dystrophic calcification. Results: After surgically removing the masses, the resulting defects were treated with an abdominal flap. The result was satisfactory in terms of symptoms and appearance. Conclusion: This case suggests that dystrophic calcification can be caused by an injection of a foreign body for aesthetic augmentation.

Purpose: Hexadactyly without thumb is a rare congenital anomaly of the hand where six triphalangeal digits are symmetrically distributed without thumb. Contrary to mirror hands, triphalangeal six digits are symmetrically distributed on each side at the midline with well - differentiated carpal bones, extensor tendons, one ulnar and one radius. The authors developed a new surgical technique based on a three - dimensional concept to correct the hexadactyly and applied to 2 cases of hexadactyly with good functional and aesthetic results. Here we document the surgical technique and its result. Methods: A 16 month old male patient visited our clinic with chief complaints of bilateral hexadactyly deformity. On physical examination most radial first and second digits showed no opposition and adduction motion on both side hands. Radiography showed 6 triphalangeal digits with normal development of carpal, radial and ulnar bone. Right side abnormality was corrected by removal of most radial side extra - digit, rotation and migration of 2nd ray to thumb position and creation of 1st web by transposing a mid - palm based rectangular palmar flap as in Snow & Littler procedure which has been being applied for correction of 1st web syndactyly in cleft hand deformity. Seven months later, left side abnormality was also corrected with the same procedure. Results: Postoperative appearances of the both hands were satisfactory. Flexion, extension, opposition and grasping were possible with the pollicized 2nd ray. Pinching power was 3.0 kg 15 months after surgery and 2.5 kg 22 months after in right hand respectively. Conclusion: In correction of hexadactyly deformity, satisfactory aesthetic and relevant functional results can be expected with authors' newly developed technique: removal of most radial digit, rotation and migration of 2nd digit to thumb position as well as creation of the 1st web space by transposition of mid - palm based rectangular flap.

Background Bioabsorbable plates and screws are commonly used to reduce maxillofacial bones, particularly in pediatric patients because they degrade completely without complications after bone healing. In this study, we encountered eight cases of a delayed foreign body reaction after surgical fixation with bioabsorbable plates and screws. Methods A total of 234 patients with a maxillofacial fracture underwent surgical treatment from March 2006 to October 2013, in which rigid fixation was achieved with the Inion CPS (Inion, Tampere, Finland) plating system in 173 patients and Rapidsorb (Synthes, West Chester, PA, USA) in 61 patients. Their mean age was 35.2 years (range, 15-84 years). Most patients were stabilized with two- or three-point fixation at the frontozygomatic suture, infraorbital rim, and anterior wall of the maxilla. Results Complications occurred in eight (3.4%) of 234 patients, including palpable, fixed masses in six patients and focal swelling in two patients. The period from surgical fixation to the onset of symptoms was 9-23 months. Six patients with a mass underwent secondary surgery for mass removal. The masses contained fibrous tissue with a yellow, grainy, cloudy fluid and remnants of an incompletely degraded bioabsorbable plate and screws. Their histological findings demonstrated a foreign body reaction. Conclusions Inadequate degradation of bioabsorbable plates caused a delayed inflammatory foreign body reaction requiring secondary surgery. Therefore, it is prudent to consider the possibility of delayed complications when using bioabsorbable plates and surgeons must conduct longer and closer follow-up observations.
