Purpose: Nasal bone fracture is the most common facial fracture. Although nasal bone fractures are considered to be minor injuries, the incidence of post-traumatic nasal deformity remains high. This study is designed to support management and patient satisfaction by classifying the simple nasal bone fracture, and survey the care method and result, which is compared with other studies. Methods: From May 2008 to April 2010, 334 patients with simple nasal bone fractures visited our hospital. The incidence, cause, types of nasal bone fracture, treatment, and complications are analyzed according to clinical examination, patient's record and radiographic images. Results: The mean age of patients was 30 years old, with 74% of the patients having been male, and 26% were female. The highest incidence of this fracture was between late teens to late twenties. The causes of nasal bone fracture were the following: having slipped or fallen down (39%), violence (16%), sports accident (14%), traffic accident (11%), industrial accident (6%), and others (16%). Patient's radiographic images were analyzed by Stranc and Robertson classification, frontal impact plane I was 38%, plane II was 16%, plane III was 1%, lateral impact plane I was 21%, plane II was 21%, and plane III was 3%. On average, surgical treatment was performed 7.2 days after trauma under general anesthesia. Closed reduction of nasal bone fracture was performed in 99% of patients. In patients with septal injuries, septal management was performed in 76.7% of cases. Aesthetic surgery was done on same time in 24% of patients. There were some complications, such as residual nasal deformity (7.2%), nasal obstruction (0.9%) and hyposmia (0.3%). Conclusion: According to this study, nasal bone fractures occurred commonly in physically active age groups (age 15~29 years), as a result of having slipped or fallen down, at afternoon and at night time. And it could be treated successfully by closed reduction and septoplasty by 7 days after trauma.

Femur neck fracture is well known as one of the major death cause after trauma in elderly patients, and unsolved fracture due to its frequent association with complications such as avascular necrosis and nonunion. Through meticulous evaluation of the patient, hip and surgeon's experiences, reduction of mortality and morbidity as well as rapid recovery of the patient to the preinjury social and ambulatory status without local complications and revision after treatment is urgently needed. Many factors about this fracture In itself were noted, but we have analyzed 18 femur neck fractures of the patients older than 50 years preliminarily according to age, fracture pattern, osteoporosis, etiology and method of treatment with its delay in association with major complications especially avascular necrosis and nonunion. The results are as follows; 1. Of these 18 fractures, 11 were in females, 8 were caused by minor trauma such as slip-down accident and 4 were associated with definite osteoporosis according to the Sing's classification. 2. Fracture pattern of these 18 are undisplaced in 4, displaced subcapital in 11, displaced transcervical in 3. 11 fractures in the patients older than 60 year are composed of 3 undisplaced or impacted fractures and 8 displaced subcapital fractures. 3. These 18 fractures were treated by closed reduction and Internal fixation with multiple pins in 13, and hemiarthroplasty in 4, but one was not treated to die after discharge from hospital. 4. 4 undisplaced or impacted fractures and 3 displaced transcervical fractures were not associated with any complications such as avascular necrosis or nonunion. But 4 of 6 displaced subcapital fractures were complicated by avascular necrosis, 3 of which were reduced in the varus position within 1 week, and the other was reduced in the good position on 1 week after trauma. There was no complication in 2 displaced subcapital fractures reduced in valgus position within 3 days after trauma. According to the above results, the prognosis of the femur neck fracture is dependent upon the fracture pattern and delay in its treatment. So it is inevitable to reduce the fracture in anatomical or valgus position as early as possible. But the arthroplasty may be needed in displaced subcapital fractures delayed for several days, with its reluction in extreme varus position or impossible and with pre-existing disease in the same hip Joint (total hip replacement).

Pyogenic granuloma is a overzealous proliferation of a vascular type connective tissue as a result of some minor trauma and is a well circumscribed elevated, pedunculated or sessile benign inflammatory lesion of skin and mucous membrane. The clinical features of pyogenic granuloma are indicative but not specific and nearly all cases of pyogenic granulomas are superficial in nature, and there is little if any mention in the literature of these lesions producing alveolar bone even jaw bone loss. This case is somewhat unique in that the lesion was an obvious histologic pyogenic granuloma; however, it appeared to invade the mandibular bone which resulted in the loss of the adjacent teeth. A 12-year-old boy came to Seoul National University Dental Hospital with chief complaints of left facial swelling. The features obtained were as follows; Plain radiograms showed a large well-circumscribed radiolucent lesion on left mandibular ramus area, which made severe expansion of lingual cortex and displacement of lower left 3rd molar tooth germ. Computed tomograms showed large soft tissue mass involving left masticator space with destruction of left mandibular ramus. Histologically, sections revealed loose edematous stroma with intense infiltration of inflammatory cells and proliferation of vascular channels. Also, there were focal areas of extensive capillary proliferation, bone destruction and peripheral new bone formation.

Purpose: Frostbite can affect still soldiers. Initial clinical manifestations are similar for superficial and deep frostbite, so early treatment is identical. It is under-estimated by physicians. We try to identify the challenges of managing these complex tissue injuries. Methods: A retrospective analysis of 84 patients hospitalized at AFCH from 2009 to 2015 was conducted. We investigated differences of epidemiological characteristics, identification of soft tissue injury, treatment and complications between superficial (SF: 43; 51.2%) and deep (DF: 41; 48.8%) frostbite. Results: The major (94.0%) developed frostbite in dry circumstances (89.3%). Wet circumstances (66.7%) were more susceptible to DF rather than dry (46.7%). The 38 (45.2%) arrived to specialist within 7days. Most prone sites were feet, followed by hands. Toes had more deep injuries. DF presented more increased levels of ALT, CPK, CKMB, CRP. The bone scan of W+S+ was 48.3%, 87.1% and W+S- was 20.7%, 12.9%, respectively. The treatment resulted in improved or normalized perfusion scan with matching clinical improvement. It was a good tool to assess treatment response. Eighteen normal and 8 stenotic type of PCR resulted in normal with matching clinical improvement. One continuous obstructive waveform led to minor amputation. Twelve underwent both PCR and MRA. Among 6 normal PCR, 5 showed normal and one stenosis in MRA. All 5 stenosis and one obstruction showed the same findings in MRA. It was a good tool to evaluate vascular compromise. They were treated with rapid rewarming (11.6%, 22.0%), hydrotherapy (16.3%, 29.3%), respectively. Six (14.6%) underwent STSG, 2 (4.9%) had digital amputation in DF. Berasil, Ibuprofen, Trental were commonly administered. PGE1 was administered selectively for 6.8, 10.8 days, respectively. Raynaud's syndrome (16.3%), CRPS (4.7%), LOM (14.6%) and toe deformity (4.9%) were specific sequelae. Conclusion: We should recommend intensive foot care education, early rewarming and evacuation to specialized units. The bone scanning and PCR should allow for a more aggressive and active approach to the management of tissue viability.

The mucocele is a mucus extravasation cyst arising from the salivary gland. Although it is a common?lesion of the minor salivary gland, it is uncommon when it originated from the submandibular gland. The ranula is a form of mucocele which specifically occurs in the floor of the mouth and the sublingual gland is generally accepted as the origin of ranula. They can be classified into two types based on extent: simple ranula are confined to the sublingual space and plunging ranula extend into the adjacent space. It is difficult to differentiate the submandibular gland mucocele from the plunging ranula because both of them can occupy the submandibular space. A 37-year old male visited our clinic with the chief complaint of left facial swelling. The patient's history revealed that he had suffered from a cystic lesion on the left side of the floor of the mouth 10 months previously. He supposed the cystic lesion had come from trauma at other dental clinics. Using CT and MRI, we diagnosed a simple ranula on the sublingual space and a submandibular gland mucocele. We then excised the mucocele with the submandibular gland by an extraoral approach and the sublingual gland by an intraoral approach under general anesthesia. We report a rare case of an enormous submandibular gland mucocele which extended into the pterygoid plate and parapharyngeal space with good surgical results.

Lumbar disc herniation in the adolescent is rare. The clinical features of adolescent lumbar disc herniation are typically different from those of adults. Many adolescent with that disease may be misdiagnosed as minor trauma, muscle sprain, tight hamstrings or scoliosis. Published series reiterate that adolescents, as opposed to adults, do not respond well to conservative treatment. In adolescent lumbar disc herniation with hamstring tightness, the neurologic defects are improved shortly after, discectomy, but the hamstring tightness continue and remain even after 1 year. Earlier discectomy and adjunct postsurgical conservative measures can provide a greater opportunity for correction and stabilization of scoliotic posture. We here report on a case of adolescent lumbar disc herniation that was misdiagnosed by knee injury during 2 years. After posterior partial discectomy, the hamstring tightness and scoliosis was disappeared without complication.

Volkmann's ischemic contracture is the end result of an untreated, delayed or Inadequately decompressed compartment syndrome in which muscle ischemia and necrosis have occurred. Once the muscle necrosis have happened, the involved muscle undergo permanent change into fibrous tissue. So secondary shortening and distal joint contracture will be a final outcome, which results in marked functional impairment of hand and forearm. Even though several procedures, such as muscle sliding operation has been attempted, overall results were far from satisfaction, compare to healthy opposite hand. The management of these unfavorable condition of the forearm and hand was regarded as one of challenging area in orthopedics. Recently new approach, using microsurgical technique which transfers functioning muscle unit, has been developed and its result was much better than any other methods in the aspect of an active motion. Among these musculocutaneous free flaps, gracilis has obtained special reputation due to its easiness to handle such as elevation of flap and reliable neurovascular pedicle. Other advantages are flexibility of flap size to adjust variable size of the defect in the forearm and minor morbidity of the donor site. Authors have performed 7 cases of functioning gracilis musulocutaneous free flap transplantation for the functional loss of forearm and hand due to Volkmann's ischemic contracture or muscle and skin defect due to severe trauma since November, 1981 till May, 1991. The results in most cases were satisfactory and acceptable.

Epidermolysis bullosa (EB) is an inherited skin disease characterized by blister formation of the skin following just minor trauma or spontaneously. The main classification of EB is based on the localization of the blistering. In epidermolysis bullosa simplex, the blister formation is intraepidermal; in epidermolysis bullosa junctionalis the blister formation in the epidermal-dermal junction; in the dystrophic forms of EB blister formation is intradermal. Oral manifestations of recessive dystrophic EB are characterized by rampant caries, crowding, microstomia, ankyloglossia, vestibular obliteration. Dental therapy may be well provided to patient with recessive dystrophic EB by using general anesthesia especially in case of poor cooperation. A two years old girl with recessive dystrophic EB visited our clinic for rampant caries. She was hospitalized for severe anemia and fever, and we provided dental therapy under general anesthesia. Extraction of incisors and stainless steel crown restoration of primary molars were performed.

Background: Millard's rotation-advancement repair, which is used by many surgeons, can make a natural philtral column, but most surgeons use a modification of the rotation-advancement flap. The purpose of this article is to introduce a modification utilized by the authors and to provide detailed surgical procedure. Methods: We retrospectively reviewed 82 patients' medical records and presented surgical technique and outcomes. The main features of the authors' strategy are emphasizing horizontal length of the lip, orbicularis oris muscle duplication for improving the definition of the philtral column, overcorrection of domal portion than the non-cleft side in order to compensate for the recurrence during growth. Two judges rated two times the appearance of the patients' nose and lip using Asher-McDade aesthetic index. Intra- and interobserver reliabilities were determined using Cohen's kappa statistics. Results: All patients recovered eventually after surgery; however, two patients have a minor complications (wound infection in one patient, wound disruption due to trauma in the other patient). The improvement of the aesthetic results can be achieved with this modified Millard technique. Total mean scores of the Asher-McDade index was 2.08, fair to good appearance. The intraobserver reliabilities were substantial to almost perfect agreement and the interobserver reliabilities were moderate to almost perfect agreement. Conclusion: We modified Millard method for repair of complete unilateral cleft lip. The surgical outcomes were favorable in long-term follow-up. We hope our technique will serve as a guide for those new to the procedure.

Objective : It is rare that the medial loop in the V2 segment of the vertebral artery (VA) causes compression of the proximal cervical root of the spinal cord without leading to bony erosion and an enlarged foramen. We evaluated the clinical significance and incidence of the medial loop in the V2 segment of the VA. Methods : We reviewed the records from 1000 consecutive patients who had undergone magnetic resonance imaging evaluation of the cervical spine between January 2005 and January 2008. The inclusion criteria were that over a third of the axial aspect of the VA located in the intervertebral foramen was inside the line between the most ventral points of the bilateral lateral mass, and that the ipsilateral proximal root deviated dorsally because of the medial loop of the VA. We excluded cases of bone erosion, a widened foramen at the medial loop of the VA, any bony abnormalities, tumors displacing VA, or vertebral fractures. The medical records were reviewed retrospectively to search for factors of clinical significance. Results : In six patients (0.6%), the VA formed a medial loop that caused compression of the proximal cervical root. One of these patients had the cervical radiculopathy that developed after minor trauma but the others did not present with cervical radiculopathy related to the medial loop of the VA. Conclusion : The medial loop of the VA might have a direct effect on cervical radiculopathy. Therefore, this feature should be of critical consideration in preoperative planning and during surgery.
