The aim of this study was to achieve the healing of peri-implantitis defects and the hard tissue regeneration using the augmentation of a xenograft on defect site. Two patients were treated with the surgical approach. With a full muco-periosteal flap elevation, the implant surfaces were exposed and taken the debridement of granulation tissue around the abutment. Each surface of the abutments was prepared with the air-abrasive device (PerioFlow$^{(R)}$) for decontamination. Bovine-derived bone mineral (Bio-Oss collagen$^{(R)}$) was then used to fill the defects, and no membrane was placed on the grafting site. Radiographs and clinical photo was taken to compare from baseline status. Within the limits of the present case, this case shows the significance of the surgical treatment of peri-implantitis. And this also verifies the stability of bovine-derived bone mineral and effectiveness of Air-abrasive device (PerioFlow$^{(R)}$).

A 3rd degree burn on the heel including the Achilles tendon is vulnerable and requires active treatment to improve the functional outcomes. Previously, there have been a few treatments on severe burns, such as amputation, debridement or simple skin graft. The cooperative technique of an anterior lateral thigh flap with Achilles tendon reconstruction can be an innovative procedure that preserves the major arteries. The authors review a case and report the clinical outcome.

Tracheo-innominate artery fistula (TIF) is a rare, life-threatening complication of tracheostomy that makes it difficult to secure the airway due to massive bleeding, constituting a medical emergency. Therefore, most successful surgical treatments include innominate artery debridement and tracheal fistula repair. Herein, we report a case of successful surgical treatment of a TIF while maintaining cerebral blood flow through an artificial vascular graft.

Objects : Because of the nonspecific nature of symptoms in tuberculous spondylitis, a delay in the diagnosis can result in progressive neurologic deficits. The authors evaluate the clinical and the radiological results of the 10 cases of surgically treated tuberculous spondylitis. Clinical materials & Methods : We retrospectively analyzed the medical records of 10 patients with tuberculous spondylitis who were treated between February 1996 and March 2000. Six patients were female, and four were male. Mean age was 43 years old, and mean follow-up period was 20.5 months. All patients were treated with 12 months of antituberculous medication postoperatively, and were followed by complete blood count, ESR, spine X-ray and MRI. Results : The lumbar spine was involved in 5 patients, the thoracic in 4, and the thoracolumbar in one. The infected vertebral bodies were 2.8 in average. The associated lesions were pulmonary tuberculosis in 3 cases, and renal tuberculosis in one. Five patients were treated by anterior debridement and fusion with bone graft using anterior instrumentation, 2 with anterior debridement and fusion with bone graft(Hong Kong procedure only), 1 with Hong Kong procedure with posterior spinal instrumentation, and 2 were managed with posterior debridement and posterior spinal instrumentation. All patients improved after operation, and the average kyphotic angle decreased postoperatively. Postoperatively, one patient had a fistula at the operative site. Conclusion : The debridement and minimal level fusion of motion segment with instrument fixation is one of surgical option for tuberculous spondyltis to preserve the spine motion segment as much as possible. Spine instability and kyphosis were prevented by anterior and posterior spinal instrumentation. But, large number of cases and longer period follow-up study in future will be needed to confirm the long term results.

Purpose: Purpura fulminans is a rare but rapidly progressive, serious, often life-threatening disorder in childhood, which is complicated with septic shock or disseminated intravascular coagulopathy during acute infection. It occurs first as acute-onset petechial rash, and spreads rapidly into full thickness skin and soft tissue necrosis. In the past, it had high mortality rate, up to 80%, but recently, survival rate has increased due to early diagnosis, and rapid advancement of critical care and antibiotics. From our experiences of PF management, we would like to review the pathophysiology and suggest the surgical treatment guideline about meningococcal induced purpura fulminans. Methods: Two cases of purpura fulminans over the last 3 years were reviewed retrospectively about reconstructive management. After they were treated resuscitative management initially by the critical intensive care, reconstructive surgery was performed by plastic surgeon as soon as the patients were vitally and mentally stable. Results: There were 6 procedures in case 1, and 3 procedures in case 2. The mean delayed period from admission with sepsis to the first surgical debridement was 24 days and 42 days, respectively. Total hospitalization period was 103 days and 69 days, respectively. All of them were treated with debridement and split thickness skin graft, but delayed debridement was superior to early one in the point of preserving much more tissues. Conclusion: From our experience, we suggest that conservative therapy to the wounds appears to be the best tool in the initial vitally unstable period in order to preserve as much tissues and functions as possible if no active inflammation and compartment syndrome are detective.

배경: 조기진단과 적극적인 수술치료에도 불구하고 감염성 심내막염의 수술은 여전히 높은 사망률과 합병증을 보이고 있다 저자들은 감염성 심내막염으로 수술을 받은 환자들의 중단기 성적과 함께 원인균주에 따른 임상양상, 합병증과 수술사망의 위험인자, 특히 광범위 절제 및 심기 저부 재건술과 같은 보다 적극적인 수술법이 사망률과 이환율에 어떠한 영향을 미치는지 알아보기 위해 된 연구를 시행하였다. 대상 및 방법: 1995년 1월부터 2006년 6월까지 감염성 심내막염으로 진단되어 수술을 받은 79명의 성인 환자를 대상으로 시행하였다. 자가판막 심내막염이 63명이었고 인공판막 :감염은 16명이었다. 침범된 판막으로는 승모판 29예(36%), 대동맥판막 27예(34%), 승모판-대동맥판막 동시 침범 17예(21.5%) 삼첨판 3예, 폐동맥판막 3예였다. 균 동정이 안 되었던 경우가 27예(34.17%)였고 연쇄상 구균이 26예, 포도상 구균이 15예 기타 11예였다. 13예(16.5%)에서 판막 성형술을, 66예(82.9%) 에서 판막치환술을 시행하였는데 10예의 동종이식을 포함한 26예에서 조직판막이 사용되었고 40예에서는 금속판막이 사용되었다. 판막 성형 혹은 치환과 더불어 총 28예(35.4%)에서 대동맥 근부 치환 혹은 재건, 심기저부 재건, 농양배제술(abscess exclusion)과 같은 보다 더 침습적인 수술이 병행되었다. 결과: 조기사망은 4명(5.1%)이 심부전, 폐렴, 급성호흡부전 증후군, 범발성 혈관 내 응고장애로 사망하였으며, 2명이 외래관찰기간 중 만기 사망하였다. 2명에서 심내막염이 재발하여 2.6%의 재발률을 보였다. 포도상 구균에 의한 감염, 응급에 준하는 수술, 활동성 심내막염 상태에서 수술한 경우가 단일변량 분석에서 술 후 사망 및 주요 합병증 발생에 영향을 미치는 것으로 나타났다. 감염조직의 광범위 절제 후 필수 불가결한 보다 더 침습적인 재건술 및 근부치환의 시행 여부는 술 후 사망률에 영향을 미치지 않았고 주요 조기 합병증의 발생과도 무관하였다(p=0.51). 배양 음성인 경우 사망 및 주요 합병증 발생에 영향을 미치지 않았고 침범하는 판막의 종류(인공판막 대 자기판막)도 통계적으로 유의성이 없었다. 걸론: 감염성 심내막염에 있어 수술 전 진단 및 내과적 치료 과정에 많은 주의를 기울여야 하며 수술의 적응증이 된다면 환자의 임상적 상태가 악화되기 전 시점에 외과적 치료가 이루어져야 술 후 결과가 향상될 수 있을 것으로 판단된다. 침습적인 재건술이나 근부치환을 적용하더라도 술 후 사망률 및 주요 합병증 발생에 통계적 유의성을 보이지 않으므로 보다 적극적인 감염원의 제거와 해부학적 재건이 요구된다.

A review of the literature was presented, illustrating the effect that gingivally retained orthodontic elastic bands have on the periodontal tissues. A case report was presented for treatment of mobile maxillary central incisors secondary to a subgingival elastic band. Following surgical removal of elastic band and periodontal debridement, the teeth were successfully retained with active orthodontic appliances. Until a harmless radiopaque medium can be safely incorporated into elastic bands, extreme caution in their use should be observed. Not only should all attempts be made to anchor the elastic bands to the clinical crown, but the patient should receive through instructions in their placement and removal.

The incidence of arthritis in the ankle is relatively low compared to other joints. On the other hand, it receives a lot of pressure per unit area, is vulnerable to damage, and arthritis can arise after trauma. Early ankle arthritis can be considered a case of osteophyte subchondral sclerosis without narrowing of the joint space. Conservative treatment, such as weight control, insole use, drug use, and injection therapy for early ankle arthritis, is effective and can be considered before surgical treatment. Nevertheless, if pain is persistent, surgical treatment to remove bony spurs is effective. Ensuring that there is no other cause of pain when deciding whether to perform an operation is very important.

Necrotizing fasciitis (NF) is an infection that spreads along the fascial planes, causing subcutaneous tissue death characterized by rapid progression, systemic toxicity, and even death. NF often appears as a red, hot, painful, and swollen wound with an ill-defined border. As the infective process continues, local pain is replaced by numbness or analgesia. As the disease process continues, the skin initially becomes pale, then mottled and purple, and finally, gangrenous. The ability of NF to move rapidly along fascial planes and cause tissue necrosis is secondary to its polymicrobial composition and the synergistic effect of the enzymes produced by the bacteria. Treatment involves securing the airway, broad-spectrum antimicrobial therapy, intensive care support, and prompt surgical debridement, repeated as needed. Reducing mortality rests on early diagnosis and prompt aggressive treatment.
