활막 육종은 수부에서는 드물게 발생하며 광범위 절제술을 요한다. 수부의 광범위 절제술을 시행할 때는 충분한 절제연을 얻어야 하지만 기능적인 면을 고려한 재건술이 요구된다. 저자들은 타병원에서 불완전 병소내 절제술후 전원된, 46세 남자의 우측 수지 무지구근 부위 활막육종에 대해 대능형골 및 제1 중수지골을 포함한 광범위 절제술 후, 비골 이식술과 전외측 대퇴 피판 이식술을 시행하여 재건술을 시행하여 우수한 결과를 얻은 증례를 보고하고자 한다.

Chondroblastomas are rare entities accounting for approximately 1% of all primary bone tumors. We describe a case of a 7-year-old girl with a giant chondroblastoma of the maxilla, treated with bilateral class III maxillectomy and reconstruction with a double-barreled and double skin paddle fibular free flap. We show evidence of an excellent aesthetic outcome at 6 months' follow up with no evidence of tumor recurrence.

We present a case of a 57-year-old male patient who presented with squamous cell carcinoma on his mouth floor with cervical and mandibular metastases. Wide glossectomy with intergonial mandibular ostectomy, and sequential reconstruction using fibular osteomyocutaneous free flap were planned. When the anastomosis between the peroneal artery of the fibular free flap and the right lingual artery was performed, no venous flow was observed at the vena comitans. Then re-anastomosis followed by topical application of papaverine and lidocaine was attempted. However, the blood supply was not recovered. Warm saline irrigation over 30 minutes was also useless. Microvascular thromboses of donor vessels were clinically suspected, so a solution of 100,000 units of urokinase was infused once through a 26-gauge angiocatheter inserted into the recipient artery just at the arterial anastomotic site, until the solution gushed out through the flap vena comitans. Immediately after the application of urokinase, arterial flow and venous return were restored. There were no complications during the follow-up period of 11 months. We believe that vibrating injuries from the reciprocating saw during osteotomies and flap insetting might be the cause of microvascular thromboses. The use of urokinase may provide a viable option for the treatment of suspicious intraoperative arterial thrombosis.

Segmental defects of the tibia after open fractures, sepsis and a tumor surgery are among the most difficult and challenging clinical problems. Tibia defects in these situations are complicated with infection and are resistant to conventional bone grafting techniques. The aim of this study is to report the results and discuss the role of free flap followed by ipsilateral vascularized fibular transposition (IVFT) for reconstruction of tibia defects. Ten patients had free flap followed by IVFT in the period 1989~2007. Mean age was 25.3 years. The patients were followed for an average of 3.4 years. All flaps were survived including 1 case with venous thrombosis requiring additional surgery. The average time to union of proximal and distal end was 5.2 months, 8.2 months, each other. All transposed fibula were viable at last follow-up. IVFT offers the advantages of a vascularized graft. In patients with large bone and soft tissue defects combined with infection, free flap followed by IVFT is an useful and reliable method without microvascular anastomosis.

Primary intraosseous squamous cell carcinoma (PIOSCC) is very rare type of squamous cell carcinoma (SCC) that occurs within the jaw and arises from remnants of odontogenic epithelium with no connection to the oral mucosa. This study reports two cases of PIOSCC of the mandible. Reported in this article are two cases of PIOSCC of the mandible that were treated with resection and reconstruction using a fibular free flap. The first case was a 36-year-old male patient who complained of right mandibular pain. Computed tomography (CT) and panoramic radiograph revealed a large radiolucency in the mandibular ramus area. At first, an odontogenic keratocyst was tentatively diagnosed, and an excision procedure was carried out at another clinic. A final biopsy after cyst enucleation revealed well-differentiated SCC, so we proceeded with segmental mandibulectomy and reconstruction using a fibular free flap. The second case was a 48-year-old male patient with left mandibular pain. CT and panoramic radiograph revealed irregular radiolucency in the mandibular angle area near tooth #38. At first, osteomyelitis was tentatively diagnosed, and a curettage was carried out. A later biopsy revealed well-differentiated SCC, so segmental mandibulectomy and reconstruction with a fibular free flap were secondarily performed. Our two cases have had no recurrence. The facial appearance of both patients is satisfactory, and the neo-mandibular body created using a fibular bone transfer displays adequate bony volume.

구강암 등의 병소로 인해 하악골의 절제를 시행한 환자는 구강악안면계의 재건을 통한 기능적, 심미적 회복이 중요하다. 하악골의 재건에 많이 사용되는 비골유리피판은 임플란트 식립을 동반한 보철적 수복에 있어 용이하다. 그러나 성장기 환자는 비골의 크기가 작고 잔여 성장이 남아있을 수 있어 임플란트를 이용한 치료 시 어려움이 존재한다. 본 증례는 골육종으로 하악골 절제술 및 비골유리피판을 이용해 하악골의 재건을 시행한 11세 여성 환자로, 임플란트 지지 고정성 보철물을 이용한 보철적 수복을 통해 기능적, 심미적 회복을 도모하였다. 임플란트의 식립 부위 및 개수, 보철물의 형태적 고려를 하였으며, 성장기인 13세에 임플란트 지지 고정성 보철 수복을 완료하였고, 추가로 1년간의 경과 관찰을 시행한 바 안정적인 결과를 얻었기에 보고하고자 한다. 그러나, 이후의 추가적인 검진을 통해 악안면계의 변화를 관찰하는 것이 필요하겠다.

In the present study, a fibular osteotomy guide based on a computer simulation was applied to a patient who had undergone mandibular segmental ostectomy due to oncological complications. This patient was a 68-year-old woman who presented to our department with a biopsy-proven squamous cell carcinoma on her left gingival area. This lesion had destroyed the cortical bony structure, and the patient showed attenuation of her soft tissue along the inferior alveolar nerve, indicating perineural spread of the tumor. Prior to surgery, a three-dimensional computed tomography scan of the facial and fibular bones was performed. We then created a virtual computer simulation of the mandibular segmental defect through which we segmented the fibular to reconstruct the proper angulation in the original mandible. Approximately 2-cm segments were created on the basis of this simulation and applied to the virtually simulated mandibular segmental defect. Thus, we obtained a virtual model of the ideal mandibular reconstruction for this patient with a fibular free flap. We could then use this computer simulation for the subsequent surgery and minimize the bony gaps between the multiple fibular bony segments.

Extensive bone loss associated with severe vascular injury remains a challenge for lower extremity reconstruction. The fibular free flap has been utilized for many decades to reconstruct long-segment tibial defects. We present an unusual scenario of unilateral weight-bearing, wherein we salvaged the sole lower extremity by transfer of the fractured ipsilateral fibula and a bipedicled skin flap. A 38-year-old man sustained a severe crush injury in the right leg with loss of circulation. His left lower leg had a soft tissue defect measuring 20×15 cm with an exposed comminuted fracture and a 17-cm tibial defect, along with a segmental fracture of the fibula. Subsequently, we reconstructed the tibial defect by transferring a 17-cm-long section of the ipsilateral fibula. We covered the soft tissue defect with a bipedicled skin flap. The patient eventually began to ambulate independently after surgery.

고려대학교 의과대학 정형외과학 교실에서 광범위한 연부조직결손을 동반한 감염된 경골결손 34례에 대하여 생비골 및 생피부편이식을 시행하고 얻은 결과는 다음과 같다. 1. 국소염증이 완전히 조절되지 않은 상태에서도 생비골 및 생피부편 이식이 가능하였다. 2. 생비골 및 생피부편 이식술을 동시에 시행함으로써, 생피부편의 임상상태로 생비골 이식의 성공여부를 간접적으로 알 수 있었다. 3. 추시기간동안 이식된 비골은 비후되었으며, 이식골의 흡수는 없었다. 4. 경골을 부분절제한 경우에는 이식비골의 골절은 발생되지 않았다. 5. 이식된 비골의 비후는 수술부위의 국소염증 상태에 영향을 받는 것으로 사료되었다.

편평세포암으로 하악골 절제술과 비골 피판 이식을 받은 경우 하악의 기능적 움직임이 저해될 수 있다. 하악골이 절제된 측은 근육부착의 소실로 인해 근기능이 약화되어 중심교합 및 편심교합에서 불안정한 교합접촉을 초래한다. 본 증례는 하악골절제술과 비골이식 재건술을 받은 63세 남성에서 전치부의 상실된 치아를 수복하기 위해 고정성 보철물이 필요했던 경우이다. 중심 및 편심교합에서 교합력의 크기에 따라 교합접촉 양상의 변화가 관찰되었다. Functionally generated path 기법과 디지털 영상기술을 적용하여 환자의 하악운동과 조화되고 적절한 수직고경이 있는 기능적으로 최적화된 고정성 보철물을 제작할 수 있었기에 보고하고자 한다.
