OBJECTIVE: The purpose of this study is to report the technical feasibility and the result of one stage operation for the bursting fracture of the thoracolumbar spine by posterior approach. METHODS: Seven patients underwent corpectomy and replaced the space with titanium mesh cage filled up with autologous bone pieces through unilateral posterior route after removal of the facet joint and the pedicle followed by pedicle screw fixation at the same surgical field. RESULTS: All patients tolerated the procedures well except one patient complicated with air embolism. Postoperative radiographs showed effective decompression and well placed instruments. Preoperative neurological deficits disappeared completely in two patients but some deficits persisted in the remainders. In two patients, epidural venous bleeding was troublesome and he needed transfusion of 5 pints of packed red blood cell. And another patient complicated with air embolism during operation was recovered with impunity after operation. To insert the mesh cage through the narrow corridor posterolaterally, it was unavoidable to sacrifice one spinal root. CONCLUSION: In spite of technical difficulty, one stage spondylodesis for the bursting thoracolumbar spine though unilateral posterior approach seem to be an effective operative procedure.

According to the increase in use of implants in clinical dentistry, new kinds of complications happen. Complications that can happen during implant placement are bleeding, nerve injury, jaw fracture, fenestration of maxillary sinus or nasal cavity, dehiscence, fenestration, injury of adjacent tooth. And complications that can happen after implant operation are infection, bleeding, hematoma, chronic sinusitis, peri-implantitis. Problems that are confronted during implant placement happen by inadequate preoperative treatment plan, inadequate consideration about individual anatomic difference, inadequate operation process and lack of experience of clinician. It is important that clinicians consider possible complications in advance and make a comprehensive treatment plan. We report the patient who was happened ramus fracture during block bone harvesting from ramus of severely atrophic mandible, the patient who came to emergency ward due to postoperative swelling and bleeding and the patient whose implant was migrated to maxillary sinus with a review of literature.

Cyst is pathologic disease develops in hard tissue as well as soft tissue, which is lined by epithelium filled with liquid, semi-liquid, or air. Origins and symptoms of the cyst are various according to region, and symptoms are malocclusion, diversion of root, tooth mobility, periapical swelling, discoloration and lesion expansion, because the odontogenic cysts begin in the numerous rests of odontogenic epithelium. But almost cysts produce no symptoms unless secondary infection occurs. Treatment of small cysts may include extraction, endodontic therapy, and apical surgery. Treatment of a large cysts usually involves surgical removal (enucleation), Marsupialization(a method of decompression) or combination of two before mentioned. Bone graft is done for helping of bone defect healing at the same time of enucleation This clinical research from January 2000 to December 2005, analyzed by the age, sex, classification, size, region, treatment method, whether or not of bone graft of cyst in the jaw in Daegu Catholic University Hospital.
