  • The goal of surgery of chronic osteomyelitis is removal of dead bone and achieving a viable and vascular environment. During saucerization, the sequestrum could be checked and resected completely. But it can causes vascular injury by massive soft tissue dissection in saucerization of chronic osteomyelitis. Recently, we experienced medulloscopy in the treatment of chronic osteomyelitis and it is possible for us to visualize the sequestrum, to do complete resection of dead bone and to reduce vascular injury during operation.

  • Eighty-nine patients with mandibular fracture were treated by open reduction and internal fixation using the monocortical titanium miniplate(Leibinger Co.). Postsurgical intermaxillary fixation was carried out for 2 to 18 days according to the patient's status. Seven patients developed infections postoperatively(7.9%). Five patients were favorably treated by incision and drainage and/or saucerization. But two patients were not controlled by early surgical intervention and should have been followed by plate removal, saucerization and secondary reconstruction including the bone graft. This article reports the postoperative infection associated with miniplate fixation of mandibular fractures and discuss the incidence, cause, treatment and prognosis with careful case analyses.

  • Purpose : This study sought to examine the aspects of crestal bone resorption and to evaluate the clinical outcomes of the TiUnite$^{(R)}$ (Nobel Biocare, Sweden) anodized implant system. Materials and Methods : Among the 67 patients (211 fixtures) who were treated using TiUnite(r) implants at Seoul National University Bundang Hospital between March 2004 and January 2007, 26 (91 fixtures) were considered in this study. Initial and secondary stabilities were measured using Periotest$^{(R)}$ and Ostell(tm) Mentor. The radiographic evaluation of crestal bone resorption was carried out by measuring the change in crestal bone level at the time of surgery compared to that 1 year after loading. Panoramic radiograph and periapical radiograph were used. Based on the radiographic findings, the shapes of crestal bone resorption were classified. Results : The average amount of crestal bone resorption after 1 year of functional implant loading was 0.30 mm. There was no saucerization in 40 implant fixtures (43.9%), although more than 1 thread were exposed in 51 implant fixtures (56.6%). The success rate of the implants was 94.5%, and the survival rate was 100%. Conclusions : Good clinical outcomes and minor crestal bone resorption were noted in this study. Saucerization for the establishment of biological width was not a general finding in the TiUnite$^{(R)}$ anodized implant system.

  • Statement of problem: $Periotest^(R)\;and\;Osstell^{TM}$ were known as the most objective and quantitative mobility tests available for evaluating stability of implant in vivo. Although a correlation between PTV widely used and ISQ recently introduced exist, a PTV was corresponded to various ISQ. A correct evaluation of implant stability could be obtained only after one has a thorough understanding of the limitations of devices and factors that affect measurements. Purpose: The purpose of this study was to investigate the causes of variables in the values obtained with these two tests. Material and method: A total of 333 implants 134 $Br{\aa}nemark$, 5 Silhouette and 194 ITI implants were investigated. Result: 1. There was a correlation between PTV and ISQ (Spearman correlation =0.39, p<0.0001) 2. The factors that affected ISQ were diameter of implant future, location of implant and implant system (submerged type vs non-submerged type). 3. The factors that affected W were dimeter of implant future, location of implant, and elapsed time after implant placement. 4. There was no significant difference between different surface treatments of RBM, smooth surface and ti-unite on PTY and ISQ. 5. In radiographic finding, no saucerization or bone resorption has been detected in implants with ISQ values that were above the average level of each PTV. These higher values had higher bone densities around the implant fixture. Saucerization was observed in the most impants with ISQ values that were below the average level of each PTV. Conclusion: There was a correlation between ISQ and PTV. However, each measuring methods had factors influencing the measured values. PTV were less sensitive to marginal bone resorption and influenced with the striking point on an implant to the level of bone. With ISQ, the height of implant from bone level to transducer should be considered.

  • The proper management of mandibular fractures involves reduction, rigid fixation, and immobilization to allow bone healing. Nonunion or malunion at the fractured sites is a well-known complication of fracture when the treatments are inappropriate. We present a case of left mandibular fracture due to shrapnel during the Korean War. The patients did not receive appropriate treatment at that time, so nonunion and malunion developed. Sixty years after the accident, mandibular osteomyelitis on the fracture site developed due to dental-origin inflammation. The treatment was based on relatively conservative care, such as saucerization and administration of antibiotics. There was no complication during the short-term follow-up. We present the case with literature review.

  • This is an extermely rare disease and a case of tuberculous osteomyelitis of mandible in a 45-year-old woman was reported. The patient was visited for complaining slight facial swelling on left side and purulent discharge from extracted socket. Roentgenograhic examination of the mandible revealed bone destruction on left side of mandibular body. Destructive lesion was removed with saucerization and specimen from the involved soft tissue and bone were sent for microscopic examination. This case proved to be primary tuberculous osteomyelitis caused by the absence of primary focus. After 3 months follow-up check, we noticed good prognosis of bone and soft tissue healing.

  • This study evaluated the short-term outcome of treating fractures of the mandible with bioabsorbable plates. Thirty-four fractures of the mandible in 27 patients were treated by open reduction and internal fixation using bioabsorbable plates and 2.4-mm, 2.0-mm, and 1.5-mm pre-tapped screws. The duration of intermaxillary fixation ranged from 0 to 23 days, with a mean of 5.3 days. Patients were evaluated for complications during the follow-up period, which ranged from 2 to 18 months. Five patients(18.5%) experienced complications. These included infection (four patients), and premature occlusal contact(one patient). Except for one case, all complications were minor and adequately managed with incision and drainage, elastic traction, and medication. Delayed infection (osteomyelitis) developed in a symphysis fracture and was treated by saucerization and antibiotics. The fracture line subsequently showed complete consolidation. Bioabsorbable plates can be selectively used for internal fixation in mandibular fractures with the advantage that they do not need to be removed.

  • The objective of this case report was to evaluate meniscal suturing for a young patient with a chronic radial tear of the incomplete discoid lateral meniscus. The patient underwent saucerization in conjunction with repair of the displaced radial tear of the discoid meniscus. Six-months after surgery, arthroscopic examination showed the repaired meniscus to be healed well with good continuity. Repair of radial tears, even chronic tears, should be considered for young patients with torn discoid lateral menisci.

  • With the use of antibiotics and improved dental care, osteomyelitis of the jaw is less common these days, But sometimes the management of osteomyelitis is more difficult because of appearance of resistant organisms to antibiotics. Treatment of the steomyelitis are incision and drainage, closed catheter irrigations, sequestrectomy, saucerization, hyperbaric ocygen therapy, and resection with or without bone graft. We experienced advanced osteomyelitis due to delayed treatment of left mandibular angle fracture. He have medical history of pschysoprenia. We decided to treat the patient with open reduction and closed cather irrigation. We achived reconsolidation of mandibular fracture accompanied by osteomyelitis by complete removal of inflammatory tissues, rigid fixation with miniplate and closed catheter irrigation.

  • Wegener's granulomatosis (WG) is an autoimmune disease of unknown etiology characterized by the triad of necrotizing granulomatous lesion in the upper and lower respiratory tracts or both, disseminated vasculitis involving both small arteries and veins, and necrotizing glomerulonephritis. The most common oral lesions associated with WG are ulceration and strawberry gingivitis. A 47-years old man in medical care associated WG was consulted our Division of Oral and Maxillofacial Surgery for the chief complaint of toothaches. Pre-operative panorama showed the alveolar radiolucency and the loss of lamina dura regarding the left upper teeth. An oropharyngeal magnetic resonance imaging also revealed the increased bone marrow signal intensity on the left maxilla. Under the impression of maxillary osteonecrosis due to WG, maxillary saucerization with removal of involved teeth was performed. We obtained good results and report the first case of WG in Korea, with the review of literatures regarding oral and general systemic features.
