Cysts of the mandibular condyle are rare and can be difficult to diagnose and treat. Clinically, a simple bone cyst is asymptomatic and often discovered incidentally on routine radiographic examination. This report shows an atypical simple bone cyst occurring in the mandibular condyle showing recurrence after surgical curettage. Radiologically, this lesion involving the mandibular condyle should be distinguished from other similar lesions such as a chondroma, a central giant cell granuloma, and an aneurysmal bone cyst. Radiographic assessment was useful for forecasting the prognosis of a simple bone cyst. Possible reasons for the recurrence were discussed radiographically.

Traumatic bone cyst (TBC) occurs preferentially on the mandibular symphysis and body, but rarely on the mandibular condyle. When TBC occurs in the condylar area, it can usually be related with or misdiagnosed as a temporomandibular joint disorder. A 15-year-old female patient visited the Temporomandibular Joint Clinic with a 5-year history of pain and noise localized in the left temporomandibular joint. On imaging, a well demarked oval-shaped radiolucent lesion was observed on the left condyle head. The patient underwent cyst enucleation and repositioning of the bony window on the lateral cortex of the affected condyle head under the impression of subchondral cyst or TBC; however, no cystic membrane was found. The bone defect resolved and showed no recurrence on the serial radiographic postoperative follow-up for 43 months after surgery.

Most simple bone cysts are found in the metaphysis of the long bone, such as proximal humerus or proximal femur. Appropriate treatment is aspiration of the cyst followed by instillation of methylprednisolone or curettage with bone graft. We experienced 1 case of the simple bone cyst of the metatarsal bone. This case was treated by curettage and inserting allograft into the defect.

Introduction: Bone defects in the jaw are frequently observed after odontogenic cyst enucleation. The success of bone healing appears to be related to the size of the bone defect, the anatomical location, the patient's age and other parameters. The use of bone grafting material is dependent on the operator's preference. No evidence-based definite treatment protocol has been established. This study evaluated the effect of a bone graft into the defect after odontogenic cyst enucleation. Materials and Methods: A total of 55 patients, who had been treated for an odontogenic cyst with cyst enucleation from 2000 to 2009 at the department of Oral and Maxillofacial Surgery, Samsung Medical Center, were included in this study. Patients who were followed-up for more than 1 year were included. Two groups were defined according to the bone graft (with or without a bone graft) after cyst enucleation. The differences in the healing periods and patterns of bone healing were compared clinically and radiologically. The postoperative 1 year radiographs were analyzed for bone healing and density. Statistical analysis was performed using a Pearson chi square test and Wilcoxon rank-sum test. Results: More infection signs were observed in the bone graft group than in the other group, but there was no statistically significant difference. Radiographically, there was also no significant difference in the size of the radiolucent lesions between the two groups. Conclusion: There was no significant difference in healing between the groups with a bone graft and without bone graft after cyst enucleation.

This clinical study was made of 214 cases of the jaw cysts which were diagnosed histopathologically in the Department of Oral and Maxillofacial Surgery, Wonkwang University Dental Hospital from Jan. 1, 1991 to Dec. 31, 1998. Medical records, radiographs, histopathological reports of 214 cases with jaw cysts were retrospectively reviewed. The results were as follows : 1. Among the total patient of 214 cases, male were 143 cases, and female are 71 cases, male predominated by the ratio of 2.04. 2. The periapical cysts and the dentigerous cyst are the most common cyst, irrespective of 116 cases(54.2%) and 58 cases(27.1%). 3. The periapical cyst has no gender prediction, male were 70 cases and female were 54 cases, the mean ages were 39.3 years(SD=18.4). The most common involving teeth were maxillary anterior teeth(59.7%). 4. The dentigerous cyst predominantly occurred in third decade (18 cases : 31%), and the mean ages were 31.9 years(SD=14.8). Dentigerous cysts predominantly occurred in male by the ratio of 7.29 (male : 51 cases, female : 7 cases). Maxillary anterior teeth(43.1%) and mandibular molars(32.8%) were most frequently involved. 5. The odontogenic keratocyst predominantly occurred in second and third decade and mean ages were 23.5 years(SD=17.2). The mandibular molars(60%) were most frequently involved. 6. All nasopalatine cyst occurred after fourth decade, mean ages were 49.5years(SD=10.4). In the gender incidence of nasopalatine cyst, 1 case occurred in female and 10 cases occurred in male. 7. In the surgical intervention of jaw cyst, cyst enucleation and marsupialization performed in 156 cases. Cyst enucleation with bone graft performed in 58 cases and iliac autogenous bone grafts most frequently performed in 29cases. 8. The diameter range of cyst enucleation with bone graft were from 15mm to 120mm with a cyst diameter of 33.3mm. (SD=15.2) The diameter range of cyst enucleation and marsupialization were from 7mm to 82mm with a cyst diameter of 20.4mm.(SD=9.0) The diameter of cyst enucleation with bone graft were significantly greater than diameter of cyst enucleation. (p<0.05) 9. Post-operative complications occurred in 9 cases(15.5%) in which cyst enucleation with bone grafts performed and occurred in 31 cases(19.9%) in which cyst enucleation.

Aneurysmal bone cyst of the rib is a rare benign tumor which resembles the giant cell tumor or fibrous dysplasia of the bone. It rarely develops in the rib although it affects the metaphysis of the long bone and facial bone. We have treated a 14 year old male patient who had the aneurysmal bone cyst in the legt 4th. rib. Wide surgical resection of the affected rib was carried out with good clinical result. He is well 16 months after the resection.

This case series study demonstrates the possibility of successful implant rehabilitation without bone augmentation in the atrophic posterior maxilla with cystic lesion in the sinus. Sinus lift without bone graft using the lateral approach was performed. In one patient, the cyst was aspirated and simultaneous implantation under local anesthesia was performed, whereas the other cyst was removed under general anesthesia, and the sinus membrane was elevated in a second process, followed by implantation. In both cases, tapered 11.5-mm-long implants were utilized. With all of the implants, good stability and appropriate bone height were achieved. The mean bone level gain was 5.73 mm; adequate bone augmentation around the implants was shown, the sinus floor was moved apically, and the cyst was no longer radiologically detected. Completion of all of the treatments required an average of 12.5 months. The present study showed that sufficient bone formation and stable implantation in a maxilla of insufficient bone volume are possible through sinus lift without bone materials. The results serve to demonstrate, moreover, that surgical treatment of mucous retention cyst can facilitate rehabilitation. These techniques can reduce the risk of complications related to bone grafts, save money, and successfully treat antral cyst.

Purpose: The purpose of this study is to report the result of endoscopic assisted curettage and bone graft for the treatment of simple bone cyst in the calcaneus. Materials and Methods: Three cases in three patients who had curettage and bone graft of simple bone cyst in the calcaneus under endoscopic view were prospectively reviewed. A minimum follow-up of 1 year was required for entrance into the study. The results of treatment were clinically and radiologically assessed. Results: One case with preoperative heel pain gained complete relief of the pain at postoperative four weeks. All three cases had radiological union of grafted bone at an average of thirteen weeks after the operation. Shortened hospitalization and decreased postoperative pain were remarkable. Complications such as infection, skin necrosis, nerve injury, and, fracture were not seen. There was no evidence of the recurrence of the cyst in all three cases. Conclusion: Endoscopic assisted curettage and bone graft of simple bone cyst in the calcaneus is thought as an effective alternative procedure avoiding the possible complications of the classic method.

Twenty-nine cases of unicameral bone cyst developed in long bone of children have been treated and followed up for 4.5 years in average form Department of Orthopaedic Surgery, Guro Hospital, Korea University, College of Medicine since September, 1983, Treatment for those lesions differed to form largely two groups, one of which consised of insillation of Methyl-prednisolone for non-weight bearing bones(12 humeri) and the other of curettage and autogenous bone graft for weight-bearing bones(7 femur). Methl-prednisolone group required repetition of instillation for 3.5 time in average spanning over 4 years until cloudy obliteration occurs. Curettage and bone graft had healed in 3 year 6 months' time in average. There were neither recurrence nor pathologic fractures of the lesions with the latter group. Immobilization period was virtually non with Methyl-prednisolone group and 4-6 weeks by hip spica with curettage and bone graft group. As conclusions, It seems confirmed that treatment strategy of unicameral bone cyst consisted of Methyl-prednisolone instillation for humerus lesions and early curettage and bone graft for femur lesions is applicable as guideline having solid ground in clinical experiences.

Thyroglossal duct cyst is ectodermal remnant, which may develop along the line of descent of the thyroid gland from the foramen cecum of the tongue to the pyramidal lobe of the thyroid gland. Meticulous dissection of the cyst and duct, along with the body of the hyoid bone is necessary to avoid recurrence. Eighty-one patients with thyroglossal duct cyst treated at Hanyang University Hospital between January 1980 and December 2000 were reviewed to determine the incidence and to analyze the result of management. The male-to-female ratio was 1.4:1(47:34) with a male preponderance. They are most commonly present at 3-8years(54.2 %) of age, but rarely present at infancy. The most common symptom was a painless midline neck mass(76.5 %, 62cases). Eighty-one patients underwent modified Sistrunk operation without evidence of recurrence. Eight-nine percent(72 cases) of these lesions were located between thyroid substance and hyoid bone, and 11 %(9 cases) were above the hyoid bone. There were 22 infected cysts(27.2 %). The Sistrunk operation is a gold standard for treating the thyroglossal duct cysts. For best results in thyroglossal duct cyst surgery, one should make every effort to remove the cyst intact in continuity with the body of the hyoid bone. In our institute, Sistrunk operation modified by the authors showed a good result.
