Purpose: Gaining vascular access is difficult and time-consuming in critically ill children, so nowdays, in many countries, intraosseous vascular access is frequently used for rapid vascular access in critically ill children. Its pharmacokinetics is close to that of the peripheral intravenous route, but its infusion flow rate is faster. The purpose of this study was to determine how widely the intraosseous infusion technique was being used in Korean emergency departments. Methods: We telephoned forty-two (42) randomly selected university-affiliated hospitals. We asked physicians if they use the intraosseous infusion technique. Responders were emergency and pediatric residents and emergency faculty. If they responded that they were not using the intraosseous infusion technique, we asked the reason. Also, we asked about their experiences with the intraosseous infusion technique. Results: Forty-two (42) hospitals were enrolled in this study. No hospital used the intraosseous infusion technique on a regular basis. However, 8 hospitals used the intraosseous infusion technique occasionally. None of the responders had experience with the intraosseous infusion technique. Conclusion: The intraosseous infusion technique is currently underrepresented at emergency departments in Korea.

The WHO separates odontogenic carcinomas into three groups : malignant ameloblastoma, primary intraosseous carcinoma(PIOC), and carcinomas arising from odontogenic epithelium including those arising from odontogenic cysts. In WHO criteria, primary intraosseous carcinoma is defined as a squamous cell carcinoma arising within the jaw, having no connection with the oral mucosa, and no developing from residues of odontogenic epithelium. This is a case of 52-year old man who had prolonged jaw pain and final diagnosis was primary intraosseous carcinoma(PIOC) on mandible. We obtained successful result after composite resection combined with hemimandibulectomy, RND, following reconstruction with latissmus dorsi myocutaneous flap, and postoperative radiation therapy.

Intraosseous lipoma is rarely reported in the literature, despite the fact that lipocytes are found as normal components of medullary bone. It is a primary bone tumor that originate from within the medullary cavity. The incidence of intraosseous lipoma has been reported as less than one per thousand bone tumor. The authors experienced a patient who had the findings of bilateral intraosseous lipoma of the calcaneus. We report a case of bilateral intraosseous lipoma of the calcaneus with brief review of literature.

Intraosseous carcinoma of the jaw may arise as metastatic lesions most commonly from breast, lung, kindney and thyroid and also primarily occur from ameloblastoma or odontogenic cyst. Rarely primary intraosseous carcinoma could be originated from the epithelium involved in odontogenesis. According to WHO's classification, primary intraosseous carcinoma is defined as squamous cell carcinoma, occured in the Jaw without connection to the oral mucosa. However, Elzay defined primary intraosseous carcinoma as malignant epithelial tumor related to the odontogenic apparatus, including carcinoma ex-odontogenic cyst, carcinoma ex-ameloblastoma and carcinoma de novo. We experienced 2 cases of intraosseous carcinoma of the jaw. The first case, a 59-year-old man, showed a ill-defined mass on the left maxilla, measuring $8{\times}10cm$ in size. He received radical hemimaxillectomy and was diagnosed as ameloblastic carcinoma. The second case obtained from a 79-year-old woman showed a ill-defined $6{\times}8cm$ sized mass on the left mandibular body area. The mass was surgically removed by partial mandibulaectomy, which was diagnosed as the primary intraosseous carcinoma, probably odontogenic origin.

A case of spinal intraosseous schwannoma (SIS) in the lumbar vertebra is reported. Clinical and radiologic characteristics of 16 reported cases of SIS were reviewed. SIS can be a rare differential diagnosis for intraosseous tumors.

Benign intraosseous osteolytic lesions of the glenoid are very rare. The present study reports on three cases of symptomatic intraosseous osteolytic lesions of the glenoid in which surgical interventions were made. Of the three, two cases presented with intraosseous ganglion and one case with fibrous dysplasia. In all the cases, the lesion was located at the posteroinferior portion of the glenoid, and it seems to be related to posterior shoulder pain. If intraosseous osteolytic lesions have symptoms or the risk for chondral defects or cortical breakage, surgical intervention is needed and bone curettage with or without bone grafting will be a useful treatment option.

Intraosseous vascular lesions of the maxillofacial region are rare, and the differential diagnosis of intraosseous vascular malformations from other jaw lesions can be challenging. In the present case, magnetic resonance imaging and three-dimensional computed tomographic angiography (CTA) was used for diagnosis, and the lesion was treated wih surgical excision. Diverse characteristics such as the "honeycomb" and "sunburst" radiographic appearances and the absence of major peripheral feeder vessels in the CTA were noted. Intraosseous vascular malformations have a varied radiographic appearance, and the nomenclature of these lesions is equally diverse, with several overlapping terms. Pathologists do not generally differentiate among intraosseous vascular lesions on the basis of histopathology, although these lesions may present with contrasting immunohistochemical and clinical behaviors requiring varied treatment strategies. This case report highlights the need for multiple imaging modalities to differentiate among vascular lesions, as well as to better understand the behaviors of these unique lesions.

Intraosseous ganglion is a benign cystic lesion. It is composed of fibrous tissue with mucoid changes located in the subchondral bone adjacent to a joint. Intraosseous ganglion has been reported in various skeletal sites and most commonly in the lower end of the tibia and femur. However reports of intraosseous ganglion of the glenoid are rare, with only 14 cases in the literature. We repot 2 cases of intraosseous ganglion of the glenoid with literature reviews.

Benign cystic lesions, have to be differentiated, are common in the calcaneus, Among the lesions the intraosseous lipoma is extremely rare tumor in bone. In 1996, Unni reported 7 in 11,087 cases of bone tumors at Mayo Clinic. In Korea, Ahn reported the first intraosseous lipoma in the distal fibula. We experienced two cases of intraosseous lipoma of calcaneus, and report the clinical, radiological and pathological findings with a review of the literatures.

Intraosseous hemangioma is an extremely rare tumor that accounts for 1% or fewer of all osseous tumors. The most common sites of its occurrence are the vertebral column and calvaria. Occurrence in a facial bone is very rare. The authors aim to report a case of the surgical treatment of intraosseous hemangioma occurring in the periorbital region, which is a very rare site of occurrence and to introduce our own experiences with the diagnosis and treatment of this condition along with a literature review. A 73-year-old male patient visited our hospital with the chief complaint of a mass touching the left orbital rim. A biopsy was performed by applying a direct incision after local anesthesia. Eventually, intraosseous hemangioma was diagnosed histologically. To fully resect the mass, the orbital floor and zygoma were exposed through a subciliary incision under general anesthesia, and then the tumor was completely eliminated. Bony defect was reconstructed by performing a seventh rib bone graft. Follow-up observation has so far been conducted for 10 months after surgery without recurrence or symptoms.
