Purpose: The aims of this study were to measure the distance of the intraosseous vascular anastomosis in the anterolateral wall of the maxillary sinus from different reference points, and to correlate the location of the intraosseous vascular anastomosis with the tooth position and the residual bone height of the maxilla. Methods: Computed tomography (CT) images were taken from 283 patients undergoing dental implants placement in the posterior maxilla. Three horizontal lines were drawn at the ridge crest, maxillary sinus floor, and the position of the anastomosis. A vertical second line at the center of each tooth was drawn perpendicular to the horizontal lines. The distance from the ridge crest to the maxillary sinus floor and the distance from the maxillary sinus floor to the bony canal were measured from the intersections of the horizontal and vertical lines. The residual alveolar bone height was used to categorize three groups: group 1,<4 mm; group 2, between 4 and 8 mm; and group 3, >8 mm. Results: The residual bone height values of different tooth positions were significantly different (P=0.0002). The distance from the maxillary sinus floor to the intraosseous vascular anastomosis was significantly different between groups 1 and 3 (P=0.0039). At the molar sites, a moderate negative correlation was found between the residual bone height and the distance from the maxillary sinus floor to the intraosseous anastomosis. The distances of the alveolar ridge crest and the maxillary sinus from the intraosseous vascular anastomosis were not significantly different between sexes. Conclusions: Within the limitations of this study, sites with a higher residual bone height in the molar regions were at a relatively high risk of artery damage during window osteotomy preparation; therefore, we recommend taking more precautions when using a lateral approach for sinus elevation.

Mucoepidermoid carcinoma generally arises from salivary glands and represents 5~10% of all salivary tumors. Arising within the jaws as primary central bony lesions, central mucoepidermoid carcinomas are extremely rare, accounting for only 2~3% of all mucoepidermoid tumors. Central mucoepidermoid carcinoma of the mandible was first reported in 1939 and since then approximately 100 cases have been documented in the literature. Several hypotheses have been proposed to explain the pathogenesis of intraosseous salivary tumors. The most likely source of most intraosseous tumors is odontogenic epithelium. Waldron and Mustoe suggested that central mucoepidermoid carcinoma be included in primary intraosseous carcinoma of the jaw. We report here on a case of central mucoepidermoid carcinoma affecting the mandible and discuss the clinical, radiographic, and histological findings.

We report on a rare case of an intraosseous epidermoid cyst in the distal phalanx of the great toe with concurrent infection in a 71-year-old woman with diabetes mellitus. The lesion was initially considered simple infectious arthritis and concomitant osteomyelitis in a patient with diabetes. However, after surgery, an intraosseous epidermoid cyst originating from the nail bed and involving the articular surface of the distal phalanx was detected. The epidermoid cyst may have contributed to the infectious arthritis in the interphalangeal joint. The lesion was treated via mass excision, arthrotomy, debridement, and intravenous antibiotics.

Intraosseous lipoma is a benign tumor that originates from proliferating mature lipocytes. It often occurs in the metaphysis of long bones of the lower extremity, and also in the calcaneus, humerus, mandible, sacrum, and rib bones. Frequently, it involutes spontaneously through a process of infarction, calcification, and cyst formation. It can either present as pain, or be asymptomatic and only discovered through an incidental radiological finding. In our case, the patient presented with heel pain. Intraoperatively, it was found that the intraosseous cavity was filled with fat along with an adjacent but separate area of cystic degeneration. There was also a cortical perforation at the cystic lesion which was communicating with the subtalar joint. This cortical breach is most likely the cause of diffuse lateral heel pain experienced by our patient, and such a pathological fracture due to intraosseous lipoma has never been reported.

Intraosseous hemangioma is a rare, slow-growing, benign tumor of blood vessels. Primary hemangioma of the skull is a benign lesion that may appear as a palpable mass or accidentally detected during image evaluation. Simple radiography is the most commonly used technique to localize a lesion and computed tomography (CT) may help determine the effect of a lesion. We report a case of multifocal intraosseous calvarial hemangioma developed in the subgaleal plane of an elderly male patient. Ultrasonography examination revealed hyperechoic striated septae parallel to the skin and discontinuity of the focal cortex, however, the underlying bone cortex appeared relatively intact. No significant flow is observed on Doppler ultrasonography. Based on these evaluations, the mass was interpreted by a radiologist as a subgaleal lipoma. This case highlights the importance of additional CT examination in a patient presenting with a scalloping sign of the underlying calvarium. Clinicians also should be aware of the possibility of intraosseous calvarial hemangiomas in lesion. Furthermore, the proper choice of congenital vascular malformation term is still quite confusing with misconception present in the literature.

Complete surgical excision within a margin of normal healthy bone is the treatment of choice for intraosseous hemangioma. A 56-year-old man visited with complaints of a firm, mildly tender, immovable, and palpable mass on the right forehead (size: 1.5×1.5 cm). Non-contrast brain computed tomography performed preoperatively revealed a 1.5 cm heterogenous osteolytic lesion with suspected internal trabeculation in the right frontal bone. Under general anesthesia, a 2 cm transverse incision was made on the forehead skin rather than bicoronal incision. Full-thickness en bloc resection of the frontal bone including the mass was performed. The frontal bone was removed with care taken not to damage the frontal sinus mucosa. The frontal sinus was sealed with a collagen patch (Tachocomb) and a cranioplasty was performed using bone cement. At 6 months postoperative, a clean wound was confirmed without any complications, and there was no local recurrence. Surgical excision of intraosseous hemangioma in the frontal sinus bone can be performed via direct incision or the bicoronal approach. In this case, the direct incision approach was used to achieve smaller scars and faster recovery than the bicoronal approach.

Purpose: Intraosseous hemangiomas are rare and account for fewer than 1% of all bone tumors. The site that is most commonly involved are the vertebral column and the skull. Within the facial skeleton, hemangiomas can occur in the mandible, maxilla, the nasal bones, and rarely the zygoma. Methods: We report a case of an intraosseous hemangioma of the zygoma in a 49-year-old male. The patient had a slow growing hard mass in the left zygoma, which had been present for 8 years. Other than the cosmetic deformity, the patient experienced no pain and did not have any problem. He had no history of trauma in that area and no ocular symptoms. Preoperative computed tomography showed a trabeculated mass arising from the body of the left zygoma. The mass was surgically removed without having to reconstruct the bone defect by spairing the inner cortex. Results: Histopatholgical examination indicated a cavernous hemangioma. After 4 months of follow up, no functional and cosmetic impairment was identified. The patient was satisfied with the result. Conclusion: An intraosseous hemangioma of the zygoma can be treated with total surgical excision with preservation of the inner cortex, thus eliminating the need for reconstruction of bone defect.

판사이 동정맥루(diploic arteriovenous fistula) 혹은 골내 동정맥루(intraosseous arteriovenous fistulas)는 동정맥 단락의 한 형태로 드물게 발생한다. 판사이 동정맥루에서 누공은 뇌막동맥(meningeal artery)과 골내 판사이 정맥(intraosseous diploic vein) 혹은 이끌정맥(emissary vein) 사이에 형성되고, 누공의 핵은 골내에만 위치한다. 현재, 경막 동정맥루에 대한 대표적 치료 방법은 혈관내 색전술로 대부분이 대퇴동맥/대퇴정맥을 통하여 접근한다. 하지만 혈관내 색전술 시 접근 가능한 통로가 없는 경우에는 대체할 수 있는 다른 접근법을 고려해야 한다. 우리는 이번 증례에서 두개골내 판사이정맥을 직접 천자하여 혈관내 색전술로 치료된 판사이 동정맥루 증례를 보고하고자 한다.
