  • This case was diagnosed as multiple cementoosseous dysplasia on the basis of clinical & radiological features but was diagnosed as ossifying fibroma on the basis of histopathological feature. The histopathologic features of the multiple cementoosseous dysplasia and cementoossifying fibroma have common features of cementum, fibrous network and bone. Multiple cementoosseous dysplasia is reactive lesion and shows restricted lesion size, occurred on anterior and posterior tooth of the mandible and needs no treatement except periodic follow up. But Cementoossifying fibroma is the true neoplasm and grows continuously and needs surgical removal. The final diagnosis of the multiple cementoosseous dysplasia requires good correlation of the clinical, histopathological, and radiological features.

  • Familial gigantiform cementoma is a rare fibre-cemento-osseous disease of the jaws which appears to be transmitted as an autosomal dominant trait with variable expressivity of the phenotype. A 7-year-old girl visited DKUDH complaining of the painless facial deformity. Clinically, significant facio-lingual expansion was observed at the left maxilla, left mandibular body and symphysis portion. Malposition of lower anterior teeth was found. Panoramic radiograph and CT scan showed the extensive expansile mixed lesion at maxilla and mandible. Bone scan revealed hot spot at the maxilla and left side of mandible. Histologic examination revealed moderately dense fibrous connective tissue with scattered masses resembling cementum. The patient's mother had a history of the mandibular resection due to benign tumor. Her younger brother had buccal expansion of right mandible. We report our finding of a family that has exhibited clinical, radiographic and histologic findings consistent with the familial gigantiform cementoma.

  • Herein, we report and discuss the detection of fossa navicularis magna, a close radiographic anatomic variant of canalis basilaris medianus of the basiocciput, as an incidental finding in cone-beam computed tomography (CBCT) imaging. The CBCT data of the patients in question were referred for the evaluation of implant sites and to rule out pathology in the maxilla and mandible. CBCT analysis showed osseous, notch-like defects on the inferior aspect of the clivus in all four cases. The appearance of fossa navicularis magna varied among the cases. In some, it was completely within the basiocciput and mimicked a small rounded, corticated, lytic defect, whereas it appeared as a notch in others. Fossa navicularis magna is an anatomical variant that occurs on the inferior aspect of the clivus. The pertinent literature on the anatomical variations occurring in this region was reviewed.

  • Benign fibro-osseous lesions occur when normal bone is replaced by cellular fibrous connective tissue and mineralized structures. One rare type of these lesions is the ossifying fibroma (OF). The aim of this study is to report an unusual case of OF in a 57-year-old female. Physical examination showed facial asymmetry without any tenderness, fluctuation, ocular pain, or ophthalmoplegia. Imaging exams revealed a solid mass involving the left maxilla and orbital floor. Surgical resection was performed without any complications or sequelae, and the histopathological results confirmed OF. Although recurrence is rare in this condition, the patient remains under follow-up.

  • One of the most difficult airway problems is a subglottic stenosis combined with a tracheal stenosis. Laryngotracheal stenosis has not been completely solved with classic methods like cricotracheal split with autogenous cartilage graft, thyrotracheal anastomosis, and free hyoid or hyoid-sternohyoid myo-osseous flap reconstruction. A 28-near-old male patient who had had laryngotracheal stenosis was successfully treated by laryngotracheal reconstruction using vascularized clavicle. This method has a several advantages: the vascularized clavicle harvesting in the same operative fields, one stage operation, less restenosis due to plentyful blood supply, md prevention of airway collapse due to a clavicle provided framework. It is too early to make a definite conclusion, but the authors suggested that this method could become one of the most effective methods of laryngotracheal stenosis.

  • A case of a peroneal nerve palsy caused by repeatedly recurred intraneural ganglion cyst is presented. A 19 year old male suffered from tingling sensation on the foot dorsum more than one year and underwent two times of mass excision and nerve palsy was recorvered. But it was recurred once more after 10 months after the second excision. The mass was located in the fibro-osseous tunnel against the fibular neck and the origin of the peroneus longus. The third complete excision was done and full recovery was obtained in 6 months.

  • Major technologic advances in fiberoptic light transmission, video cameras, and instrumentation have allowed great advances in small-joint arthroscopy. Arthroscopy in particular is now well established procedure for accurate diagnosis and operative management of certain ankle disorders. The small size of the ankle and significant periarticular soft tissue structures make placement and advancement of the arthroscope and instrumentation more difficult than in larger joints. Successful arthroscopy of the ankle requires knowledge of the regional anatomy and a familiarity with the available arthroscopic portals. This review article is going to describe the gross and arthroscopic anatomy of the ankle as it relates to current arthroscopic techniques. Particular emphasis is placed on the anatomic relations of the important osseous and soft tissue structures for a safe, reproducible approach to arthroscopic treatment of ankle pathology. Also, current arthroscopic equipment and instruments are included.

  • Uptake of $^{99m}Tc$ bone-scanning agents by extra osseous tissues has been frequently reported. However, lung and stomach uptake of $^{99m}Tc$ bone-scanning agents in lymphoma has been rarely described. We report here a case with lymphoma and hypercalcemia which showed diffuse uptake of $^{99m}Tc-MDP$ by lung and stomach.

  • The C2 level is the transition zone between the cranial and cervical spine. Because of its high position and anatomic relationship to vital structures, exposing C2 is challenging and the surgical approach is controversial. We report a of a recurred chordoma in C2 portion, occupying the osseous intraspinal portion. The patient underwent total corpectomy of C3 and gross total removal of tumor by right submandibular approach 3 years previously. We performed a lateral extrapharyngeal approach from contralateral left side with resection C2 central portion followed by gross total removal of mass and placement of graft bone. Although there was transient hypoglossal nerve palsy postoperatively, the patient had full recovery.

  • Tracheobronchopathia osteochondroplastica (TO) is a rare idiopathic tracheobronchial abnormality characterized by diffuse cartilaginous and osseous nodules protruding into the airway lumen of the trachea and bronchus. TO is easy to misdiagnose because of nonspecific symptoms and chest CT scan with pathologic biopsy is necessary for definitive diagnosis. We report two cases of patient with TO who underwent laryngomicroscopic biopsy and tracheostomy with literature review.
