ジャーナル フリーIn maxillofacial region, reconstruction of defects after inflammation, trauma, tumor resection and congenital anomaly should be functional and aesthetic. Meanwhile, recent approaches using regenerative medicine have shown great potential, enabling functionally and esthetically-satisfying reconstructions with less invasive manner. This review describes such regenerative medicine of bone in maxillofacial region, including transplantation of particulate cancellous bone and marrow (PCBM) in combination with a titanium mesh tray, and custom-made artificial bone (CT-Bone). Our preclinical and clinical study on tissue-engineered cartilage for patients with cleft-lip and nose is also covered.抄録全体を表示PDF形式でダウンロード (1227K) -

ジャーナル フリーOsseointegrated dental implants have become an accepted form of permanent tooth replacement since 1980s in our country. Factors important to successful osseointegration include the height, width, and angulation of the alveolar ridge; quality of bone at the implant site; and the relationship of the implant site to adjacent structures, such as the mandibular canal, maxillary sinus and nasal cavity. A major advancement in the preoperative evaluation of the dental implant patients is the development of computer software capable using computed tomography (CT) of generating such as multiple axial, cross-sectional, panoramic images and 3 dimensional image (3-D) of the jaw. This review discusses the fundamental understanding of CT and applications of CT software program for the dental implant treatment.抄録全体を表示PDF形式でダウンロード (1018K)

ジャーナル フリーOral verruciform xanthoma, first reported by Shafer in 1971, is a relatively rare benign lesion arising in gingiva or alveolar mucosa. We describe our experience with a case of verruciform xanthoma of the palate, which grew considerably during 17 years of follow-up. The subject was a 60-year-old man who presented with swelling of the left side of the palate in September 1989. Histopathological examination of a biopsy specimen showed verruciform xanthoma (size, 19 × 16 mm).
Although surgery was scheduled, the patient did not return to the clinic to undergo operation. In September 2006, the patient returned because of tumor enlargement. The tumor was pedunculated (size, 55 × 30 × 7 mm) with an irregular dark-red surface. Histopathological examination of a biopsy specimen taken in the same month revealed verruciform xanthoma, confirming the former diagnosis. The tumor was resected in November 2006, and the postoperative course was uneventful.抄録全体を表示PDF形式でダウンロード (903K) -

ジャーナル フリーRestriction of condylar movement anteriorly due to lesions of the articular eminence of the temporal bone is rare. In addition, to our knowledge, ossifying fibroma of this region has not been reported previously. We report a very rare case of ossifying fibroma of the articular eminence of the temporal bone. A 27-year-old man came to our hospital because of disturbance of mouth opening and pain of the left temporomandibular joint. Clinical examination showed that the maximum range of mouth opening was 25 mm. Disturbance of mouth opening had been present for about 7 months. Computed tomography revealed a 21 × 9 × 7 mm hard tissue lesion arising in the articular eminence of the temporal bone. The tumor was surgically excised with the patient under general anesthesia. The pathological diagnosis was ossifying fibroma. Three months after surgery, a residual or recurrent tumor developed. However, since the growth of tumor has been either slow or standstill, functional disorder of the temporomandibular joint has not developed as of 2 and a half years after operation.抄録全体を表示PDF形式でダウンロード (1020K) -

ジャーナル フリーBilateral chylothorax is a rare complication after radical neck dissection. We report a case of bilateral chylothorax that developed after left radical neck dissection. A 40-year-old man was given a diagnosis of secondary left cervical lymph-node metastasis from left-sided tongue cancer (T1N0M0), and supraomohyoid neck dissection was performed. Since multiple lymph-node metastases had been found, modified radical neck dissection was performed. We ligated the thoracic duct because it ruptured intraoperatively. On the first postoperative day, a chyle leak was diagnosed, and the thoracic duct was ligated again. The chyle leak resolved, but on the fourth postoperative day, the patient complained of dyspnea and chest discomfort. Computed tomographic scans and chest X-ray films showed bilateral pleural effusions. Diagnostic thoracentesis was performed. Milky fluid was aspirated, and chylothorax was diagnosed. We used a conservative management approach, which involved total parenteral nutrition with total enteric rest. Repeated chest X-ray films showed no evidence of pleural effusion, and the patient was started to receive a low-fat diet on the 11th postoperative day. The patient had recovered completely.抄録全体を表示PDF形式でダウンロード (856K) -

ジャーナル フリーArteriovenous malformation rarely occurs in mandibular bones. We describe our experience with a case of arteriovenous malformation arising in the mandible that could be completely extirpated surgically after transvenous coil embolization. A 10-year-old girl had left mandibular swelling, and slight but frequent bleeding from the left lower gingiva. The molars in the left mandible were unstable. Panorama X ray films, computed tomography, and magnetic resonance imaging showed the presence of an arteriovenous malformation approximately 5 cm in diameter, arising between the premolars and molars of the left mandible. After transvenous embolization with the use of a platinum coil (total 1800 cm), the mass of abnormal vessels and the lower premolars and molars with some adjacent tissue were surgically resected. Because the inferior border and lingual cortex of the left side of the mandible were sufficiently preserved, neither subsequent fixation with plates and screws nor reconstruction with a tissue graft was needed. The blood loss was 720 mL, and blood transfusion was not necessary. One year after surgery, there was no evidence of recurrence of arteriovenous malformation, and additional bone had newly formed from the resection margin of the mandibular bone.抄録全体を表示PDF形式でダウンロード (1035K)
