ジャーナル フリーThough it is hard to say the distraction osteogenesis of the jaw bone is a standard therapy for the patients with jaw deformity, the distraction osteogenesis of the jaw bone is becoming one of the popular techniques for treatment of jaw deformity. Specially, maxillary distraction is an effective method for improving the hypoplasia of the midface （dish face） derived from cleft deformity. In this review, the basic concept of the maxillary distraction is mentioned first. Then, the standard method of the maxillary distraction using the rigid, external, distraction （RED） system is described in detail. In addition, since a rather rigid internal device for maxillary distraction has been fabricated recently, this internal device is introduced. A case undergoing maxillary distraction using this internal device is also shown. The tricks and attention during the maxillary distraction using those external and internal devices are stated from the author’s experience. The advantage and disadvantage of the distraction techniques using those external and internal devices are discussed further. Then the problems of the present maxillary distraction are discussed.抄録全体を表示PDF形式でダウンロード (691K) -

ジャーナル フリーOrthognathic surgery is considered to be the principal tool for correcting dentofacial deformity. The goal of this procedure is to achieve functional occlusion and favorable profile. Segmental maxillary osteotomies and subapical mandibular osteotomies are commonly indicated in correction for dentofacial deformities in which only a portion of the dentoalveolar arch requires repositioning for functional and esthetic reasons. These procedures are divided into four types: anterior or posterior segmental maxillary osteotomies and anterior or posterior subapical mandibular osteotomies. Although the use of these osteotomies has been decreasing due to improvements in orthodontic treatment techniques and other surgical techniques, these procedures are useful for patients with dentoalveolar deformities and are also frequently used in combination with other jaw surgeries. For clinical success in these osteotomies, it is necessary to achieve good mobilization of the segments to allow for passive repositioning in the predetermined position and to maintain optimal vascularity to mobilized segments and avoid damages to teeth, periodontal tissue and nerve tissue.抄録全体を表示PDF形式でダウンロード (638K)

ジャーナル フリーWe describe the case of a glomus tumor arising in the upper lip of a 72-year-old Japanese man. The patient had had a tender swelling in his upper lip since 2004, but ignored the symptoms. In 2010, a growth was noticed when he underwent dental treatment at a local dental clinic; he subsequently visited our hospital for an examination. We found a smooth-surfaced, soft, elastic tumor, 13 mm in diameter and dark purple, on the upper lip. T1-weighted magnetic resonance imaging revealed a mass with the same signal intensity as muscle. T2-weighted imaging showed a slightly higher signal intensity than that of muscle. The mass was clinically diagnosed to be a benign tumor of the upper lip and was completely excised with the patient under sedation with an intravenously administered anesthetic. The histopathological diagnosis was a glomus tumor. Hematoxylin and eosin staining showed a well-defined tumor with perivascularity and a large number of blood vessels of various sizes. Both ovoid and short fusiform tumor cells had proliferated to form a solid tumor. Immunohistochemically, the tumor cells were positive for alpha-smooth muscle actin, h-caldesmon, and CD34 but negative for S-100, desmin, and cytokeratin. The tumor cells were also negative for AE1/AE3. A postoperative examination at 1 year suggested a good prognosis with no signs of recurrence.抄録全体を表示PDF形式でダウンロード (871K) -

ジャーナル フリーGlandular odontogenic cyst （GOC） is rare odontogenic cyst, first described by Gardener et al. in 1988. We report a case of GOC arising in the maxilla. The patient was 57-year-old man who presented with pain and swelling of the right canine region of the maxilla. Panoramic radiography showed a clearly bordered radiolucent region extending from the canine to premolar region of the maxilla. The clinical diagnosis was a radicular cyst of the canine teeth, and enucleation and tooth extraction were performed with the patient under general anesthesia. The histopathological diagnosis was GOC. As of 12 months after discharge, there has been no evidence of recurrence.抄録全体を表示PDF形式でダウンロード (582K) -

ジャーナル フリーAsystole or bradycardia due to trigeminocardiac reflex is a rare complication of oral and maxillofacial surgery. We report a case of bradycardia during orthognathic surgery.
An 18-year-old woman with retrognathia underwent Le Fort I osteotomy, sagittal split ramus osteotomy, and genioplasty. However, preoperative electrocardiography revealed mild bradycardia. The results of blood examinations and chest radiography were within normal limits. After genioplasty had been done, bradycardia developed suddenly while suturing the mandibular mucoperiosteal flap. Surgery was immediately discontinued; cardiac massage was started, and atropine was administered intravenously. About after 20 seconds, the heart rate recovered to the normal range. No further episode of bradycardia was encountered, and the operation was finished as scheduled. We supposed that bradycardia was caused by traction of the mental nerve.
Oral and maxillofacial surgeons should be aware of the possibility of trigeminocardiac reflex during operation.抄録全体を表示PDF形式でダウンロード (479K) -

ジャーナル フリーVarious methods are used for reconstruction in patients with traumatic facial palsy. We describe facial nerve dynamic reconstruction for severe traumatic facial palsy in a 42-year-old man. His face was cut by an electric lawn mower. Two years later, a hypoglossal nerve-facial nerve anastomosis was peformed to treat facial nerve palsy. We used the great auricular nerve for bypass grafts, and jump grafts for end-to-end anastomoses with the facial nerve and with the hypoglossal nerve. Seven months after reconstructive surgery, facial palsy had improved to grade III according to the House-Brackmann method.抄録全体を表示PDF形式でダウンロード (540K)
