This report describes a case of successful orthodontic treatment using maxillary anterior segmental distraction osteogenesis with an internal maxillary distractor and bilateral sagittal split ramus osteotomy in a girl with cleft lip and palate. A 16-year-old girl with unilateral cleft lip and palate exhibited midface retrusion because of growth inhibition of the maxillary complex and mandibular excess. After the presurgical orthodontic treatment, 6.0-mm advancement of the maxillary anterior segment and 4.0-mm set back of the mandible were performed. After a retention period, the patient's midface convexity was greatly improved and the velopharyngeal competence was preserved without relapse.

Odontogenic tumors and cysts, arising in the jawbones, grow by resorption and destruction of the jawbones. However, mechanisms underlying bone resorption by odontogenic tumors/cysts remain unclear. Odontogenic tumors/cysts comprise odontogenic epithelial cells and stromal fibroblasts, which originate from the developing tooth germ. It has been demonstrated that odontogenic epithelial cells of the developing tooth germ induce osteoclastogenesis to prevent the tooth germ from invading the developing bone to maintain its structure in developing bones. Thus, we hypothesized that odontogenic epithelial cells of odontogenic tumors/cysts induce osteoclast formation, which plays potential roles in tumor/cyst outgrowth into the jawbone. The purpose of this study was to examine osteoclastogenesis by cytokines, focusing on transforming growth factor-beta (TGF-beta), produced by odontogenic epithelial cells. We observed two pathways for receptor activator of NF-kappa B ligand (RANKL) induction by keratocystic odontogenic tumor fluid: the cyclooxygenase-2 (COX-2)/prostaglandin E2 (PGE2) pathway through interleukin-1 alpha (IL-1 alpha) signaling and non-COX-2/PGE2 pathway through TGF-beta receptor signaling. TGF-beta 1 and IL-1 alpha produced by odontogenic tumors/cysts induced osteoclastogenesis directly in the osteoclast precursor cells and indirectly via increased RANKL induction in the stroma.

CLEFT PALATE-CRANIOFACIAL JOURNAL 53 ( 4 ) 491 - 498 2016.7

Language：English Publishing type：Research paper (scientific journal) Publisher：ALLIANCE COMMUNICATIONS GROUP DIVISION ALLEN PRESS

The present report describes a male patient with a unilateral cleft lip and palate who presented with midfacial anteroposterior and transverse deficiency. Correction involved a two-stage surgical-orthodontic approach: asymmetric anterior distraction of the segmented maxilla followed by two-jaw surgery (LeFort I and bilateral sagittal splitting ramus osteotomies). The present case demonstrates that the asymmetric elongation of the maxilla with anterior distraction is an effective way to correct a transversely distorted alveolar form and midfacial anteroposterior deficiency. Furthermore, successful tooth movement was demonstrated in the new bone created by distraction.

Objective: 1,4-Dihydroxy-2-naphthoic acid (DHNA) is the main component of the metabolic products after fermentation by Propionibacterium freudenreichii ET-3. In this study, DHNA, vitamin K2 (VK2), and risedronate (Ris) were administered to ovariectomized (OVX) mice to ascertain their suppressive effects on bone mass reduction. Methods: Fifty mice were divided into five groups: Sham, OVX, DHNA, VK2, and Ris groups. The drugs were administered daily for 8 weeks. Subsequently, blood was collected from the orbital venous plexus. The bilateral femurs and L5 lumbar vertebra were excised. To determine the effects of the drugs, we performed histomorphometric analyses of the left femur and L5 by micro-CT, biochemical analyses of serum samples, and histological analyses of the right femur. Results: The results for the total bone mineral density, bone volume density, trabecular thickness, trabecular number, trabecular separation, and histological analyses showed that bone resorption was improved in the DHNA and Ris groups compared with the OVX group. Furthermore, the biochemical analyses revealed that the production of inflammatory cytokines was suppressed in the DHNA and Ris groups. Conclusions: The present findings show that DHNA suppresses the bone mass reduction in OVX mice, suggesting that it could be an alternative treatment for postmenopausal osteoporosis.

Objective: The antilingular prominence (AP) is a well-known landmark used during planning of intraoral vertical ramus osteotomy (IVRO) in order to prevent inferior alveolar nerve (IAN) injury, but the location of this landmark is not always clear. In this study, we analyzed the anatomical relationship between the mandibular foramen (MF) and the lateral surface shape of the mandibular ramus for use during IVRO.Patients and methods: We retrospectively analyzed 276 mandibular halves in 67 patients with mandibular deformity and 71 patients without deformity imaged at our department from April 2003 to March 2014. We defined 17 points on the mandibular ramus, and examined the anatomical relationships using multiplanar reconstruction (MPR) images and three-dimensional computed tomography (3DCT) created from preoperative CT data.Results: The prevalence of the AP was 57.6% (159/276) of all cases. The MF was located inferior to the AP in all cases; it was posterior to the AP in 50.3% (80/159) of cases and the sigmoid notch (SN) in 24.6% (68/276) of cases. The minimum horizontal distance between the mandibular posterior ramus border and the MF was 9.28 mm in all cases.Conclusion: The AP cannot always serve as a reference point to prevent IAN damage during IVRO. The osteotomy incision should be placed within 9 mm of the posterior mandibular ramus border in order to prevent intraoperative IAN damage. However, preoperative review of planned osteotomy incisions is necessary in every case. (c) 2014 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI. Published by Elsevier Ltd. All rights reserved.

This case report presents the management of a female patient with unilateral cleft lip and palate presenting with skeletal Class III malocclusion and a narrow upper dental arch with a midline deviation. The treatment plan involved asymmetric transverse distraction osteogenesis of the maxilla to make the upper dental midline coincident with the facial midline. After the treatment, a good facial profile and a close intercuspation of teeth were achieved. Occlusion remained stable with normal overjet and overbite after 2-year retention.

Maxillary Advancement for Unilateral Crossbite in a Patient with Sleep Apnea Syndrome Reviewed

ACTA MEDICA OKAYAMA 69 ( 3 ) 177 - 182 2015.6

Language：English Publishing type：Research paper (scientific journal) Publisher：OKAYAMA UNIV MED SCHOOL

This article reports the case of a 44-year-old male with skeletal Class III, Angle Class III malocclusion and unilateral crossbite with concerns about obstructive sleep apnea syndrome (OSAS), esthetics and functional problems. To correct the skeletal deformities, the maxilla was anteriorly repositioned by employing LeFort I osteotomy following pre-surgical orthodontic treatment, because a mandibular setback might induce disordered breathing and cause OSAS. After active treatment for 13 months, satisfactory occlusion was achieved and an acceptable facial and oral profile was obtained. In addition, the apnea hypopnea index (AHI) decreased from 18.8 preoperatively to 10.6 postoperatively. Furthermore, after a follow-up period of 7 months, the AHI again significantly decreased from 10.6 to 6.2. In conclusion, surgical advancement of the maxilla using LeFort I osteotomy has proven to be useful in patients with this kind of skeletal malocclusion, while preventing a worsening of the OSAS.

SAWAKI Koichi, OKAZAKI Fumihiko, SATO Aki, NAKANO Makoto, TAKAGI Shin, IIDA Seiji

Journal of Oral Surgery Society of Japan 61 ( 3 ) 168 - 172 2015

Language：Japanese Publisher：Japanese Society of Oral and Maxillofacial Surgeons

Mesothelioma is a rare neoplasm that arises from the pleura or peritoneum. Although malignant mesothelioma is known to spread hematogenously, causing metastasis to various organs, there have been few reports on oral metastasis. The patient was a 75-year-old man who had an elastic soft mass, measuring 38 × 20 mm, in the right upper jaw gingiva. On biopsy the lesion was histopathologically diagnosed as a malignant pleural mesothelioma with metastasis to the upper jaw. The lesion shrank in response to radiotherapy. We have described a case of malignant pleural mesothelioma arising in the upper jaw gingiva. We discuss the related literature and summarize our findings.
