Treatment for cases with midface hypoplasia such as Apert syndrome and Crouzon syndrome should aim to achieve well-harmonized occlusion and maxillofacial morphology. To date, orthodontic treatments using Le Fort Ⅲ osteotomy concomitant with Le Fort Ⅰ or Ⅱ osteotomy have been reported. In this paper, we present a case with Apert syndrome treated by Le Fort Ⅲ distraction osteogenesis (LFⅢDO) followed by open rhinoplasty with iliac bone grafting and Le Fort Ⅰ osteotomy.The patient was a 16-year-old girl with Apert syndrome. She was characterized by severe midface hypoplasia representing skeletal Class Ⅲ occlusion with open bite. After the completion of preoperative orthodontic treatment, 12mm of midface advancement was performed by LF Ⅲ DO by using an internal distraction device. After the DO, although anterior open bite was slightly worse, midface hypoplasia and proptosis were significantly improved. Open rhinoplasty with iliac bone grafting was carried out 2 months after the LF Ⅲ DO. 5 months after the rhinoplasty, Le Fort Ⅰ osteotomy was performed to correct the anterior open bite.As a result, well-harmonized occlusion and maxillofacial morphology were achieved by close cooperation between the orthodontist, oral and maxillofacial surgeons and plastic surgeons.

The aim of this article is to discuss the effectiveness of clockwise rotation of the occlusal plane for skeletal class III deformities with the use of two-jaw surgery.The most popular orthognathic surgical management for class III malocclusion is mandibular setback using a bilateral sagittal splitting ramus osteotomy (SSRO). However, it has been suggested that, with the aid of an operative method using SSRO alone, complete elimination of the protruded appearance in the mental region is hardly attainable, in some cases. To obtain better functional and esthetic results for patients with class M deformities, clockwise rotation of the occlusal plane, using two-jaw surgery, appears to be considerably useful surgical management. The changes provided by an increased occlusal plane angle include 1) advancement of the midface; 2) rotation of the chin posteriorly; 3) a decreased maxillary incisor angle; 4) an increased mandibular plane angle; 5) decreased posterior facial height. We emphasize that, by appropriate usage of clockwiserotation of the occlusal plane, more favorable functional and esthetic results for the correction of skeletal class deformity will be enabled in some cases.

The accuracy of positioning the osteotomized maxilla during orthognathic surgery was assessed in 26 patients, comparing the use of an external reference point placed on the forehead skin (SERP), and an external reference point consisting of a bone screw placed at the forehead bone (BERP). In all cases, the unoperated mandible was used to provide an anteroposterior and transverse maxillary position, through use of an intermediate splint. In 14 cases, the distance between the SERP and the maxillary central incisor was measured, to determine the maxillary vertical dimensions. In 12 cases, measurements between the BERP the and maxillary central incisor were made.<BR>All preoperative lateral cephalometric radiographs were traced by one investigator, and these tracings were superimposed on postoperative lateral chephalograms (3 to 6 days after surgery), respectively. The actual changes in the vertical and horizontal position of U1 were measured perpendicular and parallel to the Frankfort horizontal plane. The actual change of the palatal plane angle was also measured. These values of actual change were compared with the prediction tracings made by measurements obtained from model surgery, and the difference between planned and actual movements was calculated.<BR>The mean difference of U1 anteroposterior movement was 1.5±2.0mm in the SERP group, and 1.2±1.1 mm in the BERP group. The mean difference of U1 vertical movement was 1.8 ±2.8mm in the SERP group, and 0.5±0.3mm in the BERP group. And the mean difference of palatal plane angle rotation in the SERP group was 2.7±6.2°, and 1.6±1.8° in the BERP group. Statistical analysis showed a significant difference between the SERP group and the BERP group in the U1 vertical difference (t-test, p<0.05).<BR>The results of this investigation revealed less accuracy in the actual three-dimensional maxillary movements of the SERP group, compared with the BERP group. And this study also showed that use of the BERP will allow accurate three-dimensional control of the maxillary position, especially in the vertical dimension. However, the maxillary repositioning technique using BERP still remains subject to operator error, and other numerous possible sources of error were identified, which may lead to an incorrect result.

1994年~1999年の6年間に,鶴見大学歯学部付属病院第一口腔外科ならびに関連施設で施行された顎裂部骨移植に関して臨床統計的観察を行った。その結果,以下のような結論が得られた。<BR>1)総患者数は86例で,11歳以下の症例が22例25.6%,12~17歳が32例37.2%,18歳以上の成人症例が32例37.2%を占めていた。<BR>2)生着率は97.7%で,早期経過不良の2例はいずれも成人症例であった。成人症例への対応として,骨移植後の感染源となり得る歯と歯周病の管理が重要と考えられた。<BR>3)受診の動機としては,顎裂に関する他科からの紹介が86例中80例93.0%で,そのうち矯正歯科からの紹介が最も多く72.5%であった。一方,当初他疾患を主訴に来院したものが6例あり,いずれも顎裂部骨移植に関する知識は皆無であった。今後,関連各科との連携強化と患者への積極的な情報提供が必要と考えられた。<BR>4)顎裂部骨移植に関連する併用手術としては,顎矯正手術のほか,デンタルインプラントの埋入,口唇外鼻修正術などが,主に成人症例に対して施行されており,成人症例における顎裂部骨移植の臨床的意義が示唆された。

The aim of this study was to clarify the factors which influenced the successful of bony bridging following bone grafts into the alveolar cleft with autogenous particulate cancellous bone harvested from iliac bone.<BR>The bone bridge build up in the alveolar cleft was assessed by periapical radiographs taken before and 18-23 months after the operation. Successful bony bridging defined as a bone bridge with a vertical height of greater than about 11mm, was observed in 123 of all 202 clefts. The frequency of successful bony bridging decreased with increasing severity of cleft type. Successful bony bridging was achieved in 81.8% of unilateral cleft lip and alveolus patients and in only 45.2% of bilateral cleft lip and palate patients. Moreover, the frequency of successful bony bridging was significantly negatively correlated with the width of the cleft. The present study has clearly shown at least two major determinants of successful bony bridging: 1) the cleft type, and 2) the width of the cleft.
