A case of mandibular prognathism with Marfan's syndrome treated with sagittal splitting ramus osteotomy was presented.A 37 year-old man, complaining of difficulty of mouth opening was referred to our clinic. The patient was diagnosed as bilateral temporomandibular joints arthrosis with mandibular prognathism.Although occlusal treatment with bite splint was effective to some extent, intermittent trismus did not disappear, so bilateral sagittal splitting ramus osteotomy was performed to correct his dental malocclusion.Postoperative course was not eventful and his range of mouth opening increased to 35mm between incisal edges of maxillary and mandibular central incisor.

To evaluate the utility of subperiosteal tissue expansion (STE) for mandibular augmentation with hydroxylapatite (HA) particles, two experimental studies in adult mongrel dogs were performed. One was to observe histologic changes following STE and to compare the tissue response to STE with that to subcutaneous expansion. The other was to observe clinical and histologic changes following implantation of HA particles in the subperiosteal expanded bed. In the first experiment, small tissue expanders were placed and inflated subperiosteally in the mandible and subcutaneously in the breast. A fibrous connective tissue capsule was formed surrounding the implanted expanders. Periosteum was replaced by simple connective tissue during expansion. Capsule formation during STE was much more rapid than the subcutaneous expansion. In the subperiosteal group, a thick fibrous capsule consisting of coarse collagen fibers was observed one week after full inflation. Leaving the fully inflated subperiosteal expanders in place more than one month accelerated the resorption of the underlying bone. In the second experiment, one week after full expansion of the mandibular subperiosteal expander, the expander was removed and HA particles were implanted in the expanded bed. Despite marked augmentation with excessive amounts of HA particles, there was no deformity or infection of the grafts, which maintained their designed controur. The firm fibrous capsule formed by STE permitted consolida tion of HA particles easily and effectively, and prevented migration of the particles. Immobilization of the grafts was achieved within two months following implantation of the HA particles.

Six cases with severely atrophic edentulous alveolar ridges, in which subperiosteal tissue expander (STE) was used before ridge augmentation with hydroxyapatite-tricalciumphosphate compound (HA-TCP) particles, were presented. In many cases, full inflation of the STEs could be achieved immediately after insertion thereof. One week after full inflation of the STEs, implantation of HA-TCP particles was performed. At that time, relatively firm subperiosteal envelopes were observed. Since the envelopes prevented migration of the particles, secondary vestibuloplasty due to loss of depth of the vestibule was not necessary except for one case that reguired removal of denture fibrosis. In all cases, functional and stable ridges were formed. As for complications, one patient had unilateral paresthesia of the lower lip and another had perforation and dehiscence.

Primary carcinoma arising in the dorsum of the tongue is very rare and may be erroneously diagnosed as a benign lesion.<BR>We present a case of squamous cell carcinoma of the dorsum of the tongue in a 49-year-old man. Intraoral examination revealed a tumor measuring 41×30×7 mm in the midline of the dorsum of the tongue. A biopsy was performed, and the diagnosis was squamous cell carcinoma. After preoperative chemotherapy, total resection of the tumor was performed. During about 1 year of follow-up, there has been no sign of recurrence or metastasis.

最近5年3カ月間に, 東京医科歯科大学歯学部附属病院第1口腔外科で行なわれた切除手術 (照射群31例, 対照群14例) , および病理解剖 (照射群1例) で得られた成熟下顎骨を対象とし, 口腔癌放射線治療後の放射線骨障害の病態を病理組織学的 (脱灰染色標本, およびmicroradiography) , ならびにX線学的 (摘出物X線写真) に観察した。その結果を要約すると次の通りである。1.歯周組織では歯槽骨の高度な不規則な吸収が認められた。2.骨膜では骨芽細胞, 線維細胞の減少傾向, 線維の硝子化がみられた。3.皮質および骨梁の吸収性変化として, 不規則, 奇妙な形態の吸収, 骨小腔の拡大などが観察された。4.骨細胞の障害の表現として, 空の骨小腔ならびに核を認めえない骨小腔の数の割合を求めた。その結果, 臨床的経過とかなりの対応が得られた一方, 臨床症状を伴わない潜在的な障害も相当程度あるものと考えられた。5.硬化性の変化として, 海綿質骨梁増生, 皮質外表の骨梁増生および緻密骨添加, Havers管, Volkmann管の狭窄ならびに閉塞などが認められた。6.骨髄腔, 下顎管内および吸収腔において, 線維化, 炎症性細胞浸潤, 組織融解がみられた。7.血管系の変化として, 下歯槽動脈, 細動脈に内膜の肥厚, 内腔の閉塞, 弾性線維の配列の乱れ, 崩壊, 融解がみられ, またHavexs管, Volkmann管内血管にも種種の様相の閉塞像が観察された。8.X線写真所見により, I類: 不規則な吸収が主なもの, II類: 硬化性陰影が強いもの, III類: 吸収像, 硬化像が不規則に混在するもの, IV類: 著変ないもの, の4類に分類され, III類が圧倒的に多かった。9.X線写真のX線透過像については, 組織像での皮質, および骨梁における様様の程度の吸収像が, またX線不透過像については, 種種の骨増生, 添加が基本をなしていると考えられた。10.これら下顎骨における変化の程度は, 局所的臨床所見 (特に放射線治療後の) とおおよその関連性が認められた。11.下顎骨のいわゆる放射線骨壊死の成り立ちについて, 文献的考察を加え, 若干の検討を行なった。
