    The purpose of this study was to clarify the relationship between shapes of the epiglottis and risk of aspiration. The subjects consisted of ten normal volunteers and sixty-eight stroke patients with dysphagia. Using videofluorographic images, shapes of the epiglottis were divided into three groups, straight, curved, and closed type. The appearance ratio of types of epiglottis shape in normal volunteers was not significantly different from those in dysphasic patients. The risk of aspiration was significantly different from the types of epiglottis shape, which was the highest in the patients of curved epiglottis and lowest in those of straight-type epiglottis.
    The results revealed that the shape of the epiglottis is useful to predict the risk of aspiration.

    下顎枝矢状分割術後の骨片の分割, 固定状態と骨性治癒との関連を明らかにすることを目的に行った。
    対象は, 当科において下顎枝矢状分割術を施行した下顎前突症例の12例, 24側を対象とし, 術直後と術後1年の3次元CT像により観察した。
    結果は, 1年後の下顎枝前縁・後縁の形態は, 平滑型 (近遠位骨片辺縁が識別不能で滑らかに移行しているもの) は下断面で多く認められた (70.8%) が, 上断面では, 平滑型は少なく (39.6%), 階段型 (近位および遠位骨片のどちらかが突出し階段状となったもの) が多く (43.8%) 認められた。また, 陥凹型 (骨片間に間隙がみられ陥凹した形態のもの) は上下断面ともに前縁に多く認められた。
    下顎枝後縁形態と近遠位骨片の分割状態との関係では, 下断面においては, 下顎枝後縁まで分割されると階段型が, 後縁よりも近位で分割されると平滑型が多い結果であった。
    下顎枝前縁・後縁形態と骨片間距離との関係では, 陥凹型, 階段型, 平滑型の順で骨片間距離が大きかった。また, 陥凹型は骨片間距離の平均が6.1mm以上の症例において認められた。
    遠位骨片の後方突出量と下顎枝後縁形態との関係については, 上断面では後方突出量は階段型, 平滑型, 陥凹型の順で大きく, 下断面では, 階段型, 陥凹型, 平滑型の順で大きくなっていた。また上下断面ともに, 階段型は後方突出量が5.3mm以上の症例で認められた。
    以上の結果より, 骨片の間隙が大きい場合や分割面が下顎枝後縁まで分割され後縁突出量が大きくなる場合には, 術後1年経過しても解剖学的形態でないものが認められた。

    This study was to done to evaluate auditory psychological factors concerning assessment of dysphagia using cervical auscultation. A semantic differential technique was used to obtain the auditory psychological factors in this study. Expiratory sounds after swallows were recorded from 17 head and neck cancer patients, and they were classified in five categories according to videof luorograf is findings.
    Thirteen clinicians and nine acoustic scientists judged each of 23 sound samples, and scored them using a seven-step scale.
    The results of factor analyses of auditory psychological experiments were similar in both the clinician and engineer groups. Three factors were extracted, and each factor had high factor loading in similar semantic scales.

    Aneurysmal bone cysts in the maxilla and mandible are extremely rare. We reported a case of aneurysmal bone cyst in the mandible treated successfully with an embolization. The patient was a 16-year-old woman. The chief complaint was swelling in the right buccal region. Preoperative at the first surgery with biopsy, the thinned cortical bone and bleeding from the bone marrow were observed. Bone resorption was observed, but tumorous tissue could not be seen. The inner layer of the bone was curetted. Based on the biopsy and the clinical findings, this lesion was diagnosed as aneurysmal bone cyst. During follow-up arterial embolization and sclerotherapy were added. The buccal swelling was diminished, and no evidence of recurrence was observed.

    A case of central odontogenic fibroma with the impacted deciduous second molar in a 3-year-old boy is presented. Panoramic radiograph demonstrated a monolocular radiolucent lesion over the crown of the deciduous second molar. Under clinical diagnosis of a dentigerous cyst or benign tumor, the lesion was extirpated, and the crown was exposed to the oral cavity by marsupialization. The removed specimen was histologically diagnosed as odontogenic fibroma. The impacted deciduous second molar erupted completely in normal position 1 year after marsupialization. A tooth germ of the permanent second premolar was observed on the panoramic radiograph 3 years and 5 months after surgery, and there was no evidence of the tumor recurrence after 4 years.

    Electrotome is frequently used for surgical treatments in the field of dentistry and oral surgery. We report a rare case of gingival and alveolar bone necrosis caused after gingivectomy with electrotome. The patient was a 30-year-old female complained of gingival discolor. She noticed the gingival discoloration 2 days after the gingivectomy with electrotome by her family dentist. The gingiva around the left upper central incisor was changed to white in color. Nine days after the electrosurgery, the left upper central incisor fell off spontaneously, and 7 weeks after the electrosurgery, the sequester was removed. Epithelization was completed 2 weeks after the sequestrectomy, and she was successufully treated by the fixed bridge and removable artificial gingiva.
