项目摘要

The research results obtained this year are as follows:1. CT images of 47 modern female skulls were taken for comparison with male skulls which were already taken by previous studies.2. CT images of 4 male skulls and 2 female skulls of Jomon period were taken. These skulls were not in good condition, but including maxillary sinus.3. CT images of 6 male skulls and 4 female skulls of Kofun period were taken. These skulls were in good Condition with the maxillary sinus.4. Skulls of Kamakura period were also examined in CT scanning. They were 2 male and 2 female skulls, respectively.5. Skulls of Muromachi period were well preserved in good condition. They were 21 males and 10 female skulls.6. CT images and the results of metric analysis obtained from above mentioned procedure were presented in the intermediate meeting of Frontier Project conducted by Nihon University School of Dentistry at Matsudo, February, 28, 2004.7. Paleopathological approach for maxillary sinusitis in Kamakura period was also undertaken with the use of skulls preserved in St. Mariannn Medical University.8. Volume of the maxillary sinus in Japanese were larger in modern period, but it was not significant. As for cranial measurement, maximum length and zygomatic arch width in Muromachi period were larger than modern Japanese. Because skulls of Jomon period were damaged and small in number, it is necessary to collect more CT images and metrical data from well preserved specimensin the future.

本年度取得的研究成果如下：1。本文采集了47个现代女性颅骨的CT图像，并与已有研究的男性颅骨进行了对比。对绳纹时期4个男性颅骨和2个女性颅骨进行了CT扫描。这些头骨保存状况不佳，但包括上颌窦。采集了古坟时期6个男性颅骨和4个女性颅骨的CT图像。这些头骨与上颌窦保存完好。镰仓时期的颅骨也进行了CT扫描。他们分别是2个男性头骨和2个女性头骨。室町时代的头骨保存完好。其中男性21例，女性10例。上述程序获得的CT图像和度量分析结果发表于2004年2月28日由日本大学牙科学院主持的Frontier Project中期会议。使用圣玛丽安医科大学保存的颅骨，对镰仓时期上颌鼻窦炎进行了古病理学入路治疗。现代日本人上颌窦体积较大，但差异不显著。在颅骨测量上，室町时代的最大长度和颧弓宽度均大于现代日本人。绳纹时代的头骨由于损伤严重，数量少，今后有必要从保存完好的标本中收集更多的CT图像和测量数据。
