国人下颌孔的定位研究

Study of the position of the mandibular foramen of the Chinese

中国人颏孔与下颌孔的研究

A study of mental and mandibular foramina of Chinese adults

对500个成人下颔骨的颏孔和下颌孔进行了研究。

The mental and mandibular foramina of 500 adult Chinese mandibles were studied .

结果下颌孔最下点到升支后缘的平均距离男性为16.12mm，女性为16.03mm；

Results The average distance of the inferior point of foramen to posterior margin of ramus is 16.12 mm in males and 16.03 mm in females .

人的嘴、下巴和颏的部位在基准位置下，颏孔及下颌孔部的变形失真率最大。

The area of the human mouth , chin , and jaw . The largest distortion was at mental and mandible foramen regions at standard positon .

方法选用正常成人颅骨标本50个，用游标卡尺、探针等工具观测上颌结节、腭大孔、切牙孔、眶下孔、下颌孔的位置及其对应关系。

Methods Using vernier caliper and probe to observe the anesthesia positions of the maxillae tuber , palatinum foramen , incisivum foramen , infra-orbitale foramen and mandibulae foramen and their correlations .

下颌骨外侧面下颌副孔的研究

Study of the Accessory Foramina in the Lateral Mandibular Surface

冠区下颌副孔出现率为23.17%；

Only 23 . 17 % of mandibles showed foramen in the coronoid ;

最后，讨论了下颌无名孔在下颌血液供应、神经支配方面的重要意义。

Final , significance of unnamed foramina in mandible for blood supply and nerve innervation were discussed .

结果各标本之间下颌副孔数差异很大。

Results It was found that the number of accessory foramina varied greatly from specimen to specimen .

方法对82例下颌骨外侧面下颌副孔进行研究并统计分析。

Methods The accessory foramina of 82 mandible on the lateral surface were studied and statistically analysed .

结论下颌副孔为肿瘤细胞播散到下颌骨提供有效途径。

Conclusion The foramen could provide efficient route for tumour cells spread to the medulla of the mandible .

目的研究下颌副孔的位置，探讨肿瘤细胞向下颌骨播散的可能途径。

Objective To study the location of the accessory foramina of the mandible and assess the possible route of spread of the tumour cell to the mandible .

结果：灌胃15d后，立体显微镜下可见，模型组大鼠下颌角下缘和下颌孔上缘有骨膜下骨吸收区存在；

RESULTS : After 15 day of the administration of retinoic acid , bone resorption regions in subperiosteum were seen in the lower border of mandibular angle and the upper border of mandibular foramen in the rats of model group under anatomic microscope .

解剖显微镜下可见，大鼠下颌角下缘和下颌孔上缘有骨膜下骨吸收区存在；

The bone resorption regions in subperiosteum was seen in the lower border of mandibular angle and the upper border of mandibular foramen by anatomic microscope .

下颌支外侧隆凸与下颌孔的关系

The Relationship Between the Lateral Prominence of the Mandibular Ramus and the Mandibular Foramen

发现翼颌间隙的空间大小和下牙槽神经、下颌舌骨神经、舌神经的毗邻关系以及下颌孔的位置都有明显的变动范围。

It was found that the size of the pterygomandibular space , the relation between the adjacent positions of the inferior alveolar , the mylohyoid , and the lingual nerves , and the site of the mandibular foramen were obviously changeable to some extent .

结果下颌升支后缘前方15mm范围内由后向前逐渐增厚，部分下颌升支在下颌孔上方10mm处无松质骨。

Results Thickness became gradually greater within 15 mm from the back edge of ramus . Some adult mandibular rumi had no spongy bone at the level of 10 mm above mandibular foramen .
