ABSTRACT:OBJECTIVETo study the correlation between anatomic structure of the inferior alveolar nerve canal and dental implantation by measuring mandible innervation esemplarsMETHODSThe intramandibular course of mandibular canal and its dimendion were measured in 15 mandibles with teeth; the relationship between blood vessel and nerve was observed in 5 fresh samples in which the artery was filled; and then the data were analyzed by statisticsRESULTSThe mandibular canal was close to the lingual side and the inferior margin of the mandible, the mandibular canal and the 10mm underside of mandible were parallel in the region of the first and the second molars, it runned outboard to genal aperture when it was hereabout genal aperture, and the blood vessel lay above nerve in the mandibular canalCONCLUSIONIn implant operation performed according to normal anatomy, injury to inferior alveolar nerve may be avoided.

［目的］探讨下颌管的解剖结构与牙种植的关系［方法］选取15具牙列完整的成人离体下颌骨标本和5具经过动脉血管内灌注的新鲜标本，测量下颌骨在每个牙位截面上有关牙槽嵴及下颌管的相关数据，进行统计学分析［结果］牙槽嵴顶以及下方10mm宽度由前向后逐渐增宽；牙槽嵴由上向下逐渐增宽；下颌管位于下颌骨体内下方走行中偏舌侧，并近下颌骨下缘，在下颌第1，2磨牙区下颌管走行与下颌下缘成平行状，在近颏孔处转向外和向颊侧出颏孔；下颌管内血管位于下牙槽神经之上［结论］牙种植术中按正常解剖部位并且侧重颊侧骨板操作，可避免损伤下牙槽神经；如果术中下颌管内突然涌出大量新鲜血液，则提示若继续手术可能损伤下牙槽神经。

Results (1) 6 cases of Tuberous Sclerosis. Diffused subependymal nodular calcification lesions were found in all cases on unenhenced CT. 4 patients are 2 pairs of mother/child relationship. Both of the two mothers are found to suffer from renal angiomyolipoma.(2)1 case of neurofibromatosis showed abnormal spinal canal: scoliosis of thoracic and lumbar spine, concave change of vertebral posterior border. Bilateral renal hypogenesis was found in this patient. Diffused hyper-density lesions were found in kidney and fatty accumulation was found in back skin.(3)6 cases of Sturge-Weber syndrome. On unenhenced CT, curving and strip-shaped calcifications were found along the parietal and occipital gyrus.

结果 ①结节性硬化6例，所有病例CT平扫见两侧脑室室管膜下多发小结节状高密度钙化灶，其中4例为两对母子关系，并见两位母亲合并有肾脏错构瘤，；②神经纤维瘤病1例，MRI表现为椎管异常，胸腰段脊柱侧弯，椎体后缘呈明显的切凹改变；伴有双肾发育不良，CT示肾内多个高密度影，背部皮肤多量脂肪堆积，③脑颜面血管瘤综合征6例， CT可见顶枕部沿脑回分布的弯曲的条状高密度钙化，部分延伸致侧脑室内，增强后见病灶内有扭曲的条状和结节状明显强化的血管影；④小脑血管瘤病4例，影像学表现为小脑内大囊、小结节样占位性病变。

It frequently happened that when M. Madeleine was passing along a street, calm, affectionate, surrounded by the blessings of all, a man of lofty stature, clad in an iron-gray frock-coat, armed with a heavy cane, and wearing a battered hat, turned round abruptly behind him, and followed him with his eyes until he disappeared, with folded arms and a slow shake of the head, and his upper lip raised in company with his lower to his nose, a sort of significant grimace which might be translated by: What is that man, after all?

常常，马德兰先生恬静和蔼地在街上走过，在受到大家赞叹时，就有一个身材高大，穿一件铁灰色礼服，拿条粗棍，戴顶平边帽的人迎面走来，到了他背后，又忽然转回头，用眼睛盯着他，直到望不见为止；这人还交叉着两条胳膊，缓缓地摇着头，用下嘴唇把上嘴唇直送到鼻端，做出一种别有用意的丑态，意思就是说：这个人究竟是什么东西呢？
