Methods 21 cases of craniopharyngoima in suprasellar region were resected by trans-supraorbital approach, the diameter of tumors varied from 3.0 to 6.5cm; partial cystic tumor in 13 and solid tumor in 8. Skin incision was made in eyebrow, the hemicycle bone flap was approximately 2.5cm×3.0cm, tumor was dissected in I,II,III spaces and trans-endplate.

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。
