颞下窝及颅中窝手术入路应用解剖

目的：为颞下窝和颅中窝入路提供相关的解剖依据。方法：测量４０例颅骨，确定颧弓点至颞下窝、翼点至颅中窝内各结构的距离和夹角。结果：测出了颧弓点至颞下窝８项解剖标志、翼点至颅中窝１１项解剖标志的连线长度和各连线与正中矢状面成角。结论：两种手术入路相关数据的测量。有助于设计手术入路，并可为术中准确定位有关结构提供参考依据。

APPLIED ANATOMY FOR APPROACHES OF THESUBTEMPORAL FOSSA AND MEDIA CRANIAL FOSSA

Objective: To study the related anatomy of surgical approaches to the subtemporal fossa andmedia cranial fossa. Methods: The length of lines linking zygion to the structures in subtemporalfossa, pterion to the structures in media cranial fossa, the angles between these lines and medianvector were measured on the 40 cranium. Results: The distances and angles from zygion to inferi-or orbital fissure, pterygomaxillary fissure, pterion orifice, oval formaen, spinose foramen were37.5±3.7 mm(131.2°±5.4°), 43. 1±4.3 mm(101.2±7. 9°), 51. 3±3. 0 mm(76. 7°±4. 3°),38.2±2.6 mm(74.0°±4.5°) and 36.4±2.7 mm(65.0°±6.3°), respectively. The same itemsmentioned above from pterion to anterior clinoid process, internal canalis optic nerve aperture,round foramen, oval foramen, spinose foramen, interal canalis carotid aperture, trigeminal im-pression, greater superfical petrosal nerve hiatus, superpetrosal sinns groove were 49.0± 3.3 mm(73.2°±5.6°), 47.8±3.3 mm(82.8°±5.2°), 48.9±4.7 mm(76.7°±7.0°), 50.2±4.2 mm(58.2°±7.0°), 50. 1±4.2 mm(48. 6°±7.4°), 55.7±3.8 mm(62.2°±5.0°), 52.0±3.6 mm(51.8±6.4°), 50. 0±3.4 mm(39.9°±7.0°), 53.1±2.8 mm, respectively. Conclusion: This measure-ments well benefit the design of surgical treatment and provide useful references for defining theposition of importent structures in operations.
