目的：探讨岬沟及岬骨管在鼓室神经切除术中的意义。方法：利用显微解剖学技术对１００个成人颅骨的２００侧鼓室进行观察。结果：大部分标本均存在岬沟，以１条者多见，占８９．０％，２条者１１．０％。岬骨管可分为隆凸型及隐型两类，以岬下部多见，岬表可有岬窦存在。鼓室小管上口可位于岬下缘圆窗后下鼓室内的任何部位，下口多位于岩下窝，也可位于颈静脉窝及颈动脉管内。结论：岬沟及岬鼓管等结构可作为鼓室神经切除时寻找鼓室神经的标志。
Objective: To investigate the significance of cape and cape canal in tympanic hysterectomy. Methods: Microsurgical anatomy was used to observe the tympanic cavity of 200 sides of 100 adult skulls. Results: Most of the samples were present in the cape, more common in 1, accounting for 89.0%, 2 of 11.0%. Scallop tube can be divided into two types of protuberance and invisibility, more common in the lower part of the promontory, promontory may have cape. Tympanic canal upper mouth can be located at the lower edge of the promontory under the window drum any part of the lower chamber, the lower mouth and more located in the petrous nest, can also be located in the jugular fossa and carotid artery. Conclusion: The structures such as cape head and cambrian can be used as a marker to find tympanic nerve in tympanic nerve resection.
