摘　　要：目的　为鼓室神经切除术提供颈鼓神经的解剖学资料。方法　在手术显微镜下对 15 1例尸头及 10 0块颞骨颈鼓小管上、下口的位置、颈鼓神经的交通情况进行了观察。结果　颈鼓小管下口多起自颈动脉管升部后壁 ,上口多位于鼓室隐窝前壁及鼓室内的咽鼓管口处。颈鼓神经与咽鼓管下支交通者占 6 5 5 6 % ,与鼓室神经干相交通者占 2 9 14 %。结论　与鼓室神经相交通的颈鼓神经有可能被误认为鼓室神经双干的前干 。Objective To provide anatomical data of cervical tympanic nerves for the resection of tympanic nerves. Methods By operative microscope,the locations of superior and inferior opening of cervical tympanic canals as well as the communication of cervical tympanic nerves were observed on 151 sides of cadaveric heads and 100 temporal bones. Results The inferior openings of cervical tympanic canals come commonly from the posterior wall of the ascent segment of carotid canals. The superior opening located mainly in the anterior wall of tympanic recess and the outside of pharyngeal opening of anditory tube. The cervical tympanic nerves communicated with the inferior of pharyngotympanic tube nerves(65 56%),with the trunk of tympanic nerves(29 14%). Conclusion The cervical tympanic nerves which communicates with tympanic nerves could be mistaken for the anterior branch of the doubled tympanic nerves and should be cut off when resect the tympanic nerves.
