摘要
在１００个成年颅骨和２４侧尸头上对舌咽神经及鼓室神经切除术的应用解剖进行了研究，提出了乳突、鼓板下缘、茎突等骨性标志可作为手术入路的导向。鼓板下缘距鼓室底的距离为９．４±１．９ｍｍ，最小值为５．３ｍｍ。舌咽神经干在颈动脉鞘的前内侧易与颈动脉鞘分离。舌咽神经在近颈静脉孔处膨大形成下神经节，鼓室神经自下神经节的外侧发起者占４２．８％，后方发起者为４２．９％，前方发起者１４．３％。本文还对手术入路和手术技术问题进行了讨论。
Glossopharyngeal nerve and tympanic nerve was studied on 100 adult skulls and 24 sides of cadaveric head specimens.Some landmarks,such as mastoid process,the inferior border of tympanic plate and styloid proces,could be helpful to decide the operative apporach.The average distance and the shortest distance between the inferior border of tympanic plate and the tympanic cavity were 9.4±1.9 mm and 5.3 mm respectively.The glossopharyngeal nerve can be easily separated from the carotid sheath at the anterolateral surface.The inferior ganglion is formed near the jugular foramen by glossopharyngeal nerve.The tympanic nerve leaves it from either the lateral(42.8%) or the posterior (42.9%) or the anterior(14.3%) side.The operative approach and technique are discussed.
