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。
Applied anatomy of glossopharyngeal nerve and tympanotomy in 100 adult skulls and 24 cadaveric cadaver heads was studied. The bony signs such as mastoid process, inferior margin of the plate, and styloid process were proposed to guide the surgical approaches . The distance between the lower edge of drum plate and the bottom of tympanum is 9.4 ± 1.9mm with the minimum value of 5.3mm. The glossopharyngeal trunk is easily separated from the carotid sheath in the medial front of the carotid sheath. The glossopharyngeal nerve expands to form the inferior ganglion in the near jugular foramen. The tympanic nerve starts from the outside of the inferior ganglion, accounting for 42.8%, the posterior promoter is 42.9% and the anterior promoter is 14.3%. This article also discusses the surgical approach and surgical techniques.
