Abstract：
The exhaustive information regarding the types of trigeminal pore (TP) or trigeminal impression (TI), internal acoustic opening (IAO), and related surgical approaches is lacking in the literature. Therefore, this study is performed to further elucidate the types of TP or TI, IAO, and the relationships with critical surgical landmarks in the skull base.
Trigeminal impression (TI) and internal acoustic opening (IAO) found in 11 dry skulls, 24 right temporal bones, and 25 left temporal bones were examined on both sides to define their relationship to each other and nearby structures. The age and sex of these bones were not identified. Besides these, 77 skulls were examined by radiologic imaging methods. These skulls were identified by gender.
According to test results, there was a significant difference between the left and right internal acoustic opening in the case of horizontal dimension (HD). The left HD-IAO is bigger than the right one. In addition, right HD-IAO, vertical dimension (VD) of right internal acoustic opening, left HD-IAO, and left VD-IAO values differed significantly in male and female patients.
Investigating the relationship of TI and IAO with relevant structures suggests that surgical approaches involving the TP and IAO indicated that surgical approaches considering the TI and IAO variations may be used in the development of surgical processes and primary surgical interventions.

摘要：
目的：关于三叉神经孔（TP）或三叉神经印模（TI）类型的详尽信息，内部声学开口（IAO），文献中缺乏相关的手术方法。因此,进行这项研究是为了进一步阐明TP或TI的类型，IAO,以及与颅底关键手术标志的关系。
方法：在11个干头骨中发现了TI和IAO，24个右颞骨，在两侧检查了25块左颞骨，以确定它们与彼此和附近结构的关系。这些骨头的年龄和性别尚未确定。除了这些,通过放射学成像方法检查了77个头骨。这些头骨是按性别识别的。
结果：根据测试结果，在水平尺寸（HD）的情况下，左右内部声学开口之间存在显着差异。左边的HD-IAO比右边的大。此外,右HD-IAO,右侧内部声学开口的垂直尺寸(VD)，左HD-IAO,离开了VD-IAO,男性和女性患者的值有显著差异。
结论：研究TI和IAO与相关结构的关系表明，涉及TP和IAO的手术入路表明，考虑到TI和IAO变化的手术入路可用于手术过程和主要手术干预的发展。
