目的:到目前为止,尚未研究刺孔(PAI)对种族和人群之间差异的影响。因此,我们进行这项研究是为了进一步阐明PAI的不同形态与种族之间的关系,并讨论它们对手术的影响。
方法:一百二十块干燥的成人颞骨(61名男性,59名女性)在研究中进行了调查。它们的水平直径(HD),垂直直径(VD),形状,PAI形状的普遍性,与乙状窦(SSS)沟的距离,岩窦上沟(SSPS),并记录了干燥的土耳其颞骨的颈静脉孔(JF)。
结果:在土耳其干燥的颞骨中检测到43(35.8%)椭圆形(或横向)和77(64.1%)椭圆形(或圆形)PAI。在两边,圆形PAI的识别频率高于椭圆形PAI(32;26.6%(左);39;32.5%(右))(p<0.05)。从PAI到SSPS(7-8mm)和SSS(19-20mm)的距离(p=0.01)和PAI形态的患病率(卵形和椭圆形)(p=0.04,p<0.05)。
结论:本研究的发现提供了术前和术中识别不同形态PAI和种族的详细理解。种族可能有助于PAI的形态,并且可以解释各种种族之间的相似形式和距离。
OBJECTIVE: The influences of porus acusticus internus (PAI) on ethnicity and differences between populations have not been investigated so far. Therefore, we performed this study to elucidate further the relationship between the different morphologies of PAI and ethnicity and to discuss their effects on surgery.
METHODS: One hundred twenty dry adult human temporal bones (61 male, 59 female) were investigated in the study. Their horizontal diameter (HD), vertical diameter (VD), shape, prevalence of the shapes of PAI, and the distance from the sulcus for the sigmoid sinus (SSS), sulcus for superior petrosal sinus (SSPS), and jugular foramen (JF) of dry Turkish temporal bones were recorded.
RESULTS: Forty-three (35.8%) elliptical (or transverse) and 77 (64.1%) oval (or round) PAI were detected in the Turkish dry temporal bones. On both sides, round PAI were identified more frequently than elliptical ones (32; 26.6% (left); 39; 32.5% (right)) (p < 0.05). There was a similarity between the Indian and Turkish dry temporal bones in terms of distance from the PAI to the SSPS (7-8 mm) and SSS (19-20 mm) (p = 0.01) and prevalence of morphology of PAI (oval and elliptical) (p = 0.04, p < 0.05).
CONCLUSIONS: The findings of the present study provided a detailed understanding of the preoperative and intraoperative identification of different morphologies of PAI and ethnicity. The ethnicity might contribute to morphology of the PAI and it can be explain the similar forms and distances between the various ethnic populations.
