目的:頂孔(parieta1foramen)是唯一位於顱頂，作為導 孔靜脈穿通之孔，通常位於顱頂後半，矢狀緣之旁，本研究是對南台灣成人頭骨的頂孔做一調查，且作進一步探討。
方法:在高雄醫學大學解剖學科所收藏的頭骨中，挑出無病理變化的正常頭骨126個，觀察有無頂孔，頂孔有穿通頭蓋骨之內板(innertable)與否，並以0.35、0.7 、l.0、l.35mm直徑之鐵線可穿通否，而定五種孔徑範圍。結果:觀察結果，雙側出現率約為39.7%(50/126) ;單側出現率約為42.8%(54/126) ，左單側出現率約為19.0%(24/126)，右單側出現率約為23.8%(30/126)。
結論:我們發現頂孔在台灣成人頭骨出現率約為92.1%，而側邊出現率約為82.5%'比率很高。有些學者發現經由頂孔產生腦膜突出症，動靜脈庫管，且擴大的頂孔容易成一些症候群或疾病。

Objective: The aim of our study in discussing the parietal foramen location in Taiwanese adult. Materials & Methods: The number and location of the parietal foramen were examined in 126 adult
Taiwanese skull. We observed its presence or absence， the bilateral symmetry， the lateral differences， the exstenceof a sutural median or multiple foramina ，andthe perforation of one or both table.
Results: Parietal foramen was present in 154 sides (80 right， 741eft) out of252 sides of the skullcap observed， the incidence being 42.8% (23.8% right side， 19.0% left side) of all the sides observed. Incidence of bilateral and unilateral parietal foramen was 39.7% (50 out of 126 skullcaps) and 42.8% (54 out of 126 skullcaps) respectively.
Conclusion: The parietal foramen was more frequent in the right side than in the left side， but the difference was statistically not significant.
