Abstract

Background: Hypoglossal canal is a permanent component of skull of human and animal. Situated anterior to occipital condyles, transmits hypoglossal nerve and meningeal branch of ascending pharyngeal artery and emissary vein. Aim: To find the incidence of double hypoglossal canal in crania of South Indian population and its clinical importance. Materials and methods:84 macerated dry skulls of unknown age and sex were collected from Department of Anatomy, ESIC Medical College Gulbarga and from Sharavathi Dental College Shivamogga Karnataka, India. Each skull was observed for doubling of hypoglossal canal. Results: Out of 84 skulls, 29 skulls showed doubling of hypoglossal canal. Among them 10 showed bilateral duplication and 19 unilateral (10 on right and 9 on left side). Incidence calculated as 34.5%. Conclusion: Double hypoglossal canal is important clinically, it may trap the hypoglossal nerve during ossification of occipital bone and useful for surgeons and radiologists and anthropologists. Key words: Double hypoglossal canal, emissary vein, hypoglossal nerve, neoplasms, occipital bone

双舌下管:南印度人群颅骨的研究及其临床意义

背景:舌下管是人类和动物颅骨的永久组成部分。位于枕髁前，传递舌下神经和咽升动脉及使团静脉的脑膜支。目的:了解南印度人群颅内双舌下管的发生率及其临床意义。材料和方法:84个年龄和性别不详的经浸湿的干颅骨分别来自印度古尔巴加ESIC医学院解剖系和印度卡纳塔克邦Shivamogga的Sharavathi牙科学院。观察每个颅骨有无舌下管重叠。结果:84例颅骨中29例出现舌下管加倍。其中双侧重复10例，单侧重复19例(右侧10例，左侧9例)。发病率计算为34.5%。结论:双舌下管在临床上具有重要的应用价值，在枕骨骨化过程中，双舌下管可能夹持舌下神经，对外科医生、放射科医生和人类学家有一定的参考价值。关键词:双舌下管，特使静脉，舌下神经，肿瘤，枕骨
