由于耳神经外科学及诊断学的发展，人们在实践中逐步认识到颞骨存在一些重要的解剖变异，特别是高分辩CT及MRI技术的应用使得颈静脉球（JB）变异在耳神经外科学和放射影像学研究中引人注目。本文对JB变异的解剖特点、变异类型及临床意义，尤其是与中耳、内耳疾病的关系作一综述 Due to the development of otolog neurosurgery and diagnostics, people have gradually realized in practice that there are some important anatomical variations in the temporal bone. In particular, the application of high-resolution CT and MRI techniques makes the jugular bulb (JB) variation in the ear neurosurgery and Radiographic research attracts attention. In this paper, anatomical characteristics of JB mutation, variation types and clinical significance, especially with the middle ear, inner ear disease are reviewed
