既往有关面神经周围存在脂肪的报道甚少,该作者观察240例颞骨标本,对乳突部面神经的脂肪组织来源及影像学定位进行阐述。每个哺乳动物都有丰富的脂肪组织,本组240个颞骨标本,乳突部面神经周围含有脂肪组织的占17％。Neely复习25个婴幼儿的颞骨标本,发现在面神经骨管的中后部有裂隙,周围组织通过这个裂隙与面神经鞘粘连,推测脂肪组织是在面神经和乳突发育过程中进入的,在乳突的发育早期存在脂肪细胞,一些脂肪细胞可能留在了发育成熟的乳突腔中。本文报告一例,16岁女孩,在进行听力学检查
In the past, there were few reports about the presence of fat around the facial nerve. The author observed 240 cases of temporal bone specimens and explained the origin and imaging location of the adipose tissue in the facial papilla. Each mammal is rich in adipose tissue, the group of 240 temporal bone specimens, papillae facial nerve contains 17% of fat tissue. Neely review of 25 infantile temporal bone specimens and found in the facial nerve in the posterior cranial fissure, the surrounding tissue through the fissure and facial nerve sheath adhesion, presumably in the development of facial nerve and mastoid fat during the milk, milk Adipocytes are present in the early stages of development and some adipocytes may remain in the mature mastoid cavity. This article reports an example of a 16-year-old girl undergoing an audiological examination
