鼓索神经是面神经的一个重要分支,含有支配舌前2/3味觉的感觉纤维及支配颌下腺、舌下腺的副交感纤维,由于其复杂的解剖径路关系,中耳及乳突手术多易造成损伤。损伤后的并发症虽远不致于危及生命,但可能使得患者极为苦恼,且难以治疗,故应引起临床足够的重视。随着现代耳科学的进展,中耳手术中如何处理鼓索神经问题,已引起耳科手术者的极大关注,现将有关文献综述如下。 Drum nerve is an important branch of the facial nerve that contains the sensory fibers that dictate the taste of the first two thirds of the tongue and the parasympathetic fibers that dominate the submandibular gland and the sublingual gland. Due to its complex anatomical and radial pathology, the middle ear and mastoid tend to cause more damage . Although the complications after injury far from life-threatening, but may make patients extremely distressed and difficult to treat, it should cause clinical enough attention. With the progress of modern otology, how to deal with the problem of chordoma in middle ear surgery has caused great attention of otology surgeons. The related literature is summarized as follows.
