Cerebrospinal fluid (CSF) leaks may occur after acoustic neuroma resection. These leaks are usually the result of an iatrogenic injury during removal. The retrosigmoid approach is commonly associated with leaks that occur through the lateral end of the internal auditory canal, through the perilabyrinthine cells extending to the region of the internal auditory canal, or through the retrosigmoid air cells. We describe a case of an infracochlear CSF leak that developed following the retrosigmoid resection of an acoustic neuroma. To the best of our knowledge, this leak was unique for both its location and etiology.
听神经瘤切除术后可能会发生脑脊液（CSF）漏。这些漏通常是切除过程中医源性损伤的结果。乙状窦后入路通常与通过内耳道外侧端、通过延伸至内耳道区域的迷路周围细胞或通过乙状窦后气房发生的漏有关。我们描述了一例听神经瘤乙状窦后切除术后发生的蜗下脑脊液漏病例。据我们所知，这种漏在位置和病因方面都是独特的。
