Aural cholesteatoma is a disease entity well known to the otologic community. Complications of cholesteatoma, although uncommon, are not usually life threatening. We present two cases in which a unique and hitherto unreported pathway of spread of a cholesteatoma is noted. The cholesteatoma, after originating in the ear, entered the diploë and spread insidiously between the inner and outer tables to distal parts of the skull. Osteomyelitis, in concert with the cholesteatoma, destroyed large areas of the skull in both patients. One patient died of his disease. The other patient was operated on and is alive but has unresectable disease and purulent drainage from three separate cranial fistulas.
耳胆脂瘤是耳科学界熟知的一种疾病实体。胆脂瘤的并发症虽然不常见，但通常不会危及生命。我们报告两例病例，其中观察到一种独特的、迄今未被报道的胆脂瘤扩散途径。胆脂瘤起源于耳部后，进入板障，并在内板和外板之间悄然扩散至颅骨远端。骨髓炎与胆脂瘤共同作用，破坏了两名患者的大片颅骨。一名患者因病死亡。另一名患者接受了手术，目前尚存活，但患有无法切除的疾病，并有三处独立的颅骨瘘管出现脓性引流。
