Cholesteatoma may arise because of a number of events, but serous otitis media appears to be the precursor in the majority of instances. Whether one enters into conservative, simple excision of the keratotic mass or a more extensive modified radical mastoidectomy or radical exteriorizing procedure will depend upon whether the cholesteatoma is in a very small "pearl-like" mass, confined to a limited area, or whether it is dispersed to the point where total eradication is all but impossible.
胆脂瘤可能由多种情况引起，但在大多数情况下，浆液性中耳炎似乎是其先兆。采取保守治疗、简单切除角化肿块，还是更广泛的改良乳突根治术或根治性外置手术，将取决于胆脂瘤是呈非常小的“珍珠样”肿块且局限于有限区域，还是已扩散到几乎无法彻底根除的程度。
