Cholesteatomas of the frontoethmoid region must always be considered in the differential diagnosis of a mass in the frontoethmoid region. A painless, slow-growing mass, often accompanied by proptosis and diplopia, but without history of trauma or infection, should make one suspect of this pathologic entity. Although histologically a benign lesion, the keratinizing squamous epithelial lining will continue to desquamate and expand, leading to erosion of surrounding structures which could be life-threatening. In order to prevent recurrence, complete removal of the cyst lining is mandatory. Cosmetic reconstruction, often requiring obliteration of the surgical cavity, should be delayed for one year to insure against recurrence of the covering of active squamous tissue adjacent to dura, cribriform plate or ocular structures.
额筛窦区域的胆脂瘤在额筛窦区域肿物的鉴别诊断中必须始终予以考虑。一个无痛、生长缓慢的肿物，常伴有眼球突出和复视，但无外伤或感染史，应使人怀疑这种病理实体。尽管在组织学上是良性病变，但角化鳞状上皮衬里会持续脱屑并扩张，导致周围结构受到侵蚀，这可能危及生命。为防止复发，必须彻底切除囊肿衬里。通常需要闭塞手术腔的美容重建应推迟一年，以确保防止临近硬脑膜、筛板或眼部结构的活跃鳞状组织覆盖物复发。
