In a series of 74 nasal dermoids, 45 (61%) were of the simple variety involving skin only. Twenty nine (39%) were of the complex variety with deeper tissue involvement requiring more extensive surgery. Of the 29 complex dermoids, 9 (31%) extended to the cribriform plate region but only 3 (10%) of these had an extradural extension. All of the complex nasal dermoids were adequately managed by a transnasal approach. On these findings a preliminary craniotomy should only be considered in exceptional circumstances.
在一组74例鼻皮样囊肿中，45例（61%）为单纯型，仅累及皮肤。29例（39%）为复杂型，累及更深层组织，需要更广泛的手术。在这29例复杂皮样囊肿中，9例（31%）延伸至筛板区域，但其中只有3例（10%）有硬膜外延伸。所有复杂型鼻皮样囊肿均通过经鼻入路得到妥善处理。基于这些发现，仅在特殊情况下才应考虑进行初步开颅手术。
