We present a case of giant olfactory neuroblastoma with special reference to a new operative approach in cases of dumbbell-shaped tumor in the anterior cranial fossa. Our new approach is characterized as follows: resection of the bilateral orbital roof and frontal sinus en bloc, following bifrontal conventional craniotomy. Accordingly, retraction of the frontal lobe is minimized and it is possible to obtain, with ease, a good operative field extending to the region adjacent to the tuberculum sellae. Using this technique combined with the transsphenoidal approach, even in the case of marked extracranial downward extension of a dumbbell-shaped tumor, it should be possible to remove the tumor totally. This approach should open a way to a wide range of application.
我们报告一例巨大嗅神经母细胞瘤，并特别提及前颅窝哑铃形肿瘤的一种新手术方法。我们的新方法具有以下特点：在双侧额部常规开颅术后，整块切除双侧眶顶和额窦。因此，额叶的牵拉最小化，并且能够轻松获得延伸至鞍结节附近区域的良好术野。使用该技术结合经蝶窦入路，即使在哑铃形肿瘤明显向颅外向下延伸的情况下，也应该能够完全切除肿瘤。这种方法应为广泛应用开辟一条道路。
