Osteomata of the paranasal frontal and ethmoidal sinuses are benign, slow growing tumors generally asymptomatic. Complications due to orbital or intracranial development of the osteoma are rare and demand neurosurgical treatment. The authors report two cases. In the first a fronto-ethmoidal osteoma first caused exophtalmos and later ophtalmoplegia due to compression of the superior ophtalmic vein. In the second case the posterior development of an osteoma of the frontal sinus resulted in pneumocephalus with epileptic fits and headache and initially homolateral hemiparesis. In both cases CT Scan showed the extent of the osteoma and in the second case the gap in the wall of the sinus. Both osteomata were radically removed through frontal craniectomy. The literature is reviewed, 12 other cases of pneumocephalus due to posterior development of paranasal osteomata have been published during the last 50 years.
鼻窦额窦和筛窦骨瘤是良性、生长缓慢的肿瘤，通常无症状。骨瘤向眼眶或颅内发展引起的并发症罕见，需要神经外科治疗。作者报告了两例病例。第一例，额筛骨瘤最初因压迫眼上静脉导致眼球突出，后来出现眼球运动麻痹。第二例，额窦骨瘤向后发展导致气颅，伴有癫痫发作和头痛，最初还有同侧偏瘫。两例病例的CT扫描均显示了骨瘤的范围，第二例还显示了鼻窦壁的缺损。两例骨瘤均通过额骨切除术彻底切除。本文对文献进行了综述，在过去50年中还发表了另外12例因鼻窦骨瘤向后发展导致气颅的病例。
