Although nearly half of all schwannomas involve the head and neck region, nasal and paranasal sinus presentations are quite rare in the literature. Two of the latter cases are presented in this report. In the first, the tumor originated from the nasal septum and was completely excised under local anesthesia. In the second, the schwannoma arose from the left frontal and anterior ethmoidal sinuses. This lesion was totally removed through a combined endoscopic intranasal and external frontoethmoidectomy approach. The patients have shown no tumor recurrence in 6 years and 18 months of follow-up, respectively. The extreme rarity of nasal and paranasal sinus schwannoma is the basis for discussion of these cases.
尽管几乎一半的神经鞘瘤发生在头颈部区域，但鼻腔和鼻窦部位的表现在文献中相当罕见。本报告展示了后一种情况中的两例。第一例中，肿瘤起源于鼻中隔，在局部麻醉下被完全切除。第二例中，神经鞘瘤起源于左侧额窦和前筛窦。通过鼻内镜联合鼻外额筛窦切除术的方法将该病变完全切除。在分别为期6年和18个月的随访中，这两名患者均未出现肿瘤复发。鼻腔和鼻窦神经鞘瘤极为罕见，这也是讨论这些病例的基础。
