目的:探讨儿童上颌窦异位脑膜瘤的临床表现及诊治方法。方法:对4例儿童上颌窦异位脑膜瘤的临床资料进行回顾性分析并复习文献。结果:4例患儿表现为进行性鼻塞,其中1例伴有眼球突出,临床检查4例于鼻腔外侧壁可见类球状新生物,黏膜光滑,质硬。CT检查显示,上颌窦鼻腔新生物高密度影,边界清楚,周围可见骨质吸收。治疗均于全身麻醉下手术切除,3例采用面中翻揭术,1例采用鼻侧切开术,随访4～6年无复发。结论:CT对上颌窦异位脑膜瘤的诊断有重要意义,完整切除肿瘤是治疗儿童上颌窦异位脑膜瘤的最佳方法。
Objective: To investigate the clinical manifestations and diagnosis and treatment of ectopic meningiomas in children with maxillary sinus. Methods: The clinical data of 4 cases of children with ectopic meningioma of the maxillary sinus were retrospectively reviewed and reviewed. Results: Four cases showed progressive nasal obstruction. One case was accompanied with prominent of the eyeballs. Four cases were found in the outer wall of the nasal cavity. The globular neoplasms showed a smooth and hard mucosa. CT examination showed that the nasal cavity of the maxillary sinus had a high density of neoplasms with a clear boundary and bone absorption around it. All patients underwent surgical resection under general anesthesia. Three patients underwent facet dissection and one patient underwent nasal incision. No recurrence was observed after 4 to 6 years of follow-up. Conclusion: CT is of great significance in the diagnosis of ectopic meningioma of the maxillary sinus. Complete resection of the tumor is the best method for the treatment of ectopic meningioma in children.
