摘　　要：目的分析前颅窝底神经上皮囊肿病例的诊治,探讨无导航鼻内镜手术切除前颅窝良性病变的可行性,术前影像学处理及手术技巧。方法右前颅窝囊性病变患者行鼻内镜下颅底囊肿切除加一期原位修复术,术中证实为囊肿,完整切除。术中用软件Osiri X即时观察影像学资料。结果术后患者头痛消失,痊愈出院,无并发症;病理检查结果为神经上皮囊肿。结论鼻内镜下前颅窝底囊肿切除是一种安全、微创、有效的术式,恰当的影像学后处理有助于手术风险和疗效评估。Objective To report the diagnosis and treatment of neuroepithelial cyst of anterior cranial fossa,and to study the feasibility,techniques and preoperative imaging postprocessing of intranasal endoscopic surgery for benign lesions of anterior cranial fossa without a navigation system. Methods A 46-year-old female had a 3-year history of headache. Her CT and MRI images with post-processing revealed a cystic lesion of frontal lobe,located in the anterior cranial fossa. The cyst was removed completely via intranasal endoscopic approach. Then,the resulting defect was reconstructed in situ immediately. During the operation,CT and MRI images were analyzed again at the same time. Results Surgery confirmed that the lesion was cyst and removed completely. After operation,the patient was cured with no longer headache and discharged from hospital without any complication. Pathological examination showed the lesion was a neuroepithelial cyst.Conclusions Intranasal endoscopic approach is safe,minimally invasive,effective for resecting cyst of anterior cranial fossa base. Proper image postprocessing contributes to assessment of surgical risk and effect.
