PURPOSE To retrospectively analyse surgical management of clinico-radiologically proven nasal meningoencephalocele amongst children and results of repair with single-layer septo-mucosal flap at a tertiary skull base surgery centre in north India. METHODS Fifteen children with clinic-radiological nasal meningoencephaloceles with or without CSF rhinorrhoea were included. Radiological scans included CT scans and MRI scans for all cases to delineate soft tissue and bony architecture. All children underwent endoscopic excision of encephaloceles and repair of the skull base defect. RESULTS The authors were successful in fourteen cases. Successful cases included 4 children less than 6 months of age who underwent single-layer rotated septo-mucosal flaps, thereby avoiding donor site morbidity. CONCLUSION As endoscopic excision of nasal encephalocele is an established management approach, the authors take the concept of minimally invasive surgery a step further by successfully managing these lesions with single-layer repair. Vascularized septo-mucosal flap seems to be the only determining factor for a successful repair for congenital meningoencephalocele. However, a prospective study comprising a larger subset of patients would substantiate the assumption.

先天性鼻脑膜脑膨出的内镜处理：一小部分15例儿童病例。

目的回顾性分析印度北部三级颅骨基底手术中心儿童经临床放射学证实的鼻脑膜脑膨出的手术治疗以及单层隔膜黏膜瓣修复的结果。方法包括15例临床或影像学检查的鼻脑膜脑脊髓炎患儿，伴或不伴脑脊液鼻窦炎。放射线扫描包括所有病例的CT扫描和MRI扫描，以描绘软组织和骨结构。所有儿童均接受内窥镜切除脑脊液并修复颅底缺损。结果作者成功治疗了14例。成功的病例包括4名年龄小于6个月的儿童，他们接受了单层旋转的隔粘膜皮瓣，从而避免了供体部位的发病。结论由于鼻内脑膨出的内窥镜切除是一种行之有效的治疗方法，因此作者通过微创手术的单层修复成功地将微创手术的概念进一步推进了一步。血管化的隔膜黏膜瓣似乎是成功修复先天性脑膜脑膨出的唯一决定性因素。但是，一项包含更多患者子集的前瞻性研究将证实这一假设。
