To explore and evaluate the methodology of neuro-endoscope assisted atlanto occipital decompression in Chiari type I malformation with syringomyelia.
Between January 2007 to January 2008, 8 patients underwent neuro-endoscope assisted atlanto occipital decompression, including 2 male patients and 6 female patients (aged 13 to 52 years). During the operations, the surgical fields were lightened by the illuminator of endoscope. All the manipulations were done outside the sheath of neuroendoscope. The decompression bone window was about 2.0 cm × 2.0 cm. After the atlanto occipital fascia was cleared thoroughly, dura were opened in 6 cases and intact in 2 cases.
There were no complications observed in this study. Seven patients were determined as excellent in recovery according to the Tator criteria because of apparent improvements in superficial sensation. Five of the seven patients had improvements in muscle strength. One patient was assessed as good because of stable symptom without deterioration.
Neuro-endoscope assisted atlanto occipital decompression is a potential technique worthy of employing in the mini-invasive neurosurgical technology.
探讨和评估神经内镜辅助下寰枕减压术治疗Ⅰ型Chiari畸形合并脊髓空洞症的方法。
2007年1月至2008年1月，8例患者接受神经内镜辅助下寰枕减压术，其中男性2例，女性6例（年龄13至52岁）。手术过程中，内镜照明使术野清晰。所有操作均在神经内镜鞘外进行。减压骨窗约为2.0 cm×2.0 cm。彻底清除寰枕筋膜后，6例打开硬脑膜，2例硬脑膜完整。
本研究未观察到并发症。根据Tator标准，7例患者因浅感觉明显改善而恢复良好。7例患者中有5例肌力有所改善。1例患者因症状稳定无恶化被评估为良好。
神经内镜辅助下寰枕减压术是一种值得在微创神经外科技术中应用的潜在技术。
