神经内镜下寰枕部减压手术治疗Chiari畸形

目的 探讨神经内镜下寰枕减压手术治疗Chiari畸形的手术方法和临床疗效.方法 对23例经MRI确诊为Chiari畸形但不伴有寰枢锥脱位和齿突凹陷的患者在神经内镜下进行了寰枕减压手术,并进行疗效观察.结果 23例术后随访0.5-3.0年,原有症状均有不同程度改善,感觉障碍程度减轻,肢体肌力有所增强.无手术后并发症.术前合并脊髓空洞症的16例患者中,术后7例空洞消失,8例范围缩小,1例范围无明显变化.结论 神经内镜下寰枕减压手术治疗Chiari畸形方法可行,手术安全、有效、创伤小、疗效满意.

Abstract：

Objective To investigate the methods and effectiveness to treat Chiari malformation with the surgical decompression of the foramen magnum under endoscope. Method 23 cases with Chiari malformation.(without atlanto- axialdislocation and basilar invagination) diagnosed by magnetic resonance imaging( MRI)were operated with the surgical decompression of the foramen magnum under the endoscope. Results 23 cases were followed- up 0. 5 -3. 0, years after operation, all the symptoms and signs were remarkably relieved after the operation. No complications was found. In 16 cases with spinal cavities,7 cases spinal cavities disappeared and scases deflated,l case no evident change. Conclusions The endoscope -assisted decompression of the foramen magnum is a safe and effective surgical method to treat Chairi malformation.
