目的探讨治疗ChiariⅠ畸形手术疗效及术后并发症的方法。方法 40例ChiariⅠ型畸形患者均采用手术治疗。随机分成2组,其中观察组20人(A组):单纯后颅窝骨性减压+环枕筋膜松解术。对照组20人(B组):后颅窝减压加小脑扁桃体疝切除术。结果 2组手术方法均可达到治疗ChiariⅠ畸形的目的,并无明显疗效差异。但术后观察组并发症明显少于对照组,两组相较,差异显著(P<0.05)。结论 2组后颅窝减压术均可达到治疗Arnold-ChiariⅠ畸形的目的,且疗效无明显差异;但单纯后颅窝骨性减压+环枕筋膜松解术可明显减少相关并发症的发生,值得推广。
Objective To investigate the curative effect and postoperative complications of Chiari Ⅰ deformity. Methods 40 patients with Chiari Ⅰ deformity were treated by surgery. Randomly divided into 2 groups, of which 20 were observed group (A group): simple posterior fossa osteoclasty + lobe fascia lysis. Control group of 20 (B group): posterior fossa decompression plus cerebellar tonsillectomy. Results The two groups of surgical methods can achieve the purpose of treatment of Chiari Ⅰ deformity, and no significant difference in the efficacy. However, postoperative complications in the observation group were significantly less than those in the control group, with significant differences between the two groups (P <0.05). Conclusions The posterior fossa decompression can achieve the purpose of treating Arnold-Chiari Ⅰ deformity without any significant difference between the two groups. However, the posterior fossa decompression combined with the ring closure of the occipitocervical fascia can significantly reduce the related complications Occurs, it is worth promoting.
