The objective of this study was to present neural endoscopic posterior fossa decompression and atlas laminectomy for Chiari type I patients. Methods Twenty-one patients with Chiari type I underwent neural endoscopic posterior fossa decompression and atlas laminectomy. We described the procedure for neural endoscopic posterior fossa decompression and atlas laminectomy. All patients in this series demonstrated cerebellar tonsil herniation below the foramen magnum in addition to syringomyelia. All patients in the reviewed study underwent preoperative MRI as well as 3-month postoperative MRI. Additional follow-up MRI varied but was usually repeated 12 months to 18 months after surgery. Postoperative MRI studies were retrospectively reviewed and compared with preoperative studies. Results All patients showed clinical improvements, and none had any complications. Patients with syringomyelia had symptoms entirely disappear. Eleven patients （52.4%） experienced radiographic improvement in syringomyelia （decreased size or resolution） during the follow-up period. Nine patients （42.8%） demonstrated decreased syrinx size and four （19%） demonstrated resolved syrinx. Of the 15 patients with symptomatic syringomyelia, 11 （73.3%） experienced symptomatic improvement. The median time to symptom improvement was four months after surgery. Post surgical MRI examinations indicated complete and sufficient decompression of foramen magnum region. Conclusions Endoscope atlanto-occipital decompression surgery is an innovative, safe and effective surgical procedure. It has similar results compared to traditional surgery, however with the added advantages of being minimal invasive, having fewer complications, decreased influence on stability of occipital bony 展开更多

These structures are likely to be affected in Chiari malformation. Therefore, SEP abnormalities may provide valuable information in patients with CM. However, the consistency of SEP abnormality or normality with the damage is a matter of research. Knowing whether median nerve somatosensory evoked potential (SEP) is useful in revealing subclinical damage in patients with Chiari malformation is important in the treatment and follow-up plan of the disease. The aim of this study was to investigate the relationship between median nerve SEP values and the severity of cerebellar ectopia in patients with Chiari type 1 malformation. Median nerve SEP values were obtained from 30 healthy individuals and 146 individuals with Chiari malformation. The cerebellar ectopia degree and McRae line length were measured. SEP values were not significantly different between groups. The McRae line was found to be significantly shorter in the control group than in the Chiari malformation group (p = 0.031). There was no correlation between the degree of cerebellar ectopia and the length of the McRae line (r = 0.002, p = 0.979). Neither cerebellar ectopy degree nor McRae line length had a relationship with SEP values (r = -0.153, p = 0.066;r = -0.056, p = 0.500, respectively). There was no difference in cerebellar ectopy degree or SEP values between the groups with cerebellar ectopy with and without a syrinx (p = 0.899;p = 0.080, respectively). Likewise, McRae line length was not found to be related to the presence of a syrinx (p = 0.139). Median nerve SEP examination was not beneficial for diagnosing asymptomatic-oligosymptomatic Chiari malformation as a subclinical injury, whether accompanied by syringomyelia or not.展开更多
