Background

Chiari malformation type I (CM-I) often leads to syringomyelia (syringomyelia) through impaired cerebrospinal fluid (cerebrospinal fluid) flow at the craniocervical junction, resulting in progressive neurological deficits.

Results

< 3 mm

residual cavity nearly gone, syrinx almost fully resolved

More results

She underwent suboccipital craniectomy, C1 laminectomy, bilateral subpial tonsillectomy, and expansile duraplasty with autologous fascia lata graft.

Intraoperative Valsalva confirmed restored cerebrospinal fluid flow.

Postoperatively, headaches and neck pain resolved immediately.

“

Conclusion

This case demonstrates the efficacy of a comprehensive surgical approach incorporating bilateral tonsillectomy in severe CM-I with extensive syringomyelia, yielding rapid radiological and clinical improvement within 3 months.
