ABSTRACT

Objective:To study the different modus operandi of posterior fossa decompression on function recovery of spine cord in patients with Chiari malformation and syringomyelia.Methods:Of 87 patients with Chiari malformation and syringomyelia,51 patients were selected and big craniectomy was performed in all cases.The effects of big craniectomy in 51 patients and mini craniectomy in 36 patients were compared.Results:Among the 51 patients,22 patients(43.1%) improved significanly in their clinical symptoms,10 cases were stabilized,and 5 cases deteriorated.Among the 36 patients,28 patients(77.8%) improved significanly in their clinical symptoms,and 3 cases were stabilized.Conclusion:Surgical treatment may fully ameliorate the clinical syndromes.Mini craniectomy and expansile reconstruction of posterior fossa is a preferred surgery for the treatment of ChiariⅠmalformation.
