Diagnosis and treatment of Chiari type 1 malformation (report of 99 cases)

Objective To investigate the diagnosis and treatment of Chiari type 1 malformation (C1M). Methods The clinical data of 99 patients with C1M who were admitted to our hospital from February 2015 to June 2022 were retrospectively analyzed. Of 99 patients, 19 patients received conservative treatment and 80 patients received surgery. All patients were followed up for 1 year. Results Of 19 patients receiving conservative treatment, symptoms were improved in 2 patients (10.5%), not changed in 16 (84.2%), and worsened in 1 (5.3%). Of 80 patients receiving operation, symptoms were improved in 69 patients (86.3%), not changed in 10 patients (12.5%), and 1 patient (1.2%) died of acute respiratory failure. Conclusions The diagnosis of C1M mainly depends on clinical and imaging manifestations. Surgical treatment, which is more effective than conservative treatment, is the main treatment methods for C1M.
