The Seow Operative Score (SOS) as a decision-making adjunct for paediatric Chiari I malformation: a preliminary study

Management of Chiari I deformity in Children and Adolescents: A report from the Consensus Taskforce of the Brazilian Society of Pediatric Neurosurgery

“…For this purpose, clinical manifestations were divided into major and minor, in accordance with several published studies. 1,[20][21][22][23][24] Major clinical symptoms and signs are considered strong indicators for surgery, whereas minor ones should be accompanied by other indicative signs and dealt with on an individual basis.…”

“…From a radiological standpoint, as indications for surgery, along with the presence of a 5 mm tonsillar ectopia, 25,26 the following findings could help in the surgical decision 21 : presence of syrinx, presence of hydrocephalus, and cerebrospinal fluid (CSF) flow disturbance around the foramen magnum (especially on Cine-MRI scans and flow-related sequences).…”

“…In the cases where symptoms did not subside, indications for reoperation included persistence of syringomyelia, [20][21][22] persistent cranial nerves palsies 24,25 and other neurological symptoms. Children < 3 years old appear to have worse outcomes.…”

Precise Management of Chiari Malformation with Type I

“…Another role model of a prognostic scoring system for outcome of patients with CM-I is the Chiari Severity Index (CSI) which was put forward by Greenberg et al ( 32 ). Subsequently, Seow Operative Score was applied for decision-making intervention for pediatric CM patients in 2019 ( 33 ). In addition, the recent novel score termed SHORE was advocated by Feghali et al ( 34 ), which is a new predictive tool for improvement in adult CM-I after decompression surgery.…”
