Introduction: Advances in neonatal and pediatric intensive care have improved patient survival rates, emphasizing the need for respiratory support in cases of chronic respiratory failure, resulting in the establishment of the Turkish National Pediatric Patients Receiving Home Mechanical Ventilation (HMV) Support Registration System in 2023. This study aims to present the initial findings of the registry.

Methods: In this cross-sectional study, epidemiological and demographic data was obtained from the registry and compared between invasive ventilation (IV) and non-invasive ventilation (NIV) groups.

BACKGROUND Chiari malformation type 1 occurs when the cerebellar tonsils are pushed into the spinal canal, which can result in syringomyelia. This retrospective study from a single center evaluated outcomes in 89 patients with Chiari malformation type-I (CM-I) and syringomyelia treated with an arachnoid-preserving technique between 2016 and 2023. MATERIAL AND METHODS A retrospective analysis was conducted at a tertiary referral center, involving 88 adult patients and 1 adolescent patient aged 14 to 61 years, with diagnosis by MRI and treated for CM-I with syringomyelia between 2016 and 2023, using the arachnoid-preserving technique.
