Malformation BrainCHDSBNCT05913297
Neuroradiology Assesses Chiari Malformation's Impact on Airways, Cranial Base, and Sleep Disorders in Children.
An observational study of Malformation Brain, run by Fondazione Policlinico Universitario Agostino Gemelli IRCCS at 1 site in Italy.
Trial summary
The severity of sleep disorders in patients with Chiari malformations can vary. The investigators propose to establish a correlation between the severity of sleep-disordered breathing (SDB) and the quantitative neuroradiological data of the airways, cranial base foramina, and posterior cranial fossae Read more about this study

About this study
Official title: Quantitative Neuroradiological Assessment of the Airways, Cranial Base Foramina, and Posterior Cranial Fossae in Children with Chiari Malformation: Relationship with Sleep Disorders
The severity of sleep disorders in patients with Chiari malformations can vary. The investigators propose to establish a correlation between the severity of sleep-disordered breathing (SDB) and the quantitative neuroradiological data of the airways, cranial base foramina, and posterior cranial fossae
Read the detailed description
Primary objective of the study is the evaluation of sleep-disordered breathing (SDB) in two distinct pediatric populations of patients with Chiari Malformation Type 1 (CM-I) and Chiari Malformation Type 2 (CM-II).
Secondary objectives:
Stratify the presence of SDB into central and obstructive origins in the two study populations.
Assess the volume of posterior cranial fossae, airway volume, and area of cranial base foramina in both groups.
Determine the relationships between SDB and morphological-quantitative anomalies associated with CM.

Questions about this trial
What is this clinical trial studying?
An observational study of Malformation Brain, run by Fondazione Policlinico Universitario Agostino Gemelli IRCCS at 1 site in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 27 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Rosalinda Calandrelli, MD (3385417971 ext. +39, rosalinda.calandrelli@policlinicogemelli.it), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
prevalence of SDB (time frame: 3 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Feb 2025; AzTrials last refreshed its copy on 8 Nov 2026.
