    Third ventricular width variations were studied in patients with movement disorders who underwent thalamotomies. Narrower ventricles correlated with medial displacement of the thalamocapsular border, suggesting anatomical differences in these patients.

    Area of Science:

    • Neurosurgery
    • Neurology
    • Neuroanatomy

    Background:

    • Extrapyramidal movement disorders affect motor control.
    • Stereotactic thalamotomies are surgical interventions for movement disorders.
    • Third ventricular width can vary anatomically.

    Purpose of the Study:

    • To investigate variations in third ventricular width.
    • To correlate third ventricular width with patient demographics and surgical history.
    • To explore the relationship between third ventricular width and thalamocapsular border position.

    Main Methods:

    • Selection of 65 patients with extrapyramidal movement disorders.
    • Correlation analysis of third ventricular width with age, sex, diagnosis, and intercommissural distance.

  • Analysis of somatosensory response mappings to assess thalamocapsular border displacement.

    • Main Results:

    • Third ventricular width showed variations among the studied patients.
    • Correlation analysis revealed relationships between ventricular width and demographic/anatomical factors.
    • Medial displacement of the thalamocapsular border was observed in patients with narrow third ventricles.

    Conclusions:

    • Third ventricular width is a variable anatomical feature in patients with extrapyramidal movement disorders.
    • Narrow third ventricles are associated with a medial shift in the thalamocapsular border.
    • These findings may have implications for understanding neuroanatomy in movement disorder patients.
