    This case study details a nine-year-old girl with persistent right hemifacial spasm (HFS). Investigations and initial treatment were unsuccessful, highlighting the rarity of childhood HFS.

    Area of Science:

    • Neurology
    • Pediatric Neurology

    Background:

    • Hemifacial spasm (HFS) is a neurological disorder characterized by involuntary contractions of facial muscles.
    • While typically affecting adults, HFS in childhood is rare, with limited reported cases.

    Observation:

    • A nine-year-old girl presented with a 27-month history of right-sided hemifacial spasm.
    • Facial muscle synkinesis was observed upon stimulation of the right supraorbital nerve.
    • Blink reflex latency and amplitude were bilaterally symmetrical.

    Findings:

    • Computerized tomography (CT) scans were unremarkable.
    • Pharmacological treatment with carbamazepine proved ineffective in managing the hemifacial spasm.
    • This represents the third documented instance of hemifacial spasm occurring in a pediatric patient.

    Implications:

    • The case underscores the diagnostic challenges and limited treatment options for hemifacial spasm in children.
    • Further research into the etiology and management of pediatric hemifacial spasm is warranted.
    • Highlights the need for considering rare neurological conditions in pediatric differential diagnoses.
