FROWN: idiopathic gradual onset facial palsy with no other diagnoses


  • Gradual onset facial palsy with unremarkable medical and radiographic evaluations over several years may be classified as FROWN (facial palsy, radiographic and other workup negative), which can be treated with facial reanimation surgery.

Why this matters

    Slow onset, progressive facial palsy with extensive negative medical, radiographic, and surgical results is a rare occurrence; recognizing this condition and potential treatments will improve patient quality of life.
