facial weakness

could it be an acute stroke?

features that suggest stroke rather than facial nerve palsy

  • any one or more of:
    • new weakness of arm or leg
    • new dysphasia
    • sparing of the forehead muscles (eg. forehead folds persist)
      • although if patient has had forehead Botox this may hide this sign
    • new involvement of other cranial nerves
      • eg. deafness + Horner's suggests a dorsolateral pons lesion due to superior cerebellar artery infarction

if suspect stroke

  • if onset within past 4hrs:
    • acute stroke call
    • urgent CT brain
  • Mx as per stroke (CVA)

if no evidence of stroke and likely to be facial nerve palsy
