Millard-Gubler syndrome and Foville syndrome are both neurological conditions that involve specific cranial nerves and hemiplegia (paralysis on one side of the body). However, there are distinct differences between the two syndromes:

  1. Millard-Gubler Syndrome: This syndrome involves the involvement of the sixth cranial nerve (abducens nerve) and the seventh cranial nerve (facial nerve) on the same side of the brainstem lesion, resulting in ipsilateral (same side) abducens palsy and facial palsy. In addition to these cranial nerve deficits, Millard-Gubler syndrome is associated with contralateral (opposite side) hemiplegia or hemiparesis (weakness) affecting the limbs on the side opposite to the brainstem lesion. The underlying cause is usually a vascular event, such as a stroke, affecting the ventral (front) pons area.
  2. Foville Syndrome: Foville syndrome involves the involvement of the sixth cranial nerve (abducens nerve), the seventh cranial nerve (facial nerve), and the lower branches of the fifth cranial nerve (trigeminal nerve). The affected cranial nerves can be either ipsilateral or contralateral to the brainstem lesion. The characteristic findings of Foville syndrome include ipsilateral abducens palsy, ipsilateral facial palsy, and contralateral hemiplegia or hemiparesis affecting the limbs on the side opposite to the brainstem lesion. Similar to Millard-Gubler syndrome, Foville syndrome is typically caused by a vascular event affecting the ventral pons area.

In summary, the main difference between Millard-Gubler syndrome and Foville syndrome lies in the involvement of additional cranial nerves. Millard-Gubler syndrome involves ipsilateral abducens and facial nerve involvement, while Foville syndrome involves ipsilateral abducens, facial, and lower branches of the trigeminal nerve involvement. Both syndromes are characterized by hemiplegia on the side opposite to the brainstem lesion.
