Study Notes
Left Facial Nerve Palsy
- Characterized by preserved function in the upper face, indicating intact innervation.
- Loss of nasolabial fold results in a smoother appearance on that side.
- Mouth deviation towards the unaffected (normal) side when smiling or grimacing.
Right Facial Nerve Palsy
- Exhibits loss of frontal wrinkling, demonstrating weakness in forehead muscle control.
- Bell's phenomenon, where the eye on the affected side moves upward when closing, is typically observed.
- Similar to left palsy, loss of nasolabial fold is present, contributing to facial asymmetry.
- Mouth also deviates towards the unaffected side, reflecting muscle weakness on the affected side.
