Diagnosis of Facial Nerve Paralysis

A. Clinical Diagnosis

1. Paralysis Assessment:
   • Complete: No detectable movement in facial muscles.
   • Incomplete: Any detectable movement in facial muscles.
2. Classification: Determine if UMNL or LMNL as previously described.

B. Electrical Diagnosis

1. Nerve Excitability Test (NET) - Minimal Stimulation Test
2. Maximal Stimulation Test (MST)
3. Electroneurography (ENOG)
4. Electromyography (EMG)

C. Anatomical “Topographical” Diagnosis
