Summary
The Facial Nerve Function Index (FNFI) has a skewed distribution. A new Facial Nerve Function Coefficient (FNFC) offers a symmetrical alternative for assessing facial nerve palsy recovery.
Area of Science:
- Neurology
- Ophthalmology
- Plastic Surgery
Background:
- Facial nerve palsy impacts facial movement symmetry.
- The Facial Nerve Function Index (FNFI) is used to monitor recovery.
- The FNFI exhibits a skewed distribution due to its formulation.
Purpose of the Study:
- To address the inherent asymmetry in the FNFI.
- To propose a modified index, the Facial Nerve Function Coefficient (FNFC).
- To obtain a symmetrical distribution for improved assessment.
Main Methods:
- Formulation of the modified Facial Nerve Function Coefficient (FNFC).
- Analysis of the FNFC distribution for symmetry.
- Derivation of a reference range for the FNFC.
Main Results:
- The proposed FNFC demonstrates a symmetrical distribution.
- The FNFC effectively removes the inherent asymmetry of the FNFI.
- A reference range for the FNFC was successfully established.
Conclusions:
- The FNFC provides a more accurate and symmetrical measure of facial nerve function.
- This modified index is suitable for monitoring patients with facial nerve palsy.
- The FNFC offers a statistically improved tool for clinical assessment.
