Summary

The Cornea, Asymmetry, Dynamic, Synkinesis (CADS) score helps guide oculoplastic surgery for facial nerve palsy (FNP). Higher scores in specific CADS domains predict the need for upper and lower eyelid surgery, informing management decisions.

Area of Science:

  • Ophthalmology
  • Oculoplastics
  • Facial Nerve Palsy

Background:

  • Facial nerve palsy (FNP) significantly impacts periocular structures.
  • The Cornea, Asymmetry, Dynamic, Synkinesis (CADS) score is a validated tool for assessing FNP severity.
  • Oculoplastic management of FNP requires a structured approach.

Purpose of the Study:

  • To evaluate the utility of the CADS score in guiding oculoplastic interventions for FNP.
  • To develop a management algorithm for FNP based on CADS grading.
  • To correlate CADS domains with specific surgical needs in FNP patients.

Main Methods:

  • Retrospective cohort study of 80 adult FNP patients with ≥6 months follow-up.
  • Data collection included demographics, FNP etiology, treatment, and serial CADS grading.
  • Analysis focused on correlating initial CADS scores with subsequent surgical recommendations.

Main Results:

  • 75% of FNP cases had a preganglionic etiology; 98.8% were unilateral.
  • Initial surgery was recommended for 61.3% of patients.
  • Specific CADS domains (C, A, D) predicted the need for upper and/or lower lid surgery, while S-score did not correlate with surgical necessity.

Conclusions:

  • The CADS score effectively predicts surgical requirements in FNP.
  • A CADS-based management algorithm can guide oculoplastic decision-making.
  • This grading scale facilitates tailored surgical and medical management for FNP patients.
