Summary

The House-Brackmann (H-B) and Burres-Fisch Linear Measurement Index (B-F LMI) systems for grading facial function show high correlation. Combining both subjective and objective measures offers the best current approach for evaluating facial palsy.

Area of Science:

  • Otolaryngology
  • Neurology
  • Medical Diagnostics

Background:

  • Established systems for reporting facial function test results remain suboptimal.
  • The American Academy of Otolaryngology-Head and Neck Surgery adopted the House-Brackmann (H-B) scale in 1985.
  • The Burres-Fisch Linear Measurement Index (B-F LMI) was proposed as an objective alternative in 1986.

Purpose of the Study:

  • To evaluate the efficacy of the H-B and B-F LMI systems in grading facial function.
  • To compare the relative merits of subjective (H-B) versus objective (B-F LMI) grading systems.
  • To determine the correlation between these two widely used facial palsy assessment tools.

Main Methods:

  • Studied 41 patients with facial weakness and one normal patient.

Related Experiment Videos

  • Assessed facial function using both the H-B subjective grading scale and the B-F LMI objective system.
  • Analyzed the correlation between the results obtained from both grading systems.

    • Main Results:

    • The H-B system is user-friendly with clear criteria for each grade.
    • The B-F LMI system is more complex, time-consuming, and requires intricate calculations.
    • A high degree of correlation was observed between the subjective H-B scale and the objective B-F LMI system.

    Conclusions:

    • Despite differences in methodology (subjective vs. objective), both systems demonstrate strong agreement in grading facial function.
    • The authors recommend combining the H-B and B-F LMI systems for comprehensive facial function evaluation.
    • This combined approach represents the most effective method for assessing patients with facial palsy currently available.
