    A thorough clinical evaluation is key for diagnosing peripheral facial nerve dysfunction. A tailored approach to computed tomography (CT) scans can prevent unnecessary tests and speed up diagnosis for occult causes.

    Area of Science:

    • Neurology
    • Radiology
    • Otolaryngology

    Background:

    • Peripheral facial nerve dysfunction can stem from identifiable or hidden causes.
    • Current diagnostic practices may involve inadequate clinical assessment before imaging.
    • Unnecessary computed tomography (CT) examinations are frequently observed.

    Purpose of the Study:

    • To analyze the diagnostic workup for peripheral facial nerve dysfunction.
    • To identify patterns of inadequate clinical evaluation and unnecessary radiographic testing.
    • To propose an optimized clinical and radiographic scheme for evaluating occult facial nerve dysfunction.

    Main Methods:

    • Retrospective review of clinical and radiographic records of 36 patients.
    • Analysis of lesion localization, radiographic test sequence, and type.

  • Evaluation of the thoroughness of pre-CT clinical assessments.

    • Main Results:

    • Inadequate clinical evaluations preceded CT in some cases.
    • Unnecessary CT examinations were performed.
    • A clear clinical-radiographic approach is evident when the cause is apparent.
    • A tailored CT strategy is needed for occult causes, guided by clinical findings.

    Conclusions:

    • A systematic clinical evaluation is crucial for diagnosing peripheral facial nerve dysfunction.
    • A tailored CT examination, based on clinical findings, is recommended for occult cases.
    • Implementing a practical clinical and radiographic scheme can reduce unnecessary tests and diagnostic delays.
