    Bell's palsy patients show a higher frequency of diabetes mellitus (24.8%), arterial hypertension, and lipid disturbances. These conditions suggest an ischemic cause for facial paralysis, potentially linked to diabetic small vessel disease.

    Area of Science:

    • Neurology
    • Endocrinology
    • Vascular Medicine

    Background:

    • Bell's palsy (idiopathic peripheral facial paralysis) prevalence varies among diabetic patients.
    • Understanding the underlying pathogenesis of Bell's palsy is crucial for effective management.

    Purpose of the Study:

    • To investigate the frequency of diabetes mellitus and other comorbidities in Bell's palsy patients.
    • To explore the potential pathogenetic mechanisms, particularly ischemic versus metabolic, in Bell's palsy.

    Main Methods:

    • A case-control study design was employed.
    • Compared the frequency of diabetes mellitus, arterial hypertension, and lipid disturbances in Bell's palsy patients versus controls.
    • Assessed taste impairment differences between diabetic and non-diabetic Bell's palsy patients.

    Main Results:

    • A 24.8% frequency of diabetes mellitus was observed in Bell's palsy subjects.
    • Arterial hypertension and lipid disturbances were more prevalent in Bell's palsy patients than controls.
    • Diabetic patients with Bell's palsy exhibited significantly less taste impairment compared to non-diabetics.

    Conclusions:

    • Findings suggest a predominantly ischemic pathogenesis for most idiopathic peripheral facial paralysis cases.
    • Reduced taste impairment in diabetics supports a vascular rather than metabolic basis for Bell's palsy.
    • Diabetic small vessel disease may predispose individuals to facial nerve decompensation and paralysis.
