Clinical prognostic factors associated with good outcomes in pediatric bell’s palsy

The prognosis of children with Bell’s palsy remains unclear due to its relatively low incidence, and thus, the small number of patients included in individual studies. To evaluate the prognosis of children with Bell’s palsy and identify the predictive value of specific factors that contribute to complete recovery, a retrospective cohort study was conducted of all patients with Bell’s palsy who visited the outpatient clinic of our university hospital between January 2005 and December 2020. We identified the parameters associated with a favorable recovery after 6 months in pediatric patients with Bell’s palsy. Factors recorded for each patient included age, sex, side affected by palsy, time between symptom onset and start of treatment, treatment methods, and the House–Brackmann grade (H–B) grade. The results of the multivariable analysis revealed that the lower degree of initial facial nerve paralysis presented as H–B grade II–IV was a significant favorable prognostic factor (OR: 3.86; 95% CI: 1.27–11.70; p < 0.05). Our results showed that the most important factor influencing the complete recovery of Bell’s palsy in children was the lower initial H–B grade at initial presentation.
