The aim of this study was to describe clinical features of Bell’s palsy (BP) in children and outcomes of physical therapy interventions. Medical records of 186 patients with diagnosis of BP were reviewed. The severity of facial nerve dysfunction was graded according to House Brackmann Facial Nerve Grading Scale (HB FGS). After one month, patients who had HB FGS grade three or more were included in a physical therapy programme consisting of superficial heat, massage, exercises, and electrical stimulation. Among 186 children with BP, 167 children had a severity of HB FGS grade three or more and 19 had the incomplete type at the time of the diagnosis. After one month follow-up, 144 patients fully recovered, 35 patients recovered partially, while 7 patients had no recovery. Patients who had not fully recovered one month after onset of paralysis were included in the physical therapy programme. There was statistically significant difference between pretreatment and posttreatment HB FGS scores in patients who had not fully recovered one month after onset of paralysis. We concluded that the prognosis of BP in children seems to be good with higher recovery rate and physical therapy programme might be an effective method to facilitate recovery in patients with poor prognosis. 1. Introduction The most common type of facial paralysis in children is Bell’s palsy (BP), which is defined as an acute, idiopathic, unilateral paralysis of the facial nerve without any associated disorders. Known congenital, genetic, and acquired causes of facial nerve paralysis need to be ruled out before the diagnosis of BP is made [1]. It has an incidence rate of 18.8 cases per 100.000 in children younger than 18 years old [2]. BP is an important cause of disability in some pediatric patients with major facial dysfunction and reduced quality of life [3]. Facial functions are multidimensional, serving emotional, social, and physical aspects of a person’s health. Incomplete recovery from facial nerve damage has significant social and psychological consequences. The prognosis of BP in pediatric population is generally good with a high rate of recovery. In spite of high complete recovery rate, some patients with BP do not achieve even satisfactory recovery. Moreover children with complete facial palsy and absence of recovery within 3 weeks may suffer poor outcomes as frequently as adults [4, 5]. In contrast with adults, the natural course of BP in children is not well documented and there are still many unresolved issues regarding the treatment and prognosis. Even though the treatment and
