Uncommon Bilateral Idiopathic Facial Nerve Palsy (Bell's Palsy) in an Infant: An Atypical Age and Clinical Challenges Explored: A Case Report.

ABSTRACT

Our case study explores Bell's palsy, a rare lower motor neuron facial nerve paralysis, particularly rare in newborns. While often idiopathic, it can stem from congenital or developmental factors. Unilateral facial paralysis is more prevalent, with Bell's palsy accounting for more than 50%, while bilateral facial paralysis is exceptionally rare. We present a distinctive case of idiopathic Bell palsy in a 3.5-month-old infant, initially affecting the right side and spontaneously resolved within 30 days, followed by involvement on the left side a month later. Despite comprehensive evaluations and treatment, persistent facial weakness was observed on the left side. The patient initially responded well but faced ongoing challenges during the second attack. Our findings underscore the need for further research to improve the understanding and management of these cases.
