ABSTRACT: Bell’s palsy, sometimes referred to as “acute facial palsy of unknown cause,” is a frequent cranial neuropathy that typically affects one side and causes sudden, full paralysis or facial muscular paresis. The condition can worsen over the course of 48 hours. It is caused by malfunction of the facial nerve as a result of injury or inflammation to the facial nerve, the 7th cranial nerve, or any of its branches along its path, mostly in the bony canal. It affects both sexes equally, and while there is no age limit, the incidence increases with age. The goal of this review article is to offer a thorough overview of Bell’s palsy, covering its clinical presentation, epidemiology, and the use of a variety of treatment methods, such as corticosteroids, antiviral medications, physical therapy, and surgical procedures, is explored, with an emphasis on the evidence-based guidelines and related debates. Furthermore, new developments in the pathogenesis of Bell’s palsy and potential treatments are examined.
