The most common causes of facial paralysis are Bell's palsy (60-75% idiopathic), infections, neuropathies, neoplasia, trauma, and congenital conditions. Methodology: This study is a simple review that accounted for the secondary data gathered from different sources, including databases. specialist organizations' reports (records of hospitals), articles, and earlier research done in Saudi Arabia and particularly in the healthcare facilities. The study aimed to review and identify the relevant literature that reported the prevalence of facial paralysis among their population with the possible prognostic factors. Conclusion: Our study indicated that the incidence rate of facial paralysis in Saudi Arabia is relatively rare and it gets lower rates among children. It also reported that most of the cases were exposed to cold air currents or experienced hearing loss, while the cases among children were mostly post-stroke facial paralysis or vascular ischemia. It is worth mentioning that there is a significant lack in the studies that assess the psychological state of facial paralysis patients and evaluate the outcomes and possible complications.
