Facial paralysis (facial paralysis) is the development of loss of movement in facial expression muscles due to nerve damage.⠀ ⠀ Facial paralysis is divided into two.⠀ ⠀ 1- Facial paralysis (central) due to damage to the brain; It may also show other symptoms such as loss of retention in other parts of the body, brain damage, or stroke.⠀ ⠀ 2- Facial paralysis due to environmental injuries; It is called facial paralysis that occurs in facial nerve diseases after the brainstem. Peripheral facial paralysis is very common and occurs in only one half of the face.⠀ ⠀ As the facial nerves leave the brain and reach the face, they pass through a narrow canal inside the ear. They come out from the front of the ear and distribute to the facial muscles. In daily life, paralysis (Bell’s Paralysis) is most commonly seen due to nerve compression in the canal due to cold and viral diseases. Facial paralysis can be caused by inflammation of the inner ear canal, dental infections especially in the upper jaw, facial and head traumas, some congenital diseases and nerve damage during birth, viral diseases, tumors, diabetes, hyper/hypothyroidism, pregnancy, hypertension, toxic causes, post-operative and cold. It may be caused by prolonged exposure to air drafts. ⠀ ⠀ In peripheral facial paralysis, movements such as raising eyebrows, closing eyes, showing teeth, laughing, and puffing out cheeks are impaired. Apart from this, symptoms such as decreased tearing, decreased salivation, impaired sense of taste, and increased sensitivity to noise may be present. In central facial paralysis, eye and forehead movements are not affected, only the nose wings and lip branches are affected. Additional findings may be seen depending on the main cause of facial paralysis. ⠀ ⠀ Facial paralysis is a rapidly progressive disease and can reach its maximum severity in a few hours or a few days. Sometimes there may be an earache before a stroke. ⠀ ⠀ The most valuable finding for the diagnosis of a patient presenting with facial paralysis is the examination. The degree of damage on the affected side of the patient is determined by facial expressions. It is also appropriate to perform an MRI examination.⠀ ⠀ The more nerve damage, the longer the recovery process. In this case, it is beneficial to start treatment within 24-48 hours. The most effective agent in treatment is Cortisone.
