Facial nerve paralysis: As a Doctor, we know that facial nerve paralysis or Bell’s palsy is a form of facial paralysis resulting from a disfunction of the cranial nerve 7 causing an inability to control facial muscles on the effective side. Often the eye on the affected side cannot be closed. The eye must be protected from drying up or the denture wearer’s cornea may be permanently damaged, resulting in impaired vision. In some cases, denture wearers experience some discomfort. The common presentation of this condition is a rapid onset of partial or complete paralysis that often occurs overnight. In rare cases, it can occur on both sides resulting in total facial paralysis.
What Is Facial nerve paralysis?
Facial nerve paralysis or Bell’s palsy is a form of temporary facial paralysis resulting from damage or trauma to the facial nerves. The facial nerve also called the seven cranial- travels through a narrow, bony canal in the skull, beneath the ear, to the muscles on each side of the face. For most of its journey, the nerve is encased in this bony shell.
Each facial nerve directs the muscles on one side of the face, including those that control blinking and closing and facial expressions such as smiling and frowning. Additionally, the facial nerve carries nerve impulses to the lacrimal or tear glands, The Saliva glands, and the muscles of the small bone in the middle of the ear called the stapes. The facial nerve also transmits taste sensations from the tongue.
Classification of the facial nerve according to the place:
Classification: Facial nerve paralysis 3 types
Causes of facial paralysis
Causes of facial paralysis: There are different causes of facial nerve paralysis. We discuss below now-
Accumulation of excess phlegm in the midbrain is an important cause of bells palsy occurs when the nerve that controls the facial muscles is swollen, inflamed, or compressed, resulting in facial weakness or paralysis. Exactly what causes this damage, however, is unknown Most scientists believe that a viral infection such as viral meningitis or the common cold sore virus-herpes simplex causes this order. They believe that the facial nerves swell and become inflamed in reaction to the infection, causing pressure within the fallopian canal and leading to ischemia. In some mild cases, there is damage only to the myelin sheath of the nerve. The myelin sheath is the fatty covering that acts as an insulator- on nerve fibers in the brain.
The disorder has also been associated with influenza or a flu-like illness, headache, chronic middle ear infection, high blood pressure, diabetes, sarcoidosis, tumors, Lyme disease, and trauma such as skull fracture or facial injury.
what are the signs- and symptoms of facial nerve paralysis?
Signs- symptoms of facial nerve paralysis: Facial nerves control blinking, opening and closing of the eyes, smiling, salivation, lacrimation, and frowning. They also supply the stapes muscles’ nerves. The stapes is a bone in the ear that is involved in our ability to hear. when the facial Muscles Malfunction, the following symptoms of Bell palsy
