Signs of facial nerve damage
Lyme disease, caused by chronic Borrelia burgdorferi infection, is a common cause of facial nerve paralysis in endemic areas. 4 Trauma edit Physical trauma, especially fractures of the temporal bone, may also cause acute facial nerve paralysis. Understandably, the likelihood of facial paralysis after trauma depends on the location of the trauma. Most commonly, facial paralysis follows temporal bone fractures, though the likelihood depends on the type of fracture. Transverse fractures in the horizontal plane present the highest likelihood of facial paralysis (40-50). Patients may also present with blood behind the tympanic membrane, sensory deafness, and vertigo ; the latter two symptoms due to damage to vestibulocochlear nerve and the inner ear. Longitudinal fracture in the vertical plane present a lower likelihood of paralysis (20). Patients may present with blood coming out of the external auditory meatus tympanic membrane tear, fracture of external auditory canal, and conductive hearing loss.discharge ( otorrhea or hearing loss, with or without ear pain ( otalgia ). Once suspected, there should be immediate surgical exploration to determine if a cholesteatoma has formed as this must be removed if present. Inflammation from the middle ear can spread to the canalis facialis of the temporal bone - through this canal travels the facial nerve together with the steatoacoustisus nerve. In the case of inflammation the nerve is exposed to edema and subsequent high pressure, resulting in a periferic type palsy.
4 :2585, bell's palsy edit, main article: Bell's palsy, bell's palsy is the most common cause of acute facial nerve paralysis. There is no known cause of Bell's palsy, 3 4 although it has been associated with herpes simplex infection. Bell's palsy may develop over several days, and may last several months, in the majority of cases recovering spontaneously. It is typically diagnosed clinically, in patients with no risk factors for other causes, without vesicles in the ear, paper and with no other neurological signs. Recovery may be delayed in the elderly, or those with a complete paralysis. Bell's palsy is often treated with corticosteroids. 3 4, infection edit, reactivation of herpes zoster virus, as well as being associated with Bell's palsy, may also be a direct cause of facial nerve palsy. Reactivation of latent virus within the geniculate ganglion is associated with vesicles affecting the ear canal, and termed Ramsay hunt syndrome type. 4 In addition to facial paralysis, symptoms may include ear pain and vesicles, sensorineural hearing loss, and vertigo. Management includes Antiviral drugs and oral steroids. Otitis media is an infection in the middle ear, which can spread to the facial nerve and inflame it, causing compression of the nerve in its canal.

Facial nerve paralysis is a common problem that involves the paralysis of any structures innervated by the facial nerve. The pathway of the facial nerve is long and relatively convoluted, so there are a number of causes that may stockists result in facial nerve paralysis. 2, the most common is, bell's palsy, a disease of unknown cause that may only be diagnosed by exclusion. Contents, signs and symptoms edit. Facial nerve paralysis is characterised by unilateral facial weakness, with other symptoms including loss of taste, hyperacusis and decreased salivation and tear secretion. Other signs may be linked to the cause of the paralysis, such as vesicles in the ear, which may occur if the facial palsy is due to shingles. Symptoms may develop over several hours. 3 :1228 Acute facial pain radiating from the ear may precede the onset of other symptoms.

Stroke or Cerebrovascular Accident (cva a stroke occurs when blood supply to a part of the brain is disrupted due to any cause. This causes death of the brain cells by depriving them of oxygen. The symptoms depend upon the area of brain that is affected and the degree of brain tissue damage.

Difficulty in closing the eye on the affected side. Inability to wrinkle the forehead. Pain around or in the ear. Sounds seem louder on the affected side (hyperacusis). Hyperlacrimation or excessive watering of the eye on the affected side.

Causes of Facial Droop, causes of facial droop are innumerable but the ones most commonly encountered goji are : Bells Palsy, thi is one of the most common causes of a facial droop.

It is usually a unilateral condition meaning that it only affects one side. The herpes simplex virus, which causes cold sores and genital herpes, is most often involved. Diabetics, pregnant women and people with upper respiratory tract infections are more at risk of suffering from Bells palsy and the incidence increases with age. Other Signs and Symptoms of Bells Palsy. Sudden onset of facial paralysis or weakness involving one side of the face facial droop. Difficulty with smiling or other facial expressions.
Facial Nerve, the facial nerve is one of the 12 cranial nerves that emerge directly from the brain. Marked as cranial nerve 7 (vii the facial nerve exits the brain, giving off branches along its way to the parotid gland where it divides into five smaller nerves. The facial nerve is responsible for motor, sensory and parasympathetic functions of structures in the head. Motor, facial muscles, stapedius muscle, sensory. Anterior two-thirds of the tongue, parasympathetic, salivary and lachrymal glands. By controlling the facial muscles, the facial nerve allows us to change our facial expression, showing different emotions and assisting with talking and chewing to some degree. Its innervation of the stapedius muscle, a small muscle that stabilizes the stapes in the ear, allows it to control our perception of sound volume. The facial nerves sensory functions in the anterior two-thirds of the tongue makes it responsible for the taste sensation in this area. The salivary glands and lacrimal (tear) glands are also partly controlled by the facial nerve, which can essentially turn off these glands when necessary.

Facial droop is sagging of the face caused by loss of facial olijfolie muscle tone. This is usually caused by an impairment of nerve function that supply the facial muscles, particularly involving the facial nerve. Most cases of facial droop are one-sided (unilateral) causing a distortion of the normal face structure. This typically appears like the lips are being pulled on one side and there may be difficulty in closing the eye or impairment of the taste sensation. A number of factors can contribute to a facial droop, including trauma, infections and other systemic pathologies. Facial droop in this context is not related to a sagging facial skin, which may occur as a result of loss of elasticity of the skin. In these cases, a sagging face may be age-related, occur after a sudden loss of weight, debilitating illness or in cases of drug abuse, like a crystal meth addiction.
