Causes of facial palsy in adults
Bells palsy is the most common cause of fnp, composing nearly two-thirds of all cases. Bells palsy, bells palsy is typically a self-limited disorder and is felt to be the result of a viral-induced inflammation of the nerve sheath. The incidence of Bells palsy ranges from 10 to 40 cases per 100,000 with the highest rate occurring in individuals between 15 and 45 years of age 1012,17,18. Familial cases of cranial nerve vii palsy have been reported 16,19. The recurrence rate of Bells palsy has been recorded as high as 10 with women carrying a higher risk. Although 70 of untreated patients recover completely within 6 months 16, as many as 30 of patients may suffer from permanent facial dysfunction.by other nerves or different branches of the same nerve. In particular, aberrant regeneration of cranial nerve vii can result in facial synkinesis in approximately 10 of Bells palsy cases. Oral or ocular synkinesis can make communication difflcult and lead to copious lacrimation during eating(crocodile tears)6,8,9. Fnp can be caused by a variety of conditions including temporal bone fracture, head and neck tumors, and infections 1015. The following section will focus on the current literature on the medical management of idiopathic facial paralysis that is commonly referred to as Bells palsy.
In addition, improvement in surgical Current Opinion in Ophthalmology 2009, techniques has allowed the introduction of a number of surgical procedures for patients with permanent facial nerve palsy. Summary, on the basis of the results of several recently completed randomized, controlled studies, corticosteroid therapy has proven to be efficacious in the treatment of Bells palsy and should be offered to patients presenting within 72 hours of symptom onset with consideration to the addition. Surgical procedures can minimize the complications associated with permanent facial nerve palsy. Introduction, facial nerve palsy (FNP) describes the condition in which there is damage to cranial nerve vii, resulting in sensorimotor deflcits involving the muscles of the face and ocular adnexa. Cranial nerve vii consists of numerous individual nerve flbers that innervate muscles of the face, periorbita (orbicularis oculi and inner ear (stapedius muscle). Cranial nerve vii originates in the pons at the floor of the fourth ventricle and enters the temporal bone through the internal auditory canal (Fig. The nerve takes a circuitous route in the temporal bone and, upon exiting from the stylomastoid foramen, enters the parotid gland. At the parotid gland, it has a variable pathway but typically divides into an upper and lower division, ultimately forming a parotid plexus and splitting into flve motor branches. Conditions targeting any structures along the route of cranial nerve vii or the nerve itself from the brainstem through and out of the skull base may compromise function resulting in speciflc clinical manifestations. A lesion of the supranuclear corticobulbar pathway (central cranial nerve vii palsy) results in a contralateral lower facial paresis with intact upper facial function (including blink).

Purpose of review, to review the results of recently published studies on the medical management of Bells palsy and highlight strategies in the surgical management of facial nerve palsy. Recent Findings For Bells Palsy management. Although corticosteroid and antiviral therapy have been proposed for the treatment of Bells palsy for many years, the clinical efficacy of these treatments has been debated in Professor, departments make of Ophthalmology and the literature due to the lack of conclusive evidence from large-scale clinical trials. However, recently completed randomized, controlled studies have found that the early administration of corticosteroids improves the chances of full recovery in patients with Bells palsy. But there remains insufficient evidence supporting the routine use of antiviral medications in the treatment of Bells palsy.

Nicotine from the mother's blood-stream is passed to the developing fetus. The nicotine affects the developing fetus and can contribute to a wide variety of problems, including low birth weight, birth defects, and sudden infant death syndrome (sids). Another problem caused by smoking is the lowering of blood oxygen content in the mother. When the mother's blood oxygen falls, the fetus also receives less oxygen, a condition called fetal hypoxia. This may contribute to the damaging effects of maternal smoking on the fetus. A doctor examines a child with spina bifida at a clinic near the texas-Mexico border. The child's disorder is believed to have been caused by pollution in the area. Annie griffiths Belt/Corbis, medications and Street Drugs.
Embryo toxins, embryo toxins are any substances that negatively affect or injure the embryo. In general, embryo toxins are called teratogens (tare-at-o-jenz). Teratogens are substances that cause birth defects when the mother is exposed to them. Teratogens may include over-the-counter or prescription medicines, illegal drugs, common household chemicals, industrial waste, alcohol, or tobacco. It is important that the mother avoid teratogens while pregnant, especially during the first twelve weeks of pregnancy when the organs of the embryo and fetus are forming. Pregnant women or those seeking to become pregnant should consult with their physicians about which medications they can and cannot take.
Alcohol, alcohol is a teratogen that should be avoided during pregnancy. Mothers who drink during pregnancy put their child at risk for developing fetal alcohol syndrome (FAS). Fas can result in growth problems as well as mental and other physical congenital defects. Alcohol is a toxin that affects the developing central nervous system of the fetus. Children with fetal alcohol syndrome often show slow physical growth, delayed mental development that can be mild to severe, facial abnormalities, heart defects, and abnormalities of the skeleton. These children usually have mental retardation and frequently have behavior problems and hyperactivity. Tobacco, nicotine from cigarette smoke is another teratogen that should be avoided during pregnancy.

Lower than normal levels of the b vitamin folic acid in the mother may place the developing fetus at risk for anencephaly. stillborn means a baby who is not a live at birth. Spina bifida, spina bifida (spy-na bif-i-da) or myelomeningocele (my-eh-lo-me-ning-oh-seel) is a congenital disorder of neural tube development where there is an opening in the spinal cord and the spinal column (backbone) of the developing fetus. Spina bifida is one of the most common birth defects that involve the nervous system and it may affect as many as 1 in 800 infants. As with anencephaly, deficiency of folic acid in the mother appears to be an important factor in the development of spina bifida. Because the spinal cord is not enclosed in the backbone, the infant has a high risk for meningitis, a serious infection of the spinal fluid, brain, and the lining covering the brain and spinal cord.
Generally the affected person has a loss of body functions below the level of the opening in the. This infant was born with spina bifida. During fetal development, the cells of the neural tube differentiate to form the brain and spinal cord. Spina bifida split spine is a neural tube defect in which the spinal column does not close completely before birth. Custom Medical Stock Photos spinal cord. While surgery at birth will repair the opening, it will not change the loss of function. Children with spina bifida often do not walk unassisted and frequently have learning disabilities. Despite this, many children with spina bifida grow up to live productive lives.

It is important to note that the thomas cause of the majority of birth defects of the central nervous system is unknown or uncertain, that is, no specific genetic abnormality, or toxin, drug, infection, or other environmental factor can be identified. What follows are descriptions of some of the most common types of central nervous system birth defects and some of the agents that may cause them. Anencephaly, anencephaly (an-en-sef-a-lee) is a defect make in the neural tube, which is the part of the developing fetus that forms the spinal cord and brain. During early development, the neural tube fails to close and results in a missing or malformed brain or spinal cord. A fetus with anencephaly is born with no brain or only the very basic parts of the brain that control processes like breathing. Anencephaly is always a fatal condition and the infant may be stillborn * or die within days or weeks of birth. The exact cause of this disorder is still not known. Some studies have suggested that a problem with the nutrition of the mother may be an important cause of this disorder.

How severe the developmental problem that results will be depends on many factors including the type of illness or type or amount of toxin involved. The developing fetus must also receive enough oxygen. Low levels of oxygen reaching the fetus result in what is called intrauterine hypoxia (hy-pox-ee-a). Because cells need oxygen to survive and grow, hypoxia can cause developmental problems in the central nervous system, especially in the early stages of development. Anything that disrupts development at this young age can cause effects that last throughout childhood and adulthood. These types of central nervous system defects are not generally correctable after birth. When the developing brain is exposed to a toxin it is difficult to predict exactly which parts of the brain will be affected or how severely the brain will be damaged. Disorders of intrauterine brain and central nervous system development lead to congenital (con-jen-it-al) disorders or birth defects.
Exposure to disease or toxins * may disrupt the process of development and can result in birth defects and developmental problems in the infant. fetus (fee-tus) in humans, is the unborn offspring in the period after it is an embryo, from 9 weeks after fertilization until birth. embryo (EM-bree-o) in humans, the developing organism from the end of the second week after fertilization to the end of the eighth week, * toxins (tok-sinz) are poisonous substances. Since rapid growth and organ formation occur during the first 12 weeks of development, that is when the embryo and fetus are most susceptible to injury or insult. The aziatische neural (NU-ral) tube, which develops into the spinal cord and the brain, begins to develop about 10 days after conception and continues to develop throughout the pregnancy. Because the mother and the developing fetus are connected, many things that the mother is exposed to or takes into her body can be passed to the fetus. If the mother becomes ill, takes medications, is exposed to toxins, or takes any drugs, the fetus may be affected.

Birth defects of the brain are a group of disorders that result from illness or injury to the brain and central nervous system of a developing fetus. Birth defects can be inherited from a parent or acquired through the mother's contact with environmental factors such as drugs or infections. Birth defects of the brain result in problems that can range from mild to severe. They can affect one part or many parts of the central nervous system.
