The other with hypotelorism (a decreased distance between the eyes), this includes holoprosencephaly (failure of development of the forebrain). In addition, a craniofacial cleft can be classified using the Tessier classification. Each of the clefts is numbered from 0 to 14. The 15 different types of clefts are then subdivided into 4 groups, based on their anatomical position in the face: midline clefts, paramedian clefts, orbital clefts and lateral clefts. FND is a midline cleft, classified as Tessier 0/14. Besides this, the additional anomalies seen in FND can be subdivided by region. None of these anomalies are specific for the syndrome of FND, but they do occur more often in patients with FND than in the population. The anomalies that may be present are:

Nasal: mild anomalies to nostrils that are far apart and a broad nasal root, a notch or cleft of the nose and accessory nasal tags. Ocular: narrowed eye slits, almond shaped eyes, epicanthal folds (extra eyelid tissue), epibulbar dermoids (benign tumors of the eye), upper eyelid colombas (full thickness upper eyelid defects), microphthalmos (one or two small eyes), congenital cataract and degeneration of the eye with retinal detachment. Facial: telecanthus (an increased distance between the corners of the eye), a median cleft of the upper lip and/or palatum, and a V-shaped hairline.
The risk is greater when the mother is small or when the infant is of large weight. Risk of injury to the lower brachial plexus results from traction on an abducted arm, as with an infant being pulled from the birth canal by an extended arm above the head or with someone catching themselves by a branch as they fall from a tree. Lower brachial plexus injuries should be distinguished from upper brachial plexus injuries, which can also result from birth trauma but give a different syndrome of weakness known as Erbs palsy. Other trauma, such as motorcycle accidents, that have similar spinal cord injuries to C8 and T1, also show the same symptoms of Klumpkes paralysis. Diagnosis
Electromyography and nerve conduction velocity testing can help to diagnose the location and severity of the lesion. Otherwise, the diagnosis is one made clinically after a thorough neurologic exam. Treatment
Treatment effectiveness varies depending on the initial severity of the injury. Physiotherapy is used to increase strength of muscle and improve muscle functions. Electrical modalities such as electric nerve stimulation can also be used.Occupational therapy to provide exercises and coping mechanisms to improve the patients ability to perform activities of daily living. Goals of therapy are to improve tactile sensation, proprioception, and range of motion.Acute treatment of a severe injury will involve repositioning and splinting or casting of the extremity. Epidemiology
Klumpke Palsy is listed as a rare disease by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH).
