Combined urinary and fecal incontinence is sometimes termed double incontinence, and it is more likely to be present in those with urinary incontinence.Traditionally, FI was thought to be an insignificant complication of surgery, but it is now known that a variety of different procedures are associated with this possible complication, and sometimes at high levels. Examples are midline internal sphincterotomy (8% risk), lateral internal sphincterotomy, fistulectomy, fistulotomy (18-52%), hemorrhoidectomy (33%), ileo-anal reservoir reconstruction, lower anterior resection, total abdominal colectomy, ureterosigmoidostomy, and anal dilation (Lords procedure, 0-50%). Some authors consider obstetric trauma to be the most common cause. History
While the first mention of urinary incontinence occurs in 1500 BC in the Ebers Papyrus, the first mention of FI in a medical context is unknown. For many centuries, colonic irrigation was the only treatment available. Stoma creation was described in 1776, FI associated with rectal prolapse in 1873 and anterior sphincter repair in 1875. During the mid 20th Century, several operations were developed for instances where the sphincters were intact but weakened. Muscle transpositions using the gluteus maximus or the gracilis were devised, but did not become used widely until later. End-to-end sphincteroplasty is shown to have a high failure rate in 1940. In 1971, Parks and McPartlin first describe an overlapping sphincteroplasty procedure. Biofeedback is first introduced in 1974. In 1975, Parks describes post anal repair, a technique to reinforce the pelvic floor and EAS to treat idiopathic cases.
Hemifacial hypertrophy (also termed facial hemihypertrophy, facial hemihyperplasia, or Friedreichs disease) abbreviated as  (HFH) is rare congenital disease characterized by unilateral enlargement of the head and teeth. It is classified as true HFH (THFH) with unilateral enlargement of the viscerocranium, and partial HFH (PHFH) in which not all structures are enlarged. Hemifacial hypertrophy can cause a wide spectrum of defects or may involve only muscle or bone. it is usually treated surgically. It is believed to be a minor form of hemihypertrophy. References
