The umbilicus is perhaps the only scar that all of us want. The umbilicus forms after birth as a result of the placental cord being transected as the infant is “detached” from his/her mother. As the stump of the cord necroses, the scab falls away as the base heals leaving a scar: the umbilicus.
The umbilicus has been described as a depressed scar surrounded by a natural skin fold that measures 1.5 to 2 cm in diameter and lies anatomically within the midline at the level of superior iliac crest.
Neoumbilicoplasty in simple terms is the creation or reconstruction of a new umbilicus to replace the missing or deformed umbilicus. (absence of defined umbilicus, photo credit)
Those characteristics found to be unappealing include a large overall umbilical size, a horizontal or distorted shape, and the presence of umbilical protrusion.
In reconstructing the umbilicus, plastic surgeons should strive to attain these attractive characteristics and incorporate a modest size, with a superior shelf or hood and a T or vertical shape.
Reconstruction of a new umbilicus is indicated in congenital conditions associated with umbilical agenesis, loss of umbilicus due to omphalocele or gastroschisis repair, umbilical loss due to inflammatory destruction, excision of skin cancer involving the umbilical stump, and in surgical procedures for wide ventral herniorrhaphy.
In my humble opinion, the site of the new umbilicus should correspond to where “nature” would have placed it. If there is any of the old umbilicus present, this can be used as an indication of where the new umbilicus should be placed. If not, then Dr. Susam Park, et al has this suggestion:
Based on our study, it is usually 3 cm above the level of the anterior superior iliac spine in a baby and 6 cm above in an adult, although differences in height and weight may affect these measurements.
Or as Dr. Suhas Abhyankar, et al put it:
1. The distance between the xyph0sternum and umbilicus-distance between the umbilicus and the pubic symphysis ratio is approximately 1.6:1.
2. Also, the distance between the umbilicus and the anterior superior iliac spine-distance between the right and left anterior superior iliac spines ratio is 0.6:1. This implies that when each of the anterior superior iliac spines is taken as a center, and arcs are drawn with a radius 0.6 times that of the inter-anterior superior iliac spine distance, the point of intersection of these arcs is the location of the umbilicus, taking into consideration the above ratio (1.6:1).
Surgery varies depending on whether a completely new umbilicus is being created or simply an “outie” being turned into an “innie” or maintaining the umbilicus with other surgery (ie abdominoplasty).
