Abstract
|
|
|
The most common etiology for remale pseudohermaphroditism is congenital addrenal hyperplasia, which asccounts for more than 60 percent of children with ambiguous genitalia, and is treated with cortisol replacement and surgical correction of
ambiguous
genitalia. Flap vaginoplasty, the inverted U-Shaped type has been applied worldwide to the patient with low vaginal entry. Thr most frequnt complication of the operation is contraction of the new vaginal introitus asd a result of ischemic and
fibrotic
changes in the overlapping surture line between the flap and posterior vaginal wall. Maintenance of a gold blood supply for the flap and tension free anastomosis should always be kept in mind to avoid this complication.
We experienced a vaginoplasty with labioscrotal flap instead of the inverted U-shaped flap and achieved a good result in a 14-year-old girl with low vaginal entry due to congenital adrenal hyperplasia. The labioscrotal flap seems to be more
suitable
than inverted U-shaped flap for vatginoplasty because the labioscrotal skin is more elastic and more easily elongated than the perineal skin.
