Neovaginal construction in vaginal aplasia and sex-reassignment surgery.

During the period 1984-1994 33 patients were admitted to the department of plastic surgery for the purpose of neovaginal construction. They comprised 22 patients with vaginal agenesis or aplasia and 11 transsexual men. In most cases neovaginal construction was done by blunt dissection and lining with a split thickness skin graft from the thigh, and in the cases of sex-reassignment surgery genital skin was also used. The two groups differed as the patients with vaginal agenesis or aplasia had remarkably few complications compared with the transsexual group. The most common complications were defects in the skin grafts and vaginal stenosis. The transsexuals therefore had an extended recovery period including several admissions and visits to the outpatient clinic. The difference in genotype does not explain the high complication rate in the transsexual group as eight in the vaginal agenesis or aplasia group had Morris syndrome (testicular feminisation (XY)). However, the phenotype may be of importance in vaginal construction as the male (transsexual) pelvis is narrow and the levator muscles are stronger than those in the female pelvis.
