Another approach is the use of an autotransplant of a resected sigmoid colon using laparoscopic surgery; results are reported to be very good with the transplant becoming a functional vagina.Uterine transplantation has been performed in a number of people with MRKH, but the surgery is still in the experimental stage. Since ovaries are present, people with this condition can have genetic children through IVF with embryo transfer to a gestational carrier. Some also choose to adopt. In October 2014, it was reported that a month earlier a 36-year-old Swedish woman became the first woman with a transplanted uterus to give birth to a healthy baby. She was born without a uterus, but had functioning ovaries. She and the father went through IVF to produce 11 embryos, which were then frozen. Doctors at the University of Gothenburg then performed the uterus transplant, the donor being a 61-year-old family friend. One of the frozen embryos was implanted a year after the transplant, and the baby boy was born prematurely at 31 weeks after the mother developed pre-eclampsia.Promising research include the use of laboratory-grown structures, which are less subject to the complications of non-vaginal tissue, and may be grown using the womans own cells as a culture source. The recent development of engineered vaginas using the patients own cells has resulted in fully functioning vaginas capable of menstruation and orgasm in a number of patients showing promise of fully correcting this condition. Epidemiology
The prevalence remains sparsely investigated.
The endoscope allows minimally invasive  access through the natural ear canal, rather than through the usual 5 cm incision behind the ear utilized in traditional microscopic surgery. The 30 degrees endoscope allows access to the bony area of the Eustachian tube to address any obstructive pathologies. Prognosis
It is important that the patient attend periodic follow-up checks, because even after careful microscopic surgical removal, cholesteatomas may recur. Such recurrence may arise many years, or even decades, after treatment. A residual cholesteatoma may develop if the initial surgery failed to completely remove the original; residual cholesteatomas typically become evident within the first few years after the initial surgery. A recurrent cholesteatoma is a new cholesteatoma that develops when the underlying causes of the initial cholesteatoma are still present. Such causes can include, for example, poor Eustachian tube function, which results in retraction of the ear drum, and failure of the normal outward migration of skin.In a retrospective study of 345 patients with middle ear cholesteatoma operated on by the same surgeon, the overall 5-year recurrence rate was 11.8%. In a different study with a mean follow-up period of 7.3 years, the recurrence rate was 12.3%, with the recurrence rate being higher in children than in adults. The use of the endoscope as an ancillary instrument has been shown to reduce the incidence of residual cholesteatoma.
