A modified approach for feminizing genitoplasty.

PURPOSE: We reported the use of the mucosal layer of preputial skin to give extra length to penile flaps on vaginal introitus and labia minora reconstruction in children with congenital adrenal hyperplasia.

MATERIALS AND

METHODS

Since November 1999, 14 patients (average age 16 months, range 6 months-4 years) have undergone early one-stage reconstruction of external genitalia. All patients were classified according to Prader's classification (from III to V degree) with clitoral size of 3 +/- 1.5 cm. The perineal sagittal approach is followed by careful dissection and partial mobilisation of the urogenital sinus. Subcutaneous reduction clitoroplasty has been performed. The mucosal layer of the prepuce, developed as an extended flap on the end of the phallic shaft skin used for labia minora, is ideally placed for reconstruction of the vestibulae and distal vagina.

RESULTS

The vagina was calibrated, the main vaginal calibre was 10 Hegar (range 6-14). With one exception, the urethral meatus was situated in the vestibulae and easily accessible. One distal vaginal stenosis was observed in a case with high confluence. No urinary incontinence was noted. The appearance of external genitalia was very satisfactory.

CONCLUSIONS

The described genitoplasty provides a good cosmetic appearance. As most of our patients have not yet reached the age of sexual activity and child bearing, the functional results of this operation will need longer-term evaluation.
