Purpose:
Enlargement of the clitoris is often a prominent manifestation of virilizing congenital adrenal hyperplasia and other disorders of sexual development. Controversy persists regarding the viability and sensitivity of the clitoris following clitoroplasty. We present 51 consecutive cases of nerve sparing ventral clitoroplasty performed by a single surgeon.
Materials And Methods:
Nerve sparing ventral clitoroplasty was performed in all patients. Postoperative evaluation for clitoral viability included gross examination and capillary perfusion testing. Patients older than 5 years were evaluated for clitoral sensory testing and vibratory sensory testing.
Results:
A total of 51 patients 4 months to 24 years old (mean age +/- SD 4.6 +/- 6.8 years) with clitorimegaly underwent nerve sparing ventral clitoroplasty. Of the patients 41 had capillary perfusion testing of the clitoris, of whom all had a viable clitoris. Ten of the 41 patients underwent clitoral sensory testing. Patients reported an average degree of sensation of 3.6 +/- 0.9 at the labia minora and 4.8 +/- 0.4 at the clitoris. Nine of the 10 patients also underwent vibratory sensory testing. Average values for the introitus, clitoris, labia and thigh were 3.56, 1.61, 5.08, and 5.83, respectively. Mean time after surgery for the patients who underwent clitoral sensory testing/vibratory sensory testing was 2.0 +/- 0.8 years. No variations in the sensitivity results were reported at followup in 2 patients.
Conclusions:
To our knowledge this is the largest report of followup testing of clitoral viability and sensation after clitoroplasty. Continued long-term followup is ongoing to document long-term sexual function using this nerve sparing ventral approach for clitoroplasty.
