Microscope-assisted Reduction Clitoroplasty Used to Treat Two Patients with Clitoromegaly

抄録

We report 2 cases of clitoromegaly, 1 in a patient with true hermaphroditism, and the other in a patient with adrenogenital syndrome. Both were treated surgically with reduction clitoroplasty. There are 3 different clitoroplasty procedures: clitorectomy, clitoral recession, and reduction clitoroplasty. Reduction clitoroplasty with preservation of the neurovascular bundle is considered superior in terms of formation of the external genitals and sensation. However, the disadvantages are that detachment of the neurovascular bundle from the clitoral shaft is difficult and that there is a high possibility of sensory and blood flow disorders in the clitoris. In an attempt to achieve safe and reliable surgical manipulation, we used a surgical microscope (OPMI 6-SDFC, Carl Zeiss Surgical GmbH, magnification ×8) to detach the neurovascular bundle from the clitoral shaft in our 2 patients. Our impression is that our efforts were extremely effective. Furthermore, our experience leads us to believe that the procedure for neurovascular bundle detachment required in reduction clitoroplasty is not particularly difficult if performed with a surgical microscope by a plastic surgeon who regularly performs microsurgery. Because the procedure can be performed simply and safely, we believe that reduction clitoroplasty with preservation of the neurovascular bundle is the best overall of the 3 clitoroplasty procedures.
