The dorsal penile nerve cut is a 0.5 – 2 cm nerve cut (most hospitals do this now). Repairing this nerve is not difficult for orthopedic and hand surgeons; it is as easy as repairing the finger nerve in a broken finger replant. If there is a defect after removal of a segment of the nerve a nerve graft must be done, both commonly used to repair the peroneal nerve. This donor area was used 70 years ago and there are no functional problems, only numbness in a small area outside the dorsum of the foot. I specialize in genitourinary plastic and microsurgery and penile reconstructive surgery, and I have no problem with repairing this nerve. During the surgery, the two severed nerves were released and the length in between was the length of the defect after natural retraction. There is no need to excessively lengthen the length of the cut nerve, as the result is the same as if it were not excessively lengthened. Generally, the cut nerve has a natural retraction of 20-30%, so the natural length without tension is sufficient, including the reserved length. However, deep fascial reduction must also be done during surgery to prevent erection from pulling the nerve anastomosis. Sexual intercourse is usually possible after 6 weeks after surgery, and oral nerve-nourishing drugs can be taken after January. The commonly used drugs are Micronutrients and vitamin B1, which are usually taken for 3 months. One to three weeks after surgery, 30-45% of patients feel that there is a return of sensation in the glans immediately after the repair, and this phenomenon is very common in finger replantation. This is mainly due to the fact that the transplanted nerve is still active and has sensory conduction function. This phenomenon disappears immediately afterwards and gradually returns to glans sensation until 6-14 months after surgery. During this long period of time there is a little change that the patient may find difficult to appreciate. If part of the small nerve is cut, the numbness is not very contrasting and there is a little recovery that he may not appreciate. However, some people think that the repair is ineffective, which is a prejudice. On the contrary, if the nerve trunk is cut and repaired, there is a big difference in the recovery sensation, and the patient can easily experience the change. Regarding the timing of surgical repair, I think the earlier the better. In one patient who came for repair 6 days after the cut, there was no change in the severed end of the cut nerve, so the repair was easy and the recovery was fast and the result was good. The later the repair time is, the more the distal end of the cut nerve atrophies, which is detrimental to the repair, slow recovery, poor results, and low recovery percentage. The nerve graft has two nerve anastomoses and the nerve grows slowly, so it takes 3-6 months to cross one anastomosis, so it takes a long time to wait after repair. If the nerve can be directly anastomosed this is the best result, but the previous surgery was to remove a section of the nerve that could not be directly anastomosed to the end, and even if it was, it would definitely break during erection.
