Construction of neoglans penis: a new sculpturing technique from rectus abdominis myofascial flap.

INTRODUCTION

Construction of a neoglans penis may be required following glans amputation at circumcision, strangulation by a hair coil, or self-mutilation, among other indications. It may also be combined with phalloplasty to imitate the natural appearance and to support a penile prosthesis.

AIM

This is a report on a novel technique of neoglans construction for a patient with an amputated glans penis as a result of circumcision injury.

METHODS

A rectus abdominis myofascial flap was used. The flap was designed to be a 12 x 4 cm segment of the infraumbilical portion of the muscle, based on the inferior epigastric vessels. The flap was harvested through a paramedian incision. The penis was partially degloved through a circumferential incision 1 cm below its summit. The distal penile skin was utilized to elongate the urethra, so that the urethral meatus would be at the tip of the neoglans. The flap was reflected and tunneled underneath the mons veneris and alongside the penis, to emerge distal to the summit of the penis. The flap was fashioned into the shape of a glans and secured in place around the neourethra. The impression of a corona was achieved by tucking the proximal edge of the flap to its undersurface.

RESULT

Six months following surgery, the patient had a neoglans penis, a corona, and a urethral meatus at the very tip. The neoglans had similar consistency, color, and shape to the normal glans.

CONCLUSION

Construction of a neoglans penis is possible using the described sculpturing techniques, with satisfactory cosmetic results.
