title: Phallic reinnervation via the pudendal nerve.
abstract: Total phallic reconstruction presents the genitourinary reconstructive surgeon with one of the most difficult surgical challenges. The development of microsurgical techniques and free tissue transfers have advanced phallic reconstruction by reducing the number of surgical procedures and by allowing more selectivity in choosing the best innervated donor tissue. During the last 5 years 16 patients underwent total phallic reconstruction using free tissue transfers from distant donor sites. The pudendal nerve was coapted routinely to the major sensory nerves of the donor free flap. The most accurate objective baseline parameters of penile sensibility are pressure and vibratory thresholds, and electrically evoked potentials. We examined 30 normal subjects and 7 patients at least 1 year postoperatively for penile (phallic) sensibility. A pressure aesthesiometer, a biothesiometer and electrodiagnostic studies were used for testing. The 7 postoperative patients (in all of whom the pudendal nerve was incorporated into the reconstruction) had an encouraging return of tactile and erogenous sensibility compared to normal subjects. This is a promising advance in phallic reconstruction.
