This study has provided baseline data of a quantitative neurophysiological appraisal of normal breast sensibility using our current understanding of cutaneous mechanoreceptive function. Test variables, including pressure, low- and high-frequency vibration, static and moving two-point discrimination, temperature, nipple erectibility, and pain, were evaluated(More)
1. A total of 758 fibers were isolated from previously transected and repaired ulnar nerves of five baboons. These fibers were compared to fibers from normal and previously crushed nerves studied in an earlier experiment. 2. The conduction velocities of the proximal portion of the injured axons dropped below normal, and this reduction persisted until(More)
This report proposes that reflex sympathetic dystrophy be defined as a pain syndrome in which the pain is accompanied by loss of function and evidence of autonomic dysfunction. In the clinical setting, this diagnosis is usually associated with other anatomic and psychological diagnoses and may be associated with a variety of systemic illnesses and(More)
Fatty tumors of the peripheral nerves, although rare, occur with sufficient frequency to pose problems in diagnosis and treatment. Moreover, the nomenclature of these tumors has suffered from controversy over their morpological description. These factors have contributed to a misunderstanding about the treatment of these localized nerve abnormalities(More)
Thus far, devastating injuries of the adult brachial plexus have had a poor prognosis. This article presents the possible outcomes of aggressive microsurgical reconstruction in the largest series of patients in North America to date. It should change the pessimistic outlook that has surrounded these lesions. In this study, the outcomes of surgery were(More)
Single fibres were dissected from the dorsal spinal roots of the nerves serving the brachial plexus in African green monkeys. The dermatomal organization of these spinal nerves was deduced from data concerning the receptive fields of 2834 single afferent fibres. These data were collected in an attempt to reconcile some of the discrepancies that exist in(More)
Over the past four years we have performed total phallic reconstructions in 12 patients. Six patients underwent reconstruction following trauma, 3 were female-to-male transsexuals, and 3 had micropenis deformities. These reconstructions were one-stage microsurgical tissue transfers that included urethral reconstruction and coaptation of erogenous nerves.(More)
Nerve grafting has made advances in the last 100 years. One of the most significant of these was realizing the importance of adequate blood supply for successful nerve grafting. The vascular anatomy of the six potential vascularized donor nerves we have reviewed may prove to be extremely useful in reconstructing proximal nerve lesions, large nerve defects,(More)
This study investigated axonal regeneration in a denervated nerve graft sutured end-to-side with a main peripheral nerve trunk. To demonstrate morphologic changes, the peroneal nerve was severed in a rat and coapted end-to-side to the posterior tibial nerve. The integrity of the epineurial and perineurial sheath was altered in four different groups.(More)
The facial paralysis patient suffers serious functional, cosmetic, and psychological problems with impaired ability to communicate. Despite the advances of recent years and the number of new techniques proposed in the literature, facial reanimation remains a challenge for the reconstructive surgeon. With the advent of microsurgery, reanimation of the(More)
