Urethra reconstruction following resection of penile leiomyosarcoma.

Leiomyosarcoma is a rare tumor, particularly in genital area. We present a case of penile lyomyosarcoma. Surgical treatment involved subcutaneous penectomy, preserving a sensate skin envelope, bilateral groin dissection and perineal urethrostomy. Reconstruction of the urethra and soft tissue was carried out using a free radial forearm flap. We believe that subcutaneous penectomy should be considered as a treatment option in selected cases of penile tumor as this facilitates urethral reconstruction.

The compound dorsal metacarpal artery tendofasciocutaneous flap: an attractive reconstructive tool for complex digital defects.

Different modifications of flaps based on the dorsal metacarpal arterial system have been reported as reliable tools for reconstruction of dorsal and palmar phalangeal soft tissue defects. For simultaneous reconstruction of the extensor aponeurosis and joint in complex injuries of the dorsal index, we used a distally based pedicled fasciotendocutaneus second dorsal metacarpal flap, including the complete vascularized extensor indicis tendon in 2 cases. Clinical results of this procedure have not been reported so far.

Does a superficial musculoaponeurotic system exist in the face and neck? An anatomical study by the tissue plastination technique.

An exact knowledge of the subcutaneous layers in the different regions of the face and neck is important in several surgical disciplines. In the parotid region, a superficial musculoaponeurotic system (SMAS) has been described. The existence of a SMAS as a guiding structure for the surgeon in the other regions of the face and neck has been discussed but is controversial. Therefore, the authors investigated the development of the subcutaneous connective-tissue layers in the different facial regions and in the neck. They studied these regions in 22 human fetuses using the technique of plastination histology and in three newborn and three adult specimens using sheet plastination. In addition, they dissected the neck and face in 10 fresh adult cadavers to identify the SMAS as in the surgical situation. The results show that no SMAS could be detected in any facial regions other than the parotid region. In the parotid region, it is thick and attached to the parotid sheath. However, it becomes very thin, discontinuous, and undissectable in the cheek area. No SMAS can be found in the neck, in which the authors are the first to describe a fascia covering both sides of the platysma. This fascia has close topographical connections to the subcutaneous layers of the adjoining regions. On the basis of these findings, the surgical pathways have to be defined regionally in the face. A "platysma fascia" can be considered as a surgical landmark in the neck. Therefore, the authors conclude that it is not justified to generalize a SMAS as a surgical guiding structure.

Receptors for NGF and GDNF are highly expressed in human peripheral nerve neuroma.

Immunhistochemistry of 10 traumatic human peripheral nerve neuromas and 5 normal digital nerves revealed a high immunoreactivity for the nerve growth factor (NGF) receptors p75 and trkA and the glial cell line-derived neurotrophic factor (GDNF) receptor GFRalpha-1. Semiquantitative image analysis showed a significantly increased trkA immunoreactivity in the neuroma group. The presence of the receptors may provide a way to influence therapy of peripheral nerve neuroma by administration of neurotrophins or other substances with binding sites similar to those of a neurotrophic factor.

Plastic surgeons and the Internet: results of a worldwide survey.

To obtain information on the use of the Internet, 3,139 survey forms were sent out to plastic surgeons throughout the world. More than 90% of the 565 respondents have access to the Internet and 85.5% use electronic mail for professional matters. They use the World Wide Web to search the literature, to read scientific articles, and to obtain information on congresses. A substantial proportion of the contributors have a positive attitude toward virtual congresses on the Internet and most would welcome a newsgroup dedicated to plastic surgery. Perceived apprehensions include secure transmission of sensitive data, slow data transmission, and the lack of structure and of an authority to control the contents of the Internet. Virtual congresses and a newsgroup on plastic surgery seem to be worthwhile future goals. Some problems pointed out in this survey have already been solved, at least partially, and possible solutions for the rest are discussed.
