Nutrition in head and neck cancer patients.

Anorexia and cachexia frequently complicate the late stages of malignancy and can be a prominent feature of early disease. The resulting weight loss significantly affects the morbidity and mortality of the cancer patient. A fundamental understanding of nutrition and the pathophysiology of cancer cachexia will aid in diligent treatment decisions to achieve optimal results.

The venous flap - a safe alternative to the simple vein graft in a special situation.

The use of free tissue transfer has evolved to become the mainstay of treatment of tissue defects. The reconstructive surgeon can choose from a wide variety of flaps. Flaps are chosen based on the tissue defect and also on the characteristics of the pedicle in terms of calibre and vessel length.

A picture speaks a thousand words: the use of digital photography and the Internet as a cost-effective tool in monitoring free flaps.

Microsurgical free tissue transfer is progressing rapidly and is being used more frequently the world over. Monitoring these cases is crucial for a satisfactory outcome. More sophisticated methods are available for monitoring, though they are often expensive.

Radical reduction of lymphedema with preservation of perforators.

Background: Surgical management of lymphedema of the lower extremity is indicated in select patients when conservative measures have failed. The excisional approach has traditionally consisted of a staged excision procedure or total excision of diseased tissue. Based on an improved knowledge of vascular anatomy and understanding of perforator flap surgery, radical reduction of lymphedema with preservation of perforators (RRPP) applies an excisional approach and microsurgical principles to the radical reduction of lymphedema.

Repair of buccal defects with anterolateral thigh flaps.

The ideal reconstructive method for the buccal mucosa should provide durable, stable coverage and a natural contour, while simultaneously minimizing morbidity of both the defect and donor sites. Since the first report of the anterolateral thigh flap in 1984, it has become one of the most commonly used flaps for the reconstruction of various soft-tissue defects. From March 2004-April 2005, 24 free anterolateral thigh flaps were used to reconstruct buccal defects, including the retromolar trigone and as far as the oral commissure, and in some cases with extension to the neighboring palatal region and tongue.
