Current options in head and neck reconstruction.

LEARNING OBJECTIVES: After studying this article, the participant should be able to: 1. Understand current trends in the treatment of head and neck cancer. 2. Discuss the challenges of reconstructing head and neck defects 3. Understand the different reconstructive options available for specific anatomical regions of the head and neck. BACKGROUND: Reconstructive surgery of the head and neck is both technically challenging and rewarding. In the past 20 years, significant advances in this field have improved surgical outcomes and patient function. The development and subsequent refinement of microvascular techniques, in particular, have been a major reason for this progression. METHODS: In this article, the authors review the current options available in head and neck reconstruction. Because a large number of major craniocervicofacial defects result from oncologic resection, the authors have focused their review on this particular subject. By dividing their discussion into different anatomical sites, the authors hope to cover all major aspects of this broad topic. RESULTS: Free tissue transfer has revolutionized head and neck reconstruction. The most widely used free flaps include the fibula, radial forearm, anterolateral thigh, and rectus abdominis. Restoration of both form and function is the ultimate goal. CONCLUSIONS: Although defects of the head and neck region present a challenge, successful cosmetic and functional results have been achieved with both local and free tissue flaps. The flexibility of free tissue transfer, however, has dominated this area and continues to be the method of choice for reconstruction of sizable defects.

Marjolin's ulcer in patients with spinal cord injury.

BACKGROUND: The term "Marjolin's ulcer" is now synonymous with malignant transformation, usually ectodermal and rarely mesenchymal, of chronic ulcers, sinus tracts, and burn scars. DESIGN: Literature search and personal experience with 5 patients during a 30-year period in a spinal cord injury center. FINDINGS: Five cases of Marjolin's ulcer diagnosed among approximately 10,000 patients indicate the rarity of the metaplasia. All cases were fatal. CONCLUSIONS: Chronic pressure ulcers of more than 10 years' duration should be biopsied to rule out malignancy, especially with any change in the nature of the ulcer (eg, exuberant granulation and/or bleeding).

Aesthetic skin branding: a novel form of body art with adverse clinical sequela.

Branding is a form of body art wherein third-degree burns are inflicted on the skin to produce permanent scars. This method of scarification is a common practice among many indigenous cultures and has become exceedingly common in western societies. As with other forms of body art, branding is not a manifestation of a psychiatric disorder but, rather, a method of self-expression. The process can be performed through the use of electrocautery, laser, chemicals, freezing, and hot metal. Complications arising from the procedure include acute infection, transmission of blood-borne pathogens, allergic reactions, and sequelae arising from third-degree burns. In addition, skin branding has been shown to be associated with substance abuse and high-risk behaviors among adolescents. The purpose of this article is to present the following case report and review to familiarize clinicians with this dangerous method of body art.
