Web-based medicine as a means to establish centers of surgical excellence in the developing world.

The growth of the Internet has provided a unique opportunity for rapid, global communication. Web-based medicine uses this technology to help surgeons in developing regions of the world gain direct access to recognized experts. This serves to empower local surgeons in the developing world through direct skill-transfer and encouraging academic pursuit. Web-based medicine follows the paradigm of a university without borders, therefore requiring exacting patient record keeping, monthly peer review, and continuing medical education of all its participants. All those who participate in Web-based medicine have undergone a credentialing process to guarantee that they possess adequate credentials. Patient confidentiality is strictly maintained. Web-based medicine also provides a follow-up strategy for medical volunteer groups who provide overseas services. Interplast, Inc., has administered a Web-based medicine site at http://www.wiredmd.com since July of 1999. A total of 767 cleft malformation cases performed locally by participating host surgeons in the developing world have been reviewed through the site. Additionally, 16 consultations have been posted and discussed by participating surgeons worldwide. Financing remains the major impediment to the globalization of this technology.

Establishing cleft malformation surgery in developing nations: a model for the new millennium.

This three-stage model outlines a safe and effective method for achieving a local cleft board in a developing region. Maintaining local culture and guaranteeing patient safety are paramount concerns. Success is rooted in the constant assessment and recognition of negative forces, including misdirection and stagnation. The key factors are the identification of an interested local host and a source of funding as the site evolves toward independence. As of June 30, 2000, 501 cases had been performed independently and free of charge by the host healthcare provider in Nepal. There had been no major morbidities or mortalities.

Simultaneous deep-plane face lift and trichloroacetic acid peel.

Many patients seeking facial rejuvenation require a combination of face lift and chemical peel to achieve optimal results. These procedures traditionally have been separated in time because of fear of skin slough after simultaneous peel and face lift. The recent evolution to deep-plane face lift and peeling agents other than phenol led to this reexamination of the subject. Forty-seven porcine flaps were treated with a variety of chemabrasion agents. As a result, 35% trichloroacetic acid was determined to be a safe agent for use on thick flaps. Thirty-five patients underwent simultaneous modified deep-plane face lift and immediate trichloroacetic acid peel, with 35% being the maximum strength used on undermined areas. This combination proved to be successful, with no complications related to the combination treatment.

Transcoronal blepharoplasty.

Some of the patients requesting blepharoplasty have a combination of excessive eyelid fat and brow ptosis but little or no dermatochalasis. Coronal brow lift, combined with transcoronal fat removal, serves these patients well. The prelevator fat pocket is easily entered from above by incising the periosteum of the anterior orbital roof just inside the orbital rim. Since the orbital septum and anterior lamella of the eyelid rim remain undisturbed, the result appears natural. Contraindications to the procedure include significant medical pocket fat and hair patterns that would exclude a coronal or hairline incision. Two complications, unilateral ptosis and unilateral chemosis, were temporary and totally reversible. Minor changes in the procedure have prevented the recurrence of these problems.

Hypersensitivity dermatitis following suction-assisted lipectomy: a complication of local anesthetic.

We report a case of severe dermatitis involving the abdomen and thighs following suction-assisted lipectomy of these areas wherein local anesthetic containing the preservative methylparaben was used for infiltrative anesthesia. This use of local anesthetics with epinephrine can be of value in the performance of suction-assisted lipectomy to reduce blood loss, serve as an adjunct to other intraoperative anesthetic techniques, and for postoperative analgesia. Local anesthetic solutions commonly contain additives, which serve as antioxidants and antimicrobials. The most common of these preservatives is methylparaben, which can cause delayed hypersensitivity reactions. These reactions may be neither recognized nor clinically significant in small areas of infection, whereas in large body surface infiltrative procedures, such as suction-assisted lipectomy, these reactions may be of considerable consequence. This article reviews the pathophysiology and treatment of these reactions and gives recommendations for avoiding them.

Surgical correction of lesions of the temporomandibular joints.

The previous report of 140 cases of TM joint disorders from the University of Michigan experience has been updated by the addition of 25 recent cases of surgical management of TM joint pathology. The surgical correction pathology of the articular disc, the condyle head, the articular eminence of the glenoid fossa, ankylosis, and chronic dislocation is discussed. Our experiences in these 25 cases are summarized.
