BACKGROUND Posttraumatic, high-energy defects of the midface can be challenging to reconstruct because they involve extensive composite tissue loss and result in significant permanent functional and cosmetic deformity. These injuries require replacement of the bony framework, external soft tissue, and intraoral mucosa. Local skin flaps and nonvascularized bone grafts have been used for reconstr...

A popular strategy in the treatment of articular cartilage lesions involves the introduction of cell suspensions into the defect void and its closure with a periosteal flap (autologous chondrocyte transplantation technique). We applied this methodology in goats and discovered that all sutured flaps (n = 6 animals) became detached from nonimmobilized joints during the recovery period. The purpos...

PURPOSE This article reviews a few of the commonly used types of vascularized osseous free flaps in maxillofacial reconstruction, which still represents the gold standard of restoration. We also discuss the developing concepts in maxillofacial reconstruction. RECENT FINDINGS Most of the literature reconfirms the established patterns of reconstruction with the aid of vascularized osseous free ...

This article reports our experiences treating soft tissue and bone defects in the lower extremity with free flaps. One of the most common causes for lower extremity wounds are high-energy injuries. These kinds of injuries contain soft tissue and bone defects beyond neurovascular complications. The rate of infection and nonunion is very high in these injuries. Between 1988 and 1996, we applied 3...

For the successful reconstruction of facial defects, various perforator flaps have been used in single-stage surgery, where tissues are moved to adjacent defect sites. Our group successfully performed perforator flap surgery on 17 patients with small to moderate facial defects that affected the functional and aesthetic features of their faces. Of four complicated cases, three developed venous c...

Buffered crossbar switches are special crossbar switches with each crosspoint equipped with a small exclusive buffer. The crosspoint buffers decouple input ports and output ports, and simplify switch scheduling. In this paper, we propose a scheduling algorithm called Fair and Localized Asynchronous Packet Scheduling (FLAPS) for buffered crossbar switches, to provide tight performance guarantees...

PURPOSE To report serious complications caused by recutting laser in situ keratomileusis (LASIK) flaps for enhancement and reconsider the current preferred method of LASIK enhancement. SETTING Multiple surgeon practices. METHODS This retrospective noncomparative nonconsecutive case series comprised LASIK patients in the private practices of 9 experienced refractive surgeons and those report...

background current teaching suggests increased perfusion in free transverse rectus abdominis myocutaneous (tram) flaps over pedicled tram flaps, broadening indications for its use in high risk patients. this study compared perfusion analysis of free muscle-sparing versus pedicle tram flaps in vivo in the peri-operative and late post-operative periods. methods the spy-elite system using indocyan...

The first terminology consensus on perforator flaps, reached in 2001, was reviewed and further simplified following the Sixth International Course on Perforator Flaps.

Introduction: The pericranial flaps' benefits have been described in many otolaryngologic, maxillofacial and plastic surgery literature. The benefits ar e due to the pericranial flaps unique characteristics including good flexibility and mobility, very rich blood supply from several arterial sources and access to sufficient bulk of the flap without any need for distant surgical sites. Using pe...
