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...

bilateral vocal cord paralysis is a rare and preventable complication of anterior cervical discectomy and fusion. herein, we report a fatal case of bilateral vocal cord paralysis after anterior cervical discectomy and fusion (acd/f). a 65-year-old man with cervical spine trauma and anterior cord syndrome, following car overturn presented to our emergency department. the patient had c6-t10 prola...

Resection and simultaneous reconstruction with free flaps of wide tumours of the scalp and posterior neck region are difficult to perform through a single surgical approach. In such cases, the park-bench position - a lateral oblique position - could allow simultaneous resection and reconstruction of tumours of the scalp and occipital region without changing the patient's position. In the case d...

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.
