ABSTRACT: Free flaps have become a popular option for the reconstruction of intraoral defects. The radial forearm flap used to be the workhorse flap for small and thin defects, but was associated with numerous donor-site morbidities. The proximal lateral leg flap can provide a thin and pliable tissue similar to the radial forearm flap but without the related donor-site morbidities. We compared the differences between these 2 flaps. Thirty-four patients with intraoral defects from September 2005 to October 2011 were reconstructed, using the radial forearm flap in 23 cases, and the proximal lateral leg flap in 11 cases. The radial forearm flap group had a success rate of 95.6%. The flap survival rate was 100% in the proximal lateral leg flap group. However, the difference was statistically insignificant. Skin graft was required in 22 of the 23 cases for the donor site of the radial forearm flap. Partial loss of the skin graft occurred in 5/22 (23%) of the patients, with exposure of tendons in 3/22 (14%). Delay in healing of the donor sites occurred in 6/23 (26%) of the patients. The donor sites of the proximal lateral leg flap were all closed primarily. One case developed wound dehiscence and this healed by conservative treatment. Long-term follow-up showed functional impairment of the donor forearm (reduced extension or grip strength) in 17% of the patients. Thirty percent of the patients developed sensory disturbance and 48% complained of poor outcome of the donor forearms. In the proximal lateral leg flap group, no motor or sensory functional deficits were seen. No patients complained of poor outcome of the donor legs. Primary closure of the donor site of the proximal lateral leg flap could be performed if the flap width was less than 6 cm. This flap is useful for patients with small and thin intraoral defects and is associated with minimal donor-site morbidity when compared to the radial forearm flap.

Combined bypass surgery with free flap reconstruction is an established method for lower limb salvage. But the success of the combination of endovascular revascularization together with free tissue transfer has so far not been well established. A retrospective review of all patients who had undergone endovascular revascularization and reconstructed with free tissue transfer for lower limb salvage at Tzu Chi Dalin General Hospital between 2008 and 2012 was performed. A total of 26 legs underwent limb salvage in 24 patients. There were 10 male and 14 female patients. Their average age was 71.4 years. The average time interval between endovascular intervention and free tissue transfer was 8 days. There was 100% flap survival but partial flap necrosis was seen in three patients. A high rate of wound infection was seen in eight patients, all requiring further debridement. The total limb salvage rate at 1-year follow-up was 96% and 92% at the 2-year follow-up. In conclusion, the success rate of lower limb salvage using a combination of endovascular revascularization and free tissue reconstruction is comparable to using a combination of bypass surgery and free tissue transfer. It is associated with a high flap success rate and a high limb salvage rate. It provides physicians with a further treatment option in the management of ischemic lower limbs with extended tissue loss. © 2014 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Background Extensive defects of the lower limb as a result of diabetes and peripheral vascular disease require multidisciplinary treatment. Numerous studies with regards combining vascular bypass surgery and free tissue reconstruction of the lower limb had been published. However the trend has evolved toward a combination of endovascular revascularization and free flap reconstruction. The aim of this study was to compare the safety and efficacy of this combination of treatment to the traditional combination of bypass surgery and free tissue reconstruction. Methods All patients who had undergone vascular bypass surgery and free tissue reconstruction of the lower limb as well as those who had undergone endovascular angioplasty with free tissue transfer for lower limb preservation, over a 10-year period was included in this study. Results A total of 46 patients that underwent limb preservation were included in this study, 22 patients underwent open bypass revascularization and free flap transfer and 24 patients underwent endovascular revascularization and free tissue transfer. There were no differences between the two methods with regards to age, sex, defect size, TransAtlantic InterSociety Consensus level, Wagner classification, length of hospitalization, limb preservation rate, total flap necrosis rate, and partial flap necrosis rate. More importantly, there was no significant difference in the limb preservation rate (P = 0.14). Conclusion In this study we found that the safety and the success rate of lower limb preservation using a combination of endovascular revascularization and free tissue reconstruction is comparable to using a combination of bypass surgery and free tissue transfer. © 2015 Wiley Periodicals, Inc.
