SUMMARY This study described a technique for reconstruction of a large lateral thoracic region defect after locally advanced breast cancer resection that allows for full coverage of the defect and primary closure of the flap donor site. The authors performed reconstruction using the newly designed 180-degree rotationally-divided latissimus-dorsi-musculocutaneous flap in a 42-year-old woman for ...

BACKGROUND AND OBJECTIVE Some studies have shown that laser phototherapy is able to increase skin flap viability by decreasing the necrotic area and increasing neoangiogenesis. However, the mechanism by which laser acts on cells is not fully understood. The present study investigated the effects of two different laser wavelengths at 30 and 40 J/cm(2) on the viability of skin flap in rats. MAT...

The early experience of free flap reconstruction in a regional plastic surgery unit was reviewed. Forty-seven free flap surgical procedures were performed for 46 patients during a 2-year period from 1 January 1995 to 31 December 1996 in a regional plastic surgery centre that specialises in head and neck, and breast reconstruction. Twenty-six free transverse rectus abdominus myocutaneous flaps w...

Tumors in cheek and oral commissure are not uncommon free flaps more acceptable solutions for large defects after tumor excision. Flap inset as the last stage of surgery reconstruction has its importance. Aesthetically, flap usually is what patient expects, due to or bizarre shapes. Every deformity this area significant unpleasant. There numerous refinement inset. Authors tried present their mo...

We describe an enzyme-based electroanalysis system for real-time analysis of a clinical microdialysis sampling stream during surgery. Free flap tissue transfer is used widely in reconstructive surgery after resection of tumours or in other situations such as following major trauma. However, there is a risk of flap failure, due to thrombosis in the flap pedicle, leading to tissue ischaemia. Conv...

BACKGROUND This article presents a real-time surgical simulator for teaching three- dimensional local flap concepts. Mass-spring based simulators are interactive, but they compromise accuracy and realism. Accurate finite element approaches have traditionally been too slow to permit development of a real-time simulator. METHODS A new computational formulation of the finite element method has b...

The technology of flap prefabrications is a new, powerful tool in plastic and reconstructive surgery. It is based on an old idea, while applying the latest innovations in surgery. It involves any modification of a surgical flap done before its transfer to the final donor site, including surgical delay, pre-expansion, pre-grafting, the use of tissue engineering, biomaterials and perforators surg...

Accurate and early prediction of tissue viability is the most significant determinant of tissue flap survival in reconstructive surgery. Perturbation in tissue water content (TWC) is a generic component of the tissue response to such surgeries, and, therefore, may be an important diagnostic target for assessing the extent of flap viability in vivo. We have previously shown that reflective terah...

BACKGROUND Latissimus dorsi flap is one of the best options for immediate and delayed breast reconstruction. However, this technique is limited by the tissue volume provided by the flap. To improve breast volume while reducing complications, fat grafting is now very often used in addition to latissimus dorsi flap. To the best of our knowledge, fat grafting was always performed as a second-line ...

In free-flap surgery, if the appropriate length of the pedicle and the distance necessary for separation of the artery and vein are determined earlier during flap elevation, the operative time and the stress placed on the flap pedicle can be reduced. However, the pedicle of a flap passes through 3-dimensional structures, particularly in head and neck reconstructions, and because of the differen...
