BACKGROUND Locoregional flaps are sufficient in most sacral reconstructions. However, large sacral defects due to malignancy necessitate a different reconstructive approach, with local flaps compromised by radiation and regional flaps inadequate for broad surface areas or substantial volume obliteration. In this report, we present our experience using free muscle transfer for volumetric reconst...

BACKGROUND The purpose of this study was to determine the causes of head and neck free flap loss and to evaluate outcomes after subsequent microvascular and non-microvascular reconstruction. METHODS Patients who experienced free flap loss between 2000 and 2012 were reviewed. RESULTS There were 40 flap losses out of 3090 free flaps (1.3%). Twenty-eight patients underwent subsequent free flap...

approached with care, and either neovascularization across the flap should be confirmed or the main vascular pedicle should be left intact. We report a case of the total loss of a flap after a secondary operation was performed 18 months after successful reconstruction using a latissimus dorsi muscle flap. There is controversy concerning flap neovascularization, and many factors can compromise f...

PURPOSE To determine how refractive error, visual acuity, and high-order aberrations (3rd- and 4th-order) are affected by the formation of a lamellar corneal flap during laser in situ keratomileusis (LASIK). SETTING University refractive surgery center. METHODS The effect of lamellar corneal flap formation was analyzed in 15 myopic eyes (mean preoperative refraction -4.72 diopters [D] [rang...

background although the assignment and suturing of the spreader graft to the septum is a routine part of rhinoplasty, it is a time wasting procedure and some problems may occur. rather, autospreader flap is a new method that the dorsal part of the upper lateral cartilage is used as its own graft. in the present study, we intended to compare the functional and aesthetic outcomes of these two tec...

Dna2 is a nuclease/helicase with proposed roles in DNA replication, double-strand break repair and telomere maintenance. For each role Dna2 is proposed to process DNA substrates with a 5'-flap. To date, however, Dna2 has not revealed a preference for binding or cleavage of flaps over single-stranded DNA. Using DNA binding competition assays we found that Dna2 has substrate structure specificity...

results: we performed reverse sural flaps in eight gunshot patients, to cover the defects of the lower leg and foot. surgical site infection observed in one patient (12.5%) was treated successfully with antibiotic therapy. the reverse sural flap provided a satisfactory coverage for gunshot defects in all the patients. objectives: the purpose of this prospective case series study was explore the...

introduction: reconstruction of the oral cavity witha flap design containing the buccal mucosa and buccinator muscle but excluding the facial artery and vein is the topic of these case reports. case reports: this article uses random pattern vertically oriented partial thickness buccinator myomucosal flap for intraoral reconstruction in two cases. the first was for lining the mandibular anterior...

The proposed reduction in and recent negotiations, discussions and lobbying concerning the R&D budget of the Office of the Chief Scientist (OCS) at the Ministry of Industry and Trade highlight the importance of approaching the question of government policy in support of R&D not only in a more systematic and analytic fashion than has been the case up to now in Israel but also through adoption of...

An original equipment manufacturer (OEM) produces new products and often faces a dilemma when determining the level of interchangeability in its product design. The interchangeability is considered as a degree to which the product can be disassembled without force, and thus an increasing degree of interchangeability would decrease the OEM’s production cost, but it would also lower a remanufactu...
