OBJECTIVE To evaluate the dynamic change of CD34 level during the survival process of narrow pedicle flaps. METHODS Twenty-five white pigs were randomly and equally divided into 5 experimental groups. Five different type of narrow pedicle with different length-to-width ratio were employed, and each type of narrow pedicle was covered with 5 different size random flaps and which was classified ...

BACKGROUND There is a paucity of reports in the literature examining the pattern of sensory and autonomic neural recovery of myocutaneous microvascular flaps and skin grafts to the lower limbs after a prolonged period of time. OBJECTIVES To investigate the recovery of sensation and autonomic nerve activity in long-standing split-skin grafts applied to fascial beds and in myocutaneous microvas...

The fingertip skin defect is a common hand injury often accompanied by tendon or bone exposure, and is normally treated with flaps. The aim of this study was to evaluate the functional sensory recovery of random-pattern abdominal skin flap in the repair of fingertip cutaneous deficiency. A total of 23 patients, aged between 18 and 50 years (mean age, 31 years) with fingertip cutaneous deficienc...

Venous flaps are defined as a composite flap of skin and subcutaneous veins that relies on the venous system alone for flap perfusion, that is, the primary blood supply enters and exits the flap through the venous system. [1] Unlike conventional arterial flaps, venous flaps do not sacrifice an artery of the donor site nor do they require deep dissection. This results in an easier procedure as w...

Local skin flaps have revolutionized reconstructive surgery. Mechanical loading is critical for flap survival: Excessive tissue tension reduces blood supply and induces tissue necrosis. However, skin flaps have never been analyzed mechanically. Here we explore the stress profiles of two common flap designs, direct advancement flaps and double back-cut flaps. Our simulations predict a direct cor...

Total ear reconstruction in the postburn auricle is one of the most challenging procedures for plastic surgeons. Adverse factors associated with these procedures include reduced or damaged blood supply, poor elasticity of scar tissue, increased risk of infection, and the possible destruction of skin, temporoparietal fascia, or retroauricular fascia. In cases where patients are severely burned, ...

Reconstruction of the lower limb presents a complex problem after skin cancer surgery, as proximity of skin and bone present vascular and technical challenges. Studies on vascular anatomy have confirmed that the vascular plane on the lower limb lies deep to the deep fascia. Yet, many flaps are routinely raised superficial to this plane and therefore flap failure rates in the lower limb are high...

background lesions in perineal area are common. the usual treatment is coverage by skin graft and flaps which may be local, pedicled or free types. in this paper v-y flaps were used to cover the defects. methods v-y flaps were used in the gluteal area in 15 patients. lesions were due to different causes. results of 15 patients, 11 were males and 4 were females. their ages ranged from 3 weeks to...

The use of degradable polymeric implant materials for defect closure after tumor surgical resection in the area upper aerodigestive tract instead skin muscle flaps would represent a novel therapeutical option oncological head and neck surgery. Successful coverage with not only reduce morbidity but also improve swallowing speech function comparison to flaps.
