OBJECTIVE:  Musculocutaneous flap reconstruction surgery is one of the standard procedures following head and neck cancer resection. However, no previous studies have classified flaps in terms of muscle and fat or examined them after long-term follow-up. The purpose of this study was to estimate the fat and muscle volume changes in musculocutaneous flaps during long-term follow-up. METHODS:  We conducted a retrospective analysis of 35 patients after musculocutaneous flap reconstruction...

BACKGROUND:  The use of caffeine is not recommended prior to elective microsurgery due to its demonstrated negative effects on vessel anastomosis by the presumed sympathomimetic induction of vasoconstriction. In this study, we aimed to elucidate the systemic and local effects of caffeine on vessel diameter, anastomosis patency, and degree of intimal hyperplasia during the healing process. METHODS:  Twenty-five rats were randomly assigned to five groups: (1) negative control, (2) preoperative systemic caffeine, (3) postoperative systemic caffeine, (4) perioperative systemic caffeine, and (5) a local caffeine group...

BACKGROUND:  Delayed autologous breast reconstruction is commonly recommended in patients requiring postmastectomy radiation. This study examines gross and histologic changes in the breast skin of patients who have undergone postmastectomy radiation to help determine when radiation-induced skin changes begin to stabilize. METHODS:  A prospective pilot study was conducted on eight patients with invasive breast cancer who required mastectomy and radiotherapy. At the time of mastectomy and 2, 4, 6, 8, and 12 months after completion of radiotherapy, a punch biopsy was taken from the radiated mastectomy skin of each patient...

BACKGROUND:  The anterolateral thigh (ALT) perforator flap is one of the most widely used flaps in reconstructive microsurgery. This study investigated a previously unexplored and clinically relevant aspect of perforator anatomy: the "box junction" (BxJn), the point at which the perforator arises from its source vessel. Negotiating the BxJn can be a challenging and time-consuming step in flap harvest, due to the neurovascular structures in the area which must be protected from injury...

BACKGROUND:  In 1964, faced with the challenge of traumatic amputation, a team of surgeons at Clinica Guayaquil was convinced that the transplantation of a hand could significantly improve function and quality of life for the recipient. With a current but basic understanding of immunosuppression, the surgeons identified a recipient and waited for the correct donor. A human hand transplant had never been performed to date. METHODS:  The surgeons' criteria for the recipient included a young healthy individual who had sustained a traumatic amputation at the distal forearm level with full motion of the proximal joints...

BACKGROUND:  Microsurgical replantation of the thumb and digits has become an increasingly familiar technique in clinical practice worldwide. However, successful digit replantation does not always provide better hand function than revision amputation. Little information is available regarding predictors of motor skill activities of replanted hands. Therefore, we retrospectively evaluated hand dexterity after single-digit replantation at a minimum follow-up of 1 year and analyzed the factors influencing dexterity...

BACKGROUND:  Lower extremity soft tissue sarcoma treatment has evolved from primarily amputation procedures toward limb salvage. This series assesses whether soft tissue sarcoma tissue defects, extensive enough to require microsurgical reconstruction, can reliably result in preservation of ambulation, as well as objectively evaluate functional outcomes utilizing a patient-reported validated scale. It will also look at whether immediate functional muscle reconstructions and tendon transfers can be successful at restoring ambulation, potentially expanding the indications for limb salvage procedures...

BACKGROUND:  The abdomen remains the most popular and reliable donor site for autologous breast reconstruction. Some patients, however, lack sufficient tissue to recreate an aesthetic breast mound using a single-pedicle, deep inferior epigastric perforator (DIEP) flap, particularly when matching a contralateral native breast. The amount of abdominal skin and/or soft tissue reliably supplied by one vascular pedicle is frequently insufficient to adequately restore the breast skin envelope and "footprint...

INTRODUCTION:  The creation of skin flaps based on small perforator vessels is an increasingly popular procedure nowadays; the optimization of their blood supply enhances surgical success. This study evaluates the effects on the flowmetries of 7 days' negative pressure application on the skin surface overlying the muscle fascia emergence of periumbilical perforators of the deep inferior epigastric artery (DIEA). METHODS:  Ten volunteer participants were enrolled...

BACKGROUND:  One aim of unilateral postmastectomy breast reconstruction (BR) is to restore symmetry with the contralateral breast. As such, unilateral prosthetic reconstruction often requires a contralateral symmetry procedure (CSP). There is sparse literature on the impact of CSPs on long-term patient-reported outcomes (PROs) such as satisfaction and health-related quality of life (HRQoL). This study aims to describe PROs following CSPs, using a validated PRO tool, BREAST-Q. The hypothesis is that CSPs are associated with greater patient-reported satisfaction and HRQoL...

BACKGROUND:  Indocyanine green (ICG) fluorescence lymphography (ICGLG) that can visualize the lymphatic vessel and its flow noninvasively and dynamically was developed in 2007. It is frequently used to observe the function and pathway of the lymphatic vessels. ICGLG is simple and easy to perform, and it is useful for understanding the condition of the lymphatic system in real time. However, its protocol is not standardized. In addition, the lymphatic flow is enhanced by an exercise load such as walking...

BACKGROUND:  Recent evidence documenting high success rates following microvascular diabetic foot reconstruction has led to a paradigm shift in favor of more aggressive limb preservation. The primary aim of this study was to examine reconstructive and functional outcomes in patients who underwent free tissue transfer (FTT) for recalcitrant diabetic foot ulcers (DFUs) at our tertiary referral center for advanced limb salvage. METHODS:  Between June 2013 and June 2016, 29 patients underwent lower extremity FTT for diabetic foot reconstruction by the senior author (K...

BACKGROUND:  Ischemia-reperfusion injury (IRI) precipitates acute rejection of vascularized composite allografts (VCA). Hyperbaric preservation of tissues ex vivo, between harvest and revascularization, may reduce IRI and mitigate acute rejection of VCA. METHODS:  A porcine heterotopic musculocutaneous gracilis flap model was used. In phase 1, control autografts ( n  = 5) were infused with University of Wisconsin Solution (UWS) and stored at 4°C for 3 hours...

BACKGROUND:  Indocyanine green (ICG) videoangiography is routinely used to evaluate skin and organ perfusion and to assess patency rates of microvascular anastomoses. This study uses ICG angiography as a novel approach to qualitatively and quantitatively evaluate bone perfusion of microvascular fibula grafts intraoperatively and to assess the effect of fibula segment length and number of osteotomies on bone perfusion. METHODS:  All patients planned for mandible reconstruction using a microvascular fibula graft between January 2013 and May 2017 were considered for this study...
