BACKGROUND: The scope of microvascular tissue transfer in the Head and Neck reaches from coverage of simple soft tissue defects to complex 3-D reconstructions using multiple or chimeric flaps. This paper summarises the presentation given at the Congress of the French Society of Oral and Maxillofacial Surgery in Marseille 2017. It was the aim of our work to add further elements to this wide spectrum of reconstructive possibilities. METHODS: For patients with small intraoral soft tissue defects in whom the use of a radial forearm flap would not be justified because of its donor site morbidity, but who nevertheless would take a benefit from a small free flap, we used mini-perforator flaps from the lower leg...

BACKGROUND: Fat grafting experiences a regeneration process from free lipoaspirate to intact adipose tissue. The adipose extracellular matrix (ECM) provides the structure and biochemical support for the surrounding cells, and is regulated by inflammatory cells, like macrophages. It is hypothesized that transferred fat undergoes ECM remodeling after fat grafting and the process can be regulated by macrophage infiltration. METHODS: Lipoaspirate was injected subcutaneously into the back of nude mice...

Joachim Denner
The chronic shortage of human transplants to treat tissue and organ failure has led to the development of xenotransplantation, the transplantation of cells, tissues and organs from another species to human recipients. For a number of reasons, pigs are best suited as donor animals. Successful, routine xenotransplantation would have an enormous impact on the health of the human population, including the young, who sometimes require a replacement organ or islet cells, but especially the elderly, who more often suffer the consequences of organ failure...

CONTEXT: The internal mammary artery perforator vessels (IMPV) as a recipient in free flap breast reconstruction offer advantages over the more commonly used thoracodorsal vessels and the internal mammary vessels (IMV). AIMS: This study was designed to assess the anatomical consistency of the IMPV and the suitability of these vessels for use as recipients in free flap breast reconstruction. PATIENTS AND METHODS: Data from ten randomly selected female patients who did not have any chest wall or breast pathology but had undergone a computed tomography angiography (CTA) for unrelated diagnostic reasons from April 2013 to October 2013 were analysed...

In the past decade, biological nurturing and activation of maternal and infant instincts after birth have constituted a major advance in clinical breastfeeding support. Yet, physiologic breastfeeding initiation is not enough to ensure ongoing pain-free and effective breastfeeding for many pairs. Current interventions, including "hands-off" mammalian approaches, do not improve breastfeeding outcomes, including in randomized controlled trials. Back-arching, difficulty latching or staying on the breast, and fussing at the breast are common signs of infant positional instability during breastfeeding...

Assessment of tissue perfusion can be a challenge for the hand surgeon. Indocyanine green (ICG) angiography has been shown to be a valuable adjunct to physical examination and clinical judgment when there is a concern for tissue perfusion. The use of this technology has risen sharply in recent years in reconstructive surgery. Applications of ICG angiography have been developed throughout the field of surgery, including breast surgery, free tissue transfer, bowel surgery, neurosurgery, and lymphatic reconstruction...

Comprehending the mechanism of thermal transport through biological tissues is an important factor for optimal ablation of cancerous tissues and minimising collateral tissue damage. The present study reports detailed mapping of the rise in internal temperature within the tissue mimics due to NIR (1064 nm) laser irradiation, both for bare mimics and with gold nanostructures infused. Gold nanostructures such as mesoflowers and nano spheres have been synthesized and used as photothermal converters to enhance the temperature rise, resulting in achieving the desired degradation of malignant tissue in targeted region...

OBJECTIVE: In the current healthcare climate, there is increased focus on medical errors, patient outcomes, and the influence of resident participation on these metrics. Other studies have examined the influence of resident involvement on surgical outcomes, but the arena of microsurgery, with added complexity and learning curve, has yet to be investigated. DESIGN: A retrospective analysis of the American College of Surgeons National Surgical Quality Improvement Program database was performed to find patients undergoing procedures with free tissue transfer by screening for Current Procedural Terminology codes...

Murine cardiomyocytes have been extensively used for in vitro studies of cardiac physiology and new therapeutic strategies. However, multicellular preparations of dissociated cardiomyocytes are not representative of the complex in vivo structure of cardiomyocytes, non-myocytes and extracellular matrix, which influences both mechanical and electrophysiological properties of the heart. Here we describe a technique to prepare viable ventricular slices of adult mouse hearts with a preserved in vivo like tissue structure, and demonstrate their suitability for electrophysiological recordings...

PURPOSE OF REVIEW: This article reviews the recent literature on the perioperative care of head and neck surgical patients undergoing free tissue transfer. RECENT FINDINGS: As the overall success of head and neck free flaps has plateaued above 95%, recent literature on perioperative flap management has focused on minimizing complications, length of stay, and cost of treatment. Current areas of research include preoperative risk stratification, preoperative and postoperative nutrition, intraoperative fluid management, postoperative level of care, postoperative antibiotic prophylaxis, defining the impact of comorbidities, and developing comprehensive evidence-based perioperative care protocols...

AIM: We propose our experience in soft tissue reconstruction in Hemifacial microsomia using a free fascioadiposal flap. MATERIAL OF STUDY: Hemifacial microsomia (HFM) is a congenital disorder characterized by craniofacial malformation of one or both sides of the lower face. A 18-year-old female presented with hemifacial microsomia involving the left side. A free SCIA/SIEA fascioadiposal flap was transferred to the left face for soft tissue augmentation. RESULTS: The immediate postoperative course of the patient was uneventful, with no complication and adequate augmentation in contour deformity was achieved...

Radial club hand is a complex congenital abnormality of the radial or pre-axial border of the upper extremity. It has a wide range of phenotypes from hypoplasia of the thumb to complete absence of the radius and the first ray. Centralization with tendon transfer is a popular method for maintaining the correct position of radial club hand. On the other hand, various corrections were devised, e.g. radialization after distraction to emphasize the fact that the head of the ulna is positioned under the radial carpal bones and is no longer placed in a slot in the center of the carpus, microvascular epiphysis transfer, gradual correction using Ilizarov method, for Bayne Type III or Type IV...

BACKGROUND: Early detection of compromised free flap perfusion is critical. A common modality of thrombosis detection, physical exam augmented with hand-held Doppler, only provides intermittent data and is insensitive to venous compromise. Visible light spectroscopy (VLS) provides continuous, non-invasive evaluation of tissue perfusion. We hypothesized that VLS is a more sensitive and specific monitoring method for early detection of post-operative flap compromise than intermittent, hand-held Doppler and clinical exam...

The reconstruction of large cranial and scalp defects is a surgical and esthetic challenge. Single autologous tissue transfer can be insufficient due to the defect size and the anatomic complexity of the recipient site. Alloplastic patient-specific preformed implants can be used to recover hard tissue defects of the neurocranium. Nevertheless, for long-term success adequate soft tissue support is required. In this brief clinical study, the authors describe calvarian reconstruction in a 33-year-old patient with wound healing disorder after an initial resection of ependymoma...

OBJECTIVE: Postoperative use of anticoagulation after free tissue transfer in head and neck ablative procedures is common practice, but a clear protocol has not been well established. The outcome measures including total flap failure, thrombosis, and hematoma formation for different anticoagulation regimens in free tissue transfer in the head and neck were reviewed. DATA SOURCES: PubMed, Ovid, and Cochrane databases were examined for patients who underwent free tissue transfer following head and neck ablative procedures...

Treatment of brachial plexus injuries has slowly improved over the last 45 years. Changes in strategy, techniques, microsurgical equipment and technology have expanded the surgical options to reconstruct these life altering, highly complex injuries. The surgical armamentarium includes neurolysis, nerve repair, nerve grafting, nerve transfers, tendon transfer, muscle transfer and other soft tissue and bony procedures. In this article we have selected five surgical procedures (Oberlin's procedure, Leechavengvongs' procedure, free functional muscle transfer, radial nerve tendon transfers and C5-C6 nerve grafting in obstetrical birth palsy) that have consistently given us good results in our patients who require surgical reconstruction...
