BACKGROUND: Free tissue transfer has fundamentally changed head and neck surgery, enabling reliable reconstruction of large defects with better function and aesthetics. This study assesses two decades of trends in free flap reconstruction, and how disease incidence, survival, surgeon caseload, team approach, and technology have impacted practice. METHODS: Retrospective analysis of 1027 head and neck free flaps from 2006 to 2022. Outcomes examined include chronological changes in flap selection, indication, length of stay, incorporation of virtual surgical planning (VSP), annual caseload, survival, and their associations with the single versus multi-team approach...

OBJECTIVE: This study sought to quantify the deep venous thrombosis (DVT) incidence in head and neck cancer (HNC) patients undergoing free tissue transfer and to identify independent predictors of postoperative DVT. MATERIALS AND METHODS: This is a cross-sectional study of the National Surgical Quality Improvement Program database from 2010 through 2020. The sample included all HNC surgical patients treated with free flap reconstruction. The study outcome was the presence of a DVT requiring treatment within 30 days of surgery...

BACKGROUND: Patients with solid organ transplant (SOT) are at increased risk of developing aggressive cutaneous malignancies due to their immunosuppression, particularly cutaneous squamous cell carcinoma (cSCC). PURPOSE: There is limited data regarding SOT patients with locally advanced cSCC requiring radical surgery and microvascular free tissue transfer (MVFTT). Our objectives were to characterize outcomes in SOT patients and compare them with a non-SOT cohort...

Although many free tissue transfers have been performed, free flap loss can still occur because of vascular compromise. To facilitate microsurgery, we invented the axial-view microscope (aMS), a new type of microscope that can axially visualize vessel stumps. The aMS was combined with an optical microscope, the so-called bird's-eye-view microscope (bMS). Using our aMS, we observed the cross-sections of the following 12 arteries during vascular anastomosis: three deep inferior epigastric arteries, three suprathyroid arteries, two thoracodorsal arteries, two jejunal arteries, one lateral circumflex femoral artery, and one facial artery...

BACKGROUND: Arteriovenous (AV) loops help to overcome absent or poor-quality recipient vessels in highly complex microvascular free flap reconstruction cases. There are no studies on blood flow and perfusion patterns. The purpose of this study was to evaluate and compare intraoperative hemodynamic characteristics of AV loops followed by free tissue transfer for thoracic wall and lower extremity reconstruction. METHODS: this prospective clinical study combined Transit-Time Flowmetry and microvascular Indocyanine Green Angiography for the assessment of blood flow volume, arterial vascular resistance and intrinsic transit time at the time of AV loop construction and on the day of free flap transfer...

INTRODUCTION:  The use of perforator flaps has become more popular with improvement of surgical technique, technology, as well as understanding of microvascular anatomy. The selection of well-perfused angiosomes is critical to the successful outcome of patients undergoing free tissue transfer. The number of perforators that are needed is dependent upon the surface area of the flap being harvested; however, there have been no studies to assess the optimal surface area supplied by each perforator...

INTRODUCTION: The aim was to reflect the established interdisciplinary aspects of general/abdominal and plastic surgery by means of a narrative review. Methods: (i) With specific references out of the medical literature and (ii) own clinical and perioperative as well as operating technical and tactical management experiences obtained in surgical daily practice, we present a choice of options for interdisciplinary cooperation that could be food of thought for other surgeons. CONTENT: - Decubital ulcers require pressure relieve, debridement and plastic surgery coverage, e...

UNLABELLED: Microsurgical reconstruction is nowadays the treatment of choice of several head and neck deformities that otherwise could be repaired with limited or unsatisfactory results. The forearm free flap has its own goals expecially the possibility to reconstruct small and extremely specialized anatomical structures such as the soft palate. The abuse of drugs like cocaine, generally taken by sniffing, can produce vascular impairment in nasal and oral tissues producing, as long as the abuse is kept, necrosis of facial anatomical structures and increase of the empty space in the depth of the face or nose...

OBJECTIVES: To describe our technique, review indications, and evaluate the outcomes of the minimal access approach for recipient vessel identification in microvascular tissue transfer. METHODS: Retrospective chart review of all patients who underwent microvascular reconstruction using the minimal access technique between 2015 and 2021. RESULTS: We report 236 cases, comprising 214 patients with a mean age of 60.2 years (3-88). The most common primary defect sites were the mandible (22...

Free-tissue transfer reconstruction in patients with sickle cell anemia risks failure due to polymerization of sickle hemoglobin within the flap microcirculation. However, outcomes vary, as the amount of polymerization is dependent on factors such as disease phenotype/diagnosis, degree of hypoxia, and intracellular dehydration. Most of the literature focuses on patients with sickle cell disease, which produces higher concentrations of sickle hemoglobin and, therefore, is a contraindication to microvascular reconstruction...

Introduction With a better understanding of local fasciocutaneous flaps, local muscle flaps, split skin grafts, myocutaneous flaps, cross-leg flaps, and microvascular free tissue transfers, soft tissue management has improved during the past few years. The present study was conducted to study the various modalities of resurfacing lower extremity wound defect and their clinical outcome in patients with lower extremities trauma. Methodology An observational study was done in the Department of Plastic Surgery at Baba Raghav Das (BRD) Medical College, Gorakhpur (UP), and Maharshi Vashishtha Autonomous State (MVAS) Medical College, Basti (UP), with 30 patients admitted for lower limb resurfacing irrespective of the cause of wound defect from December 2020 to November 2021...

Patent microvascular anastomoses are essential for successful free tissue transfer. Early accurate detection of microvascular compromise is required for flap salvage. Adjunctive monitoring techniques, in addition to clinical examination, are increasingly used to detect flap compromise. This systematic review synthesized and appraised the literature to determine the efficacy of different postoperative monitoring technologies. Rates of flap takeback, salvage, failure, and mean time to detection of microvascular compromise were extracted, synthesized, and reviewed...

Soft tissue reconstruction of the upper extremity requires consideration of wound bed status, varied anatomic composition, future function and tissue match, whether in thickness, pliability or involvement of other tissue components. Of the options available, microvascular free tissue flaps allow maximal customizability with the avoidance of long-term donor site morbidity. Free tissue transfers have evolved, given increased surgical proficiency, from direct vessel-based flaps to septocutaneous vessel-based flaps, to musculocutaneous perforator flaps, and most recently to free-style free flaps...

OBJECTIVES: Microvascular free tissue transfer is routinely used for reconstructing midface defects in patients with malignancy, however, studies regarding reconstructive outcomes in invasive fungal sinusitis (IFS) are lacking. We aim to describe outcomes of free flap reconstruction for IFS defects, determine the optimal time to perform reconstruction, and if anti-fungal medications or other risk factors of an immunocompromised patient population affect reconstructive outcomes. METHODS: Retrospective review of reconstruction for IFS (2010-2022)...

BACKGROUND: The selection of reliable recipient vessels is essential for successful free tissue transfer. The use of internal mammary intercostal perforators (IMAPs), instead of the internal mammary vessels as the recipient vessels, has been described in breast reconstruction. Debates exist regarding the reliability of these perforators as recipient vessels because of their variability in location and caliber. The aim of this paper was to conduct a systematic literature review and meta-analysis to determine the reliability of the IMAPs as recipient vessels...

INTRODUCTION AND IMPORTANCE: Scalp tumors are diverse, with the characteristics of individual tumors depending on the cell lineage. Invasive squamous cell carcinoma and sarcomas of the scalp are a variety of uncommon, aggressive neoplasms of the head and neck. Resecting large invasive tumors causes extensive full-thickness scalp defects, and repairing these defects remains challenging. CASE PRESENTATION: The authors present two successful cases using a staged approach with titanium mesh and free tissue transfer (anterolateral thigh flap) technique...
