1. The role of vein grafts in reconstructive head and neck microsurgery
Abstract Objective: Free tissue transfer is widely used for head and neck reconstruction. In certain circumstances, vein grafting is required to elongate free flap pedicles to connect them to appropriate recipient vessels. Because of controversy regarding the use of interposition vein grafts in free tissue reconstruction, this paper reports vein graft indic

2. Secondary healing strategy for difficult wound closure in invasive vulvar cancer: a pilot case-control study
OBJECTIVES: Despite the number of surgical advances and innovations in techniques over time, radical vulvectomy frequently results in substantial loss of tissue that cannot be primarily closed without tension, the mobilization of surrounding tissues or even the rotation of myocutaneous flaps. The aim of this study was to evaluate the feasibility of leaving

3. Panorama of Reconstruction of Skull Base Defects: From Traditional Open to Endonasal Endoscopic Approaches, from Free Grafts to Microvascular Flaps
Introduction A substantial body of literature has been devoted to the distinct characteristics and surgical options to repair the skull base. However, the skull base is an anatomically challenging location that requires a three-dimensional reconstruction approach. Furthermore, advances in endoscopic skull base surgery encompass a wide range of surgical path

4. Torque na instalação de implantes dentais pós-transplante de fíbula microvascularizado. / Torque in the installation of dental implants in posttransplant microvascularized fibula.
INTRODUÇÃO: A reabilitação mastigatória com implantes dentais tornou-se, atualmente, uma terapêutica comum e necessária para pacientes edêntulos. Técnicas em implantodontia são aperfeiçoadas constantemente, dentre as quais o torque, para fixação dos cilindros de titânio em osso, considerado fundamental no prognóstico de sucesso da osteointegra

5. Avaliação de proteção celular a isquemia de retalhos musculares com soluções preservadoras de tecidos em modelo de ratos / Avaliação de proteção celular à isquemia de retalhos musculares com soluções preservadoras de tecidos em modelo de ratos
The free flaps transfer and reimplantation of tissue has in common the exposure of the tissue to ischemia and different time of reperfusion which are important for the determination of the extent of the cellular injury, being sometimes irreversible. In the pre and trans-surgical procedure the control of the ischemic period is difficult. Although efforts are

6. Application of fibrin glue in microvascular anastomosis: comparative analysis with the conventional suture technique using an experimental free flap model / Aplicação da cola de fibrina em microanastomoses vasculares: análise comparativa com a técnica de sutura convencional utilizando um modelo experimental de retalho microcirúrgico
INTRODUCTION: Microvascular anastomosis is an important component of the free flap surgical procedure. Currently, the conventional suture is still considered the gold standard technique. However, it presents some problems for being technically demanding, time consuming and with a long learning curve. In looking for an easier and faster technique, alternative

7. Effects of superoxide dismutase and allopurinol on the survival of acute island skin flaps.
We have demonstrated previously that oxygen-derived free radicals are important mediators of tissue injury following ischemia (total venous occlusion) and reperfusion in small (3 cm X 6 cm) island skin flaps in rats. In this study, we evaluated extension of this concept to regional ischemia in large (8 cm X 8 cm) acute island skin flaps which were constructe

8. Simultaneous bilateral breast reconstruction with the transverse rectus abdominus musculocutaneous free flap.
OBJECTIVE: The purpose of the study was to assess the results and morbidity associated with simultaneous bilateral TRAM free flap breast reconstruction and describe refinements in its surgical technique. SUMMARY BACKGROUND DATA: Bilateral prophylactic total mastectomies might be an agreeable option for those patients at highest risk for breast cancer if auto

9. Fine structure of the stratum intermedium, stellate reticulum, and outer enamel epithelium in the enamel organ of the kitten.
Stratum intermedium, stellate reticulum and outer enamel epithelium at the secretion stage in lower second molars of 1 week old kittens were studied with the electron microscope after perfusion fixation. All cell types had a well-developed Golgi apparatus, free ribosomes and little RER. In the stratum intermedium, cytoplasmic processes occasionally contained
