Background . Subungual squamous cell carcinoma (SCC) of thumb is a rare disease. However, it the most common malignancy affecting nail bed. Early recognition crucial and important for prompt diagnosis effective treatment. Often this tumour needs to be treated surgically with wide local resection, which results in defect thumb. If not handled appropriately, such defects render restriction functi...

approximately 25% of all oral cavity carcinomas involve the lips, and the primary management of these lesions is complete surgical resection. loss of tissue in the lips after resection is treated with a variety of techniques, depending on the extension and location of the defect. here we review highly accepted techniques of lip reconstruction and some of new trials with significant clinical res...

INTRODUCTION High-energy trauma of the hand often causes tissue loss involving bone, tendon and skin and is sometimes accompanied by devascularization of digits. Bone stabilization is the first step in the management of such injuries. MATERIALS AND METHODS A young patient presented composite tissue loss of the dorsum of his right (dominant) hand following an accident with a surface planer. Ti...

background and aims. connective tissue grafts with and without periosteum is used in regenerative treatments of bone and has demonstrated successful outcomes in previous investigations. the aim of present study was to evaluate the effectiveness of connective tissue graft with and without periosteum in regeneration of intrabony defects. materials and methods. in this single-blind randomized spli...

background: localized alveolar ridge defect may create physiological and pathological problems. developments in surgical techniques have made it simpler to change the confi guration of a ridge to create a more aesthetic and more easily cleansable shape. the purpose of this study was to compare the effi cacy of alveolar ridge augmentation using a subepithelial connective tissue graft in pouch an...

BACKGROUND The coverage of the atelocollagen membrane at the chondral defect after subchondral drilling might improve the beneficial effects for cartilage repair because of the prevention of scattering and accumulation of cells and growth factors from bone marrow within the chondral defect. On the other hand, it might block cells and factors derived from the synovium or cause high pressure in t...

Objective: In this study, the bone regeneration ability of polyacrylamide hydrogel and nanohydroxyapatite scaffolds (PAAH/NHA) and stem cells derived from adipose tissue (ADSCs) in the healing of critical sized bone defects in rabbit radius were assessed. Animals and procedures: 12 New Zealand white male rabbits were divided into 3 groups. The rabbits were anesthetized and 15 mm bone def...
