Compliance mismatch between stent graft and host artery may induce complications and blood flow disorders. However, few studies have been reported on stent graft compliance. This study aims to explore the deformation and compliance of stent graft in stented and unstented zones under three pressure ranges. Compliance of two stent grafts incorporated with polyurethane graft (nitinol-PU) and polye...

Two hundred twenty cases of unilateral chronic suppurative otitis media (CSOM) with dry central perforation were chosen for this study and myringoplasty were done. Age group ranged from 13 to 48 years. Four types of autogenous tissues were used as graft material. Grafting was done by underlay technique when temporalis fascia, tragal perichondrium, areolar tissue were used as graft material and ...

Rhinoplasty is indicated for improving nasal breathing, the appearance of the nose, mental well-being and self-confidence. In rhinoplasty, the most important factors are the surgeon's experience and sense of balance and beauty. Facial beauty is related to balance and the symmetry of different parts of the face, including the nose. Balance can be achieved by augmentation or reduction of the vari...

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...

OBJECTIVES Scarce data exist regarding the effect of acute graft pyelonephritis on kidney histology after a kidney transplant. This study sought to assess the kidney histology at 1 month, and kidney function at 1 year, after acute graft pyelonephritis in kidney transplant patients. MATERIALS AND METHODS All kidney transplant patients with acute graft pyelonephritis between October 2006, and D...

background: autologous skin graft is frequently used in the field of plastic, and reconstructive surgery. the engraftment is dependent upon revascularization and angiogenesis, which can be regulated by different factors. in addition to its hematopoietic effects, erythropoietin is shown to positively affect the wound healing process. objectives: we studied effects of human erythropoietin on reva...

Purpose: Sequential graft and Y-type graft are two different surgical procedures in coronary artery bypass grafting (CABG). The hemodynamic environment of them are different, that may cause different short-term surgical result and long-term patency. In this study, the short-term and long-term result of sequential and Y-type graft was discussed by comparing the hemodynamics of them. Materials an...

AIM The purpose of this study was to compare the efficacy of platelet-rich plasma (PRP), platelet-rich fibrin (PRF), and hydroxyapatite (HA) for reduction of pain and swelling, absence of dry socket, soft tissue healing, and bone regeneration after mandibular third molar extraction in human patients. MATERIALS AND METHODS Forty patients requiring extraction of mandibular third molars were ran...

OBJECTIVE We investigated the use of autologous platelet-rich plasma (PRP) to improve the success rate of fat graft myringoplasty in perforated tympanic membranes of rats. MATERIALS AND METHODS A total of 20 healthy Wistar albino female rats were divided into two groups. In Group 1, the left tympanic membranes were perforated and grafted with a fat graft that was harvested from the inguinal r...
