PURPOSE Various graft materials, such as synthetic and biological products, are used routinely in maxillofacial surgery. These materials are usually derived from porcine, bovine, and human tissues; some religious beliefs forbid the dietary use of substances from certain animal sources. The aim of this study was to evaluate the effect of religious belief on selecting different graft types used i...

PURPOSE The present investigation clinically and histologically evaluated the use of fresh-frozen bone in the reconstruction of maxillary alveolar ridges to confirm the effective bone fill and support for the placement of dental implants. PATIENTS AND METHODS Fifteen patients who had atrophic maxillary ridge necessitating bone block grafts prior to implant placement were submitted to maxillar...

The autogenous arteriovenous fistula (AVF) is the preferred access for chronic hemodialysis in patients with end-stage kidney disease. Careful examination of the upper extremity is essential for the creation of a successful fistula. The quality of the arterial and venous circulation should be well established prior to surgery. However, there are cases when the superficial venous system of the u...

Bone is one of the most dynamic tissues in the human body that can heal following injury without leaving a scar. However, in instances of extensive bone loss, this intrinsic capacity of bone to heal may not be sufficient and external intervention becomes necessary. Several techniques are available to address this problem, including autogenous bone grafts and allografts. However, all these techn...

BACKGROUND With the increasing use of hydroxyapatite orbital implants, the complication of exposure has become apparent to oculoplastic surgeons. Many kinds of patch grafts, such as sclera, dermis, and hard palate mucosa, have been used to cover exposed hydroxyapatite implants with inconsistent results. In this study, the authors use a newly developed technique, autogenous retroauricular myoper...

Dialysis access surgery is currently one of the most common vascular operations as the dialysis patient population increases. Although autogenous arteriovenous fistulae stand as the preferred method of access due to excellent patency and lower complication rates, grafts may provide alternative approaches when an autogenous fistula is impractical usually due to depleted veins. We aimed in this s...

background and aims. autogenous onlay bone grafting is a common procedure for alveolar ridge augmentation. it has been suggested that the amount of healed bone after this technique would be significantly less than the initial quantity. the aim of this study was to determine the relationship between the various parameters influencing the outcome of ridge augmentation procedures. materials and me...
