BACKGROUND Operative choices for aortic root disease include traditional root replacement with a composite valved graft as well as various valve-sparing and root repair procedures. OBJECTIVES To report our experience with traditional composite graft aortic root replacement by a single surgeon over a 25-year period in 449 patients, focusing on long-term survival and freedom from late reoperati...

Implant therapy in the atrophic posterior maxilla becomes challenging in the presence of reduced maxillary bone height. Sinus augmentation can be performed for resolving this condition prior to implant placement. The aim of this article was therefore to evaluate implant survival rates in the grafted sinus taking into account the influence of the implant surface, graft material, and implant plac...

BACKGROUND The composite graft from the conchal cartilage is a graft that is often used, especially in surgery on the nose, due to its capacity to resolve problems of cover and tissue deficit, arising from the removal of neoplasms or as the result of trauma, burns or following over-aggressive rhinoplasty. We have started to use skin-perichondrium-cartilage graft from the ear to cover large area...

BACKGROUND The once-daily (QD), prolonged-release formulation of tacrolimus has been shown to improve adherence versus twice-daily (BD) tacrolimus. Treatment nonadherence in transplant recipients has been associated with poor graft outcomes. METHODS This open-label, parallel-group study randomized adults with end-stage renal disease undergoing primary kidney transplantation or retransplantati...

OBJECTIVES The purpose of our study was to establish, with an entirely noninvasive method, transthoracic Doppler echocardiography, criteria for patency of composite left internal thoracic artery grafts when placed on the left anterior descending artery and other branches of the left coronary system. METHODS The control group comprised 20 patients with single graft and 20 patients with composi...

This study aimed to investigate the surface roughness and gloss of composite resins after using two polishing systems and toothbrushing. Six composite resins (Durafill VS, Filtek Z250, Filtek Z350 XT, Kalore, Venus Diamond, and Venus Pearl) were evaluated after polishing with two polishing systems (Sof-Lex, Venus Supra) and after toothbrushing up to 40,000 cycles. Surface roughness (Ra) and glo...

Abstract Introduction Tympanoplasty is the main treatment of mucosal type chronic suppurative otitis media. Objective The aim present study was to compare clinical outcomes in terms healing and audiological two groups. authors used single layer graft (perichondrium with cartilage island) one group double grafts island composite plus temporalis fascia) were second group. Methods Forty patients c...

An instant blood-mediated inflammatory reaction (IBMIR) is elicited when islets come in contact with blood after intraportal transplantation. In contrast, endothelial cells (EC) readily tolerate contact with blood. A conceivable strategy to overcome IBMIR would be to create composite islet-EC grafts. Human islets were co-cultured with primary human aortic endothelial cells (HAEC) for 2-7 days t...

Eyelid reconstruction is complex and challenging since it is not only for structural and functional restoration, but also for an acceptable aesthetic result. In full thickness eyelid injuries, it will involve both anterior and posterior lamella. Therefore, when reconstructing the defect, it requires at least two layers; one will be a flap with blood supply, and the other can be a free graft. In...

BACKGROUND Numerous procedures are available for nipple reconstruction without a single gold standard. This study presents a method for reducing donor-site morbidity in nipple reconstruction using a composite nipple graft after transverse rectus abdominis musculocutaneous flap breast reconstruction. METHODS Thirty-five patients who underwent nipple reconstruction using a composite nipple graf...
