COMPLETE valvular replacement is the only feasible method for treatment of many cases of aortic valvular disease. While the long-term results will not be known for some time, the prognosis without operation, in carefully selected patients, is so poor as to justify this approach. Our total experience, consisting of a group of 16 such patients undergoing aortic replacement with the ballvalve pros...

When Policy Topic is covered Metal-on-metal total hip resurfacing with a device system approved by the U.S. Food and Drug Administration (FDA) may be considered medically necessary as an alternative to total hip replacement when the patient:  Is a candidate for total hip replacement; AND  Is likely to outlive a traditional prosthesis; AND  Does not have a contraindication for total hip resur...

Spinal fusion for degenerative disc disease has been associated with a variety of side effects, including increased morbidity, infection, failed back syndrome, pseudoarthrosis, and acceleration of degenerative changes in adjacent intervertebral discs and facet joints. Based on the experience of arthroplasty of hip and other joints, there has been an escalating in research emphasizing the design...

BACKGROUND Total ankle replacement is associated to a high revision rate. To improve implant survival, the potential advantage of prostheses with fixed bearing compared to mobile bearing is unclear. The objective of this study was to test the hypothesis that fixed and mobile bearing prostheses are associated with different biomechanical quantities typically associated to implant failure. METH...

The Vibrant Soundbridge is a semi-implantable “direct drive” hearing system for the treatment of loss. People who are unsuccessful users acoustic aids or dissatisfied with their have been successfully fitted device. comprised an external audio processor and internal vibrating ossicular prosthesis, which together convert environmental sound into vibratory signal delivered to inner ear. This uniq...

Introduction: The aim of this study was to evaluate the condition of the ossicular chain in patients requiring surgery for cholesteatoma.  Materials and Methods: In a retrospective analysis, the destruction of the individual and combined bony structures of the ear was described in 166 patients with cholesteatoma who went through surgery in our Otology Center between 2003 and 2009.  Results:...

Introduction:Different types of prosthesis are available for stapes replacement. Because there has been no published report on the efficacy of the titanium soft-clip vs the fluoroplastic Causse loop Teflon piston, we compared short-term hearing results of both types of prosthesis in patients who underwent stapedotomy due to otosclerosis.Materials and Methods:A total of 57 ears were included in ...

Objective Chronic otitis media most commonly causes an ossicular chain defect in incus. Different materials can be used for repair of this defect. In this study, the hydroxyapatite prosthesis, used for repair of the incus defect, was compared with the incus interposition. Methods Between 2010 and 2016, 27 female and 16 male patients who underwent ossiculoplasty due to an incus defect were stu...
