INTRODUCTION Different types of titanium prostheses are used for different types of ossicular chain reconstruction (OCR). However, various ossicular chain problems require different types of reconstruction (incus or prosthesis). Recently, Vincent et al. published a new type of ossiculoplasty with a malleus replacement prosthesis (MRP). The details of this new prosthesis are described in their a...

A three-dimensional (3D) finite element (FE) model was developed to simulate the motion modes of the human middle ear structures. The model was based entirely on 3D reconstruction obtained from micro Computed Tomography (microCT) imaging. We solve the acoustics-structure interaction problem using COMSOL Multiphysics. Our results show that at low frequencies, the classical hinging motion is domi...

introduction: the use of ossicular graft material in ossicular chain reconstruction has significantly improved hearing results hearing after tympanoplasty and tympanomastoid surgery for chronic otitis media. today, otologists have a wide array of tools from which to choose, but may find it difficult to know which middle ear implant works best.   materials and methods: a prospective study of 80 ...

The middle ear apparatus is composed of three endochondrial ossicles (the stapes, incus and malleus) and two membranous bones, the tympanic ring and the gonium, which act as structural components to anchor the ossicles to the skull. Except for the stapes, these skeletal elements are unique to mammals and are derived from the first and second branchial arches. We show that, in combination with g...

IT ^generally held that the incus has a poor blood supply although it would appear that, in health, it is adequate. In disease, it has been observed that the long process of the incus is frequently necrosed and, as the result of the clinical examination of a recent case, it is interesting to consider the nutrition of this ossicle. A boy, now aged n , had a bicycle accident at the age of 5, was ...

INTRODUCTION Stapes fixation combined with disorders of the incudo-malleolar complex disorders requires a sound transmission reconstruction that often is difficult to solve. This circumstance can turn up in several pathologies and also in revision surgery for otosclerosis. PATIENTS AND METHODS We present our experience with four patients that underwent to malleostapedotomy with removal of the...
