BACKGROUND Bone conduction (BC) threshold depression is not always by means of sensory neural hearing loss and sometimes it is an artifact caused by middle ear pathologies and ossicular chain problems. In this research, the influences of ear surgeries on bone conduction were evaluated. MATERIALS AND METHODS This study was conducted as a clinical trial study. The ear surgery performed on 83 pa...

This paper aims to describe the stereolithographic rapid prototyping of the ear prosthesis in an anotia case and to evaluate the advantages and disadvantages. Virtual model of the patient’s head was produced from the computerized tomography scan of the patient. Three-dimensional image of the healthy contralateral ear was extracted, inverted and re-located on the virtual model. Data was transfer...

TEM and SEM were used to evaluate the fate of eleven Plasti-pore prostheses left in the human middle ear for periods varying from seven to 34 months. It was evident that Plasti-pore is a relatively inert material based on its clinical performance, absence of gross fibrous tissue reaction from the middle ear, and the unchanged physical characteristics of the prosthesis. Micro-disintegration of t...

Due to the simplicity of their manufacture and placement, middle-ear prostheses are generally constructed using only a single 'ossicle'. The variety of pathologies frequently make it necessary to devise individual solutions and the results are often unsatisfactory. Many methods of improving the prostheses have been tried, with very mixed results. Even until recently, the fundamental assumptions...

Facial tissue loss is acquired as a result of congenital anomalies or acquisitional misshapen like tumoral lesions accidents. These defects in functional problems, esthetic concerns, and also psychosocial troubles could be repaired by plastic surgery reconstructed using facial prostheses. Conventional tissue-supported auricular prostheses meet lots challenges due to dependence on undercut adhes...

Abstract This study demonstrates a cost-effective portable fabrication system for 3D printing complex structures from polydimethylsiloxane (PDMS). Material development and characterisation allowed the design production of printer that is capable fabricating PDMS using photo-initiator LED curing process. A model participant’s ear was captured handheld scanner. These data were used to directly pr...

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 pa...
