objectives: microtia is the most commonly seen congenital ear defect, and involves an auricular deformity either unilaterally or bilaterally. the aim of this study was to fabricate silicone prostheses for a child with bilateral microtia using an innovative technique. methods: this method involved the construction of bilateral ear prostheses using clips, which were located within the layers of t...

BACKGROUND Total ossicular replacement prostheses (TORP) are often used to re-establish ossicular coupling of sound in an ear lacking a stapes supra-structure. The use of TORPs, however, is associated with a 2/3 five year failure rate due to their anatomic instability over time in the middle ear. The use of autologous fat to try and stabilize TORPs may improve long-term results with this challe...

INTRODUCTION AND OBJECTIVE Many designs of prostheses are available for middle ear surgery. In this study we propose a design for a new prosthesis, which optimises mechanical performance in the human middle ear and improves some deficiencies in the prostheses currently available. Our objective was to design and assess the theoretical acoustic-mechanical behaviour of this new total ossicular rep...

Introduction Loss of an auricle may be due to congenital disease, trauma, or surgical removal of benign or malignant tumors. Auricular defects can be repaired, or reconstructed with autogenous tissue, but this may be unsuitable in many situations. Additionally the use of autogenous tissues requires harvesting a graft there by adding a surgical site. A good alternative is to develop an auricular...

Among the many existing hearing problems, there are those that need to be corrected through the replacement of the ossicles of the middle ear with a prosthesis. The type of the prosthesis used in the rehabilitation of the middle ear, total ossicular replacement prosthesis (TORP) or a partial ossicular replacement prosthesis (PORP) depends of the level of the ossicular impairment [1,2]. In the p...

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 ...

results utilizing autologous stem cell populations to treat craniofacial defects is a promising field of ongoing investigations. studies show that cartilage stem/progenitor cells (cspcs) are highly chondrogenic and can produce elastic reconstructive material with long-term tissue restoration. conclusions auricular reconstruction surgery is a challenging plastic procedure that requires great exp...

Human middle-ear is the key component of the auditory system. Its function is to transfer the sound waves through the ear canal to provide sufficient stimulus to the fluids of the inner ear. Degradation of the ossicles that transmit these sound waves from the eardrum to the inner ear leads to hearing loss. This problem can be overcome by replacing one or more of these ossicles by middleear pros...
