PURPOSE To compare a Teflon prosthesis to a piston-type wire/Teflon prosthesis assessing auditory results post-Stapedectomy. MATERIAL AND METHODS We conducted a randomized controlled blinded clinical study from June 2003 to August 2004 at the Otorhinolaryngology, and Head and Neck Surgical Wards at the highly specialized medical unit of "La Raza" General Hospital National Medical Cen ter in M...

INTRODUCTION When summarizing the performance achieved by users of a cochlear prosthesis, results are typically reported as means and standard deviations of speech recognition scores1 (also Brimacombe and Beiter, unpublished observations, 1992). These statistics constitute a valid description of the data only when scores are distributed normally, ie, as a bell-shaped On the basis of theoretical...

The palate shape of four speakers was changed by a prosthesis which either lowered the palate or retracted the alveoles. Subjects wore the prosthesis for two weeks and were recorded several times via EMA. Results of articulatory measurements show that speakers use different compensation methods at different stages of the adaptation. They lower the tongue immediately after the insertion of the p...

Early blind (EB) individuals can recognize bidimensional shapes using a prosthesis substituting vision with audition (PSVA) and activate right dorsal extrastriate visual cortex during the execution of this task. The present study used repetitive transcranial magnetic stimulation (rTMS) to further examine the functional role of this structure in the successful use of the PSVA. Moreover, we inves...

Maxillofacial prosthodontics is an art and science which provides life like appearance to the person with facial deformity. Maxillofacial prosthetic rehabilitation for acquired defects has become more complex and sophisticated with advancement in techniques and materials. This case report describes the clinical and laboratory procedure for fabricating an auricular prosthesis for a patient with ...

OBJECTIVES Our study aimed to highlight the effectiveness of palatal lift prosthesis in patients with velopharyngeal insufficiency with previous operated cleft palate. METHODS This study was done undertaken January 2008 to December of 2009 in the Phoniatic unit of Alnoor Specialist Hospital, Makkah, Saudi Arabia. Ten patients of ≥ 8 years to ≤ 10 years of age, who had previously undergone sur...

Piston-stapedotomy is the most common method for hearing restoration in patients with otosclerosis. In this study, we have experimentally examined a prototype of a new chamber stapes prosthesis. The prototype was implanted in a human cadaver temporal bone. The round window vibrations before and after implantation were measured for the acoustic signal (90 dB SPL, 0.8-8 kHz) in the external audit...

In this article some of the different technologies and its functioning as well as some technological aids for people with partial or total auditory deficiency will be presented. The objective of the auditory rehabilitation is to develop the capacity of auditory perception to the individual carrying auditory deficiency, with aid of devices that can amplify the sound. Between these devices, we ci...
