PURPOSE To assess the effect of a program of singing training on the voice of total laryngectomees wearing tracheoesophageal voice prosthesis, considering the quality of alaryngeal phonation, vocal extension and the musical elements of tunning and legato. METHODS Five laryngectomees wearing tracheoesophageal voice prosthesis completed the singing training program over a period of three months...

background:  conventional treatments after complicated injuries of the distal radioulnar joint (druj) such as darrach and kapandji-sauvé procedures have many drawbacks, which may eventually lead to a painful unstable distal ulna.  the development of druj prosthesis has significantly evolved over the past years. in this study, we assessed the outcome results of patients after druj implant arthro...

conclusions moderate ppm has no negative effect on echocardiographic trans-aortic pressure gradients or the patients’ nyha functional status after avr with a carbomedics prosthesis in the mid-term follow up. results of the 66 studied patients, 39 were male and 27 were female. the mean age of the patients was 43 ± 17 with a range of 6 - 76 years. implanted sizes of the carbomedics av prosthesis ...

A mitral prosthesis, when implanted, can distort the aortic annulus, forcing to downsize the aortic prosthesis. Changing the sequence of tying the sutures (the aortic prosthesis first, then the mitral prosthesis) allows to insert an aortic true-sized prosthesis. In case of associated tricuspid valve surgery, the aortic prosthesis protrudes over the anteroseptal commissure area. The sutures on t...

abstract   introduction: hearing impairment affects all aspect of individual life, especially auditory perception, while use of cochlear implant or hearing aids has been associated with appropriate effects in auditory performance. the aim of the present research was to comparing auditory perception in children with cochlear implant, hearing aids and normal hearing in tehran province. materials ...

STATEMENT OF PROBLEM Speech bulbs and palatal lift prostheses are used to improve oral-nasal balance in speakers with hypernasality resulting from velopharyngeal dysfunction. Fabricating such speech prostheses is often a protracted process, and the nasopharyngeal impression can be uncomfortable for the client. PURPOSE The purpose of this study was to develop and test a modular palatal lift pr...

objectives: this paper describes further improvement and preliminarily evaluation of a novel viscoelastic ankle-foot prosthesis prototype. the objective was to control the ankle hysteresis at slow and normal walking speeds. methods: inspired by the ankle biomechanics, in which the hysteresis differs based on the gait speeds, a manually damping control mechanism imbedded in the prosthesis for ad...

rapid prototyping (rp) is a technique of manufacturing parts by the additive layer manufacturing technology; where, a three-dimensional (3d) model created in a computer aided design (cad) system is sectioned into 2d profiles, which are further constructed by rp layer by layer. its use is not limited to industrial or engineering fields and has extended to the medical field for the manufacturing ...

X-ray and cineradiography measurements were used to compare the suspension effect and stability of a TSB trans-tibial prosthesis with an Icelandic Roll-On Silicone Socket (ICEROSS) system to that of a PTB trans-tibial prosthesis. The suspension effect was measured by the distance between the tibia and the socket in both suspension position and weight-bearing position in both type of prostheses....
