cavernous hemangioma is a rare benign tumor of the internal auditory canal (iac) of which fourteen cases have been reported so far. tinnitus and progressive sensorineural hearing loss (snhl) are the chief complaints of the patients. audiological and radiological planes, ctscan, and magnetic resonance image (mri) studies are helpful in diagnosis. the only choice of treatment is surgery with elec...

abstract fixed dental prosthesis success requires appropriate impression taking of the prepared finish line. this is critical in either tooth supported fixed prosthesis (crown and bridge) or implant supported fixed prosthesis (solid abutment). if the prepared finish line is adjacent to the gingival sulcus, gingival retraction techniques should be used to decrease the marginal discrepancy among ...

The authors report on an actuated positioning device for a cochlear prosthesis insertion procedure. The device consists of multiple high-aspect ratio fluidic actuator chambers integrated with a high-density silicon cochlear electrode array and manufactured in a taperedhelix form. Actuation chambers with cross-sectional sizes as small as 40 · 200 lm and lengths of 30 mm have been fabricated usin...

A carefully designed study was undertaken in 1982 to evaluate the performance of individuals who received the Nucleus 22-channel cochlear implant. All patients were profound-totally deaf, adults with a postlingual onset of impairment. The preoperative evaluation, prosthesis fitting, training, and postoperative testing were consistent across clinics. Single-subject studies, where each patient ac...

The purpose of this study is to introduce the procedure and results of a combined free flap reconstruction with an external ear prosthesis after tumor extirpation from the lateral side of the head. Over the last 3 years, four patients have undergone total auricle extirpation for varying tumor processes. Each was reconstructed with a radial forearm flap, preserving the external auditory meatus. ...

It is generally accepted that the development of erectile dysfunction is frequently attributed to both psychogenic factors as well as physiological alterations in neural, vascular, hormonal and endothelial function. Despite the advent of oral and intracavernosal erectile drugs, penile prosthesis implant remains a relevant and desired treatment option as many men became refractory to medical the...

introduction: tinnitus is a perception of sound without external source. for complete assessment of tinnitus, central auditory processing abilities should be considered in addition to the routine psychological evaluation of tinnitus characteristics. temporal processing is one of the important auditory skills that are necessary for complex higher level auditory processing.   materials and method...

background and aim: omega 3 of essential fatty acids, especially in fish oil form plays an important role in structural, functional, and biological aspects in body. omega 3 deficiency can have devastating effects on the nervous system and auditory. this study aimed to evaluate auditory threshold in n-3 fatty acid-deficient rat pups following supplementation of fish oil consumption during the suc...
