Comparison of ocular vestibular myogenic response by acoustic stimulation at 500 and 1000 Hz in healthy subjects.

Objective: To compare the amplitude of potentials by acoustic stimulation at 500 Hz versus 1000 Hz in healthy subjects.

Methods: 25 subjects; potentials were performed with acoustic stimuli burst-type at 500 and 1000 Hz with a stimulation rate of 5.1 at 100 dB in both ears.

[Analysis of the joint and a posteriori probability between primary empty sella, its comorbidities and audiovestibular pathology].

Background: Primary empty sella is a herniation of the sellar diaphragm into the pituitary space. It is an incidental finding and patients may manifest neurological, ophthalmological and/or endocrine disorders. Episodes of vertigo, dizziness, and hearing loss, have been reported.

Audiometric evaluation short and medium term in cochlear implants.

Objective: Our purpose is report the results of cochlear implant program in this Institute, since our first surgery from November 2007, until December 2012.

Material And Methods: A cross-sectional study, observational, descriptive, analyzing the information about thresholds before and after implantation, using patients files (diagnosis, onset of hearing loss, brainstem auditory evoked potential (BAEP), computed tomography (CT), magnetic resonance imaging (MRI), implanted ear, brand and model of cochlear implants (CI) and audiometric studies before and after the CI.

Results: We report the evolution of 68 patients, age ranged 1 year 8 months to 39 years 3 months old.

[Hearing gain with binaural-bimodal adaptation in patients with a cochlear implants].

Binaural hearing allows the optimal performance of the auditory system with a better perception of the sounds that make up language and better discrimination in noisy environments. The use of binaural-bimodal stimulation includes a combination of 2 different pacing modes: a cochlear implant in one ear , and acoustic stimulation through a conventional hearing aid in the other. The aim of this study is to determine the hearing gain in patients with cochlear implant alone and hearing aid.
