Relación entre el video head impulse test (vHIT) y la prueba calórica en el estudio evolutivo de pacientes con neuritis vestibular
Resumen Introduccion y objetivos La prueba calorica es hasta ahora la prueba de referencia para el diagnostico y el examen de una hipofuncion vestibular unilateral. El video head impulse test (vHIT) valora el reflejo vestibulo-oculomotor, mediante el registro videoasistido de la maniobra impulsiva. Se pretende comparar la variacion de los resultados del vHIT y la prueba calorica en pacientes con neuritis vestibular respecto a su estado inicial en diferentes puntos de su evolucion, y comprobar su grado de correlacion entre si y con el test Dizziness Handicap Inventory (DHI). Metodos Exploracion en la misma sesion mediante vHIT y prueba calorica de 20 pacientes con neuritis vestibular. Valora…
Extra-tympanic electrocochleography in a normal population. A descriptive study.
Abstract Introduction and objectives Extra-tympanic electrocochleography is an electrophysiological register obtained after stimulating the cochlea with an audible stimulus. This stimulus is applied using an earphone over the external auditory canal, while the electrical activity is registered by surface electrodes. There are few studies that analyse normal electrocochleography in our environment. Thus, the main objective of our study was to regularise the values obtained with electrocochleography in ears without any otoneurological diseases. We explain in detail the process of obtaining the register. Methods Sixty healthy ears were studied by extratympanic electrocochleography. Statistical…
Audiologic and Subjective Evaluation of Baha ® Attract Device
We included 9 patients implanted with Baha® Attract. All our patients were evaluated by free field tonal audiometry, free field verbal audiometry and free field verbal audiometry with background noise, all the tests were performed with and without the device. To evaluate the subjective component of the implantation, we used the Glasgow Benefit Inventory (GBI) and Abbreviated Profile of Hearing Aid Benefit (APHAB). The auditive assessment with the device showed average auditive thresholds of 35.8dB with improvements of 25.8dB over the previous situation. Speech reception thresholds were 37dB with Baha® Attract, showing improvements of 23dB. Maximum discrimination thresholds showed an average…
Relationship between video head impulse test (vHIT) and caloric test in patients with vestibular neuritis.
Abstract Introduction and objectives The caloric test is the gold standard for the loss of vestibular function diagnosis. The video head impulse test (vHIT) assesses the same reflex by using a video-assisted examination of the impulsive manoeuvre. We intend to compare the variation of results of the vHIT and the caloric test in patients with vestibular neuritis with respect to their initial condition at two different moments of their evolution and to check the level of correlation between them and with that of the DHI test. Methods We explored 20 patients with neuritis by using both vHIT and the caloric test on the same day. We assessed the correlation between these two tests and with the D…
Electrococleografía extratimpánica en una población normal. Estudio descriptivo
Resumen Introduccion y objetivos La electrococleografia extratimpanica es un registro elecrofisiologico que refleja la actividad electrica acontecida en la coclea tras un estimulo sonoro. Se obtiene mediante la aplicacion del estimulo en el conducto auditivo externo y el registro de la actividad electrica mediante electrodos de superficie. Dada la escasa literatura existente acerca de la exploracion electrococleografica normal en nuestro medio, este estudio busca regularizar los valores obtenidos mediante esta exploracion en sujetos sin enfermedad otoneurologica y explicar detalladamente el proceso mediante el cual se obtiene el registro. Metodos Exploracion mediante electrococleografia ext…
Valoración audiológica y subjetiva del dispositivo Baha ® Attract
Resumen Se incluyeron en el estudio 9 pacientes implantados con el dispositivo Baha® Attract. A todos los pacientes se les realizo, con y sin el dispositivo, una audiometria tonal en campo libre, una audiometria verbal en campo libre, y una audiometria verbal con ruido de fondo, asi como la aplicacion de los cuestionarios Glasgow Benefit Inventory (GBI) y Abbreviated Profile of Hearing Aid Benefit (APHAB). Las valoraciones audiologicas con el dispositivo mostraron unos umbrales auditivos promedios de 35,8 dB, con ganancias medias de 25,8 dB. El umbral de recepcion verbal promedio con el dispositivo se situo en 37 dB, mostrando una ganancia de 23 dB. Los resultados promedio del umbral de dis…
