Resumen
El implante coclear Advanced Bionics HiRes Ultra V1 tiene una baja tasa de supervivencia a 7 años (30-33%), lo que requiere una monitorización cuidadosa. La percepción del habla se recupera después de la revisión, pero puede tardar hasta 9 meses en alcanzar los niveles anteriores.
Área de la Ciencia:
- Otorrinolaringología
- Ingeniería Biomédica
- Neurociencia
Sus antecedentes:
- La fiabilidad del dispositivo de implante coclear es crucial para la rehabilitación auditiva.
- Los dispositivos internos Advanced Bionics HiRes Ultra y Ultra 3D V1 han sido objeto de acciones correctivas voluntarias en campo.
- Comprender las tasas de fallo del dispositivo y su impacto en la percepción del habla es esencial para el manejo del paciente.
Objetivo del estudio:
- Determinar las tasas de fallo y revisión de los dispositivos internos Advanced Bionics HiRes Ultra y Ultra 3D V1.
- Analizar el curso temporal de los cambios en la percepción del habla en pacientes con estos dispositivos.
- Evaluar la eficacia de las cirugías de revisión en los resultados de la percepción del habla.
Principales métodos:
- Serie de casos retrospectiva realizada en un centro de referencia terciario.
- Análisis de datos de fallo del dispositivo, cirugía de revisión y percepción del habla para pacientes adultos y pediátricos.
- Se utilizaron pruebas de percepción del habla para seguir el rendimiento a lo largo del tiempo, tanto antes como después de la revisión.
Principales resultados:
- Se observó una tasa significativa de fallo del dispositivo, con tasas de supervivencia a 7 años del 30,6% en adultos y del 33,3% en niños.
- Se observaron descensos en la percepción del habla tan pronto como 6-12 meses antes de la cirugía de revisión.
- Tras la revisión, se observó una recuperación de la percepción del habla en 3 meses y se estabilizó a los 9 meses.
Conclusiones:
- Los dispositivos V1 presentan una tasa de supervivencia preocupantemente baja, lo que sugiere un potencial de degradación adicional con el tiempo.
- La recuperación de la percepción del habla después de la cirugía de revisión es factible, pero requiere un período sustancial (hasta 9 meses).
- Se recomienda una monitorización rigurosa de la integridad del dispositivo y la percepción del habla, especialmente para los receptores pediátricos, para gestionar el impacto de los fallos del dispositivo.

01:15Subliminal Perception

Subliminal perception refers to the processing of sensory information that occurs below the level of conscious awareness. Researchers study subliminal perception by presenting a stimulus, such as a word or image, very quickly, typically around 50 milliseconds. This rapid presentation is often followed by another stimulus, such as a pattern of dots or lines, which blocks further mental processing of the initial stimulus. As a result, if participants cannot identify the initial stimulus better...

01:25Factors Affecting Perception
2.7K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

Perception is a fundamental psychological process that enables individuals to organize, interpret, and consciously experience sensory information. This process is crucial for understanding and interacting with the world around us. It includes both bottom-up and top-down processing, each playing a distinct role in how we perceive our environment.
Bottom-up processing begins at the sensory level, where receptors detect external environmental stimuli. These could include the tactile sensation of...

01:21Gestalt Principles of Perception
1.2K
Gestalt principles provide a framework for understanding how humans perceive objects as unified wholes within their context. These principles are essential in explaining the cognitive processes that make sense of complex visual stimuli by organizing them into coherent groups. One fundamental principle is proximity, which posits that objects located close to each other are perceived as a collective group. For instance, when dots are positioned near one another, the visual system interprets them...

01:17Auditory Perception
1.1K
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

Extrasensory perception, or ESP, suggests the ability to perceive events beyond the conventional senses of sight, hearing, and touch. Parapsychologists, who research ESP and related psychic phenomena, categorize ESP into three main types: precognition, telepathy, and clairvoyance.
Precognition involves foreseeing future events, such as predicting an accident before it happens. An example of precognition could be someone dreaming about a specific event, like a car crash, which then occurs...
