Using Pupillometry to Evaluate Balance in Patients Implanted with a Cochleo-Vestibular Implant.

Maintaining balance comes naturally to healthy people. In subjects with vestibulopathy, even when compensated, and especially if it is bilateral, maintaining balance requires cognitive effort. Pupillometry is an established method of quantifying cognitive effort.

(1) Background. Patients with bilateral vestibular disease (BVD) experience oscillopsia with a detriment to visual acuity (VA). This VA is driven mainly by the VOR that has two components: rotational and translational.

Assessing the Placement of the Cochlear Slim Perimodiolar Electrode Array by Trans Impedance Matrix Analysis: A Temporal Bone Study.

Unlabelled: New cochlear implant (CI) electrode arrays provide softer insertion dynamics; however, due to their high flexibility, the possibilities of fold-overs or intraoperative displacements must be taken into account. The position of each individual electrode can only be determined by using high-resolution computed tomography or cone-beam CT. The trans-impedance matrix test (TIM) is an electrophysiological method based on electric field imaging that can provide images of electrode position and electrode folding.

Differences in Vestibular-Evoked Myogenic Potential Responses by Using Cochlear Implant and Otolith Organ Direct Stimulation.

Several studies have demonstrated the possibility to obtain vestibular potentials elicited with electrical stimulation from cochlear and vestibular implants. The objective of this study is to analyze the vestibular-evoked myogenic potentials (VEMPs) obtained from patients implanted with cochlear and vestibulo-cochlear implant. We compared two groups: in the first group, four cochlear implant (CI) recipients with present acoustic cVEMPs before CI surgery were included.

Chronic Electrical Stimulation of the Otolith Organ: Preliminary Results in Humans with Bilateral Vestibulopathy and Sensorineural Hearing Loss.

Introduction: Bilateral vestibulopathy is an important cause of imbalance that is misdiagnosed. The clinical management of patients with bilateral vestibular loss remains difficult as there is no clear evidence for an effective treatment. In this paper, we try to analyze the effect of chronic electrical stimulation and adaptation to electrical stimulation of the vestibular system in humans when stimulating the otolith organ with a constant pulse train to mitigate imbalance due to bilateral vestibular dysfunction (BVD).

Electrical Vestibular Stimulation in Humans: A Narrative Review.

Background: In patients with bilateral vestibulopathy, the regular treatment options, such as medication, surgery, and/or vestibular rehabilitation, do not always suffice. Therefore, the focus in this field of vestibular research shifted to electrical vestibular stimulation (EVS) and the development of a system capable of artificially restoring the vestibular function. Key Message: Currently, three approaches are being investigated: vestibular co-stimulation with a cochlear implant (CI), EVS with a vestibular implant (VI), and galvanic vestibular stimulation (GVS).

Evaluation of Intracochlear Position of a Slim Modiolar Electrode Array, by Using Different Radiological Analyses.

Introduction: The radiological analysis following a cochlear implantation offers insight into the audiological outcomes of cochlear implant recipients. The wrapping factor (WF) is the most common radiological analysis measuring the modiolar position and depth of insertion of an electrode array. New measurements like the intracochlear position index (ICPI) or the homogeneity factor (HF) can offer more accurate information regarding the electrode's intracochlear position.

Single-sided deafness and cochlear implantation in congenital and acquired hearing loss in children.

Objective: To determine the audiological and clinical results of cochlear implantation in children below the age of 12 years old with congenital and acquired single-sided deafness.

Design: Observational, descriptive, transversal study.

Main Outcome Measures: Speech reception thresholds, Cortical responses, Auditory Lateralization Test and SSQ questionnaire.

Imaging evaluation of electrode placement and effect on electrode discrimination on different cochlear implant electrode arrays.

The aim of the present study is to evaluate the effect of electrode discrimination based on electrode to modiolus distance in different cochlear implant models, using image information to estimate the outcomes after an implantation on electrode discrimination METHODS: A descriptive prospective randomized study performed during 16 months. A psychoacoustic platform was used to evaluate patients' electrode discrimination capabilities of patients. For the acquisition of the images, a cone beam computed tomography was used to assess postcochlear implantation of electrodes' position.

Health-Related Quality of Life in Adult Cochlear Implant Users: A Descriptive Observational Study.

Cochlear implantation has a significant impact on patients' social life, performance of activities, and self-esteem. The objective of this retrospective study was to assess the health-related quality of life of cochlear implant users aged under and over 60 years by a self-report using the Glasgow Health Status Inventory and the Abbreviated Profile of Hearing Aid Benefit. It was observed that quality of life values increased very rapidly straight after implantation regardless of age.

Objective: Prediction of speech recognition (SR) and quality of life (QoL) outcomes after cochlear implantation is one of the most important challenges for otologists. By sifting through very large amounts of data, data mining reveals trends, patterns, and relationships that might otherwise have remained undetected. There are identifiable pre-implantational factors that condition the cochlear implantation outcome.

The relationship between neonatal hyperbilirubinemia and sensorineural hearing loss.

Introduction And Objective: Severe jaundice that requires exchange transfusion has become a relatively rare situation today. About 60% of full term neonates and 80% of premature ones will suffer from jaundice within the first week of life. Hyperbilirubinemia at birth is a risk factor associated with hearing loss that is usually further linked to other factors that might have an effect on hearing synergistically.

Experience in cochlear reimplantation. Descriptive study of a 20-year period.

Introduction And Objectives: The cochlear implant is a surgical procedure that has increased substantially, because the paediatric population is diagnosed and implanted early and because there are increased potential indications. This device has the inherent risk of failure in performance, as dies any active medical device, which is the most common cause of implant removal. Our goal was to understand what the causes that produced removal in our series were, and confirm if these conformed to reality as reviewed in the literature.

Hypothesis: Subjects with normal hearing (NH) experience lower performance in speech understanding in noise when frequency components of speech above 8 kHz are removed.

Background: Previous studies have explored speech perception in noise under various circumstances, but none have been specifically designed to explore the relevance of frequencies above 8 kHz and, more specifically, for the Spanish language.

Methods: Twenty-nine subjects with NH, aged 19 to 55 years, and native speakers of the Spanish language listened to two sets of three disyllabic word lists with background noise.
