NCT ID: NCT06235073 Completed - Clinical trials for Cochlear Hearing Loss

Robotic and Manual Cochlear Implantation: An Intra-individual Study of Speech Recognition and Electrode Holder Position (ICRobMan)

ICRobMan
Start date: July 1, 2023
Phase:
Study type: Observational

Cochlear implantation (CI) allows rehabilitation for patients with severe to profound hearing impairment. Although the use of a robotic assistant provides technical assistance to the surgeon, the assessment of the impact of its use on auditory outcomes remains uncertain, due to inter-individual variability of preoperative audiometric thresholds and the various possible intrascalar positions of the electrode array. WThe investigators aim to compare the hearing results of patients who underwent bilateral cochlear implantation, one side was performed with manual insertion and the other side with robot-assisted insertion. The electrode array intrascalar positioning and the surgery duration were also studied. This retrospective intra-individual study involved 10 patients who underwent bilateral cochlear implantation. The unique composition of this cohort enabled the investigators to utilize each patient as their own control.

Comparison of Unilateral CI vs. Bimodal Stimulation in Prosodic Perception

Start date: August 30, 2022
Phase:
Study type: Observational

An observational study to determine and assess perception of prosodic information in adults who use bimodal stimulation (cochlear implant plus hearing aid) when using both devices vs. cochlear implant alone.

NCT ID: NCT04815343 Completed - Clinical trials for Cochlear Hearing Loss

Investigation of the Naída CI M90 Sound Processor in Various Acoustic Scenarios

Start date: November 20, 2020
Phase: N/A
Study type: Interventional

In this clinical trial, an un-controlled, repeated measures open design with within-subject comparison will be used to evaluate the effect of Naída Link M90 hearing aid and Naída CI M90 sound processor on sound perception. This design was shown to be successful in previous studies for the evaluation of sound coding strategies. Furthermore, a within-subject comparison decreases the variance in the results allowing for fewer subjects when the population that uses the investigational device is not large in general.

NCT ID: NCT04610216 Completed - Clinical trials for Cochlear Hearing Loss

Investigation of the Automatic Technology on the Naída M Hearing Devices

Start date: October 20, 2020
Phase:
Study type: Observational

In this clinical trial, an un-controlled, repeated measures open design with within-subject comparison will be used to evaluate the effect of the device under investigation on sound perception. This design was shown to be successful in previous studies for the evaluation of sound coding strategies. Furthermore, a within-subject comparison decreases the variance in the results allowing for fewer subjects when the population using the investigational device is not large in general.

NCT ID: NCT04183348 Completed - Hearing Loss Clinical Trials

Evaluation of the Effect of a Visio-Hearing Training Protocol on Spatial Hearing in Subjects With Hearing Loss

EVA
Start date: July 6, 2020
Phase: N/A
Study type: Interventional

We recently developed a new Neuro-immersion system based on virtual reality and 3D (dimension) motion tracking. This tool makes it possible to evaluate and record the spatial localization performance of sounds and to highlight localization deficits in the three dimensions of space in deaf patients. Unfortunately, there is currently no suitable support to compensate for these localization deficits. However, the discomfort felt by the patients is clearly verbalized. Thanks to the new virtual reality system, we are now able to develop a training protocol based on spatial sound localization tasks.

NCT ID: NCT04145661 Completed - Clinical trials for Cochlear Hearing Loss

Non-linear Frequency Compared to Conventional Processing in Patients With and Without Cochlear Dead Regions.

Start date: November 20, 2019
Phase: N/A
Study type: Interventional

The investigators are interested in an additional hearing aid feature called non-linear frequency compression (NLFC). This aims to improve audibility of high frequency sounds by converting them into lower frequencies and has been shown to benefit those with moderate-severe sensorineural hearing loss (SNHL). Cochlear dead regions (DRs) are areas of the inner hearing organ (the cochlea) where there is little or no function and are commonly found in regions responsible for detecting high pitched (frequency) sounds. Not all people with hearing loss have DRs. The investigators would like to determine whether based on the presence or absence of DRs, patients with moderate-severe SNHL perform better or prefer their hearing aids programmed conventionally, or with NLFC activated. To do this, two participant groups will be created based on findings from the threshold equalising noise (TEN) test which identifies cochlear DRs. Two participant groups will be created; one group with DRs and one group without DRs. All participants will receive two hearing aids and will wear these programmed conventionally for ~six weeks and with NLFC activated for ~six weeks in a counterbalanced manner. Following each condition, participants will complete a questionnaire and various speech tests will be performed. This involves participants repeating sentences, words or speech sounds they hear from a speaker in quiet and in the presence of background noise. Individuals' scores will be calculated for each test and their performance when NLFC was activated and deactivated will be compared. This will be analysed alongside the questionnaire data to compare the 'DR' and 'no DR' group in both conditions. Findings may help to determine whether NLFC should be activated for all moderate-severe SNHL patients, or just those with DRs, helping clinicians to optimise hearing aid settings for patients.

NCT ID: NCT04120181 Completed - Infection Clinical Trials

A New Predictor Marker for Cochlear Implants Infection

Start date: May 2014
Phase:
Study type: Observational

Introduction: Surgical site infections associated with the cochlear implant can have serious consequences. Although advances in surgical techniques reduce these complications, it may be necessary to remove a device that works as a last resort as a result of ongoing infection. The removal of these devices, which are very expensive, increases the cost and takes the chance of hearing patients with this device. Therefore, it is very important to identify patients with a tendency to cochlear implant infection before surgery and to prevent these infections from occurring. Neutrophil/ lymphocyte ratio (NLR) and platelet/ lymphocyte ratio (PLR) are indicative of systemic inflammation and have a prognostic value in relation to mortality and morbidity in many diseases. The aim of this study was to identify patients with post-operative implant infection tendency in patients to be implanted with cochlear implant and to plan treatment for possible infections before cochlear implant, to reduce cost by preventing removal of implanted cochlear implant due to infection and to prevent the patient's chance of hearing through the cochlear implant from disappearing due to infection. Methods: In this retrospective study, 13 patients with cochlear implant infection were included. Preoperative NLR was calculated by dividing the neutrophil (NEU) value by the lymphocyte (LYM) value and preoperative PLR was calculated by dividing the NEU value by the LYM value.

NCT ID: NCT04048239 Completed - Clinical trials for Cochlear Hearing Loss

Development of a Robotic Minimally Invasive Pathway for Cochlear Implantation

ROSA-IC
Start date: October 1, 2019
Phase: N/A
Study type: Interventional

Cochlear Implantation is a system developed to restore hearing in people with profound sensorineural hearing loss, whose classical hearing aids are ineffective. Surgery is necessary to insert the internal part into the cochlea and requires milling the mastoid to access the round window. This approach is technically difficult, and is performed under a microscope by an experienced surgeon. The development of a surgical technique that is both safer and less invasive is currently possible thanks to robotics.

NCT ID: NCT03756337 Completed - Clinical trials for Hearing Loss, Sensorineural

Start date: November 1, 2019
Phase: N/A
Study type: Interventional

This study evaluates the benefit of Neuro 1 sound processor upgrade in speech perfomance in adults. Half of participants will be tested with Neuro 1 first and Neuro 2, while the other half will be tested with Neuro 2 first and then Neuro 1.

NCT ID: NCT03500718 Completed - Clinical trials for Cochlear Hearing Loss

Changes in the Threshold of Electrically Evoked Compound Action Potential in Children Following Cochlear Implantation

Start date: February 26, 2018
Phase: N/A
Study type: Interventional

After cochlear implantation, cochlear nerve is stimulated by giving a current over the electrodes placed in the cochlea and the current is measured by electrically evoked Compound Action Potential (ECAP).This ECAP is measured intra operatively, after 4 weeks( at switch on), after 3months and 6 months following cochlear implantation.
