The Nucleus Straight Research Array (SRA) cochlear implant has a new 25-mm electrode carrier designed to minimize insertion trauma, in particular allowing easy via the round window. aims of this study were measure preoperative postoperative benefit terms speech recognition quiet and noise three groups patients (electrical complement, EC; electrical stimulation, ES; electro-acoustic EAS) with varying levels low-frequency hearing, evaluate preservation residual hearing after implantation SRA...

In Brief Objectives: To measure benefit in terms of speech recognition quiet and noise, conservation residual hearing three groups subjects implanted with the Nucleus Straight Research Array cochlear implant. This device incorporates Slim electrode carrier designed to be easier insert into cochlea via round window while potentially minimizing insertion trauma. Design: The study was prospective, sequential enrolment within-subject repeated measures; 35 were 15 84 years age varying levels...

Abstract Objective: In cochlear implantation, there are two crucial factors promoting hearing preservation: an atraumatic surgical approach and selection of electrode that does not damage structures. This study aimed to evaluate preservation in children implanted with the Nucleus Slim Straight (CI422) electrode. Methods: Nineteen aged 6–18 years, partial deafness, were using 6-step Skarzynski procedure. Electrode insertion depth was 20–25 mm. Hearing status assessed pure tone audiometry...

This paper explores the pace and direction of technological development by using a technology upgrade conceptual measurement framework. approach is applied to sample 164 economies worldwide between 2002 2019. Within framework upgrading, focuses on digitalisation “greening” as its two significant structural features. We explore their relationship with different components upgrading indicators macroeconomic productivity. have adopted longitudinal fixed effects regression method control for...

Background To maximise the success of cochlear implantation, optimal placement electrodes inside cochlea is required. Hearing preservation also means that intracochlear spaces must be approached in a way avoids traumatising inner ear structures. Material and Methods In order to examine this issue literature search was performed targeting articles on surgical techniques used partial deafness implantation. The aim evaluate advantages shortcomings each technique. Results implantation two main...

Because of vast variability cochlear implantation outcomes in prelingual deafness treatment, identification good and poor performers remains a challenging task. To address this issue, we investigated genetic variants matrix metalloproteinase 9 (MMP9) brain-derived neurotrophic factor (BDNF) plasma levels MMP-9, BDNF, pro-BDNF that have all been implicated neuroplasticity after sensory deprivation the auditory pathway. We recruited cohort prelingually deaf children, implanted before age 2,...

Due to the constant development of technology and medicine, eligibility criteria for cochlear implantation (CI) are undergoing gradual expansion.To provide long-term hearing preservation (HP) results partial deafness treatment (PDT) a group adults using electro-natural stimulation (ENS).We examined database medical records patients who underwent CI in single ENT center. We identified 12 (3 men 9 women) fitted PDT-ENS classification. To calculate HP, we used -HEARRING consensus conducted...

Genetic biomarkers of neuroplasticity in deaf children treated with cochlear implantation (CI) might facilitate their clinical management, especially giving them better chances developing proficient spoken language. We investigated whether carrying certain variants the genes encoding matrix metalloproteinase MMP9 and neurotrophin brain-derived neurotrophic factor ( BDNF), involved synaptic plasticity, can be taken as prognostic markers how well auditory skills acquired. Association analysis...

Background Hearing screening is an important part of prevention. It allows early detection hearing disorders, allowing treatment to begin and eliminating or minimizing negative consequences. Children with impairment often experience delayed speech development cognitive abilities, which can result in learning disabilities reduce school progress. Since 1999, the Institute Physiology Pathology Poland has provided a program for school-aged children country. The main aim especially starting...

Hearing preservation surgery requires specially a traumatic technique. Having some preoperative anatomical data of the size patient's cochlea surgeon can design his or her insertion depth. In study we have evaluated relation between hearing rate and angular depth estimated intraoperatively postoperatively having measured angle from radiological assessment calculations given by Escude. There has not been no statistically significant difference angle, either calculated post-operatively, in...

Hearing impairment is a condition, which especially severely affects children, having an extremely intense impact on the child's development. Development of spoken language, one modes o...

Abstract Purpose If before cochlear implantation it was possible to assay biomarkers of neuroplasticity, we might be able identify those children with congenital deafness who, later on, were at risk poor speech and language rehabilitation outcomes. Methods A group 40 aged up 2 years DFNB1-related observed in this prospective cohort study over three follow-up intervals (0, 8, 18 months) after implant (CI) activation. Children assessed for auditory development using the LittlEARS Questionnaire...

Human Papilloma Virus has a strong relation to oropharyngeal mucosa and is considered be responsible for wide range of upper respiratory tract pathologies, like laryngeal papilloma. There's hypothesis, that it plays significant role in middle ear chronic inflammations neoplasm's. The examination was carried on group 53 patients, 39 which suffering from granulation tissue otitis media, 7-cholesteatomatous 6 – malignant neoplasm, 1 and/or external benign neoplasm. control consisted 5 patients...

Objective Chronic obstructive inflammation of the external ear canal after different kinds surgeries often leads to restenosis. There are approaches treatment such cases, and one solution is a middle implant. Here we analyze efficacy using Vibrant Soundbridge implant with new incus short process (SP) coupler in this type case. Material Methods We present case study 29-year old patient bilateral mixed hearing loss caused by canals. He had undergone meatoplasty very short-lived improvement....

There is a need for regular surveillance of the hearing children, no matter what their age. Screening school children can be done quickly and cheaply using teleaudiology. The primary aim this study was to identify who showed suspected impairment from rural areas Kujawsko-Pomorskie region refer them further audiological testing. A secondary estimate prevalence loss in those children.There were 4754 made up 1840 aged 6-7 years old 2914 12-13 old. Pure-tone air conduction thresholds obtained at...

Undiagnosed hearing deficits hamper a child’s ability to learn. Hearing screening in school aged children helps detect educationally significant loss and prevents negative impacts on academic achievement. The main purpose of this study was improve early detection assess the incidence disorders first-graders from rural areas small towns Małopolskie Voivodeship Poland. There were 5029 6–7 years. thresholds measured over frequency range 0.5–8 kHz. A result considered positive (abnormal) if...

Congenitally deaf children who undergo cochlear implantation before 1 year of age develop their auditory skills faster than are implanted later. In this longitudinal study, a cohort 59 were divided into two subgroups according to ages at implantation-below or above old-and the plasma levels matrix metalloproteinase-9 (MMP-9), brain-derived neurotrophic factor (BDNF), and pro-BDNF measured 0, 8, 18 months after implant activation, while development was simultaneously evaluated using LittlEARs...
