Cohort of Universal Newborn Deafness-gene Screening in Nantong City, China
This study was based on a concurrent newborn genetic and hearing screening program in Nantong city. From January 2016 to December 2020, newborn infants were recruited and received combined screening for free, funded in part by the municipal government and research project foundations. The population-based longitudinal databank for all children with hearing loss in Nantong city commenced in January 2016 and maintained indefinite recruitment and ongoing follow-up.

Unilateral Blindness/ Unilateral Deafness-relation to Neck Pain
Neck pain is a common complaint in the general population affecting 10-15% of the general population. females more than men. Known risk factors are: Trauma, Repetitive lifting of heavy objects at work, driving vibrating vehicles, frequents diving from boards and smoking. No study dealt with the possible role of unilateral loss of vision or hearing as a risk factor for the development of neck pain. Intuitively, one might suspect that unilateral blindness or deafness will lead to a tilted position of the head, in order to cover a better visual/audio field. This position, in time, might lead to the development of neck pain. Our hypothesis is that patients with unilateral blindness/deafness will suffer from neck pain more frequently than the general population.

Optimizing Bilateral and Single-sided-deafness Cochlear Implants for Functioning in Complex Auditory Environments - Part 2
Cochlear implants (CIs) are devices that partially restore hearing for people with severe to profound hearing loss. This research focuses on CI users who use bilaterally implanted devices (two CIs, one on each side) and also "single-sided deafness" (SSD) CI users who use one CI together with good acoustic hearing in their opposite ear. The goal is to measure and understand the impact of large input asymmetries across the two ears. These asymmetries are common in BI-CI listeners and always present in SSD-CI users. Although most CI listeners benefit from a second source of auditory input, this project measures how these asymmetries limit speech understanding and spatial hearing. The long-term goal is countering or compensating for input asymmetries. Electrophysiological measures are used to describe the health of the auditory system. Behavioral measures are used to assess if training improves performance. CT imaging is utilized to describe the placement of the CIs.

Anatomy-Based Cochlear Implant Array Selection for Patients With Single-Sided Deafness
The purpose of the study is to evaluate cochlear implant speech outcomes and subjective benefit for cochlear implant recipients with single-sided deafness using patient-specific, anatomy-based array selection versus standard of care with a fixed array size for all patients. Subjects will prospectively be assigned to receive an Anatomy-Based Electrode (FLEX26, FLEX28, or FLEXSOFT) or the Standard of Care Electrode array (FLEX28). Speech performance and subjective benefit will be evaluated between these two groups.

DEAFNESS SCREENING IN A MEMORY CENTER IN SUBJECTS WITH COGNITIVE DISORDERS
Age-related hearing loss (ARHL), like neurodegenerative diseases, appears insidiously with age. As major public health issues, they are nonetheless under-diagnosed because the presence of one can hinder the objectification of the other. The CogAudio project aims to detect early and in an ambulatory mode in a memory centre a speech perception disorder in noise thanks to the VRB test in patients weakened by cognitive disorders.

Cochlear Implantation in Infants and Toddlers With Single-Sided Deafness
The goal of this clinical trial is to investigate the safety and effectiveness of cochlear implantation in infants and toddlers with single-sided deafness. The main questions it aims to answer are: - Are cochlear implants an effective treatment of single-sided deafness in infants and toddlers? - Are cochlear implants a safe treatment for single-sided deafness in infants and toddlers? Participants will receive a cochlear implant and be followed until they are five years old. During those five years, the investigators will program the device and monitor auditory development. Children will be asked to: - Undergo cochlear implantation - Wear their cochlear implant processor whenever they are awake. - Participate in traditional hearing tests - Participate in traditional hearing testing - Participate in localization testing - Participate in hearing in noise testing - Participate in word recognition testing - Participate in speech, language, and educational evaluations The researchers will compare results to children with typical hearing in both ears and children with single-sided deafness who have not received an implant to observe any differences between the groups.

Correlation MRI - Paraclinical Examination in Sudden Deafness Associated With Vertigo
Acute cochleo-vestibular syndrome or labyrinthitis is characterized clinically by the sudden appearance of a great rotatory vertigo and a unilateral sensorineural hearing loss. In this clinical context, MRI is the examination to eliminate differential diagnoses and to make a positive diagnosis of labyrinthitis (supposedly infectious, immunologic or ischemic). The etiologies described are ischemic, infectious or autoimmune, so the risk factors are very variable (cardiovascular, autoimmune or infectious). Labyrinthitis has been little studied as a clinical entity in its own right. Indeed, studies mainly focus on sudden deafness with subgroups of patients with vertigo. The incidence of sudden deafness is of the order of 5 to 20 per 100,000 people per year but is probably under-diagnosed. The individual and medico-economic consequences are similar to those of hearing loss, with an increased risk of dementia, depression, premature death and an increase in health care consumption.

Evaluation of Rehabilitation Results in the Single-sided Deafness/Asymmetrical Hearing Loss With Cochlear Implantation
Single-sided deafness (SSD) refers to severe to profound sensorineural hearing loss on one side (average pure-tone hearing threshold≥70 dB HL at 0.5, 1, 2, and 4kHz) while the opposite side maintains normal hearing or mild hearing loss (30 dB HL). Asymmetrical hearing loss (AHL) refers to severe to profound sensorineural hearing loss in the bad ear (average pure-tone hearing threshold≥70 dB HL at 0.5, 1, 2, and 4kHz) and mild to moderate hearing loss in the contralateral ear. Moderate hearing loss (30≤mean pure-tone hearing threshold≤55dBHL). It is generally acknowledged that SSD is a particular clinical manifestation of AHL. The number of people who have hearing loss accounts for 5.3% of the total population, with children for 9%. According to the Second National Sampling Survey on Disabled Persons, China has 27.8 million people with hearing disabilities. The incidence of SSD adults in the United States is 7.2%, with 60,000 new cases per year, compared with 7,500 new patients with SSD annually in the UK. The incidence of SSD in neonates is 0.04%-0.34%, and it ranges from 0.1% to 0.5% in children and adolescents. The etiology of congenital SSD is primarily unknown, which is related to genes. Among the causes of acquired SSD, sudden deafness is the most common. Other causes include head trauma, Meniere's disease, labyrinthitis, unilateral acoustic neuroma, middle ear surgery, ototoxic drug exposure, Virus infection, noise-induced deafness, senile deafness, etc. SSD and AHL impede intellectual development and speech development in children and adolescents, which is associated with the side of hearing loss. For example, children with right-sided hearing loss have relatively poor language learning, logical thinking, and divergent thinking. In contrast, children with left-sided hearing loss have weaker analytical, comprehensive and visual memory abilities and relatively poor spatial imagination and visual-motor coordination. In addition, the lack of long-term monaural listening and sound source localization makes SSD children require excessive concentration, which is prone to fatigue and behavioral problems, and their academic performance is lower than that of normal children.

Optimization of Hearing Performance in the Subject Implanted With Profound Asymmetric Deafness
In the past two decades, the selection criteria for cochlear implantation have been greatly relaxed so that about 60-70% of present cochlear implant (CI) candidates have significant residual hearing in their contralateral ear. However, contralateral hearing is often not considered in rehabilitation programs, mainly due to the lack of scientific evidence on the role it may play. The present project aims to better understand the mechanisms of perceptual learning of CI-processed speech after implantation and to develop and test rehabilitation strategies for CI users.
