" 08/01/2004 - "Our study conducted on 39 children with pre-lingual bilateral sensorineural autosomal recessive deafness showed as follows: (I) from a molecular perspective: an incidence of 41% in the cases studied of mutations in the encoding of the connexin 26 gene; a prevalence in our case study of the 35delG mutation (69%). " 09/01/2003 - "After taking into account other factors which are known to affect language development and speech perception in children with impaired hearing, no significant differences were found between the 15 children where connexin 26 was known to be the cause of deafness and the other 37 children in the study." 10/01/2001 - "[Study of a mutation in connexin 26 gene associated with congenital sensorineural deafness]."

Therapies and Procedures

1.	Cochlear Implantation 02/01/2015 - "Cochlear implantation is rapidly gaining acceptance as the most effective treatment for adult patients with unilateral deafness. " 08/01/2004 - "Cochlear implantation was least effective when the preoperative audiological status of the better-hearing ear was good and the duration of profound deafness of the implanted ear was long. " 01/01/2011 - "The results in these patients suggest that cochlear implantation improves hearing abilities in people with single-sided deafness and is superior to the alternative treatment options. " 01/01/2006 - "A major source of controversy between Deaf people and those who support a "social/cultural" view of Deafness as "a life to be lived" and those who see deafness within a "medical model" as a "condition to be cured" has been over the cochlear implantation of young deaf children. " 01/01/1998 - "We concluded that the results of postlingual patients after cochlear implantation showed clear benefits of these devices in profound bilateral deafness, better results with the SPEAK coding strategy than with MPEAK and constant improvement in results, even after the first year of surgery."
2.	Cochlear Implants (Cochlear Implant) 06/01/2012 - "Cochlear implants are the best treatment for congenital profound deafness. " 10/01/2012 - "Recent research in genetics indicates that the cause of deafness in individuals with Usher type 1 (USH1) could be beneficial for the outcome with cochlear implants (CI). " 01/01/2014 - "Since their introduction more than 30 years ago, cochlear implants have improved their performance to the extent that are now considered to be standard of care in the treatment of children with severe to profound deafness. " 01/01/2009 - "PCR has proved to be a very useful tool in order to investigate infectious causes of deafness even for more than one virus type at a time and in a limited quantity of sample, such as the small volume of endolabyrinthine liquid collected from children during cochlear implant surgery." 11/01/2012 - "The cochlear implant (CI) is the first effective treatment for deafness and severe losses in hearing. "
3.	Hearing Aids (Hearing Aid) 08/01/1996 - "This study has shown that in this preselected group of children with persistent OME and the predominant symptom of deafness, a hearing aid was an effective treatment for their deafness with high acceptance and compliance." 04/01/2009 - "The aim was to examine short- and long-term efficacy of the bone-anchored hearing aid (BAHA) on adults with single-sided deafness. " 04/01/2009 - "Efficacy of the bone-anchored hearing aid for single-sided deafness." 03/01/2003 - "Because age at implantation negatively correlates with improved speech perception after implantation, congenitally affected children with profound deafness (if they cannot obtain enough benefit from hearing aids) should receive implants as early as possible." 09/01/2015 - "No factors that were evaluated in this study, including gender, age, etiology of deafness, duration of deafness, time between implant insertion, and the preoperative hearing aid status, were correlated with stability duration in either stability assessment method. "
4.	Electrodes (Electrode) 03/01/2007 - "In agreement with the notion that EABR maturation follows an apex-to-base gradient as described for ABR, we observed that wave V latencies were longer for the basal than the apical end of the implant electrode array and remained so throughout the study period, whatever the time of onset of deafness. " 01/01/1980 - "[Trials of treatment of perceptive deafness by implantation of electrodes into the cochlea (author's transl)]." 03/01/2015 - "In postmeningitis deafness, initial choice of electrode array is of utmost importance.

" 02/01/2014 - "Positive preconditions are short ipsilateral and short bilateral deafness periods and high number of auditory electrodes. "
5.	Prostheses and Implants (Prosthesis) 01/01/1993 - "However it must be only applied to total deafness which fail to show an improvement with conventional acoustic prostheses.
