Approach to Cochlear Implantation in Patients With Ventriculoperitoneal Shunts.

To evaluate the safety and outcomes of cochlear implantation (CI) in patients with ventriculoperitoneal (VP) shunts to inform clinical practice.... Historical cohort study.... Tertiary referral centers.... A multi-institutional historical cohort of patients with VP shunts and CI was identified and analyzed.... A total of 46 patients (median age 8 years [interquratile range, IQR: 2-46]) with VP shunts and CI were identified. Of these, 41 (89%) patients had a VP shunt prior to CI. Based on institutional prefe... CI can be performed at low risk, either contralateral or ipsilateral, to a VP shunt, and does not mandate shunt revision in most cases. Additional considerations regarding CI receiver-stimulator place...

Third-party disability in cochlear implant users.

To date, auditory rehabilitation mainly focuses on the person with hearing impairment (PHI). This study aimed to analyse the burden of hearing loss on significant others (SOs), and to explore the impa... Third-party disability (SOS-HEAR) and quality of life (Nijmegen Cochlear Implant Questionnaire) were evaluated in 41 PHI scheduled for CI surgery and their close partners pre- and 6-month post-implant... Hearing loss imposes a burden on SOs, particularly in relation to changes in communication and socialisation. Third-party disability was higher in SOs of PHI with lower educational background (... Audiological rehabilitation should expand to include SOs in the rehabilitation process, as the burden experienced by SOs might persist even after CI....

How useful is electrocardiography in children with cochlear implantation?

Hearing loss is an important health problem in children and cochlear implantation is used in its treatment. In addition, in children with hearing loss, accompanying renal, neurological, structural and... The data were obtained from the medical records of our hospital, which is a tertiary referral cochlear implant center. All children who had cochlear implantation surgery due to sensorineural hearing l... Sixty children (15 girls and 45 boys) with a mean age of 6.5 years were analyzed. Children with a history of heart disease were excluded. In cardiac examinations, five (8.3%) had systolic murmur, four... This study demonstrates the need for electrocardiography and cardiac examinations in children undergoing cochlear implantation for hearing loss. These cases should be evaluated especially in terms of ...

Cochlear implants: Visual evoked potentials study.

Cochlear implants (CIs) are a successful alternative in cases with severe-to-profound HL. In these individuals, visual cross-modal re-organization can occur because of hearing loss where the visual co... This work is designed to study visual evoked potentials (VEPs) in children fitted with CIs in comparison to normal hearing children.... This work included 2 groups of children: Group I included 20 normal hearing children and study group included 25 children fitted with unilateral CIs. All cases were subjected to Thorough otological hi... Both groups showed no significant difference as regard age or sex. And both had normal ophthalmic examinations. Children of the study groups showed satisfactory aided response. As regard pVEPs, the st... This study showed that deafness could induced cortical organization in the visual cortex and not limited to the auditory cortex only....

Factors Affecting Early and Late Cochlear Implantation.

This study aimed to describe the factors affecting early and late cochlear implantation.... A total of 159 patients from the Hospital Canselor Tuanku Muhriz (HCTM) Cochlear Implant Programme were recruited in this retrospective cross-sectional study. All paediatric Cochlear Implant (CI) reci... A total of 83 (52%) patients were female. Chinese race constituted most of the patients, which was 90/159 (57%). The majority were from middle-income families (M40); 89 (56%). The most common aetiolog... UNHS was a significant factor contributing to early and late implantation.

Impedance development after implantation of hybrid-L24 cochlear implant electrodes.

Shorter and thinner electrodes were developed for preserving residual hearing after cochlear implantation by minimising trauma. As trauma is regarded as one of the causes of fibrous tissue formation a...

All 137 adult patients received a Hybrid-L electrode and had to be implanted for at least 1 year.... On average impedances increased to 13 kOhm before first fitting and dropped to 5-7 kOhm under electrical stimulation with lower values measured on apical contacts. Mean values remained stable over yea... Despite smaller contacts, impedance values after start of electrical stimulation were comparable to published values of Contour electrodes. This might suggest less tissue growth with the Hybrid-L elec...
