PROBLEM The advantages of bilateral, simultaneous cochlear implantation include: the possibility to pre-empt cochlear calcification following meningitis; reduction of the intervention to only one procedure, general anaesthetic and course of clinical care (with obvious benefits for the patient); and greater cost-effectiveness. The disadvantages of such a procedure include: doubling the risk of a...

IMPORTANCE This study reviewed whether advanced age should be a consideration when revision cochlear implantation is warranted. OBJECTIVE To examine whether age at revision cochlear implantation is related to postrevision speech perception performance. DESIGN, SETTING, AND PARTICIPANTS A retrospective analysis was performed in an academic tertiary care center. Participants included 14 young...

The benefit of cochlear implantation crucially depends on the ability of the brain to learn to classify neural activity evoked by the cochlear implant. Brain plasticity is a complex property with massive developmental changes after birth. The present paper reviews the experimental work on auditory plasticity and focuses on the plasticity required for adaptation to cochlear implant stimulation. ...

Objectives: The aim of present study was evaluation of saccule function in cochlear implant candidates with severe to profound sensory neural hearing loss Before and after cochlear implantation Methods: In this study 35 cochlear implant (CI) candidates with bilateral severe to profound sensory neural hearing loss before and about 30 days after cochlear implant and 20 normal-hearing cases as ...

Abstract Purpose of Review This review will highlight recent outcome-based evidence guiding decision making for cochlear implantation in advanced otosclerosis, related complications, and technical surgical considerations otosclerosis the obstructed cochlea. Recent Findings Cochlear results consistent, excellent auditory outcomes with improvement both objective speech recognition scores subjecti...

Cochlear implantation may cause a detrimental effect on vestibular function and residual hearing. A significant number of patients with cochlear implant present vertigo. There are several mechanisms for dizziness following implantations. The causes be surgical trauma, disruption normal physiology, or ensuing endolymphatic hydrops. Vibratory trauma affecting the cochlea during cochleostomy plays...

One of surgical complications in cochlear implantation is the necrosis of the skin flap above the receiver-stimulator coil. We present a case of 55-year-old woman who underwent cochlear implantation and developed a bluish skin necrosis due to bone marking. The planned position for the receiver-stimulator was marked using methylene blue through skin to bone. She did not undergo skin flap thinnin...

Introduction Current data show that binaural hearing is superior to unilateral hearing, specifically in the understanding of speech in noisy environments. Furthermore, unilateral hearing reduce onés ability to localize sound. Objectives This study provides a systematic review of recent studies to evaluate the outcomes of cochlear implantation in patients with single-sided deafness (SSD) with re...

The frequency of three mitochondrial point mutations, 1555A-->G, 3243A-->G, and 7445A-->G, known to be associated with hearing impairment, was examined using restriction fragment length polymorphism (RFLP) analysis in two Japanese groups: (1) 319 unrelated SNHL outpatients (including 21 with aminoglycoside antibiotic injection history), and (2) 140 cochlear implantation patients (including 22 w...

OBJECTIVE To report a successful case of cochlear implantation and auditory training for the improvement of sound localization in a patient with single-sided deafness. STUDY DESIGN Case report and literature review. SETTING Tertiary referral otology practice. PATIENT Fifty-seven-year-old man receiving cochlear implantation after 8 years of unilateral sensorineural hearing loss. INTERVEN...
