Overview
Brief Summary
The cochlear implant is an electrical hearing aid that restores the perception of surrounding sounds and speech intelligibility in profoundly deaf patients. During surgery, the labyrinthine break necessary for insertion into the cochlea of the implantable part may cause a malfunction of the vestibular system which can induce dizziness, balance and perception (of the gravitational vertical) disorders. Vestibular compensation and new sonic interactions could alter the balance control and the visual and postural spatial orientation perceptions.
The usual treatment includes the monitoring of the patient's quality of life, of the vestibular function and of hearing. This study adds an assessment of spatial orientation and of posture.

Eligibility Criteria
Inclusion Criteria
- •Profound deaf patients who are scheduled for a cochlear implantation
- •Patients gave their written informed consent
- •Patients are affiliated to the french social welfare
Exclusion Criteria
- •Disorders from the motor and/or somesthetic systems (especially the lower limbs)
- •Contraindications to the scheduled functional assessments
Outcomes
Primary Outcomes
Change from baseline in postural perception of the gravitational vertical
Time Frame: One year
The same assessment will be performed 4 times (3 days before surgery, 3 days, 45 days, and one year after surgery). The measure is the average difference between the gravitational vertical and the tilt of the platform (in degree) over 20 trials.
Secondary Outcomes
- Change from baseline in dynamic balance control(One year)
- Change from baseline in vestibular function(One year)
- Change from baseline in dizziness(One year)
- Change from baseline in quiet standing within a specific sound environment(One year)
- Change from baseline in speech recognition(One year)
- Change from baseline in quality of life(One year)
- Change from baseline in visual perception of the gravitational vertical(One year)
