Eligibility

Age
18 Years to 65 Years

Inclusion criteria

Inclusion criteria: Patients with post lingual deafness; bilateral sensorineural hearing loss severe to profound; no benefit with the use of hearing aids or those with indices below 50% in sentence recognition using the best possible bilateral fitting tests.

Exclusion criteria

Exclusion criteria: patients with obliteration of the tympanic cavity; patients with indication for middle fossa surgical approach; orthopedic, neurological or visual disorders that could interfere with the results of the computerized dynamic posturography

Design outcomes

Primary

MeasureTime frame
The absence of post-caloric response in preoperative evaluation, contacted through caloric and rotatory chair test, resulted in a worse prognosis in the evolution of body balance over 1 year. Having been considered a significance level of 5% (? = 0.05) comparing pre and post IC evaluations.—

Secondary

MeasureTime frame
Improvement in balance followed the time frame proposed in the literature for central compensation mechanisms and it was verified by computerized dynamic posturography. When considering the condition 5 of CDP 5 we found a statistically significant numerical increase between day zero and day 120 (p = 0.013), 180 (p = 0.006) and 365 (p = 0.004). ;Cases of dizziness reported before CI and confirmed by clinical evaluation at the end of the study ameliorated in 11 patients (84.6%), worsened in 1 (7.7%)and remained unchanged in 1 (7.7%).—
