Both groups were matched based on gender and age.</p> <p style="text-align: justify;"><strong>Results:</strong> VEMP responses were absent bilaterally in 10 out of 35 patients. 4 patients were excluded from the study because they did not receive CI during present study. From 21 remaining patients, 5 cases lost VEMP responses in their implanted ear after surgery. In control group, VEMP responses were present bilaterally.</p> <p style="text-align: justify;"><strong>Discussion:</strong> The results of present study indicate that saccule dysfunction in CI candidates is extremely probable and this is possible that saccule get impaired after CI.</p> Cochlear implant, Sensory neural hearing loss, Saccule, VEMPs 24 27 http://irj.uswr.ac.ir/browse.php?a_code=A-10-414-1&slc_lang=en&sid=1 Yones Lotfi yones1333@gmail.com No University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.
