Abstract
Conclusion: Perioperative Minnesota Multiphasic Personality Inventory (MMPI) scores may be beneficial for predicting prognosis of cochlear implantation (CI). A positive attitude for social interaction in particular correlates with a better speech outcome. Proper perioperative psychological management may, therefore, assist in the auditory rehabilitation of CI patients. Objective: To determine the perioperative psychological state of CI patients and its relationship with patient prognosis after CI. Methods: This study prospectively enrolled 29 patients who underwent CI from 2005–2013. The MMPI was administered to assess psychosocial and emotional issues surrounding CI and the Korean version of the Central Institute of Deafness (K-CID) score was used to measure speech perception. Results: CI resulted in a significant improvement on the MMPI Paranoia scale (p = 0.02). Patients with abnormal pre-operative and post-operative MMPI scores also had an earlier onset of deafness, longer duration of deafness, and lower K-CID scores than patients with normal MMPI scores (all p < 0.05). The post-CI K-CID score had a significant negative correlation with the pre-operative MMPI Schizophrenia score (p < 0.01) and significant negative correlations with the post-operative MMPI Paranoia (p = 0.02), Psychasthenia (p = 0.02), Schizophrenia (p = 0.04), Hypomania (p = 0.02) and Social Introversion (p = 0.03) scores.
