Background and Objectives：Identifying cochlear nerve hypoplasia or aplasia is dependent on temporal bone magnetic reso-nance imaging (TBMRI) providing information on the cochlea, internal auditory canal, and the cochlear nerve. The purpose of this study was to review the results of cochlear implantation (CI)TBMRI. Subjects and Method：From April 1999 to April 2005, 321 patients were fited with cochlear implants in our department by two surgeons. The present study focused on four prelingual patients who underwent CI in ears with cochlear nerve hypoplasia or aplasia as sugested by TBMRI. The perceptive and linguistic results were evaluated based on speech perception and production at preimplantation and at 1, 3, 6, 9, 12, and 24 months postimplantation. Results：Pre-operative auditory brainstem responses were ls in 10% and their categories of auditory performance scores were 4 or above. Conclusion：We confirmed cochlear nerve presence in cases of cochlear nerve hypoplasia or aplasia as sugested by TBMRI and made their auditory habilitation posible with cochlear implantation. However, even in cases of cochlear nerve hypoplasia or aplasia suggested by TBMRI, physicians need to confirm coch-lear nerve presence before implantation and to predict the outcome of cochlear implantation.
