Abstract :This study aimed to investigate the value of Constructive Interference In Steady State insert ignore into journalissuearticles values(CISS); magnetic resonance imaging insert ignore into journalissuearticles values(MRI); assessment in evaluating the cranial nerve VIII, and the branches of this nerve for detection of the inner ear abnormalities. Ninety pediatric patients diagnosed with congenital sensorineural hearing loss insert ignore into journalissuearticles values(SNHL); between November 2006 and September 2008 were assessed by 3D-CISS MRI to evaluate the cranial nerve VIII with respect to congenital abnormalities of the inner ear. Of the 90 patients included in the study group, 44 were male insert ignore into journalissuearticles values(48.9%); and 46 were female insert ignore into journalissuearticles values(51.1%); at an age varying from 1 to 16 years old insert ignore into journalissuearticles values(5.97±4.04 years);. The structures of 180 inner ears of 90 pediatric patients were assessed. Pathology was detected in 48 inner ears insert ignore into journalissuearticles values(26.6%); with any of the cochlear, vestibular, semi-circular canal and vestibular aqueduct abnormalities. Among 24 patients insert ignore into journalissuearticles values(26.6%);, Michel deformity insert ignore into journalissuearticles values(1.66%);, cochlear aplasia insert ignore into journalissuearticles values(4.98%);, common cavity deformity insert ignore into journalissuearticles values(2.22%);, cochlear hypoplasia insert ignore into journalissuearticles values(3.33%); and Mondini malformation insert ignore into journalissuearticles values(2.77%); was detected in 3, 9, 4, 6 and 5 inner ears, respectively. Internal auditory canal insert ignore into journalissuearticles values(IAC); assessment revealed dilatation in 11 inner ears, hypoplasia in 6, aplasia in 1 and vestibular aqueduct insert ignore into journalissuearticles values(VAD); dilatation in 9 inner ears. CISS MRI is an effective imaging technique for assessing the inner ear abnormalities, the presence of nerve VIII in patients with congenital sensorineural hearing loss. Thus, we believe CISSMRI imaging  should be performed before any operation in all patients, who may be candidates for cochlear implantation.
