Abstract
Objective:To evaluate the auditory functions and progress of speech development in children with and without cochlear anomalies who underwent cochlear implantation due to prelingual profound sensorineural hearing loss (SNHL).Methods:This study was conducted at Gaziantep University Faculty of Medicine Ear-Nose-Throat Department, between October 2006 and December 2007. A total of 69 children (aged 6 to 24 months) diagnosed with profound SNHL were included. Patients were divided into two groups with respect to the presence of inner ear anomalies: Group-1 consisted of 41 children without inner ear anomaly, whereas Group-2 was composed of 28 patients with inner ear anomalies. The auditory performance was assessed using Listening Progress Profile Test (LPPT) and Monosyllabic Trochee Polysyllabic Test (MTP), the subsections of Evaluation of Auditory Responses to Speech (EARS) test battery.Results:Preoperative LPPT scores were 5 (12%) in both groups. Mean LPPT values after fitting in Group-1 and Group-2 on 1st, 3rd and 6th months were 18.5 (44.1%) and 19 (45.6%); 27 (64.2%) and 28 (67.3%); 31 (75%) and 34 (83%), respectively. Postoperatively, MTP scores in Group-1 and Group-2 were 7.5 (62%) and 7.7 (64%) for 3-words set; 10.4 (58%) and 10.6 (59%) for 6-words set; 14.3 (60%) and 14 (59%) for 12-words set, respectively. The rate of stimulation for electrodes was 1345 q/u (quick/unit) in Group-1 and 1310 q/u in Group-2. No statistically significant difference was detected between groups for variables under investigation.Conclusion:Cochlear implantation is an effective treatment in children with prelingual profound SNHL. Auditory performance and advancement of speech are similar for children with and without inner ear anomalies.

Hearing loss is an important disability in our country and over the globe
A total of 69 cases with prelingual bilateral profound sensorineural hearing loss (SNHL) or developed within the first two years of life were included in the study
Patients who did not benefit from hearing aids, and were prospective cochlear implant candidates, underwent thin-slice axial and coronal computed tomographic (CT) and temporal magnetic resonance imaging (MRI) techniques (Fig.1-4)
Summary
Hearing loss is an important disability in our country and over the globe. This problem preventsCorrespondence: October 16, 2017 October 27, 2017 March 21, 2018 March 22, 2018 social harmony and leads to the emergence of individual and social problems. Hearing loss is an important disability in our country and over the globe. Vigorous efforts have been made to help these patients to gain their hearing abilities, and to develop speech. Cochlear implant system which has been successfully applied all over the world can recover hearing ability of these patients.[1,2] For a successful cochlear implant surgery, anatomical structures of the inner ear and auditory nerve should be intact. Despite the presence of the structures of the inner ear, they may not have a typical appearance. Imaging modalities detect malformations of the inner ear structures of the children born with hearing loss.[3,4] Using
