| Abstract | OBJECTIVE: We aimed to investigate the origin of hearing loss with relevance to auditory brainstem responses and otoacoustic emissions in patients with Duane's retraction syndrome (DRS). MATERIALS AND METHODS: 17 patients with DRS were included in the study. 14 patients were diagnosed as DRS type 1 and the remaining three as type 3. The control group consisted of nine healthy subjects. Pure tone audiogram, auditory brainstem response, as well as distortion product otoacoustic emissions were recorded in all the patients and the controls. RESULTS: Among the 17 patients with DRS, 15 demonstrated normal hearing according to pure tone audiogram. One patient with DRS had profound sensorineural hearing loss with a pure tone average of 110 dB, and one patient had moderate sensorineural hearing loss with a pure tone average of 60 dB. Auditory brainstem response latencies of the waves I, III and V, and interwave latencies were calculated in 15 patients with DRS and were compared with the control group. There was statistically significant increase in wave I latency of left ear in the DRS group compared to the controls (P<0.05). Amplitudes of distortion product otoacoustic emissions were also recorded at frequencies of 2, 3, 4, 6, and 8 kHz in both groups and the comparison of the DRS patients and controls revealed no statistically significant difference. CONCLUSIONS: We recommend auditory examinations be undertaken in patients with DRS by auditory brainstem response tests, as well as distortion product otoacoustic emissions, whereas all patients with normal results should be followed-up for future hearing loss. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
