| Abstract | OBJECTIVES: To assess the effect of an intraoperative perilymph fluid gusher during cochlear implantation on speech perception abilities in pediatric patients with labyrinthine anomalies. SETTING: Tertiary care academic referral center. METHODS: Seventy subjects with labyrinthine malformations who received a cochlear implant were identified in our pediatric cochlear implant database. In 30 cases, an intraoperative perilymph fluid gusher was encountered during surgery. Fifteen children with GJB2 positive hereditary hearing loss served as controls. Multiple speech perception measures were obtained with the cochlear implant. The best score for each subject over time was determined as a speech reception index in quiet. This index was compared among groups and malformation types. RESULTS: The speech reception index in quiet demonstrated overall good performance scores of cochlear implantation in children with incomplete partitioning/enlarged vestibular aqueduct type malformations. Children with hypoplastic malformations, on the other hand, showed variable outcomes with many children demonstrating only limited long-term speech discrimination abilities. The presence or absence of a perilymph gusher did not significantly influence results after cochlear implantation. CONCLUSION: This report documents the variable outcomes of pediatric cochlear implantation in children with inner ear malformations. More importantly, anatomic parameters, such as the classification of the anomaly and the presence of a viable cochlear nerve, seem to influence performance measures substantially. The presence of a perilymph gusher did not influence outcomes in both hypoplastic and incomplete partitioning/enlarged vestibular aqueduct type malformations. LEVEL OF EVIDENCE: 2b Individual retrospective cohort study. |

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.
