Cochlear implantation in different socioeconomic groups - bursting the myth.

OBJECTIVES: Cochlear implantation does wonders for children suffering from severe to profound hearing loss, especially when the child is less than 12 months of age. However, most studies indicate that detection and implantation are done well beyond that age, owing to poor socioeconomic status, parental education, and income. Taking into account The Chief Minister's Comprehensive Health Insurance Scheme in Tamil Nadu, which provides cochlear implantation free of cost, this study aims to describe ages at presentation and nutritional factors among different socioeconomic classes. METHODS: A randomized retrospective comparative study was done between two groups of children based on the socioeconomic status of the family. Group A included children with a parental income of less than Rs. 72,000 and the cost of surgery covered by the Tamil Nadu Chief Minister's Comprehensive Health Insurance Scheme and group B included children with a parental income of more than 72,000 and the cost of surgery covered by the family. Three parameters were considered and compared-the age at presentation to the hospital for diagnosis and management and the weight and hemoglobin. The results were computed, and statistical analysis done. RESULTS: There was a negligible difference between the age at presentation between the two groups with the mean age for children belonging to group A being 2.906563 and the mean age for children belonging to group B being 3.540625. Weight among the two groups showed a significant difference with a p-value of 0.023664 at p < 0.05. The difference in hemoglobin values was found to be insignificant, with mean values being 11.0375 g/dl and 11.7375 g/dl for groups A and B respectively. CONCLUSION: This study has concluded sufficient awareness among different strata of society, despite economical differences, over cochlear implant programs owing to government initiatives of educating people and supporting them with necessary health benefits. Tamil Nadu, as a responsible state of a developing nation, has been proactive in ensuring the accessibility and reach of the health care system in this regard.

Cochlear Implantation in Congenital Long-QT Syndrome: A Comprehensive Study.

OBJECTIVES: Jervell and Lange-Nielsen syndrome is a rare autosomal recessive disease characterized by congenital sensorineural deafness and significant QT interval prolongation. Aims were to study the prevalence of long QT in congenital hearing loss, complications encountered, outcomes by Categories of auditory Performance (CAP) scores and Speech Intelligibility Rating (SIR) scores and to create an algorithm with precautions to be followed in Long QT children. MATERIALS AND METHODS: Study was done at Auditory implant center at a tertiary referral care ENT hospital which includes 41 paediatric patients who were diagnosed to have Long QT during preoperative assessment and underwent cochlear implantation. A standard Protocol was followed in all candidates which includes comprehensive targeted history and investigations, preoperative and intraoperative precautions, and the findings were recorded. RESULTS: Preoperative prophylactic Beta blockers, avoiding sympathetic stimulation and drugs prolonging QT interval with rational use of Magnesium Sulphate and standby of defibrillator were the standard precautions practised. Fatal Arrhythmias were encountered intra-operatively in five patients which was treated with cardiac pacing. Cardiac monitoring was done intraoperatively and during switch-on. Significant improvement in CAP and SIR scores were observed at 3 and 6 months when compared to their base line values. CONCLUSION: With special attention to preoperative evaluation, appropriate intraoperative precautions and monitoring, judicious surgical planning and post surgical follow-up cochlear implantation may be performed safely in patients with JLNS with good postoperative results allowing for improved audition.
