Genetics: A New Frontier in Otology.

Molecular genetics is a rapidly expanding field with possibilities for novel diagnostic and treatment strategies for otological diseases. Gene therapy, if theory is proven practical, could eliminate disease at the molecular level, thus obviating the need for pharmacologic or surgical treatment. Recent years have seen great advances in our understanding of the molecular genetic basis of many otological disorders.

Syndromic deafness-prevalence, distribution and hearing management protocol in Indian scenario.

Background: The estimated prevalence of Sensory Neural Hearing Loss (SNHL) in patients less than 18 years of age is 6 per 1000. Roughly 50% of cases of congenital SNHL can be linked to a genetic cause, with approximately 30% being syndromic and the remaining 70% being non-syndromic. The term "syndromic" implies the presence of other distinctive clinical features in addition to hearing loss.
