Inner ear dysplasia in sporadic lacrimo-auriculo-dento-digital syndrome. A case report and review of the literature.

The lacrimo-auriculo-dento-digital (LADD) syndrome is a rare inherited disorder affecting the lacrimal, auricular, salivary, and osseous system. Only very limited data on LADD associated petrous bone lesions are available up to now. We describe a young girl suffering from the LADD syndrome with sensorineural hearing loss and inner ear dysplasia. This case suggests, that inner ear dysplasia might be a more common feature of the LADD syndrome than has been assumed so far. Copyright 2002 S. Karger AG, Basel
