Imaging in a Rare Case of Unilateral External and Middle Ear Anomalies Associated with Inner Ear Malformation
External ear malformations are commonly associated with middle ear malformations due to their closely related embryogenesis. Inner ear anomalies are less consistently seen due to their independent development. Cross-sectional imaging has come to play a critical role in the workup of congenital deafness in the pediatric age group. To optimize speech and language development, early diagnosis and treatment are very crucial. Identification of these anomalies is additionally important when operative intervention is being planned because they may complicate or perhaps preclude the surgery.
