Classification of cochlear anomalies
The cochlea is prone to a variety of congenital anomalies, depending on the exact time at which an insult occurs during embryogenesis. Terminology is often used imprecisely leading to confusion not only among clinicians but also in the literature.
A classification first propsed in 1987 by Jackler et al 2 has become widely accepted (with various modification), which divides congenital cochlear anomalies according to the timing of developmental arrest.
Conveniently starting from the 3rd week of gestation, an insult during each subsequent week results in a distinct inner ear abnormality.
