This 3D model illustrates partial external auditory canal atresia, commonly referred to as congenital aural stenosis. Unlike complete atresia, this visualization highlights an abnormally narrowed, yet patent, auditory meatus. By demonstrating the restricted bony and cartilaginous lumen and its anatomical relationship to the tympanic membrane, the model provides an essential clinical reference for understanding conductive hearing loss and assessing the significant risk of canal cholesteatoma formation.
