Mondini dysplasia
Mondini dysplasia, also known as Mondini malformation and Mondini defect, is an abnormality in the inner ear that can be the cause of hearing loss. A person with Mondini dysplasia has a cochlea that is incomplete. A normal cochlea has two and a half turns, a cochlea with Mondini dysplasia has two, one and a half, one, or no turns. This results in gradual or even sudden hearing loss that may be profound."case history". This type of malformation has been described as a flattened cochlea with development only of the basal coil. Instead of two and one-half turns in the bony cochlea, there may be only one and one-half turns, with the middle and apical turns occupying a common space or cloaca. The agenesis is rarely symmetrical, but both ears always show some degree of malformation. The vestibular structures and their associated neural elements may be similarly underdeveloped. There appears to have been an interruption in the development of the cochlea at the stage in which it is represented by a short, curved tube. Vestibular structures may be recognizable in some cases; in others there is no membranous labyrinth. Occasionally some sensory epithelium may be present; this implies the possibility of function. An enlarged endolymphatic duct and sac and a deficient utriculoendolymphatic valve are commonly found associated with collapse of Reissner’s membrane or an absence of endolymphatic hydrops. Lesions of the end-organ of Corti may be present or absent. The stria vascularis and spiral ligament are often normal. Mondini’s deformity may be associated with an absence of the oval and round windows along with other aplastic lesions of the middle ear.²
