Still, it seems monsini more study. As the basal turn of the cochlea is intact, high-frequency hearing is generally preserved. Ther reason is that these deformities cannot be diagnosed on CT scan, as CT scans are not able to define abnormalities of the membranous labyrinth. It manifests as a short neck, low hair line and limited neck mobility. This deformity was first described in by Mondini after examining the inner ear of a deaf boy. It includes a complex of features including hemifacial microtia, otomandibar dysostosis, epibulbar lipodermoids, coloboma, and vertebral anomalies that stem from developmental vascular and genetic field aberrations.

There are also some deformities of the membranous labyrinth — as for example the very common Schiebe deformity pars inferior — cochlea and saccule.
A complete labyrinthine and cochlelar aplasia is called the Michel deformity see figure on right, from Strome.

Waardenburg syndrome WS is a largely autosomal dominant disorder characterised by pigmentary anomalies of the skin, hairs, eyes and various defects of other neural crest derived tissues Read and Newton, The embryologic development of the ear is a multi-stage and anatomically complex process involving initally the primitive otocyst. Assays for connexin are commercially available at several laboratories. Barakat Syndrome text courtesy of Dr. Unable to process the form. This syndrome is characterized by hearing disturbances and cataract, branchial cleft fistulae, and preauricular pits.
