WebbInner ear with vestibular schwannoma (tumor) A vestibular schwannoma (also known as acoustic neuroma, acoustic neurinoma, or acoustic neurilemoma) is a benign, usually slow-growing tumor that develops from the balance and hearing nerves supplying the inner ear. Source: NIH/NIDCD Webb1 okt. 2002 · The inner ear develops from the otic placode (a) an ectodermal thickening that invaginates to form the otic pit (b) which in turns pinches off from the ectoderm to form the otic vesicle (c). The different sensory organs are derived from a common pro-sensory patch (black) in the ventromedial wall of the otocyst (c). WebbObjective: To investigate the histopathology of inner ear malformations (IEMs) in order to explain their pathophysiology. Method: Light microscopy was used to study 33 specimens exhibiting various IEMs in the collection of the Otopathology Laboratory at Harvard University's Massachusetts Eye and Ear Infirmary. clive warren butchers
