A 53-year-old man with bilateral Meniere’s syndrome. Includes a discussion by Dr. Joe Adams on mechanisms involved in fluid-ion homeostasis within the inner ear.
A newborn child with sensorineural hearing loss caused by selective loss of inner hair cells. Includes results of a study on the same topic by Amatuzzi, Liberman and Northrop, and a discussion of the possible role of thiamine deficiency in causing this type of pathology.
A 90-year-old woman with episodic vertigo who had undergone a cochleosacculotomy procedure. Includes a discussion about Meniere’s syndrome, vestibular migraine, and capacity of the cochlea to mount a healing response.

A 77-year-old man with otosclerosis who underwent a stapes mobilization in the right ear and a stapedectomy in the left ear. Both procedures were unsuccessful. Includes a discussion of causes of residual and recurrent conductive hearing loss after stapedectomy.
A 51 year old woman with hearing loss due to Susac’s syndrome. Includes an overview of the syndrome by Dr. John Susac, a description of ophthalmic pathology by Dr. Gerard Lutty, and a description of the otopathology.
A 52-year-old woman with hearing loss due to MELAS syndrome. Includes an overview of mitochondrial disorders by Dr. Katherine Sims, a description of the otopathology, and a discussion of basic and clinical implications.
A 57-year-old man with profound hearing loss due to superficial siderosis; he was treated with a cochlear implant. Includes a review of siderosis with emphasis on its otologic manifestations and a discussion of otopathology after cochlear implantation.
An 82-year-old woman with chronic otitis media. Includes a discussion of pathogenesis of congenital cholesteatoma and histopathology of mastoidectomy with surgical implications.
A 48-year-old man with sensorineural hearing loss occurring in early childhood. Includes a discussion by Prof. Lisbeth Tranebjærg about Wolfram syndrome and genetics of hearing loss in the setting of other neurodegenerative diseases.
A newborn baby boy with bilateral congenital aural atresia. Surgical implications are discussed. Also includes a presentation of a study of the Scala Communis anomaly, with implications for its radiological diagnosis.
A 92-year-old woman with hearing loss and vertigo due to Meniere’s syndrome. Also, includes a study of the histopathology after endolymphatic sac decompression surgery for Meniere’s syndrome.
A 91-year-old woman with bilateral severe hearing loss due to extensive otosclerosis. She had a stapedectomy and labyrinthectomy in one ear. The discussion includes histologic aspects of otosclerosis with clinical and surgical relevance. Also includes a demonstration of various resources featured on the Consortium’s website.
A 34-year-old woman with bilateral hearing loss due to neurofibromatosis type 2 (NF2). Also includes a general discussion of NF2 and determinants of hearing loss in vestibular schwannoma.
A 77-year-old man with history of noise exposure and accelerated presbycusis. Includes a discussion of correlation of audiometric and histopathologic data and recent basic research on long-term effects of noise exposure.
A 100-year-old woman with unoperated acoustic neuroma. Includes a discussion of the histopathology and mechanisms of hearing loss from acoustic neuromas.
A 74-year-old woman with otosclerosis and stapedectomy. Includes a discussion of pathogenesis of otosclerosis.
A 24-year-old man with sensorineural hearing loss due to Wolfram’s syndrome. Includes a discussion of clinical manifestations of the syndrome, and its neuropathology and otopathology.
An 88-year-old woman with sensorineural hearing loss due to strial atrophy. Includes a discussion of phenotypes of strial atrophy, as well as physiology and pathophysiology of the lateral cochlear wall.
A 68-year-old woman with progressive hearing loss due to cochlear atrophy. Includes a discussion of relevance of the pathology to cochlear implantation.
An 88-year-old man with hearing loss due to a temporal bone fracture. Includes a discussion on types of temporal bone fractures, their histopathology, and long-term complications arising from fractures.
