1/5. Delayed endolymphatic hydrops and its relationship to Meniere's disease.Delayed endolymphatic hydrops (EH) can be characterized as having ipsilateral and contralateral types. They are similar in that both have early and late phases of otologic symptoms and that the early phase is a profound hearing loss in one ear. The late phases differ, however, in that the ipsilateral type develops the symptoms of EH (episodic vertigo) in the deaf ear and the contralateral type develops the symptoms of EH (fluctuating hearing loss and/or episodic vertigo) in the hearing ear. In more than half the cases of both types of delayed EH, the profound hearing losses in the early phase are simply discovered to be present in early childhood without a known time of onset. The temporal bones of two patients with contralateral delayed EH show pathologic changes in the deaf ears that are similar to those known to occur in mumps and measles labyrinthitis, whereas the pathologic changes in the hearing ears are similar to those known to occur in Meniere's disease. These observations support the proposition that Meniere's disease may occur as a delayed sequela of inner ear damage sustained during an attack of subclinical viral labyrinthitis occurring in childhood.- - - - - - - - - - ranking = 1keywords = labyrinthitis (Clic here for more details about this article) |
2/5. Idiopathic sudden sensorineural hearing loss and postnatal viral labyrinthitis: a statistical comparison of temporal bone findings.Although the cause of idiopathic sudden sensorineural hearing loss remains uncertain, a viral origin has been suggested in many cases on the basis of anamnestic microbiologic and pathologic data. Twenty-two temporal bone specimens from 18 patients who during life suffered a sudden partial or complete sensorineural hearing loss were studied. On the basis of clinical data, these cases were assigned to one of three diagnostic categories, and the temporal bones were studied by light microscopy and serial section analysis. The implications of the histopathologic findings for the pathogenesis of idiopathic sudden sensorineural hearing loss are discussed.- - - - - - - - - - ranking = 2keywords = labyrinthitis (Clic here for more details about this article) |
3/5. Viral labyrinthitis: early pathology in the human.The histologic findings in the temporal bones of three patients who died from viral encephalopathy are presented. pathology was restricted to the scala media, vestibular labyrinth, and internal auditory canal and was considered to be expressions of viral labyrinthitis. The changes were different degrees of degeneration of the organ of corti, early encapsulation of the tectorial membrane, degeneration of the stria vascularis, and round cell infiltration of the modiolus and contents of the internal auditory canal. A new finding in the organ of corti and early stages of cystic degeneration of the stria vascularis are documented. In all cases, the saccule was degenerated with sloughing of the otolithic membrane and vestibular labyrinth was involved in varying degrees.- - - - - - - - - - ranking = 2.5keywords = labyrinthitis (Clic here for more details about this article) |
4/5. Psychological effects of symptoms associated with labyrinthitis. a case study.The psychological effects of postviral labyrinthitis in a patient who had been undergoing intensive psychotherapy are reported. The mildness of the physiological symptome was in contrast to the magnitude of the psychological consequences. The general psychological effects of illness on the patient are differentiated from the specific psychological correlates of vertiginous symptoms. The factors that contributed to the psychological effects and the psychological impact of these symptoms are discussed. There is a special potency to the cited effects in patients with specific personality characteristics.- - - - - - - - - - ranking = 2.5keywords = labyrinthitis (Clic here for more details about this article) |
5/5. Dizzy patients: the varieties of vertigo.Some vertigo results from acute viral labyrinthitis or a cerebrovascular event; many cases are due to loose particulate matter within the semicircular canals. In the vast majority of patients, a careful history and appropriate clinical tests will suffice to identify the cause of the vertigo--and with benign paroxysmal positional vertigo, a simple clinical maneuver can also provide a cure.- - - - - - - - - - ranking = 0.5keywords = labyrinthitis (Clic here for more details about this article) |
