Acute sensorineural hearing loss, mostly unilateral and reversible, is a well-known complication to mumps. Secondary endolymphatic hydrops, Ménière's syndrome, has rarely been associated with a previous mumps infection. This paper presents the case report of a woman who experienced unilateral
The histologic features of the endolymphatic sac and duct in 23 serially sectioned temporal bones with idiopathic or secondary endolymphatic hydrops were blindly compared with 22 randomly selected, normal temporal bones. In idiopathic hydrops, the pars rugosa of the endolymphatic sac extended out of
It has been demonstrated that endolymphatic hydrops can be produced in guinea pigs by obliteration of the endolymphatic sac and this phenomenon was reproduced in our own laboratory. Interruption of the lateral semicircular duct of animals with labyrinthine hydrops produced a diminution of the
Obliteration of the right endolymphatic sac was performed by Kimura's method in 57 guinea pigs with normal hearing and vestibular function. However, 43 animals exhibited postoperative cerebellopontile disturbance and labyrinthitis detected by gait test, ABR test and histological examination. The
Three cases with postinflammatory inner ear sequelae are presented to illustrate unusual histopathologic changes. Endolymphatic hydrops without changes in the perilymphatic system was present in one ear following "influenza" meningitis and labyrinthitis ossificans in the contralateral ear. The
Delayed endolymphatic hydrops (DEH) is a unique disorder characterized by fluctuating otologic symptoms in the setting of preexisting unilateral deafness. The symptoms include aural fullness, fluctuating hearing, and/or episodes of vertigo similar to those observed in Meniere disease and may occur
OBJECTIVE
To determine whether cochlear hydrops analysis masking procedure (CHAMP) has diagnostic value in patients with definite Ménière's disease (MD) comparing the diagnostic validity index of CHAMP with those of electrocochleography (ECoG).
METHODS
A prospective study.
METHODS
Tertiary referral
Delayed endolymphatic hydrops (DEH) differs from Ménière's disease in that it occurs in pre-existing ear pathology in patients who have a profound unilateral or total deafness that was caused by infection, trauma, or unknown causes during childhood or adulthood. We performed a retrospective review
An alarming increase in the incidence of syphilitic labyrinthitis has prompted us to review the pathology of this condition. The temporal bones of two patients with congenital syphilis of the ear were studied histopathologically. They showed diffuse osteitic changes in the otic capsule associated
To better understand the pathogenesis of cytomegalovirus labyrinthitis, a guinea pig model was created. Following inoculation at several sites (cardiac, perilymph, and endolymphatic sac) in both seronegative and seropositive animals, the immunologic, histologic, and electrophysiologic responses were
We observed that some temporal bones with endolymphatic hydrops (EH) showed varying degrees of basalward displacement (towards the scala tympani) of the basilar membrane (BM) in the apical turn of the cochlea. In some, the BM was adherent to the bony wall of the scala tympani (i.e., the interscalar
To quantitatively demonstrate and classify the histopathologic changes in the cochlea of the human temporal bones with labyrinthitis ossificans (LO).
Comparative human temporal bone study.
Tertiary academic medical center.
We compared 23 temporal bone specimens from 19 deceased donors with LO
The aim of the present study was to establish an animal model of autoimmune labyrinthitis using heterologous inner ear antigen (IEAg) and to elucidate whether the experimentally induced labyrinthitis could be passively transferred. Cochlear and vestibular membranous labyrinthine tissues from bovine
