1/11. Inner ear pathologic features following mumps infection. Report of a case in an adult.temporal bone studies in an adult with a moderately severe, bilateral sensorineural hearing loss revealed bilateral cochlear changes 13 years after mumps infection. The organ of corti was completely absent in the greater part of the superior horizontal basal limbs, with occasional hair cell loss throughout the rest of the cochlea. The outer sulcus cell area was degenerated. The stria vascularis was normal, as was the tectorial membrane, except for small hyaline droplets. The number of nerve fibers was extremely decreased in the spiral bony lamina of the basal turns. Basophilic material, possibily representing degeneration of otoliths, was present in the saccule and utricle, bilaterally, with small amounts in all of the ampullae. This was considered to be either a possible result of cytotoxic cancerocidal therapy, or an incidental nonspecific change.- - - - - - - - - - ranking = 1keywords = sensorineural hearing loss, hearing loss, sensorineural hearing, sensorineural, hearing (Clic here for more details about this article) |
2/11. Preserved otoacoustic emissions in postparotitis profound unilateral hearing loss: a case report.We report a case of a profound unilateral sensorineural hearing loss following epidemic parotitis, with good response of otoacoustic emissions. The patient was a 12-year-old girl who had developed a unilateral hearing impairment 2 weeks after the onset of mumps. Pure tone audiometry confirmed a profound left sensorineural hearing loss. The affected ear showed an absence of auditory brain stem responses, whereas transient evoked otoacoustic emissions and distortion product otoacoustic emissions were preserved. Epidemic parotitis virus is likely responsible for an impairment of inner hair cells, primary afferent fibers or their synapses, or a combination of these areas, and it does not seem to have a specific tropism for cochlear outer hair cells. Further follow-up will be necessary to differentiate the present case from auditory neuropathy.- - - - - - - - - - ranking = 3.4184854707607keywords = sensorineural hearing loss, hearing loss, sensorineural hearing, sensorineural, hearing (Clic here for more details about this article) |
3/11. Bilateral sensorineural hearing loss due to mumps.Viral infections implicated in acute hearing loss include rubella, measles, mumps, herpes zoster, cytomegalovirus and influenza. mumps' deafness is the best documented disorder. We describe a case where bilateral sensorineural hearing loss, following a severe mumps infection at the age of two, remained unnoticed until the age of four when the patient presented with delayed speech and language. This report emphasises the risk of permanent hearing loss as a complication of mumps infection and discusses strategies for early diagnosis and prevention.- - - - - - - - - - ranking = 5.6704378595405keywords = sensorineural hearing loss, hearing loss, sensorineural hearing, sensorineural, hearing (Clic here for more details about this article) |
4/11. Acute bilateral total deafness complicating mumps.While it is well known that mumps is a potential cause of deafness, it is not generally appreciated that it can produce total deafness. The damage is usually unilateral but bilateral disease has been recorded. A case is presented of severe bilateral hearing loss during a mumps epidemic in which, in spite of intensive conventional as well as lesser known therapy, no improvement occurred. In the absence of a successful therapeutic regime it is clearly advisable to intensify immunization in non-developed countries.- - - - - - - - - - ranking = 0.33521892977027keywords = hearing loss, hearing (Clic here for more details about this article) |
5/11. Sudden hearing loss: a clinical survey.After a brief statistic survey of general aspects the variety of clinical findings in sudden hearing loss is demonstrated by numerous observations. These illustrate the questionable role of supposed causes, the different modes of onset and course of sudden hearing loss, the audiometric findings and concomitant symptoms. The situation of both ears prior to the acute loss seems to be of great importance and offers a frame for classification, which is of clinical relevance. These features and others are discussed with regard to common theories on the etiology of sudden hearing loss. The difficulties in assessing therapeutic effects are pointed out considering the high rate of spontaneous recovery.- - - - - - - - - - ranking = 2.3465325083919keywords = hearing loss, hearing (Clic here for more details about this article) |
6/11. Etiologic aspects and orthodontic treatment of unilateral localized arrested tooth-development combined with hearing loss.In this study a case has been presented involving localized, arrested maxillary tooth development, asymmetric maxillary development, and unilateral loss of hearing. No similar case seems to have been described before. The orthodontic treatment comprised extraction of four permanent tooth germs in the maxilla and autotransplantation of mandibular teeth, followed by the use of fixed orthodontic appliances and a one-unit bridge restoration. Etiologic aspects are discussed. It is suggested that a severe attack of mumps that involved massive swelling of the parotid glands immediately after chicken pox and measles at the age of 4 to 5 years, may have resulted in a neurologic reduction of hearing and arrested tooth development. The teeth in which root development in relation to mumps does not appear to have been reported previously, whereas hearing loss after mumps has been reported. In the search for verification of this possible connection, children with arrested tooth development should be examined for reduction of hearing, and children with hearing loss after mumps ought to have their dental development checked.- - - - - - - - - - ranking = 2.2441428336604keywords = hearing loss, hearing (Clic here for more details about this article) |
7/11. Sudden deafness accompanied by asymptomatic mumps.In this study we investigated asymptomatic mumps as a possible cause of sudden deafness. We studied 131 sudden deafness patients by measuring their serum mumps antibody values. Positive IgM antibody results, which strongly suggest recent mumps infection, were revealed in 9 of the 130 patients tested (6.9%). Asymptomatic mumps infections are apparently closely related to sudden deafness. Further studies will provide more definite diagnoses of mumps deafness and might be applicable to the treatment of such hearing loss.- - - - - - - - - - ranking = 0.33521892977027keywords = hearing loss, hearing (Clic here for more details about this article) |
8/11. Unilateral hearing loss following rubella infection in an adult.A 36-year-old man was admitted to our university hospital, complaining of acute hearing loss of the right ear, which was his only hearing ear. He had developed complete deafness due to mumps in the left ear at the age of 26. Before admission, he had been diagnosed as having rubella infection. He noticed hearing loss in the right ear two days after disappearance of macular rash. headache, nausea and vertigo were not present. Three weeks after the onset of hearing loss, he was admitted to our university hospital. Pure tone audiometry revealed sensorineural hearing loss; a mild ascending audiometric curve with a marked loss at 4,000 Hz and 8,000 Hz. SISI test was positive. Caloric stimulation (ice water 10 ml/10 s) to the right ear demonstrated a normal response. rubella hemagglutination antibody titer was 512. Specific IgG antibody was over 3,200. Specific IgM antibody was positive (7.01 Enzyme immunoassay). The data indicated recent infection with rubella. He was given betamethasone for 14 days. Pure tone audiometry showed hearing improvement.- - - - - - - - - - ranking = 3.2441428336604keywords = sensorineural hearing loss, hearing loss, sensorineural hearing, sensorineural, hearing (Clic here for more details about this article) |
9/11. Neurotological findings in patients with acute mumps deafness.We report the neurotological findings in 4 cases of acute stage hearing loss due to mumps. In 2 of the cases, the less severe hearing loss which occurred in the opposite ear was shown to have improved after therapy. If patients with mumps suffer from a mild hearing loss which recovers quickly, the temporary auditory problem might go undiagnosed; thus the incidence of mumps deafness might well be higher than that reported in the literature. Two of our patients complained of dizziness. In the caloric test, a reduced response of the ear with poorer hearing was found in 3 cases, and a normal caloric response was revealed in the fourth. In the galvanic body sway test (GBST), 3 cases showed a normal response bilaterally and one case presented a normal response bilaterally in the first test, no response in the right side in the second test, and recovery of response in the third test. These findings suggest that an inner ear disorder might occur in combination with a retrolabyrinthine disorder in mumps deafness, with the former lasting longer and the latter improving earlier.- - - - - - - - - - ranking = 1.0832665409904keywords = hearing loss, hearing (Clic here for more details about this article) |
10/11. mumps labyrinthitis, endolymphatic hydrops and sudden deafness in succession in the same ear.Acute sensorineural hearing loss, mostly unilateral and reversible, is a well-known complication to mumps. Secondary endolymphatic hydrops, Meniere's syndrome, has rarely been associated with a previous mumps infection. This paper presents the case report of a woman who experienced unilateral hearing loss, vestibular symptoms and a caloric depression on the same ear during mumps. The symptoms and findings were reversible. Twelve years later she developed Meniere's symptoms in the same ear. This continued for 2 years after which she suddenly had a sensorineural hearing loss. This was localized in the mid- and high-tone area and was almost identical with the initial hearing loss 14 years earlier. Viral damage to the resorptive structures of the inner ear seems to have caused the hydrops. It also seemed to have weakened the neuronal structures of the ear, letting the initial damage become overt after repeated attacks of pathological pressure changes.- - - - - - - - - - ranking = 2.6704378595405keywords = sensorineural hearing loss, hearing loss, sensorineural hearing, sensorineural, hearing (Clic here for more details about this article) |
