ZusammenfassungAs a whole the effect of an explorative tympanoscopy with sealing the round/oval window(s) in cases of a profound idiopathic unilateral sudden hearing loss (ISSNHL) has been analyzed (data: own study cases and review of literature) and the results have been compared to that of intratympanal steroid injections published elsewhere. In detail the topics of the chapters focused on: Comparison of epidemiologic data, anamnestic and clinical findings including hearing results of our study group with those published Time course of hearing improvement after explorative tympanoscopyand sealing of the round/oval window Compilation of parameters influencing the extent of the initial hearing loss and the hearing gain after surgical therapy Perilymphatic fistulas as an etilogical factor causing a sudden profound hearing loss Comparison of those cases which have been treated by obliteration of the round/oval window with and without corticoid-soaked connective tissue Comparison of patients (data sampled by literature and own cases) treated with intratympanal corticoid injections on the one side or explorative tympanscopy with sealing of the round/oval window on the other side.

The speech of a five-year-old boy who suffered a profound hearing loss following meningitis was sampled at two-week intervals for nine months. Speech samples were subjected to phonetic transcription, spectrographic analysis, and intelligibility testing. Immediately post-trauma, the child displayed slightly slower, F o elevated, acoustically intense speech in which phonemic distortion and syllabification of consonants occurred occasionally; single word intelligibility was depressed below normal between 20–30%. By the 18th week, a sudden decline in intelligibility, increasing monotony of pitch, and a pattern of strongly emphatic, prolonged, aspirated, syllabified, and increasingly distorted consonants were manifest. At year's end, the child's speech bore some resemblance to the speech of the deaf in terms of suprasegmentals, intonation, and intelligibility, but differed because the child rarely, if ever deleted speech sounds or diphthongized vowels strongly. It is speculated that phonetic processes such as diphthongization, syllabification, and prolonged duration may be strategies for enhancing feedback during speech.

In 1971, one of the authors reported sudden deafness associated with labyrinthine window membrane ruptures. Eighteen additional cases have been explored surgically since then. Data on 21 cases are presented. Sudden profound cochlear deafness has now been encountered in 21 cases which were surgically explored. In 15 instances, fistulae of round, oval, or both windows were encountered and repaired. In 10 of the 15, there was a definite history of sudden exertion or trauma prior to onset. The oval window alone was ruptured in nine patients, the round window alone in one, and both windows were ruptured in five patients. The oldest patient was 62 years and the youngest 11 years of age. Differential audiological studies showed profound losses in all cases. Almost every case was studied by pure tone AC-BC and speech audiometry, Békésy, and impedance tests. Whenever possible other audiologic tests, such as recruitment, tone decay, and SISI were performed. These findings are presented in detail. Vestibular function was studied by electronystagmography (ENG) in 15 of the 21 cases surgically explored. There was evidence of vestibular dysfunction in almost every case with sudden hearing loss. Significant ENG details are presented. Surgical repairs of ruptured window membranes were followed by improvements in some of the patients. Postoperative audiologic data are presented. The theoretical aspects include discussion of possible cerebrospinal fluid (CSF) perilymph pathways between cochlear aqueduct and scala tympani and between internal auditory meatus and scala vestibuli. It is concluded that spontaneous labyrinthine window ruptures must now be added to the etiologic factors in “sudden hearing loss.” It is premature to set down criteria for surgical intervention in such cases. Further careful studies are necessary.

The present study examined the phenomenon of acclimatization in persons with a severe-to-profound hearing loss. A secondary purpose was to examine the efficacy of a digital nonlinear power hearing aid that has a low compression threshold with expansion for this population. Twenty experienced hearing aid users wore the study hearing aids for three months and their performance with the study hearing aids was evaluated at the initial fitting, one month, and three months after the initial fitting. Performance of their current hearing aids was also evaluated at the initial fitting. Speech recognition testing was conducted at input levels of 50 dB SPL and 65 dB SPL in quiet, and 75 dB SPL in noise at a +10 SNR. Questionnaires were used to measure subjective performance at each evaluation interval. The results showed improvement in speech recognition score at the one-month evaluation over the initial evaluation. No significant improvement was seen at the three-month evaluation from the one-month visit. In addition, subjective and objective performance of the study hearing aids was significantly better than the participants' own hearing aids at all evaluation intervals. These results provided evidence of acclimatization in persons with a severe-to-profound hearing loss and reinforced the precaution that any trial of amplification, especially from linear to nonlinear mode, should consider this phenomenon.

AbstractObjective:To evaluate the correlation between caloric and vestibular evoked myogenic potential test results, initial audiogram data, and early hearing recovery, in patients with idiopathic sudden hearing loss.Materials and methods:One hundred and four patients with unilateral idiopathic sudden hearing loss underwent complete neurotological evaluation. Results for vestibular evoked myogenic potential and caloric testing were compared with patients' initial and final audiograms.Results:Overall, abnormal vestibular evoked myogenic potential responses occurred in 28.8 per cent of patients, whereas abnormal caloric test results occurred in 50 per cent. A statistically significant relationship was found between the type of inner ear lesion and the incidence of profound hearing loss. Moreover, a negative correlation was found between the extent of the inner ear lesion and the likelihood of early recovery.Conclusion:In patients with idiopathic sudden hearing loss, the extent of the inner ear lesion tends to correlate with the severity of cochlear damage. Vestibular assessment may be valuable in predicting the final outcome.

AbstractFactors affecting auditory improvement after stapes surgery were investigated retrospectively on a study group of 106 otosclerotic ears (86 subjects). While the closure of the air-bone (A-B) gap after surgery was good at 2 kHz and 4 kHz, it was poor at 8 kHz and at frequencies lower than 1 kHz. Under 1 kHz, the lower the frequency, the worse the A-B gap after surgery. Stapedotomy and partial stapedectomy showed better post-operative hearing gain at 4 kHz than total stapedectomy. Total stapedectomy scored significantly better at 250 Hz and 500 Hz than stapedotomy. There was a close relationship between the pre-operative and post-operative A-B gap at frequencies under 1 kHz. The smaller the pre-operative A-B gap, the better the closure of the post-operative A-B gap at frequencies under 1 kHz. The smaller the pre-operative A-B gap, the better the closure of the post-operative A-B gap at these frequencies. It was speculated that otosclerotic ears with a larger pre-operative airbone gap might have another lesion in the middle ear other than the oval window.

The incidence of perilymphatic fistula as cause of sudden hearing loss is not known. We present a case with sudden unilateral hearing loss associated with a positive β-trace protein test of an epipharyngeal fluid sample. The patient presented with sudden sensorineural hearing loss on the right side. A stapedotomy had been performed nine months previously due to otosclerosis. Intravenous therapy for the treatment of sudden hearing loss was unsuccessful. At the time of sudden hearing loss, epipharyngeal fluid was collected using a Raucocel sinus pack. Investigation using rocket immunoelectrophoresis showed the presence of β-trace protein. Upon repeating tympanoscopy there was no obvious labyrinthine fluid egress, but the oval window was sealed with fibrin sponge and fibrin glue. The patient’s hearing improved over a period of five months.

<p>Sudden Hearing loss has been rarely reported as a presenting symptom of malaria fever. It’s even more rare to have a bilateral profound sudden sensorineural hearing loss. A 19 years old female student presented with fever, body weakness, hearing loss with tinnitus. Laboratory investigations done were essentially normal except blood film for malaria parasite which showed a high concentration of the parasite in blood on both occasions. Otoacoustics emission test was passed bilaterally while auditory steady state response showed profound hearing loss bilaterally. Normal hearing was restored within 48 hrs of commencement of anti-malaria drugs and low dose steroids. </p>

Purposes: To compare the speechreading between individuals with hearing impairment and with normal hearing levels to verify the factors that influence the speechreading among hearing impaired patients. Methods: Forty individuals with severe-to-profound hearing loss aged between 13 and 70 years old (study group) and 21 hearing individuals aged between 17 and 63 years old (control group) were evaluated. As a research instrument, anamnesis was used to characterize the groups; three speechreading instruments, presenting stimuli via a mute video, with a female speaker; and a vocabulary test, to verify their influence on speechreading. A descriptive and analytical statistics (ANOVA test and Pearson's correlation), adopting a significance level of 0.05 (5%). Results: A better performance was observed in the group with hearing impairment in speechreading tests than in the group with hearing individuals. By analyzing the group with hearing loss, there was a mean difference between tests (p<0.001), which also showed correlation between them. Individuals with pre-lingual hearing loss and those who underwent therapy for speechreading had a better performance for most speechreading instruments. The variables gender and schooling showed no influence on speechreading. Conclusion: Individuals with hearing impairment had better performance on speechreading tasks in comparison to people with normal hearing. Furthermore, it was found that the ability to perform speechread might be influenced by the vocabulary, period of installation of the hearing loss, and speechreading therapy.

Sudden hearing loss from simultaneous rupture of both oval and round windows, occurring in the only hearing ear of a child, is described. The condition was surgically managed with recovery of hearing. Of particular note was the presence of air aspirated into the labyrinth at the time of membrane rupture, which has not previously been described. The possible mechanisms and some clinical correlates associated with anatomic predisposition to such rupture are discussed.
