Poorly Differentiated

In an attempt to improve the differentiating ability of monosyllabic speech discrimination tests, two equivalent, 25-word test recordings with rectilinear distributions of item difficulty were constructed from W-22 Hirsh recordings. These lists and selected half lists of the standard W-22 recordings were then presented to 40 ears of listeners with losses ranging in severity from -10 dB to 60 dB (SRT) at sensation levels of 20, 30, 40, and 50 dB. Scores obtained with the new lists describe a less skewed frequency distribution than those obtained with the W-22 half lists. The new recordings were also more successful in differentiating between subjects with varying levels of sensorineural hearing losses, particularly between normal-hearing listeners and listeners with mild loss, who are usually poorly differentiated by W-22 tests. This was accomplished without resorting to deliberate distortion of stimulus words. These new recordings appear to have clinical usefulness in their ability to more accurately reflect differences in discrimination ability among listeners and particularly in their ability to reveal reduced discrimination in mild sensorineural hearing loss.

Abstract Till about 15 years ago, the only choice of hearing improvement for moderate sensorineural hearing loss with severe speech discrimination defect was a hearing aid. It was only after Mr. Geoff Ball, an electronic engineer who was suffering from a similar defect, started thinking of an alternative to the conventional hearing aid that the Vibrant Soundbridge came into existence, and with the passage of time the indications for the use of the same have increased.

Objective. To review our experience with intratympanic steroids (ITSs) for the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL), emphasizing the ideal time to perform follow-up audiograms.Methods. Retrospective case review of patients diagnosed with ISSNHL treated with intratympanic methylprednisolone. Injections were repeated weekly with a total of 3 injections. Improvement was defined as an improved pure-tone average ≥20 dB or speech-discrimination score ≥20%.Results. Forty patients met the inclusion criteria with a recovery rate of 45% (18/40). A significantly increased response rate was found in patients having an audiogram >5 weeks after the first dose of ITS (9/13) over those tested ≤5 weeks after the first dose of ITS (9/27) ().Conclusions. Recovery from ISSNHL after ITS injections occurs more frequently >5 weeks after initiating ITS. This may be due to the natural history of sudden hearing loss or the prolonged effect of steroid in the inner ear.

Cochlear Damage

The author's series of 3000 consecutive operations of tympanoplasty from 1960 to 1975 were reviewed in regard to the occurrence of sensorineural hearing loss as a consequence of the surgical procedure. Worsening of bone conduction thresholds by 10 dB through the frequencies 500 to 4000 cps, or a 10% reduction in speech discrimination scores were considered significant. Whereas in transcanal tympanoplasty the incidence of cochlear damage was greater in ears when initially the ossicular chain was incomplete, by contrast in combined approach tympanoplasty the risk was greater when the chain was intact initially. It was concluded that cochlear trauma was usually due to 1) the hydraulic effect of excessive stapes manipulation during the removal of disease, and 2) the development of a perilymph fistula. The unpredictable predisposing threat of cochlear fragility due to genetic and inflammatory factors was emphasized and the poor results of tympanoplasty in tympanosclerosis were underlined. The current methods of treating sensorineural hearing loss after tympanoplasty were enumerated and discussed. It was concluded that although those aimed at improving labyrinthine circulation had theoretical backing, there is as yet little experimental or clinical evidence to support the claims of their protagonists.

History Of

This is a prospective in-depth study of patients with sudden idiopathic sensorineural hearing loss. We found that 65% recover completely to functional hearing levels spontaneously and independent of any type of medical treatment. The majority do so within 14 days and many within the first few days. Prognosis can be predicted according to the slope of the initial audiogram (low-frequency losses do better than high-frequency losses), hearing at 8 kHz, erythrocyte sedimentation rates, in some select instances spatial disorientation symptoms, and speech discrimination scores. There was a very poor correlation between hearing and vestibular test abnormalities, except hypoactive calorics. There were no correlations with age (excepting the very elderly), with antecedent respiratory infections. hypertension, diabetes, or other chronic diseases. We conclude that there is a fundamental difference in the behavior of apical and basal cochlea losses, that hearing recovery is always better at low than at high frequencies, that because of the high spontaneous recovery rates, tympanotomies seeking perilymph fistulas should be delayed ten days unless there is a progressive hearing loss, and that none of the current recommended treatments, especially histamine, have any effect on the outcome.
