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.

There are some studies which confirmed that dysfunction in Central Nervous System(CNS) may cause a malfunction in the Peripheral Auditory system (Cochlea_ Auditory Nerve, Auditory Neuropathy), but the question is could Brain Disorder without any lesion in the Cochlea and/or Auditory nerve cause Sensorineural Hearing Loss? It means that the Audiogram shows that the patient suffers from sensorineural hearing loss but the site of the lesion is neither Sensory nor Neural while Brain may be involved in charge of this. And if the answer is yes then could we hear with our Brain and without Cochlea and /or Auditory nerve? We deal with this subject in this paper by: Otosclerosis and Meniere’s disease and The Brain Involvement. Hearing Loss following dysfunction in the Central Auditory and/or central non auditory system. Auditory Brainstem Implant in Patients who suffer from Neurofibromatosis Type two compare to Non Tumor cases, Mondini Syndrome, Michel aplasia. Possible role of Utricle and Saccule in Auditory (Hearing) System We propose a new Hypothesis that the External Ear Canal is not the only input of Auditory Signals, Sounds could transfer by our eyes and skin to the Cerebral Cortex and approach to the Cochlea (Backward Auditory input pathway of Sounds).

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.
