“…A surprising number of patients report that the hearing loss was noticed immediately on awakening suggesting that hearing loss occurred during sleep [8]. Some patients say that they heard a pop sound in the ear following which they had become deaf.…”

The study purpose was to determine the efficacy of steroids, volume expanders and antivirals in the management of idiopathic sudden sensory neural hearing loss and to establish importance of early medical intervention. In this prospective study, thirty-four patients presenting with idiopathic sudden hearing loss of 30 db or more were enrolled in study group between 2005 and 2009. Patient variables as they related to recovery were studied and include patient age, time to onset of therapy, status of contralateral ear, presence of diabetes, severity of hearing loss, pattern of hearing loss in audiogram and presence of associated symptoms, (tinnitus, vertigo). Treatment protocol with intravenous hydrocortisone, intravenous dextran and oral anti-viral agent was followed. Pre-treatment and post-treatment pure tone average was analyzed. With combination therapy the overall improvement in pure tone threshold was seen in 27 patients (79.4%). A statistically significant association was found between the time at which medical intervention was started and hearing improvement. Early intervention in patients presenting before 3 days has given 77.8% complete type 1 recovery Idiopathic sudden sensory neural hearing loss is a medical emergency. It should not be misdiagnosed. Early detection and management with volume expanders, steroids and antivirals will improve the chances of complete recovery.

“…The specific definition of what constitutes ''improvement'' or ''recovery'' after an SSNHL is not uniform among studies and reports [8]. Since most patients did not have audiograms before the SSNHL episode, the hearing in unaffected normal ear as measured at the time of diagnosis was used as standard [9].…”

“…As discussed previously in the Materials and Methods section, the current study included patient charts based on a hearing loss of greater than or equal to 20 dB from a baseline of 0 dB averaged over 3 contiguous audiometric frequencies, within 3 or fewer days, but also on the standard definition involving a greater than or equal to 30 dB threshold for hearing loss. The threshold of hearing loss greater than or equal to 20 dB has been used previously in a number of studies (12) and has been recommended as an alternative to the NIDCD definition because it is more sensitive in identifying patients with ISSHL (3). However, the wide usage of the NIDCD definition enables reliable comparisons between studies.…”

Objective: This study was conducted to determine whether the incidence of idiopathic sudden sensorineural hearing loss (ISSHL) varies throughout the year. Study Design: This study is a retrospective case review. Setting: This study was conducted at a tertiary referral center within a teaching hospital. Patients: Inclusion criteria were a diagnosis of ISSHL confirmed by audiometric data. Exclusion criteria were intracranial neoplasms, a history of Ménière's disease, previous ear procedures, chemotherapy, or radiation therapy to the head or neck. There was no exclusion criterion based on age. Ninetyseven patients met these criteria. The median age was 52 years (range, 26Y85 yr), and there were 53 (54.6%) women and 44 (45.4%) men. Main Outcome Measures: Monthly incidence counts were compiled across a 3-year period. Counts were analyzed for uneven incidence distributions and seasonal variation via standard statistical tests. Results: Overall, no evidence was found for an uneven distribution or for a peak either by W 2 ( p 9 0.1), which assesses for any uneven distribution, or by the circular mean ( p 9 0.1), which assesses for a pattern of seasonal variation. In the subset of patients (24 of 97; 24.7%) who reported experiencing an upper respiratory infection before or concurrent with the onset of ISSHL, no evidence was found for an uneven distribution of hearing loss onset throughout the year either by W 2 ( p 9 0.1) or by the circular mean ( p 9 0.1). Conclusion:The results of this study suggest that ISSHL incidence does not display uneven distribution throughout the year.

“…Sudden hearing loss has various proposed etiologies and, in a significant percentage of cases, the cause is not definitively known [1]. Among the potential mechanisms is the phenomenon of a perilymphatic fistula (PLF).…”
