Steroids, carbogen or placebo for sudden hearing loss: a prospective double-blind study

There is no consensus regarding treatment modalities for idiopathic sudden sensorineural hearing loss (SNHL). In order to evaluate the effectiveness of steroid or carbogen inhalation therapies, a prospective double-blind placebo controlled study was designed. All 41 patients enrolled in the study had unilateral SNHL with no prior history of SNHL, otological pathological history or otoscopic findings. Patients were assigned to four treatment groups: prednisone tablets, placebo tablets, carbogen inhalation or room air inhalation. All were treated for 5 days. The audiometric data at admission was compared to that at day 6 and to data collected at follow-up (average 33 days). Results revealed no significant difference between the groups for early or late audiometric outcome. Age, time from onset of symptoms to initiation of treatment, tinnitus, audiogram configuration, and the presence of vertigo at onset did not significantly affect the outcome. The discrimination scores that were poor in all patient groups on admission improved within days in all groups. These findings suggest that steroids or carbogen inhalation have no therapeutic advantage over placebo. Also, regardless of treatment modality, hearing continued to improve for at least a month after treatment was stopped. Received: 6 April 2001 / Accepted: 9 May 2001     

Idiopathic sudden sensorineural hearing loss: Effectiveness of salvage treatment with low-dose intratympanic dexamethasone

Objectives:To evaluate hearing outcome of salvage treatment with intratympanic steroids(ITS)in idiopathic sudden sensorineural hearing loss(ISSNHL)refractory to initial systemic steroid(SS)therapy.Material and methods:A retrospective medical chart review was conducted on 54 consecutive patients with ISSNHL refractory to SS.Salvage treatment with a low dose intratympanic dexamethasone(4 mg/ml)was offered after one week of primary treatment.Patients were divided into two groups:25 patients accepted ITS(treatment group)and 29 patients did not undergo additional treatment(control group).A pure tone average(PTA)gain of at least 10 dB was considered hearing improvement.Results:Hearing improvement rate was higher in ITS group compared to control group(40%vs.13.8%,p=0.035).A mean PTA improvement of 8.6±9.8 dB was observed in the ITS group and,whereas the control group had an average hearing gain of 0.7±2 dB(p<0.001).Audiometric analysis revealed a significant hearing gain in ITS group at all tested frequencies compared to control group(p<0.05).Analysis of the selected variables,identified intratympanic steroid treatment as the only independent prognostic factor for hearing improvement(OR=4.2,95%CI:1.1e15.7;p=0.04).Conclusion:Intratympanic low dose dexamethasone is effective in patients with incomplete hearing recovery after primary systemic steroid treatment.

Chikungunya virus induced sudden sensorineural hearing loss

The aim of this study is to demonstrate the association of Chikungunya virus and sudden sensorineural hearing loss. In the case report described we had a case which developed sudden unilateral sensorineural hearing loss following chikungunya fever. A 15-year-old female presented to us with the complains of unilateral sudden onset of hearing loss following an episode of fever, arthralgia and rashes 1 month ago. At the time of these symptoms there were many cases of chikungunya fever in the city, three being in her locality. Clinically Chikungunya fever was suspected and a positive serological test further confirmed our diagnosis. The hearing loss could thus be attributed to Chikungunya virus. Viruses have always been implicated in causing sudden sensorineural hearing loss but Chikungunya virus as a cause has not been documented earlier making this case report a unique one.     

Intratympanic steroids in severe to profound sudden sensorineural hearing loss as salvage treatment

Objectives

Intratympanic steroids are being increasingly used in the treatment of sudden sensorineural hearing loss (SSNHL) after the failure of systemic therapy. This study evaluated the efficacy of administering intratympanic dexamethasone (ITD) as a salvage treatment for severe to profound SSNHL.

Methods

We reviewed the medical records of patients who presented with severe to profound SSNHL between January 2007 and December 2009. ITD was given about 14 days after the initial systemic treatment. Successful recovery was defined as complete or partial recovery using Sigel''s criteria. We compared the results of treatment between the severe SSNHL (S-SSNHL) and profound SSNHL (P-SSNHL) groups.

Results

All the patients in the S-SSNHL group showed significant improvement, as compared to the P-SSNHL group (P=0.017). The recovery rate after the initial systemic treatment was 36% (9/25) in the S-SSNHL group and 18.1% (4/22) in the P-SSNHL group (P=0.207). In comparison, the recovery rate of ITD as a salvage treatment was 37.5% (6/16) in the S-SSNHL group and 5.5% (1/18) in the P-SSNHL group (P=0.03).

Conclusion

Our comparative study dose not support the efficacy of ITD as salvage treatment for patients with P-SSNHL as compared with that for S-SSNHL. We recommend that patients with P-SSNHL be informed about the low efficacy of ITD as a salvage treatment.

Analysis of thyroid dysfunction in patients with sudden sensorineural hearing loss

BackgroundSudden sensorineural hearing loss (SSHL) refers to the sudden occurrence of unexplained sensorineural hearing loss. The present study showed that different systemic diseases had different influence on the occurrence and hearing outcome of SSHL. Thyroid hormone is one of the important factors for the development of fetal ear and auditory function. However, the distribution of thyroid dysfunction in SSHL patients and the effect of thyroid dysfunction on the occurrence and hearing outcome of SSHL has not been studied.MethodsIn this study, a retrospective analysis had been done in 676 patients with SSHL. We had described the distribution of thyroid function in patients with SSHL in detail, and by the statistical method, analyzed the relationship between the hearing outcome and thyroid dysfunction, respectively.ResultsIn all patients, 24.41% (165/676) had abnormal thyroid function testing results. The onset age of SSHL in FT3 abnormal group (including low and high group) was younger than that in normal FT3 group. Recovery group had more patients with lower-than-normal T3 level as compared to non-recovery patients. Significant associations between T3 levels and hearing outcome were observed in the subgroup with longer time elapse between symptom onset and treatment (≥14 d).ConclusionThe incidence of thyroid dysfunction in SSHL is significantly higher than in the general population. There was obvious relationship between T3 and FT3 item of thyroid dysfunction and the onset time and hearing outcome of SSHL, which indicated that T3 or FT3 indicator may be one of the affecting factors for the SSHL. Early screening and diagnosis of thyroid dysfunction, especial T3 level, may help to evaluate the prognosis in SSHL patients.
