Abstract PDF: Objectives
This study aimed to compare the efficacy of a combined steroid and diuretic (isosorbide) treatment with that of steroid-only treatment in patients with acute low-tone sensorineural hearing loss (ALHL).
Methods
A total of 34 patients with ALHL were recruited between January 2018 and December 2019 and randomized into two groups: a steroid-with-diuretic (isosorbide) group and a steroid-only group. The steroid-with-diuretic group received oral methylprednisolone for 10 days and isosorbide for 14 days, while the steroid-only group received methylprednisolone for 10 days. Hearing outcomes were measured using pure-tone audiometry at 8 weeks posttreatment. The outcomes were the absolute hearing gain at low frequencies (125, 250, and 500 Hz) and the recovery rate, which was classified into complete, partial, unchanged, progressive, and fluctuating.
Results
Of 34 patients, 30 (15 in each group) were analyzed. No significant differences were observed in baseline characteristics between the groups. The steroid-with-diuretic group showed higher absolute hearing gains at all three low frequencies than the steroid-only group, but the differences were not statistically significant complete recovery was observed in 13 patients in each group, with partial recovery in two patients in the steroid-with-diuretic group and unchanged outcomes in two patients in the steroid-only group. No patient exhibited disease progression.
Conclusions
Although combined steroid and diuretic therapy yielded better hearing outcomes than steroid-only therapy, the differences were not statistically significant. Further studies with larger sample sizes and extended follow-up periods are necessary to confirm these findings.

Abstract PDF: Objectives
Sudden sensorineural hearing loss and Meniere disease can be managed with intratympanic steroid injection (ITSI) as a primary treatment. The aim of this study was to compare the effectiveness of ITSI versus oral diuretics for acute low frequency sensorineural hearing loss (LFHL) with vertigo.
Methods
A total 76 patients with LFHL that had developed within previous 2 weeks were enrolled and categorized into 2 groups: treated with ITSI four times on 4 consecutive days (ITSI group; 42 patients) and treated with diuretics orally for 2 weeks (diuretics group; 34 patients). After 6 months, we analyzed treatment outcomes using subjective improvement and audiometric change.
Results
Hearing thresholds at low frequencies ≤500 Hz were significantly improved in both ITSI and diuretics group (p＜0.05). The cure rate of ITSI group was not significantly higher than that of diuretics group (54.8% vs. 52.9%, p＞0.05). For subjective symptoms, there were no significant differences of improvement rate in both groups (ITSI 64.3% vs. diuretics 61.8%, p＞0.05). In pure tone audiometry, the improvement rate of ITSI group was not significantly different from that of diuretics group (78.6% vs. 70.6%, p＞0.05). There was a significant correlation between the cure rate and duration of symptoms.
Conclusions
Both ITSI and diuretics are effective treatment modalities for acute LFHL with vertigo within 2 weeks of development. There is no difference of treatment outcomes between ITSI and diuretics in patients with acute LFHL and vertigo.

Abstract PDF: Objectives
Intratympanic dexamethasone (ITD) is a standard treatment for patients with sudden sensorineural hearing loss. The aim of this study was to evaluate the effectiveness of ITD vs. combination of ITD and diuretics for acute low frequency sensorineural hearing loss (LFHL) with vertigo. Methods: A total 31 patients with LFHL that had developed within previous 2 weeks were enrolled and categorized into two groups: treated with ITD four times on 4 consecutive days (ITD group; 17 patients) and treated with ITD in the same way and diuretics orally for 2 weeks (combination group; 14 patients). After 6 months, we analyzed treatment outcomes using subjective improvement and audiometric change. Results: Hearing thresholds at low frequencies ≤500 Hz were significantly improved in both ITD only and combination group (p＜0.05). The cure rate of combination group was not significantly higher than that of ITD only group (57.1% vs. 52.9%, p＞0.05). For subjective symptoms, there were no significant differences of improvement rate in both groups (combination 64.3% vs. ITD only 64.7%, p＞0.05). In pure tone audiometry, the improvement rate of combination group was not significantly different from that of ITD only group (71.4% vs. 76.5%, p＞0.05). There was a significant correlation between the complete recovery rate and duration of symptoms. Conclusion: ITD alone is an effective treatment modality for acute LFHL with vertigo within 2 weeks of development. Combined ITD and diuretics have no additive effect for the recovery of hearing in patients with LFHL.

Abstract PDF: et, and the characteristics of vertigo. Results: Median follow-up was 29 months (range, 27−37 months). Patients had a mean age at onset of 48.2 years and a mean duration of 2.75 years. An obvious female predilection was found, and unilateral caloric paresis (≥25%) was seen in 23.3%. Of the 30 patients, symptoms resolved in 80% but were unchanged in 20%. No patient with RV developed a central nervous system disease or benign paroxysmal positional vertigo during follow-up. Conclusion: The present study shows that in the majority of cases, vertigo resolved following diuretics medication. In cases of the patients with severe or disabling recurrent vestibulopathy, the diuretics medication may be effective in reducing the frequency of vertigo attacks.

Abstract PDF: Objectives
In Meniere's disease, medical treatment using diuretics has been the mainstream of management. But the effects of medical treatment are very difficult to evaluate because of many variables. Authors tried to investigate the effects of diuretics on Meniere's disease through the change of symptoms. Materials and Method: From January, 1995 to December, 2000, the twenty patients with definite Meniere's disease who has been followed up over 24 months were retrospectively reviewed. They had no history of previous medication, and were managed with diuretics for the first time. The change of frequency of vertigo, the threshold of pure tone audiometry, type of audiogram were analyzed at each period during 6 month before treatment, during 6 month at 1, 2 and 4 years after treatment.
Results
The ratio of sex was 1:1(male 10, female 10), the average age of diagnosis was 53.9 year old, and the average follow up duration was 39.3 month. By medical treatment, vertigo symptom was significantly controlled in 56.2% at 2 year after treatment. Among 20 patients, 5 patients failed to medical treatment and underwent the sac decompression (N=1) and intratympanic gentamicin injection (N=4). The change of pure tone audiometry was from 34.5 dB before treatment to 38 dB at 24 months and 44.2 dB at 48 months after treatment. The most type of audiometry was flat type and flat type was increased with time.
Conclusion
In Meniere's disease, the medical treatment controlled significantly the vertigo frequency in 50~60%. But the hearing threshold was aggravated with time after treatment despite of medical treatment.
