Recurrent sudden sensorineural hearing loss in a 58-year-old woman with severe dizziness: a case report

Acupuncture as an early treatment for idiopathic sudden sensorineural hearing loss (ISSNHL) patients with flat or high-frequency drop audiograms: study protocol for a randomized controlled trial

BACKGROUND

Idiopathic sudden sensorineural hearing loss (ISSNHL) is a common form of deafness. Acupuncture has been used as a salvage therapy for ISSNHL in China since 200 BCE. However, the efficacy of acupuncture has not been confirmed in strictly controlled trials. We designed a randomized controlled clinical trial to evaluate the efficacy and long-term effects of acupuncture in patients with early ISSNHL.

METHODS/DESIGN

In this randomized controlled clinical trial, we will enroll 124 participants with ISSNHL diagnosed 2 to 4 weeks prior to enrollment, who have shown little hearing improvement after routine Western medical treatment (i.e., corticosteroids). 62 of these participants will have flat audiogram and the other 62 will have a high-frequency drop audiogram; they will all take Methycobal while half of the flat type and half of the high-frequency drop type will also receive acupuncture treatments for 4 weeks in a four-group design. The primary outcome measure will be the effective rate of hearing improvement (defined as the proportion of patients with at least 15-dB improvement in the hearing loss frequency band). The secondary outcome will measure the improvements in Pure Tone Average, Word Recognition Score, and Tinnitus Handicap Inventory. The assessments of the participants will be made at baseline, after treatment (week 4), and at follow-up (week 28).

DISCUSSION

This study aims to explore the efficacy and long-term effects of acupuncture in patients with ISSNHL. This study will be a randomized controlled trial with strict methodology and few design deficits. If our study yields positive results, acupuncture could be recommended as a salvage therapy for patients with ISSNHL.

Treatment of sudden hearing loss using electro-acupuncture

OBJECTIVES

Sudden neurosensory deafness is the second debilitating disease in China. In fact, the current treatment is limited to hearing aids, assistive devices and cochlear implants. However, some patients might not be suitable for surgery or even hearing aids.

METHODS

Hereby, we report a pediatric case of sudden sensorineural hearing loss accompanied by otalgia and blocked ear sensation.

RESULTS

He firstly failed with conventional treatment but later his hearing symptoms were improved with our electro-acupuncture therapy according to pure tone audiometry findings and clinical responses.

CONCLUSIONS

It may be worth trying in patients with sudden neurosensory deafness, who do not respond to routine medical treatment. In line with previous studies, the current report indicates that future observational studies or even clinical trials are needed to prove the efficacy of acupuncture on hearing loss and the accompanying symptoms.

Acupuncture Points Stimulation for Meniere's Disease/Syndrome: A Promising Therapeutic Approach

Objective. This study aims to explore evidence for acupuncture points stimulation (APS) in treatment of Meniere's disease (MD). Method. A literature search was conducted in seven databases including EMBASE, Medline, Cochrane Library, Web of Science, CBM, CNKI, and WangFang database and the data analysis was performed by using the RevMan version 5.3. Results. 12 RCTs with 993 participants were acquired after the search. The quality of most eligible studies was very low which limited the value of the meta-analysis. Compared with western medicine comprehensive treatment (WMCT), the APS alone or in combination with WMCT had a significant positive effect in controlling vertigo; however, the result was negative in hearing improvement and DHI. No adverse events were reported in the studies. Conclusion. The APS might be a promising therapeutic approach for MD. However, the currently available evidence is insufficient to make a definitive conclusion for the poor quality of included studies. More high-quality researches with larger sample size are urgently needed to assess the effectiveness and safety.

Recurrence of idiopathic sudden sensorineural hearing loss: a retrospective cohort study

OBJECTIVE

To explore the recurrence rate of idiopathic sudden sensorineural hearing loss (ISSNHL).

DESIGN

Using the Taiwan Longitudinal Health Insurance Database, we compared in a retrospective cohort study 45,715 patients with ISSNHL between January 2001 and December 2006 with 45,715 age-, gender-, and comorbidity-matched controls without ISSNHL. We followed each patient from 180 days after the initial diagnosis until the end of 2009 and evaluated the incidence of ISSNHL for 3 years minimum.

RESULTS

The cumulative incidence of ISSNHL recurrence was 4.99%. Cox proportional hazard regressions showed that the 50- to 64-year-old age group had a higher adjusted hazard ratio (1.59; 95% confidence interval: 1.40-1.81) than did the 0- to 34-year-old age group. Different comorbidities did not significantly affect the incidence of ISSNHL relapse.

CONCLUSIONS

The risk of an ISSNHL relapse in patients with a history of ISSNHL was higher than was the risk of a first occurrence of ISSNHL in the Controls. We suggest that physicians counsel patients with a history of ISSNHL to seek medical attention if they have hearing impairments because they may also have a high risk of an ISSNHL relapse.

Acupuncture therapy for sudden sensorineural hearing loss: a systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

Acupuncture has commonly been used in China, either alone or in combination with Western medicine, to treat sudden sensorineural hearing loss (SSHL). The purpose of this systematic review is to assess the efficacy and safety of acupuncture therapy for patients with SSHL.

METHODS

We searched PubMed, the Cochrane Library, Embase, China National Knowledge Internet (CNKI), Database for Chinese Technical Periodicals (VIP), and Chinese Biomedical literature service system (SinoMed) to collect randomized controlled trials of acupuncture for SSHL published before July 2014. A meta-analysis was conducted according to the Cochrane systematic review method using RevMan 5.2 software. The evidence level for each outcome was assessed using the GRADE methodology.

RESULTS

Twelve trials involving 863 patients were included. A meta-analysis showed that the effect of manual acupuncture combined with Western medicine comprehensive treatment (WMCT) was better than WMCT alone (RR 1.33, 95%CI 1.19-1.49) and the same as the effect of electroacupuncture combined with WMCT (RR 1.33, 95%CI 1.19-1.50). One study showed a better effect of electroacupuncture than of WMCT (RR 1.34, 95%CI 1.24-1.45). For mean changes in hearing over all frequencies, the meta-analysis showed a better effect with the combination of acupuncture and WMCT than with WMCT alone (MD 10.85, 95%CI 6.84-14.86). However, the evidence levels for these interventions were low or very low due to a high risk of bias and small sample sizes in the included studies.

CONCLUSION

There was not sufficient evidence showing that acupuncture therapy alone was beneficial for treating SSHL. However, interventions combining acupuncture with WMCT had more efficacious results in the treatment of SSHL than WMCT alone. Electroacupuncture alone might be a viable alternative treatment besides WMCT for SSHL. However, given that there were fewer eligible RCTs and limitations in the included trials, such as methodological drawbacks and small sample sizes, large-scale RCTs are required to confirm the current findings regarding acupuncture therapy for SSHL.

Acupuncture in treating sudden sensorineural hearing loss: a report of 2 cases

BACKGROUND

Two cases of sudden sensorineural hearing loss (SSHL) in left ear diagnosed by an ear, nose, and throat specialist are presented.

CASE REPORT

The first patient was a 22-year-old male college student with moderately severe hearing loss, tinnitus, and a feeling of fullness in the ear for 5 days. The other patient was a 48-year-old male pilot with severe hearing loss, tinnitus, and fullness in the ear for 7 days. Both patients did not respond to medical treatment, and the hearing loss became even worse. The patients were then treated with acupuncture 5 and 7 days, respectively, after hearing loss had developed. Electroacupuncture was applied to ear and neck once per day for both patients.

RESULTS

Fullness in ear disappeared during the first treatment in both cases, and the first patient also felt great improvement in hearing during the first treatment. After 10 treatments, the first patient had recovered. In the other patient, hearing had greatly improved after 19 treatments.

CONCLUSION

Acupuncture may be worth trying in patients with SSHL who do not respond to routine medical treatment.
