A comparison of endolymphatic shunt surgery and intratympanic gentamicin for meniere's disease

Popularizing Surgical Cures: Walter Dandy and the Vestibular Neurectomy for Menière's Disease at the Johns Hopkins Hospital

OBJECTIVES

To uncover the context that allowed for the vestibular neurectomy to grow in favor and practice at the Johns Hopkins Hospital in the early 20th century, and the reasons for its broad abandonment since.

METHODS

The Walter E. Dandy (1905-1946) and Samuel J. Crowe collections (1905-1920) at the Alan Mason Chesney Medical Archives were reviewed, as well as the Samuel J. Crowe and Stacy Guild Temporal Bone Collection.

RESULTS

Speculation on the etiology of Menière's disease (MD) has been countless, as have the medical and surgical interventions aimed at treating it. At the Johns Hopkins Hospital, Walter Dandy popularized the neurectomy for MD and performed 692 procedures from 1924 to 1946, believing it to be a curative therapy for vertigo. When he later modified the procedure from a total cranial nerve section to a partial vestibular neurectomy preserving auditory function, surgical candidacy expanded to include nearly any patient with vestibular symptoms. After his passing, trainees' attention shifted to traumatic injuries, likely influenced by WWII. This left the procedure scarcely used until third parties rekindled interest decades later.

CONCLUSIONS

Neurectomy as the preferential treatment for MD at the Johns Hopkins Hospital was not driven by pure scientific reasoning but was rather contingent on historical context and sponsorship by a prominent figure like Walter Dandy. Appreciation of MD's natural history has since curtailed the favorability of destructive procedures in preference for conservative management.

Triple semicircular canal occlusion with endolymphatic sac decompression for intractable Meniere's disease

Background

Meniere's disease (MD) is characterized by idiopathic endolymphatic hydrops (ELH). Frequent vertigo attacks is the most disabling symptom of MD.

Objective

This study evaluated the efficacy of triple semicircular canal occlusion combined with endolymphatic sac decompression in the treatment of frequent vertigo in patients with MD.

Methods

Eleven patients with complete medical records were included in this study conducted from May 2021 to April 2022. All patients were enrolled to undergo triple semicircular canal occlusion (TSCO) with endolymphatic sac decompression (ESD). Various tests including pure tone audiometry (PTA), vestibular evoked myogenic potentials (VEMPs), the video head impulse test (v-HIT), caloric test data, the Dizziness Handicap Inventory (DHI), the Berg Balance Scale (BBS), and the Tinnitus Handicap Inventory (THI) were performed both before and after the surgery.

Results

The successful control rate of vertigo was 100% (9/9) in the average 23-month postoperative follow-up period, with complete control rate of 88.89% (8/9) and substantial control rate of 11.11% (1/9).

Conclusion

Triple semicircular canal occlusion combined with ESD may be an effective treatment option for managing frequent vertigo attacks in patients with MD. This combination therapy has the potential to become a significant addition to the treatment framework for MD.

Triple Semicircular Canal Plugging versus Labyrinthectomy for Meniere Disease: A Retrospective Study

OBJECTIVES

The study goals were to compare the long-term efficacy of semicircular canal plugging (SCP) with labyrinthectomy in the treatment of advanced Meniere's disease (MD).

STUDY DESIGN

A retrospective study.

SETTING

Single tertiary medical center.

METHODS

A total of 116 MD patients (TSCP group of 90; labyrinthectomy group of 26) with complete medical documents in Shandong Provincial ENT Hospital, from March 2017 to March 2019 were retrospectively analyzed, including a battery of auditory and vestibular function tests, recovery time from imbalance and function level scores (FLS).

RESULTS

The total control rate of vertigo in the TSCP group was 96.7% (87/90). The rate of hearing loss was 23.3% (21/90). The control rate of vertigo in the labyrinthectomy group was 100% (26/26). All patients lost their auditory function after labyrinthectomy with a 100% hearing loss rate. There was no significant difference in the vertigo control rate between the two groups (P > 0.05). The hearing loss rate in the TSCP group was significantly lower than that in the labyrinthectomy group (P < 0.00). The median time recovered from imbalance was 15 days in TSCP group and 21 days in labyrinthectomy group, which is significantly different (P < 0.05). There was no significant difference in the FLS between the two groups (P > 0.05).

CONCLUSIONS

Compared to labyrinthectomy, TSCP can preserve hearing at a high probability; meanwhile, otolith organ function preservation benefits patients from faster vestibular compensation.

Consensus on intratympanic drug delivery for Menière's disease

Purpose

Intratympanic (IT) drug delivery receives attention due to its effectivity in treatment for Menière’s disease (MD). Due to the release of the consensuses and new evidence on IT drug delivery for MD have been published, the review with a view to supplementing the details of IT treatment of MD is indispensable.

Methods

The literatures on IT injection for MD treatment over the last two decades are retrieved, International consensus (ICON) on treatment of Menière’s disease (2018), Clinical Practice Guideline (2020) and European Position statement on Diagnosis and Treatment of Meniere’s Disease (2018) are taken into account for reference, and follow advice from experts from Europe, USA and China.

Results

Experts agree on the following: (1) The effectiveness of IT methylprednisolone (ITM) on vertigo control seems to be somewhat better than that of IT dexamethasone (ITD), and ITM can restore hearing in some cases. (2) Due to the ototoxicity of aminoglycosides, the application of intratympanic gentamicin (ITG) in MD patients with good hearing is conservative. However, some studies suggest that ITG with low doses has no significant effect on hearing, which needs to be further proved by clinical studies with high levels of evidence. (3) Currently, generally accepted treatment endpoint of ITG is no vertigo attack in a 12-month period or a vestibular loss in objective tests in the affected ear.

Conclusion

More studies with high level of evidence are needed to evaluate the drug type, efficacy, and therapeutic endpoint of IT therapy for MD.

Outcomes of Endolymphatic Sac Surgery for Meniere's Disease with and without Comorbid Migraine

Purpose

To explore outcomes of endolymphatic sac surgery for patients with Meniere's disease with and without the comorbid condition of migraine.

Materials and Methods

A retrospective chart review of adult patients undergoing endolymphatic sac surgery at a single tertiary care center from 1987 to 2019 was performed. All adult patients who failed medical therapy and underwent primary endolymphatic sac surgery were included. The main outcome measures were vertigo control and functional level scale (FLS) score. Patient characteristics, comorbidities, and audiometric outcomes were tracked as well.

Results

Patients with Meniere's disease and migraine had a stronger association with psychiatric comorbidities (64.29% vs. 25.80%, p=0.01), shorter duration of vertigo episodes (143 vs. 393 min, p=0.02), and younger age (36.6 vs. 50.8 yr, p=0.005) at the time of endolymphatic sac surgery. Postoperative pure tone averages and word recognition scores were nearly identical to preoperative baselines. Class A vertigo control (47.92%) was most common, followed by class B vertigo control (31.25%). The FLS score improved from 4.2 to 2.8 (p < 0.001). Both patients with and without migraine had classes A-B vertigo control (66.67% vs. 80.95%) without any statistically significant difference (p=0.59). Of the patients who required secondary treatment (10.42%), none had migraine.

Conclusions

Endolymphatic sac surgery is an effective surgical intervention for Meniere's disease with and without migraine. Patients with comorbid migraine tend to be younger and present with psychiatric comorbidities.

Pharmacological, surgical and diagnostic innovations in Meniere's disease: a review

Meniere's disease is an inner ear disorder characterized by the presence of endolymphatic hydrops in the inner ear and symptomatology of recurrent and debilitating vertigo attacks, tinnitus, aural fullness, and fluctuating sensorineural hearing loss. Although many therapeutic options for MD have been proposed during years, no consensus has been reached by the scientific community. In the last decade, many therapeutic options have been proposed, as intratympanic steroid, intratympanic gentamicin, and intravenous glycerol. Recently, the role of the antisecretory factor in the diet of MD patients have been investigated. Surgery is recommended for intractable MD; some authors proposed new approaches including transcanal endoscopic infracochlear vestibular neurectomy, new marsupiliazation technique in sac surgery, and tenotomy of the stapedius and tensor tympani muscles.
