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

OBJECTIVE: To evaluate caloric response changes after endolymphatic sac decompression (ESD), together with hearing outcomes and the functional benefit of the operation.
METHODS: A retrospective chart review of subjects who underwent endolymphatic sac decompression at a tertiary referral centre was performed. Data on audiological results, caloric testing, and functional level scale of the patients were analysed.
RESULTS: Twenty-eight patients who met our criteria were eligible for enrolment in the study. The average follow-up after surgery was 25 months (range, 13-41). Postoperative pure-tone threshold averages and reduced vestibular response values (RVR) were not significantly altered by ESD; whereas, functional level scores improved significantly.
CONCLUSIONS: Endolymphatic sac decompression is a surgical procedure that preserves hearing and vestibular function, and improves the daily functional level of patients with Ménière\'s disease. ESD can be preferred both in bilateral and unilateral disease because it does not alter vestibular function and preserves hearing.

OBJECTIVE: To study the efficacy predictors of endolymphatic sac decompression (ESD) in Meniere\'s disease (MD), and to establish and verify the prediction model of vertigo after ESD in patients with MD.
METHODS: The retrospective cohort data of 56 patients with unilateral MD who underwent ESD surgery were recorded. A stepwise regression method was used to select optimal modeling variables, and we established a logistic regression model with the outcome of vertigo after ESD. The bootstrap method was used for internal validation.
RESULTS: Potential predictors included sex, age, follow-up duration, disease course, attack duration, frequency of attack, pure-tone threshold average (PTA) of the patient\'s speech frequency, audiogram type, glycerin test results, MD subtype, and 10-year atherosclerotic cardiovascular disease risk classification. Using the stepwise regression method, we found that the optimal modeling variables were the audiogram type and PTA of the patient\'s speech frequency. The prediction model based on these two variables exhibited good discrimination [area under the receiver operating characteristic curve: 0.72 (95% confidence interval: 0.57-0.86)] and acceptable calibration (Brier score 0.21).
CONCLUSIONS: The present model based on the audiogram type and PTA of the patient\'s speech frequency was found to be useful in guidance of ESD efficacy prediction and surgery selection.

UNASSIGNED: This study aimed to investigate the effect of vascular risk factors on the outcomes of endolymphatic sac decompression (ESD) surgery in patients with Meniere\'s disease.
UNASSIGNED: The study included 56 patients with Meniere\'s disease, who had undergone unilateral ESD surgery. The patients\' vascular risk factors were assessed based on the preoperative 10-year atherosclerotic cardiovascular diseases risk classification. Those with no or low risk were defined as the low-risk group, while those with medium, high, or very high risk were defined as the high-risk group. The correlation between the vascular risk factors and ESD efficacy was evaluated by the comparison of vertigo control grade between the two groups. The functional disability score was also assessed to investigate whether ESD improved the quality of life in Meniere\'s disease patients with vascular risk factors.
UNASSIGNED: After ESD, 78.95 and 81.08% of patients from the low-risk and high-risk groups, respectively, demonstrated at least grade B vertigo control; no statistically significant difference was observed (p = 0.96). The postoperative functional disability scores in both groups were significantly lower compared with those before surgery (p < 0.01), with a median decrease of two (1, 2) points in both groups. No statistically significant difference between the two groups was observed (p = 0.65).
UNASSIGNED: Vascular risk factors have little effect on the efficacy of ESD in patients with Meniere\'s disease. Patients with one or more vascular risk factors can still experience a not poor vertigo control and improved quality of life after ESD.

OBJECTIVE: To evaluate if endolymphatic sac decompression (ESD) significantly improves secondary symptoms of Meniere\'s disease including tinnitus and aural fullness.
METHODS: Survey study with retrospective chart review.
METHODS: Tertiary care center.
METHODS: Survey of adult patients with Meniere\'s disease that underwent primary ESD surgery from 2015 to 2020. Subjective reporting of pre- and postoperative aural fullness and tinnitus based on postoperative survey. Survey results and audiologic data of the patients that reported were compared pre- and postoperatively.
RESULTS: Statistical analysis was performed using weighted kappa statistics to examine the level of agreement. There was a value of 0.12 for pre- and postoperative aural fullness, indicating a difference in the two groups with 77 % having improvement and only 4 % having worsening. There was a value of 0.21 for pre- and postoperative tinnitus, demonstrating a lack of agreement with 58 % having improvement and 4 % having worsening. Overall, there was significant improvement in both tinnitus and aural fullness postoperatively. There was no significant difference in word recognition score, speech reception threshold, or pure tone average between the pre- and postoperative group based on paired t-test.
CONCLUSIONS: There is a significant improvement in both aural fullness and tinnitus for patients undergoing ESD with no negative effect on audiologic status. ESD is a viable option for treatment of Meniere\'s disease with vertigo, aural fullness, and tinnitus relief. Future prospective studies are needed to further improve the evidence of ESD\'s effect on secondary symptoms of Meniere\'s disease.

OBJECTIVE: The aim of the present study was to describe and evaluate the results of a new technique in endolymphatic sac decompression surgery.
METHODS: Forty-three patients with intractable unilateral Meniere\'s disease were selected. Endolymphatic sac was identified after simple mastoidectomy, and its lateral layer was incised, using a sickle knife. Outer layer of the sac was turned around and placed under the anterior bony border.
RESULTS: Mean duration of the follow-up was 24 months. Mean tinnitus handicap index, pure tone average (PTA) on thresholds at 500, 1000, 2000, and 4000 Hz, mean speech reception threshold, mean speech discrimination score, hearing stage, and mean vertigo score before and after surgery were evaluated.
CONCLUSIONS: The new marsupialization technique with anterior bony border is a safe and effective way to improve tinnitus, vertigo, and ear fullness among these patients. According to PTA and hearing stage, this surgery can control progressive hearing loss.
METHODS: 3.

Ménière\'s disease (MD) is a clinical condition defined by spontaneous vertigo attacks (each lasting 20 minutes to 12 hours) with documented low- to midfrequency sensorineural hearing loss in the affected ear before, during, or after one of the episodes of vertigo. It also presents with fluctuating aural symptoms (hearing loss, tinnitus, or ear fullness) in the affected ear. The underlying etiology of MD is not completely clear, yet it has been associated with inner ear fluid volume increases, culminating in episodic ear symptoms (vertigo, fluctuating hearing loss, tinnitus, and aural fullness). Physical examination findings are often unremarkable, and audiometric testing may or may not show low- to midfrequency sensorineural hearing loss. Imaging, if performed, is also typically normal. The goals of MD treatment are to prevent or reduce vertigo severity and frequency; relieve or prevent hearing loss, tinnitus, and aural fullness; and improve quality of life. Treatment approaches to MD are many, and approaches typically include modifications of lifestyle factors (eg, diet) and medical, surgical, or a combination of therapies.
The primary purpose of this clinical practice guideline is to improve the quality of the diagnostic workup and treatment outcomes of MD. To achieve this purpose, the goals of this guideline are to use the best available published scientific and/or clinical evidence to enhance diagnostic accuracy and appropriate therapeutic interventions (medical and surgical) while reducing unindicated diagnostic testing and/or imaging.

Background: Endolymphatic sac decompression surgery (ESDS) is commonly used for intractable Meniere\'s disease, but its effect remains controversial because of the low rate of vertigo control.Objectives: In the present study, we examined ESDS combined with posterior tympanotomy with local steroids as a new therapeutic strategy for intractable Meniere\'s disease.Materials and methods: This retrospective study enrolled 19 patients with Meniere\'s disease using ESDS combined with posterior tympanotomy with local steroids between 2015 and 2018. Postoperatively we recorded and evaluated changes in vertigo attack frequency and hearing level.Results: Vertigo episodes decreased from 3.6 ± 3.2 times preoperatively to 0.2 ± 0.5 times postoperatively, with 89.5% complete vertigo control rate. Mean PTA decreased from 40.5 ± 21.3 dB to 39.5 ± 17.5 dB postoperatively, with 21.1% improvement rate.Conclusions and significance: The present findings suggest that ESDS combined with posterior tympanotomy with local steroids could improve clinical results of hearing as well as vertigo control for intractable Meniere\'s disease.
