Aural fullness and transtympanic ventilation tubes in Ménière's disease: a scoping review

Ear fullness characteristics and prognosis in patients with all-frequency sudden sensorineural hearing loss

OBJECTIVE

This study investigated the characteristics and prognosis of the feeling of ear fullness in patients with unilateral all-frequency sudden sensorineural hearing loss.

METHODS

Our study included 56 patients with a diagnosis of unilateral all-frequency sudden sensorineural hearing loss accompanied by a feeling of ear fullness and 48 patients without a feeling of ear fullness. The condition of these patients was prospectively observed.

RESULTS

Positive correlations were observed between grading of feeling of ear fullness and hearing loss in patients with a feeling of ear fullness (r = 0.599, p < 0.001). No significant differences were observed in the total effective rate of hearing recovery between patients with and without a feeling of ear fullness after one month of treatment (Z = -0.641, p = 0.521). Eighty-six per cent of patients (48 out of 56) showed complete recovery from the feeling of ear fullness. There was no correlation between feeling of ear fullness recovery and hearing recovery (r = 0.040, p = 0.769).

CONCLUSION

The prognosis of feeling of ear fullness is good. There was no correlation between feeling of ear fullness recovery and hearing recovery for all-frequency sudden sensorineural hearing loss patients.

Vertiginous Episodes in Menière Disease following Transmyringeal Ventilation Tube Insertion: A Systematic Review on the Current State of Evidence

Introduction  Menière disease (MD) is a disorder characterized by episodes of vertigo, sensorineural hearing loss, tinnitus and aural fullness. Objectives  To assess the effect of ventilation tube insertion (VTI) on vertiginous episodes in patients (≥ 18 years old) with MD. Data Synthesis  A systematic literature search on randomized clinical trials (RCTs), nonrandomized trials and other systematic reviews was performed. The Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) approach was used to assess the overall certainty of evidence. Two RCTs and four nonrandomized studies were identified. Data extraction was only possible for one RCT. Results showed that the number of patients with no vertigo attacks significantly increased following active treatment (relative risk 1.52; [95% confidence interval: 1.19-1.94]). The quality of evidence was rated as low. None of the nonrandomized trials included a proper control group, which hindered data extraction and quality assessment. Conclusion  There are currently no RCTs that specifically assess the efficacy of VTI in patients with MD. Current limited data suggest a considerable positive effect on the number of vertiginous episodes in patients with MD. However, due to poor evidence, a fluctuating course and a substantial placebo-effect associated with MD-treatment, no solid conclusion(s) regarding the efficacy of VTI can be made. There is a need for high-quality RCTs.

Endolymphatic hydrops mimicking obstructive Eustachian tube dysfunction: preliminary experience and literature review

PURPOSE

Aural fullness is a common symptom of middle ear diseases, most importantly Eustachian tube dysfunction (ETD). Yet, aural fullness may also be caused by inner ear disorders, such as hydropic ear diseases. Here, we report our experience with endolymphatic hydrops (EH) mimicking ETD. Furthermore, we review the literature related to (i) EH as a differential diagnosis of symptoms suggesting ETD and (ii) the pathophysiology and treatment of aural fullness due to inner ear disorders.

METHODS

We retrospectively included adult patients with aural fullness as chief complaint and radiographically diagnosed EH. Hearing and Eustachian tube function were assessed using audiometry, tympanometry, and tubomanometry. Primarily suspected ETD was treated by balloon dilatation of the Eustachian tube (BDET). The endolymphatic space of the inner ear was imaged using gadolinium-enhanced MRI (Gd-MRI) including a 3D-real inversion-recovery sequence after intravenous gadolinium administration.

RESULTS

We report three affected ears of two patients (two females, age 42 and age 51) with aural fullness as chief complaint. Audiometry of main speech frequencies was normal in all affected ears. In one ear, there was a type A tympanogram and in two ears, there was a type B tympanogram. In both patients, medical treatment for ETD and BDET were unsuccessful. Gd-MRI of the inner ears revealed cochlear EH in 3/3 ears affected by aural fullness, but not in the unaffected ear.

CONCLUSION

EH may underlay cases with aural fullness and could in these cases explain unsuccessful treatment for ETD. As ETD is often treated by invasive procedures, distinguishing ETD from EH as the underlying cause of aural fullness is important. Our findings raise the question whether Gd-MRI to rule out EH is indicated in patients with unexplained aural fullness, in particular after unsuccessful interventional treatment for ETD.
